I am using TextArea of AntDesign, when I input, say, 2-3 paragraphs in it, and hit enter to display it in a row, but it displays everything in one paragraph. I want the exact formatting that I did while entering in the text area. How to do that?
I am simply using Text area -
<TextArea
rows={2}
style={{ width: "100%" }}
defaultValue={this.state.value}
onClick={this.handleValue}
/>
and to display on right side-
<div>{this.state.value}</div>
EXPECTED

Hey, how are you doing today? I am fine. i hope your are fine do give me a call when you are free. contact - 1234567890
You can use the pre tag for displaying the content as entered.
I have created following example using vanilla JS. You can implement the same in react.
<textarea id="tarea" rows="2" style="width: 100%" onclick="handleValue()">
</textarea>
<p id="display"></p>
<script>
function handleValue() {
var tarea = document.getElementById('tarea');
var disp = document.getElementById('display');
disp.innerHTML = '<pre>' + tarea.value + '</pre>';
}
</script>
For eg:
<pre>{this.state.value}</pre>
should do the trick.
Hope this helps! Cheers.
So I don't think there is a simple way of doing so (even if the way of doing is not so hard).
What you'll have to do is get each line of the TextArea, you should be able to get this with something like this :
var textArea = document.getElementById("my-text-area");
var arrayOfLines = textArea.value.split("\n");
Source: https://stackoverflow.com/questions/9196954/how-to-read-line-by-line-of-a-text-area-html-tag
Once you have arrayOfLines, you can output the text like it was typed in with a little for() loop.
Provided below are two options for this task:
On keypress "Enter", append a newline char to the line. When displaying the text, split on newline. CodeSandbox example, listen for keycode
function App() {
const [text, setText] = React.useState("");
function handleChange(e) {
if (e.key === "Enter") {
setText(`${e.target.value}\n`);
}
setText(e.target.value);
}
return (
<div>
<TextArea
rows={4}
value={text}
onChange={handleChange}
onPressEnter={handleChange}
/>
{text.length > 0 && text.split("\n").map((l, i) => <p key={i}>{l}</p>)}
</div>
);
}
Use pre HTML tag. This is simple, however it renders the text as a monospace font by default. CodeSandbox example, using pre tag
function App() {
const [text, setText] = React.useState("");
function handleChange(e) {
setText(e.target.value);
}
return (
<div>
<TextArea
rows={4}
value={text}
onChange={handleChange}
onPressEnter={handleChange}
/>
<pre>{text}</pre>
</div>
);
}
As AdityaSrivast said, you can use pre tags. But to wrap the text you should add below CSS.
<style>
pre {
overflow-x: auto;
white-space: pre-wrap;
white-space: -moz-pre-wrap;
white-space: -pre-wrap;
white-space: -o-pre-wrap;
word-wrap: break-word;
}
</style>
Otherwise, texts will show as one line.
In my opinion, the problem is in style={{ width: "100%" }}. Try to limit TextAreas width. For example: style={{ width: "100px" }}
I am doing a phonegap app. When I am trying type="date" input field as shown below, it shows date picker in iPhone as I expected but it doesn't show the placeholder I have given. I found the same issue here in SO, but no solution anywhere.
<input placeholder="Date" class="textbox-n" type="date" id="date">
It may not be appropriate... but it helped me.
What I did is start with a text input field, then change the type to a date input when the input is in focus.
<input
placeholder="Date"
class="textbox-n"
type="text"
onfocus="(this.type='date')"
id="date" />
If you use mvp's method but add the onblur event to change it back to a text field so the placeholder text appears again when the input field looses focus. It just makes the hack a little bit nicer.
<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date" />
I ended up using the following.
Regarding Firefox comment(s): Generally, Firefox will not show any text placeholder for inputs type date.
But as this is a Cordova/PhoneGap question this should be of no concern (Unless you want to develop against FirefoxOS).
input[type="date"]:not(.has-value):before{
color: lightgray;
content: attr(placeholder);
}
<input type="date" placeholder="MY PLACEHOLDER" onchange="this.className=(this.value!=''?'has-value':'')">
As of today (2016), I have successfully used those 2 snippets (plus they work great with Bootstrap4).
Input data on the left, placeholder on the left
input[type=date] {
text-align: right;
}
input[type="date"]:before {
color: lightgrey;
content: attr(placeholder) !important;
margin-right: 0.5em;
}
Placeholder disappear when clicking
input[type="date"]:before {
color: lightgrey;
content: attr(placeholder) !important;
margin-right: 0.5em;
}
input[type="date"]:focus:before {
content: '' !important;
}
I used this in my css:
input[type="date"]:before{
color:lightgray;
content:attr(placeholder);
}
input[type="date"].full:before {
color:black;
content:""!important;
}
and put somenthing like this into javascript:
$("#myel").on("input",function(){
if($(this).val().length>0){
$(this).addClass("full");
}
else{
$(this).removeClass("full");
}
});
it works for me for mobile devices (Ios8 and android). But I used jquery inputmask for desktop with input text type. This solution it's a nice way if your code run on ie8.
