In my site, I would like to implement a textbox where people can input a set of strings separated by a separator character.
For example the tags textbox at the bottom of this page: tags(strings) delimited by space(separator).
To make it more clear to the user, it would make a lot of sence to give each string a different background color or other visual hint.
I don't think this is possible with a regular input[text] control.
Do you deem it possible to create something like that with javascript? Has somebody done this before me already? Do you have any other suggestions?
Basic Steps
Put a textbox in a div and style it too hide it.
Make the div look like a text box.
In the onClick handler of the div, set the input focus to the hidden text box.
Handle the onKeyUp event of the hidden text box to capture text, format as necessary and alter the innerHtml of the div.
Tis quite straightforward. I'll leave you to write your formatter but basically you'd just splitString on separator as per the Semi-Working-Example.
Simple Outline
<html>
<head>
<script language="javascript" type="text/javascript">
function focusHiddenInput()
{
var txt = document.getElementById("txtHidden");
txt.focus();
}
function formatInputAndDumpToDiv()
{
alert('Up to you how to format');
}
</script>
</head>
<body>
<div onclick="focusHiddenInput();">
Some label here followed by a divved textbox:
<input id="txtHidden" style="width:0px;" onKeyPress="formatInputAndDumpToDiv()" type="text">
</div>
</body>
</html>
Semi-Working Example
You still need to extend the click handlers to account for tag deletion/editing/backspacing/etc via keyboard.... or you could just use a click event to pop up another context menu div. But with tags and spacer ids identified in the code below that should be pretty easy:
<html>
<head>
<script language="javascript" type="text/javascript">
var myTags=null;
function init()
{
document.getElementById("txtHidden").onkeyup= runFormatter;
}
function focusHiddenInput()
{
document.getElementById("txtHidden").focus();
}
function runFormatter()
{
var txt = document.getElementById("txtHidden");
var txtdiv = document.getElementById("txtBoxDiv");
txtdiv.innerHTML = "";
formatText(txt.value, txtdiv);
}
function formatText(tagText, divTextBox)
{
var tagString="";
var newTag;
var newSpace;
myTags = tagText.split(' ');
for(i=0;i<myTags.length;i++) {
newTag = document.createElement("span");
newTag.setAttribute("id", "tagId_" + i);
newTag.setAttribute("title", myTags[i]);
newTag.setAttribute("innerText", myTags[i]);
if ((i % 2)==0) {
newTag.style.backgroundColor='#eee999';
}
else
{
newTag.style.backgroundColor='#ccceee';
}
divTextBox.appendChild(newTag);
newTag.onclick = function(){tagClickedHandler(this);}
newSpace = document.createElement("span");
newSpace.setAttribute("id", "spId_" + i);
newSpace.setAttribute("innerText", " ");
divTextBox.appendChild(newSpace);
newSpace.onclick = function(){spaceClickedHandler(this);}
}
}
function tagClickedHandler(tag)
{
alert('You clicked a tag:' + tag.title);
}
function spaceClickedHandler(spacer)
{
alert('You clicked a spacer');
}
window.onload=init;
</script>
</head>
<body>
<div id="txtBoxDivContainer">
Enter tags below (Click and Type):<div id="txtBoxDiv" style="border: solid 1px #cccccc; height:20px;width:400px;" onclick="focusHiddenInput();"></div>
<input id="txtHidden" style="width:0px;" type="text">
</div>
</body>
</html>
Cursor
You could CSS the cursor using blink (check support) or otherwise just advance and hide as necessary an animated gif.
This is quite interesting. The short answer to your question is no. Not with the basic input element.
The real answer is: Maybe with some trickery with javascript.
Apparently Facebook does something close to this. When you write a new message to multiple persons in Facebook, you can type their names this sort of way. Each recognized new name is added a bit like an tag here and has an small cross next to it for removing it.
What they seem to do, is fake the input area size by drawing an input-looking box and removing all styling from the actual input with css. Then they have plenty of logic done with javascript so that if you have added an friend as a tag and start backspacing, it will remove the whole friends name at once. etc.
So, yes, it's doable, but takes plenty of effort and adds accessibility problems.
You can look how they do that at scripts like TinyMCE, which add such features to textareas. In textareas you can use HTML to colorize text.
You can use multiple textboxes
textbox1 <space> textbox2 <space> textbox3 ....
and so on... You can then apply the background-color style to each textbox.