Based on deadproxor and Alessio answers, I would try only using CSS:
input[type="date"]::before{
color: #999;
content: attr(placeholder) ": ";
}
input[type="date"]:focus::before {
content: "" !important;
}
And if you need to make the placeholder invisible after writing something in the input, we could try using the :valid and :invalid selectors, if your input is a required one.
EDIT
Here the code if you are using required in your input:
input[type="date"]::before {
color: #999999;
content: attr(placeholder);
}
input[type="date"] {
color: #ffffff;
}
input[type="date"]:focus,
input[type="date"]:valid {
color: #666666;
}
input[type="date"]:focus::before,
input[type="date"]:valid::before {
content: "" !important;
}
<input type="date" placeholder="Date" required>
I took jbarlow idea, but I added an if in the onblur function so the fields only change its type if the value is empty
<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.value == '' ? this.type='text' : this.type='date')" id="date">
According to the HTML standard:
The following content attributes must not be specified and do not apply to the element: accept, alt, checked, dirname, formaction, formenctype, formmethod, formnovalidate, formtarget, height, inputmode, maxlength, minlength, multiple, pattern, placeholder, size, src, and width.
It works for me:
input[type='date']:after {
content: attr(placeholder)
}
I used this whit jQuery:
http://jsfiddle.net/daviderussoabram/65w1qhLz/
$('input[type="date"], input[type="datetime"], input[type="datetime-local"], input[type="month"], input[type="time"], input[type="week"]').each(function() {
var el = this, type = $(el).attr('type');
if ($(el).val() == '') $(el).attr('type', 'text');
$(el).focus(function() {
$(el).attr('type', type);
el.click();
});
$(el).blur(function() {
if ($(el).val() == '') $(el).attr('type', 'text');
});
});
Found a better way to solve your problem.
I think this will help you. when focused out, the box will change type into text so it will show your placeholder. when focused in, its type changes into date so the calendar view will be shown.
<input placeholder="Date" class="textbox-n" type="text" onfocusin="(this.type='date')" onfocusout="(this.type='text')" id="date">
<input placeholder="01-01-2021" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date" />
Adressing the problem in the current correct answer "clicking the field shows the onscreen keyboard instead of the datepicker":
The problem is caused by the Browser behaving according to the type of input when clicking (=text). Therefore it is necessary to stop from focussing on the input element (blur) and then restart focus programmatically on the input element which was defined as type=date by JS in the first step. Keyboard displays in phonenumber-mode.
<input placeholder="Date" type="text" onfocus="this.type='date';
this.setAttribute('onfocus','');this.blur();this.focus();">
To summarize the date inputs problem:
You have to display them (i.e. avoid display:none) otherwise the input UI will not be triggered ;
a placeholder is contradictory with them (as per the spec, and because they have to display a specific UI) ;
converting them to another input type for the unfocused time do allows placeholders, but focus then triggers the wrong input UI (keyboard), at least for a small time, because focus events cannot be cancelled.
inserting (before) or adding (after) content doesn't prevent the date input value to be displayed.
The solution I found to meet those requirements is to use the usual trick to style native form elements : ensure the element is displayed but not visible, and display its expected style through its associated label. Typically, the label will display as the input (including a placeholder), but over it.
So, an HTML like:
<div class="date-input>
<input id="myInput" type="date">
<label for="myInput">
<span class="place-holder">Enter a date</span>
</label>
</div>
Could be styled as:
.date-input {
display: inline-block;
position: relative;
}
/* Fields overriding */
input[type=date] + label {
position: absolute; /* Same origin as the input, to display over it */
background: white; /* Opaque background to hide the input behind */
left: 0; /* Start at same x coordinate */
}
/* Common input styling */
input[type=date], label {
/* Must share same size to display properly (focus, etc.) */
width: 15em;
height: 1em;
font-size: 1em;
}
Any event (click, focus) on such an associated label will be reflected on the field itself, and so trigger the date input UI.
Should you want to test such a solution live, you can run this Angular version from your tablet or mobile.
try my solution. I use 'required' attribute to get know whether input is filled and if not I show the text from attribute 'placeholder'
//HTML
<input required placeholder="Date" class="textbox-n" type="date" id="date">
//CSS
input[type="date"]:not(:valid):before {
content: attr(placeholder);
// style it like it real placeholder
}
Took me a while figuring this one out, leave it as type="text", and add onfocus="(this.type='date')", just as shown above.
I even like the onBlur idea mentioned above
<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date">
Hope this helps anyone who didn't quite gather whats going on above
SO what i have decided to do finally is here and its working fine on all mobile browsers including iPhones and Androids.
$(document).ready(function(){
$('input[type="date"]').each(function(e) {
var $el = $(this),
$this_placeholder = $(this).closest('label').find('.custom-placeholder');
$el.on('change',function(){
if($el.val()){
$this_placeholder.text('');
}else {
$this_placeholder.text($el.attr('placeholder'));
}
});
});
});
label {
position: relative;
}
.custom-placeholder {
#font > .proxima-nova-light(26px,40px);
position: absolute;
top: 0;
left: 0;
z-index: 10;
color: #999;
}
<label>
<input type="date" placeholder="Date">
<span class="custom-placeholder">Date</span>
</label>
Date
Im working with ionicframework and solution provided by #Mumthezir is almost perfect. In case if somebody would have same problem as me(after change, input is still focused and when scrolling, value simply dissapears) So I added onchange to make input.blur()
<input placeholder="Date" class="textbox-n" type="text" onfocus=" (this.type='date')" onchange="this.blur();" id="date">
You can
set it as type text
convert to date on focus
make click on it
...let user check date
on change store the value
set input to type text
set text type input value to the stored value
like this...
$("#dateplaceholder").change(function(evt) {
var date = new Date($("#dateplaceholder").val());
$("#dateplaceholder").attr("type", "text");
$("#dateplaceholder").val(date.getDate() + "/" + (date.getMonth() + 1) + "/" + date.getFullYear());
});
$("#dateplaceholder").focus(function(evt) {
$("#dateplaceholder").attr("type", "date");
setTimeout('$("#dateplaceholder").click();', 500);
});
$("#dateplaceholder").attr("type", "text");
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<input type="date" id="dateplaceholder" placeholder="Set the date" />
Found a better way to handle user basic comprehension with mouseover and opening datepicker on click :
<input type="text" onfocus="(this.type='date')" onmouseover="(this.type = 'date')" onblur="(this.value ? this.type = 'date' : this.type = 'text')" id="date_start" placeholder="Date">
Also hide webkit arrow and make it 100% wide to cover the click :
input[type="date"] {
position: relative;
}
input[type="date"]::-webkit-calendar-picker-indicator {
position: absolute;
height: 100%;
width: 100%;
opacity: 0;
left: 0;
right: 0;
top:0;
bottom: 0;
}
Expanding on #mvp's solution with unobtrusive javascript in mind, here's the approach:
HTML:
<input type="text" placeholder="Date" class="js-text-date-toggle">
Javascript:
$('.js-text-date-toggle').on('focus', function() {
$(this).attr('type', 'date');
}).on('blur', function() {
$(this).attr('type', 'text');
});
I think all you have to do is change the model to say the date field is nullable and then put [Required] on it if it is required. If you do this the placeholder text does appear.
Hey so I ran into the same issue last night and figured out a combination of all of your answer and some sparkling magic are doing a good job:
The HTML:
<input type="date" name="flb5" placeholder="Datum" class="datePickerPlaceHolder"/>
The CSS:
#media(max-width: 1024px) {
input.datePickerPlaceHolder:before {
color: #A5A5A5; //here you have to match the placeholder color of other inputs
content: attr(placeholder) !important;
}
}
The jQuery:
$(document).ready(function() {
$('input[type="date"]').change(function(){
if($(this).val().length < 1) {
$(this).addClass('datePickerPlaceHolder');
} else {
$(this).removeClass('datePickerPlaceHolder');
}
});
});
Explanation:
So, what is happening here, first of all in the HTML, this is pretty straight forward just doing a basic HMTL5-date-input and set a placeholder.
Next stop: CSS, we are setting a :before-pseudo-element to fake our placeholder, it just takes the placeholder's attribute from the input itself. I made this only available down from a viewport width of 1024px - why im going to tell later.
And now the jQuery, after refactoring a couple of times I came up with this bit of code which will check on every change if there is a value set or not, if its not it will (re-)add the class, vice-versa.
KNOW ISSUES:
there is a problem in chrome with its default date-picker, thats what the media-query is for. It will add the placeholder infront of the default 'dd.mm.yyyy'-thing. You could also set the placeholder of the date-input to 'date: ' and adjust the color incase of no value inside the input...for me this resulted in some other smaller issues so i went with just not showing it on 'bigger' screens
hope that helps!
cheerio!
From Angular point of view I managed to put a placeholder in input type date element.
First of all I defined the following css:
.placeholder {
color: $text-grey;
}
input[type='date']::before {
content: attr(placeholder);
}
input::-webkit-input-placeholder {
color: $text-grey;
}
The reason why this is neccessary is that if css3 content has different color that the normal placeholder, so I had to use a common one.