first am sorry for bad English / grammar
am creating something where you show and hide.
but my problem is that when I click show/hide it only brings input box 1 on both buttons. and I want it to show/hide each box.
my problem is that. I don't want to use the id to define show/hide Element
because if I have more than 10 div with input boxes I have to define them all by getElementById I don't want that.
I want when I click on the show/hide it brings input box without getElementById
so that even if I have more then 10 input box to show I only click and show/hide without defining its id
function myFunction(event) {
var x = document.getElementById("mydv");
if (x.style.display === "none") {
x.style.display = "block";
} else {
x.style.display = "none";
}
x.parentNode.insertBefore(x, event.target.nextSibling);
}
document.addEventListener('click', function(event){
if(event.target.className.includes("dv1")){
myFunction(event);
}
});
<!DOCTYPE html>
<html>
<head>
<title> SHOW / Hide </title>
</head>
<body>
<ul>
<li>
<div id="mydv" style="display:none;">
<p>input box 1
<input type="text" name="textfield">
</p>
</div>
<button class="dv1">SHOW/HIDE</button>
</li>
<li><div id="mydv" style="display:none;">
<p>input box 2
<input type="text" name="textfield">
</p>
</div>
<button class="dv1">SHOW/HIDE</button></li>
</ul>
</body>
</html>
If you want to specify an element on a page, that can be similar in every way to other elements except perhaps text content or something else, realistically you need an id, as this is how JavaScript defines a unique element.
But what you can do, is change your HTML button, to contain a rel, which is an attribute, and then get that attribute and use that to specify which element id you're looking for.
You can then call a function and simply pass "this" as an argument.
HTML :
<button onclick="hideShow(this)" rel="mydv">Show/Hide</button>
JavaScript :
<script>
function hideShow(elem){
var ele = document.getElementById(elem.getAttribute("rel"));
if(ele.style.display == "none"){
ele.style.display = "block";
}
else{
ele.style.display = "none";
}
}
</script>
If you are absolutely abhorrent to using ID's, you can use child nodes and specify which child by number, but this means if ever you change anything, you will break your code, which is foolish. I recommend using unique ID's and simply changing your code in the above ways.
Short and lazy answer to your problems - if you are going to keep your current hierarchy, you can simply find DIV tag inside your LI parentNode (since its the only DIV tag).
Basically it goes like this - button press -> change focus from button to parentNode LI -> finds DIV.
in short - in function myFunction(event) change
var x = document.getElementById("mydv");
to
var x = event.target.parentNode.getElementsByTagName("DIV")[0];
Working example:
https://jsfiddle.net/w2a9zg46/1/
The problem is that getElementById refers to the first element with that id. It simply ignores everything else. Using the same id for more than one element is a bad practice. An id should be a unique reference to that element, use class instead.
I am trying to make the first character in a input field uppercase.
So far I have tried:
input:first-letter {text-transform:capitalize !important}
input:first-letter {text-transform:uppercase !important}
I have also tried to make the input field styled display:block; and display:inline-block; but with no luck.
I am using the latest version of chrome. If I look in the inspector the
input:first-letter {text-transform:capitalize !important} is flagged to be active but it does not work.
I am open to any Jquery solutions as well
Thanks,
:first-letter wont work on input field. but it works without that.
So change it as input {text-transform:capitalize;} it works fine.
see demo
it works fine without !important
input {text-transform:capitalize;}
<input/>
As you have mentioned in pure css way i have added the above method
Limitation: It will capitalize all words in the input box. In pure CSS it is not possible to capitalize only the first word as of now. you have to try the jquery way to do this as given below
Using jquery:-
using keyup event
$('input').keyup(function(){
if($(this).val().length>0){
var character = $(this).val().charAt(0);
if(character!=character.toUpperCase()){
$(this).val($(this).val().charAt(0).toUpperCase()+$(this).val().substr(1));
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input/>
To work even on mouse events:- (like cut paste in mouse)
Using propertychange event by $('input').bind('input propertychange', function() {
$('input').bind('input propertychange', function() {
if($(this).val().length>0){
var character = $(this).val().charAt(0);
if(character!=character.toUpperCase()){
$(this).val($(this).val().charAt(0).toUpperCase()+$(this).val().substr(1));
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input/>
You could use an onKeypress listener and capitalize the first character of the value. Keep in mind this function will run every time a key is pressed in that input
$( "#keypress" ).keypress(function() {
var val = $(this).val();
val = val.substr(0, 1).toUpperCase() + val.substr(1);
$(this).val(val);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="keypress">
For text output, you can easily make only the first character uppercase by css.