<input #birthDate
class="birthDate placeholder"
type="date"
formControlName="birthDate"
placeholder="{{getBirthDatePlaceholder() | translate}}"
[class.error]="!onboardingForm.controls.birthDate.valid && onboardingForm.controls.birthDate.dirty"
autocomplete="off"
>
Then in the template used a viewchild birthDate attribute, to be able to access this input from the component. And defined an angular expression on the placeholder attribute, which will decide if we show the placeholder or not. This is the major drawback of the solution, is that you have to manage the visibility of the placeholder.
#ViewChild('birthDate') birthDate;
getBirthDatePlaceholder() {
if (!this.birthDate) {
return;
} else {
return this.birthDate.nativeElement.value === '' ?
'ONBOARDING_FORM_COMPONENT.HINT_BIRTH_DATE' :
'';
}
}
<input placeholder="Date" type="text" onMouseOver="(this.type='date')" onMouseOut="(this.type='text')" id="date" class="form-control">
Revised code of mumthezir
If you're only concerned with mobile:
input[type="date"]:invalid:before{
color: rgb(117, 117, 117);
content: attr(placeholder);
}
I'm surprised there's only one answer with an approach similar to the one I used.
I got the inspiration from #Dtipson's comment on #Mumthezir VP's answer.
I use two inputs for this, one is a fake input with type="text" on which I set the placeholder, the other one is the real field with type="date".
On the mouseenter event on their container, I hide the fake input and show the real one, and I do the opposite on the mouseleave event. Obviously, I leave the real input visibile if it has a value set on it.
I wrote the code to use pure Javascript but if you use jQuery (I do) it's very easy to "convert" it.
// "isMobile" function taken from this reply:
// https://stackoverflow.com/a/20293441/3514976
function isMobile() {
try { document.createEvent("TouchEvent"); return true; }
catch(e) { return false; }
}
var deviceIsMobile = isMobile();
function mouseEnterListener(event) {
var realDate = this.querySelector('.real-date');
// if it has a value it's already visible.
if(!realDate.value) {
this.querySelector('.fake-date').style.display = 'none';
realDate.style.display = 'block';
}
}
function mouseLeaveListener(event) {
var realDate = this.querySelector('.real-date');
// hide it if it doesn't have focus (except
// on mobile devices) and has no value.
if((deviceIsMobile || document.activeElement !== realDate) && !realDate.value) {
realDate.style.display = 'none';
this.querySelector('.fake-date').style.display = 'block';
}
}
function fakeFieldActionListener(event) {
event.preventDefault();
this.parentElement.dispatchEvent(new Event('mouseenter'));
var realDate = this.parentElement.querySelector('.real-date');
// to open the datepicker on mobile devices
// I need to focus and then click on the field.
realDate.focus();
realDate.click();
}
var containers = document.getElementsByClassName('date-container');
for(var i = 0; i < containers.length; ++i) {
var container = containers[i];
container.addEventListener('mouseenter', mouseEnterListener);
container.addEventListener('mouseleave', mouseLeaveListener);
var fakeDate = container.querySelector('.fake-date');
// for mobile devices, clicking (tapping)
// on the fake input must show the real one.
fakeDate.addEventListener('click', fakeFieldActionListener);
// let's also listen to the "focus" event
// in case it's selected using a keyboard.
fakeDate.addEventListener('focus', fakeFieldActionListener);
var realDate = container.querySelector('.real-date');
// trigger the "mouseleave" event on the
// container when the value changes.
realDate.addEventListener('change', function() {
container.dispatchEvent(new Event('mouseleave'));
});
// also trigger the "mouseleave" event on
// the container when the input loses focus.
realDate.addEventListener('blur', function() {
container.dispatchEvent(new Event('mouseleave'));
});
}
.real-date {
display: none;
}
/* a simple example of css to make
them look like it's the same element */
.real-date,
.fake-date {
width: 200px;
height: 20px;
padding: 0px;
}
<div class="date-container">
<input type="text" class="fake-date" placeholder="Insert date">
<input type="date" class="real-date">
</div>
I tested this also on an Android phone and it works, when the user taps on the field the datepicker is shown. The only thing is, if the real input had no value and the user closes the datepicker without choosing a date, the input will remain visible until they tap outside of it. There's no event to listen to to know when the datepicker closes so I don't know how to solve that.
I don't have an iOS device to test it on.
This might help in some situation.
<input type="text" id="date" onclick="this.type='date'" onblur="this.type='text'" placeholder="Date" class="textbox-n" name="myDate" />
HTML:
<div>
<input class="ui-btn ui-btn-icon-right ui-corner-all ui-icon-calendar ui-shadow" id="inputDate" type="date"/>
<h3 id="placeholder-inputDate">Date Text</h3>
</div>
JavaScript:
$('#inputDate').ready(function () {
$('#placeholder-inputDate').attr('style'
, 'top: ' + ($('#placeholder-inputDate').parent().position().top + 10)
+ 'px; left: ' + ($('#placeholder-inputDate').parent().position().left + 0) + 'px; position: absolute;');
$('#inputDate').attr('style'
, 'width: ' + ($('#placeholder-inputDate').width() + 32) + 'px;');
});
Here is another possible hack not using js and still using css content. Note that as :after is not supported on some browser for inputs, we need to select the input in another way, same for content attr('')
input[type=date]:invalid+span:after {
content:"Birthday";
position:absolute;
left:0;
top:0;
}
input[type=date]:focus:invalid+span:after {
display:none;
}
input:not(:focus):invalid {
color:transparent;
}
label.wrapper {
position:relative;
}
<label class="wrapper">
<input
type="date"
required="required"
/>
<span></span>
</label>
curently I have this for HTML and CSS respectively:.....How would I contruct CSS and html that looks the same using a <div>. The one I created had horizontal scrolling and looked crazy.
<textarea class="textarea_readonly" readonly="readonly" name="mcRemarkOld" rows="7" cols="100" scrolling="auto"></textarea>
.textarea_readonly
{
background-color: #DDDDD0;
margin: 0px;
width: 100%;
}
Instead of trying to mimic a div, replace the textarea using JavaScript. Usage (run on load):
var textarea = document.getElementsByName("mcRemarkOld")[0];
turnTextAreaIntoDiv(textarea);
function turnTextAreaIntoDiv(elem){
var div = document.createElement("div");
// Copy significant attributes, customize.
div.className = elem.className;
div.style.cssText = elem.style.cssText;
div.id = elem.id;
div.name = elem.name;
div.innerHTML = elem.innerHTML; //`<a>` turns in <a>
elem.parentNode.replaceChild(div, elem);
}
Fiddle: http://jsfiddle.net/7bTNH/
I have ghost text in textfields that disappear when you focus on them using HTML5's placeholder attribute:
<input type="text" name="email" placeholder="Enter email"/>
I want to use that same mechanism to have multiline placeholder text in a textarea, maybe something like this:
<textarea name="story" placeholder="Enter story\n next line\n more"></textarea>
But those \ns show up in the text and don't cause newlines... Is there a way to have a multiline placeholder?
UPDATE: The only way I got this to work was utilizing the jQuery Watermark plugin, which accepts HTML in the placeholder text:
$('.textarea_class').watermark('Enter story<br/> * newline', {fallback: false});
For <textarea>s the spec specifically outlines that carriage returns + line breaks in the placeholder attribute MUST be rendered as linebreaks by the browser.
User agents should present this hint to the user when the element's value is the empty string and the control is not focused (e.g. by displaying it inside a blank unfocused control). All U+000D CARRIAGE RETURN U+000A LINE FEED character pairs (CRLF) in the hint, as well as all other U+000D CARRIAGE RETURN (CR) and U+000A LINE FEED (LF) characters in the hint, must be treated as line breaks when rendering the hint.
Also reflected on MDN: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/textarea#attr-placeholder
FWIW, when I try on Chrome 63.0.3239.132, it does indeed work as it says it should.
On most (see details below) browsers, editing the placeholder in javascript allows multiline placeholder.
As it has been said, it's not compliant with the specification and you shouldn't expect it to work in the future (edit: it does work).
This example replaces all multiline textarea's placeholder.
var textAreas = document.getElementsByTagName('textarea');
Array.prototype.forEach.call(textAreas, function(elem) {
elem.placeholder = elem.placeholder.replace(/\\n/g, '\n');
});
<textarea class="textAreaMultiline"
placeholder="Hello, \nThis is multiline example \n\nHave Fun"
rows="5" cols="35"></textarea>
JsFiddle snippet.
Expected result
Based on comments it seems some browser accepts this hack and others don't.
This is the results of tests I ran (with browsertshots and browserstack)
Chrome: >= 35.0.1916.69
Firefox: >= 35.0 (results varies on platform)
IE: >= 10
KHTML based browsers: 4.8
Safari: No (tested = Safari 8.0.6 Mac OS X 10.8)
Opera: No (tested <= 15.0.1147.72)
Fused with theses statistics, this means that it works on about 88.7% of currently (Oct 2015) used browsers.
Update: Today, it works on at least 94.4% of currently (July 2018) used browsers.
I find that if you use a lot of spaces, the browser will wrap it properly. Don't worry about using an exact number of spaces, just throw a lot in there, and the browser should properly wrap to the first non space character on the next line.
<textarea name="address" placeholder="1313 Mockingbird Ln Saginaw, MI 45100"></textarea>
There is actual a hack which makes it possible to add multiline placeholders in Webkit browsers, Chrome used to work but in more recent versions they removed it:
First add the first line of your placeholder to the html5 as usual
<textarea id="text1" placeholder="Line 1" rows="10"></textarea>
then add the rest of the line by css:
#text1::-webkit-input-placeholder::after {
display:block;
content:"Line 2\A Line 3";
}
If you want to keep your lines at one place you can try the following. The downside of this is that other browsers than chrome, safari, webkit-etc. don't even show the first line:
<textarea id="text2" placeholder="." rows="10"></textarea>
then add the rest of the line by css:
#text2::-webkit-input-placeholder{
color:transparent;
}
#text2::-webkit-input-placeholder::before {
color:#666;
content:"Line 1\A Line 2\A Line 3\A";
}
Demo Fiddle
It would be very great, if s.o. could get a similar demo working on Firefox.
According to MDN,
Carriage returns or line-feeds within the placeholder text must be treated as line breaks when rendering the hint.
This means that if you just jump to a new line, it should be rendered correctly. I.e.
<textarea placeholder="The car horn plays La Cucaracha.
You can choose your own color as long as it's black.
The GPS has the voice of Darth Vader.
"></textarea>
should render like this:
If you're using AngularJS, you can simply use braces to place whatever you'd like in it: Here's a fiddle.
<textarea rows="6" cols="45" placeholder="{{'Address Line1\nAddress Line2\nCity State, Zip\nCountry'}}"></textarea>
React:
If you are using React, you can do it as follows:
placeholder={'Address Line1\nAddress Line2\nCity State, Zip\nCountry'}
This can apparently be done by just typing normally,
<textarea name="" id="" placeholder="Hello awesome world. I will break line now
Yup! Line break seems to work."></textarea>
The html5 spec expressly rejects new lines in the place holder field. Versions of Webkit /will/ insert new lines when presented with line feeds in the placeholder, however this is incorrect behaviour and should not be relied upon.
I guess paragraphs aren't brief enough for w3 ;)
If your textarea have a static width you can use combination of non-breaking space and automatic textarea wrapping. Just replace spaces to nbsp for every line and make sure that two neighbour lines can't fit into one. In practice line length > cols/2.
This isn't the best way, but could be the only cross-browser solution.
<textarea class="textAreaMultiligne"
placeholder="Hello, This is multiligne example Have Fun "
rows="5" cols="35"></textarea>
With Vue.js:
<textarea name="story" :placeholder="'Enter story\n next line\n more'"></textarea>
in php with function chr(13) :
echo '<textarea class="form-control" rows="5" style="width:100%;" name="responsable" placeholder="NOM prénom du responsable légal'.chr(13).'Adresse'.chr(13).'CP VILLE'.chr(13).'Téléphone'.chr(13).'Adresse de messagerie" id="responsable"></textarea>';
The ASCII character code 13 chr(13) is called a Carriage Return or CR
You can try using CSS, it works for me. The attribute placeholder=" " is required here.
<textarea id="myID" placeholder=" "></textarea>
<style>
#myID::-webkit-input-placeholder::before {
content: "1st line...\A2nd line...\A3rd line...";
}
</style>
Bootstrap + contenteditable + multiline placeholder
Demo: https://jsfiddle.net/39mptojs/4/
based on the #cyrbil and #daniel answer
Using Bootstrap, jQuery and https://github.com/gr2m/bootstrap-expandable-input to enable placeholder in contenteditable.
Using "placeholder replace" javascript and adding "white-space: pre" to css, multiline placeholder is shown.
Html:
<div class="form-group">
<label for="exampleContenteditable">Example contenteditable</label>
<div id="exampleContenteditable" contenteditable="true" placeholder="test\nmultiple line\nhere\n\nTested on Windows in Chrome 41, Firefox 36, IE 11, Safari 5.1.7 ...\nCredits StackOveflow: .placeholder.replace() trick, white-space:pre" class="form-control">
</div>
</div>
Javascript:
$(document).ready(function() {
$('div[contenteditable="true"]').each(function() {
var s=$(this).attr('placeholder');
if (s) {
var s1=s.replace(/\\n/g, String.fromCharCode(10));
$(this).attr('placeholder',s1);
}
});
});
Css:
.form-control[contenteditable="true"] {
border:1px solid rgb(238, 238, 238);
padding:3px 3px 3px 3px;
white-space: pre !important;
height:auto !important;
min-height:38px;
}
.form-control[contenteditable="true"]:focus {
border-color:#66afe9;
}
If you're using a framework like Aurelia that allows one to bind view-model properties to HTML5 element properties, then you can do the following:
<textarea placeholder.bind="placeholder"></textarea>
export class MyClass {
placeholder = 'This is a \r\n multiline placeholder.'
}
In this case the carriage return and line feed is respected when bound to the element.
Watermark solution in the original post works great. Thanks for it.
In case anyone needs it, here is an angular directive for it.
(function () {
'use strict';
angular.module('app')
.directive('placeholder', function () {
return {
restrict: 'A',
link: function (scope, element, attributes) {
if (element.prop('nodeName') === 'TEXTAREA') {
var placeholderText = attributes.placeholder.trim();
if (placeholderText.length) {
// support for both '\n' symbol and an actual newline in the placeholder element
var placeholderLines = Array.prototype.concat
.apply([], placeholderText.split('\n').map(line => line.split('\\n')))
.map(line => line.trim());
if (placeholderLines.length > 1) {
element.watermark(placeholderLines.join('<br>\n'));
}
}
}
}
};
});
}());
I have a form with some text areas that allow a scroll bar when the text exceeds the text box. The user would like to be able to print the screen, and this text is not visible. How do I make all of the text visible for just printing? Am I better of making a print to pdf link or something?
You cannot solve this problem with CSS alone.
Why Pure-CSS Solutions are Insufficient (with demo)
Let me convince you the answers involving print stylesheets and overflow: visible are insufficient. Open this page and look at the source. Just what they suggested, right? Now print preview it (in, say, Chrome 13 on OS X, like me). Note that you can only see a line or two of the note when you attempt to print!
Here’s the URL for my test case again: https://alanhogan.github.io/web-experiments/print_textarea.html
Solutions:
A JavaScript link that opens a new window and writes the contents of the textarea to it for printing. Or:
When the textarea is updated, copy its contents to another element that that his hidden for screen but displayed when printed.
(If your textarea is read-only, then a server-side solution is also workable.)
Note that textareas treat whitespace differently than HTML does by default, so you should consider applying the CSS white-space: pre-wrap; in the new window you open or to your helper div, respectively. IE7 and older do not understand pre-wrap however, so if that is an issue, either accept it or use a workaround for them. or make the popup window actually plain text, literally served with a media type text/plain (which probably requires a server-side component).
The “Print Helper” Solution (with code + demo)
I have created a demo of one JavaScript technique.
The core concept is copying the textarea contents to another print helper. Code follows.
HTML:
<textarea name="textarea" wrap="wrap" id="the_textarea">
</textarea>
<div id="print_helper"></div>
CSS (all / non-print):
/* Styles for all media */
#print_helper {
display: none;
}
CSS (print):
/* Styles for print (include this after the above) */
#print_helper {
display: block;
overflow: visible;
font-family: Menlo, "Deja Vu Sans Mono", "Bitstream Vera Sans Mono", Monaco, monospace;
white-space: pre;
white-space: pre-wrap;
}
#the_textarea {
display: none;
}
Javascript (with jQuery):
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript">
jQuery(function($){
function copy_to_print_helper(){
$('#print_helper').text($('#the_textarea').val());
}
$('#the_textarea').bind('keydown keyup keypress cut copy past blur change', function(){
copy_to_print_helper(); // consider debouncing this to avoid slowdowns!
});
copy_to_print_helper(); // on initial page load
});
</script>
Again, the successful JavaScript-based demo is at https://alanhogan.github.io/web-experiments/print_textarea_js.html.
Loop through each of your text areas and move the content to a holder
window.onbeforeprint = function () {
$('.print-content').remove();
$('textarea').each(function () {
var text = $(this).val();
$(this).after('<p class="well print-content">' + text + '</p>');
});
}
And use the following CSS
.print-content {
display: none !important;
}
#media print {
.print-content {
display: block !important;
}
textarea {display: none !important;}
}
I recently ran into the same issue. My solution was to duplicate the content into form controls for editing and into divs for printing.
In my Head I put a print stylesheet.
<link rel="stylesheet" href="printform.css" type="text/css" media="print" />
In printform.css I put the following
.screenOnly { display: none; }
.printOnly { display: inline-block; }
For textareas (and other field types that were causing problems) I used the following code
<textarea class="screenOnly" name="myTextArea"><?php echo (htmlspecialchars ($_POST ['myTextArea'])); ?></textarea>
<div class="printOnly"><?php echo (htmlspecialchars ($_POST ['myTextArea'])); ?></div>
When displayed on screen the textareas are shown and the divs duplicating their content are hidden. When printing the opposite applies.
I know you already picked an answer to this question but while using the print stylesheet is a good idea it didn't describe a specific solution. Setting overflow:visible on the textarea (my first idea) didn't work so I ended up going with the solution above. If you're still having difficulties I hope this helps you out
Just encourter the problem recently too. Thanks for Alan H's posts. It works perfect with Chrome and Safari. However, with IE and Firefox, the issue is that the last several pages(page elements after textarea) will be missing from printing(FF), missing pages and overlapped layout(IE9).
Another finding that will be helpful to solve the issue is, you can set textarea's rows properties correctly as the control's height says to make it work with CSS overflow:visable stuff. All browsers seems to respect the rows property while printing.
This seems to work for applying to all elements that have overflowing content:
$("textarea").each(function () {
var Contents = $(this).val();
if ($(this)[0].scrollHeight > $(this).height()) {
$(this).after("<div class='print-helper'>" + Contents + "</div>");
$(this).addClass("no-print");
}
});
This is an easy fix with CSS, given that most users aren't really bothered about printing a bit of extra blank space. Just target a minimum height for textareas when printing:
#media print {
textarea {
min-height: 500px;
}
}
Tag that onto the end of your CSS with a min-height that is comfortably enough when you look at it in Print Preview.
With the usage of pure CSS it is not possible to prepare the textarea for printing.
It is necessary to add some javacript magic to the text area or add a hidden field.
There are a couple of solutions, that have been mentioned here:
Hidden paragraph or div
Using Javascript to extent the size of the textarea
1. Hidden paragraph or div
HTML & CSS:
<textarea>Sample Text</textarea>
<div class="hidden-div">Sample Text</div>
<style>
.hidden-div{display: none;}
#media print{
.hidden-div{display:block;}
}
</style>
2. Javascript
You could use a js library e.g https://github.com/thomasjo/jquery-autoresize
$(function() {
$("textarea").autoResize()
})
Adding onto Alan's answer above, if you have multiple instances of this problem on the same page, then you can use data-* attributes to handle all at once. Sample:
var $printOnlyArr = $('.print-only');
for (var i = 0; i < $printOnlyArr.length; i++) {
var $printOnly = $($printOnlyArr[i]);
var textSource = $printOnly.data('textsource');
if (textSource) {
$printOnly.text($("#" + textSource).val());
}
}
.print-only {
display: none;
}
#media print {
.print-only {
display: block;
}
.no-print {
display: none;
}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<textarea class="form-control no-print" maxlength="2000" id="txtAdditionalComments"></textarea>
<div class="print-only" data-textsource="txtAdditionalComments"></div>
I had this same problem. My project is React, I was a semnaticUi TextArea component. The Text that could only be seen by scrolling down in the Textarea aka the "overflow" could not be seen in the print view when I press the print screen button.
Solution :)
I just used a normal paragraph tag instead and set css white-space: pre-wrap on a div that enclosed the p tag.
Worked for me!
try this using jQuery. Redefine height of all textareas based on quantity of lines.
Attention: this code change the textarea on screen too
window.onbeforeprint = function () {
$('textarea').each(function () {
var lines = Math.round($(this).val().split('\n').length * 1.6) ; //multiply to 1.6 to consider spacing between lines
$(this).height(lines+'em');
});
}
Define a separate CSS for print media like this <link rel="stylesheet" href="print.css" type="text/css" media="print" /> and for the text area, define the overflow attribute as
overflow: visible;
I use this in my styling:
PRE.print {
display:none;
}
#media print {
TEXTAREA {
display:none;
}
PRE.print {
display:block;
width:90%; /* fixes margin issues in some funky browsers */
white-space: pre-wrap; /* css-3 */
white-space: -moz-pre-wrap; /* Mozilla, since 1999 */
white-space: -pre-wrap; /* Opera 4-6 */
white-space: -o-pre-wrap; /* Opera 7 */
word-wrap: break-word; /* Internet Explorer 5.5+ */
font-family:monospace,sans;
}
}
Then, after every TEXTAREA, I use a PRE with class "print" like so:
<textarea id="message" name="message" rows="10" cols="80" onblur="updatePrint('#message')"><?= $MESSAGE ?></textarea>
<pre id="message-print" class="print">
<?= $MESSAGE ?>
</pre>
...note the PHP I used -- you can switch with your programming language. And then this code above needs the following function, assuming you have jQuery library loaded:
<script type="text/javascript">
function updatePrint(sID) {
$(sID + '-print').text($(sID)[0].value);
}
</script>
The way this all works
The way this works is that I'm basically loading content twice into the page, but using the stylesheet to hide content not suitable for the printer like the TEXTAREA.
You can change the PRE styling as you wish. However, I use monospace in case someone was wanting to print HTML code that they typed into the field and wanted it to format nicely.
The onblur event helps capture a need to update the related PRE.
Note you can also do the stylesheet stuff via the media attribute on a link rel in the HEAD section of your HTML, using things like media="all not print" and media="print".