.mytable td {
text-transform:lowercase;
}
.mytable td:first-letter {
text-transform:uppercase;
}
When I select string (word) by doubleclick in textarea, then always select word and white space after text.
Maybe it's trivial question, but how to select text by doubleclick without white space after word?
I have this solution see example below.
What is your opinion?
<html>
<body>
<textarea cols=50 ondblclick="checkDblClick(event)">abc1space abc2space abc3space abc
</textarea>
<script>
function checkDblClickDelayed(target) {
while (target.value.substr(target.selectionEnd -1, 1) == " ") {
target.selectionEnd = target.selectionEnd - 1;
}
}
function checkDblClick(e) {
//we make a delay of 0ms to wait until the selection is in the final position
target = e.target;
setTimeout(function()
{
checkDblClickDelayed(target);
}
, 0);
}
</script>
</body>
</html>
The answer is... you can't.
The closest you can get is double clicking the text, and then Shift+Clicking it.
I'll try to explain:
I have numerous div classes, but for the sake of simplicity, let's say I only have 3.
Someone is viewing DIV 1, and I want to give them the option of only printing DIV 1, omitting 2 and 3.
However, on the same page, I would like to give them the option to ONLY PRINT DIV 2. Or only print DIV 3.
I think I get how you can omit certain things from getting printed. But how can you select a section here or there on the same page to be printed with a print link.
Thanks,
Tracy
You can use jQuery to show/hide divs. Read the jQuery tutorial:
http://docs.jquery.com/Tutorials
The code will look this way:
<script>
function showDiv(n) {
$('.divs').hide();
$('#div_'+n).show();
}
$(document).ready(function() { showDiv(1); });
</script>
<a href='javascript:showDiv(n)'>show div n</a>
<div class='divs' id='div_n'>I'm div n</div>
There are many related posts on printing div content, this particular question was still open though it was asked in '10.. Following JavaScript function can be used for printing content of a selected Div tag. Hope this helps. Declaimer: I used some of the existing answers, fixed/enhanced code/error(s) to work with (and tested on) IE-8.
function printDiv(divName) {
var divToPrint = document.getElementById(divName);
var newWin = window.open('', 'PrintWindow', 'width=400, height=400, top=100, left=100', '');
newWin.document.open();
newWin.document.write('<html><body onload="window.print()">' + divToPrint.innerHTML + '</body></html>');
newWin.document.close();
setTimeout(function () { newWin.close(); }, 10);
}
Call printDiv from anywhere in page or from within selected Div. Here is test link:
Print Customer Data
Print Order Data
Assign respective IDs to Div that is to be printed:
<div id="divCustomerData">Div Contents goes here... </div>
The only catch right now is it loses css styles. I'll update response when i get a chance to fix it. Thanks.

I would give each div an id, and then using the above plugin (i wrote) specify according to div id.
hi i have to implement find and replace functionality in my project. in this functionality there is one find and replace button on the top of contenteditable div. when user click on this button, popup window will open and ask for the search word when specify word and press find it will find word in that div only. and if match found it will highlight that word. so anybody tell me how can i highlight word in div. its urgent so please . thank you.
<div id="test" contenteditable="true">
this is test <font class='classname'> some text test</font>
</div>
i want to high light only test word not else
You will need to search through the div to find the word and then put that word into a span, and change the background color of the span.
Edit: I just noticed that you are not using CSS, so you will need to insert a font tag to change the color.
I just stole this from Sphix, the documentation tool:
/**
* highlight a given string on a jquery object by wrapping it in
* span elements with the given class name.
*/
jQuery.fn.highlightText = function(text, className) {
function highlight(node) {
if (node.nodeType == 3) {
var val = node.nodeValue;
var pos = val.toLowerCase().indexOf(text);
if (pos >= 0 && !jQuery.className.has(node.parentNode, className)) {
var span = document.createElement("span");
span.className = className;
span.appendChild(document.createTextNode(val.substr(pos, text.length)));
node.parentNode.insertBefore(span, node.parentNode.insertBefore(
document.createTextNode(val.substr(pos + text.length)),
node.nextSibling));
node.nodeValue = val.substr(0, pos);
}
}
else if (!jQuery(node).is("button, select, textarea")) {
jQuery.each(node.childNodes, function() {
highlight(this)
});
}
}
return this.each(function() {
highlight(this);
});
}
/**
* helper function to hide the search marks again
*/
hideSearchWords : function() {
$('.sidebar .this-page-menu li.highlight-link').fadeOut(300);
$('span.highlight').removeClass('highlight');
},
/**
* highlight the search words provided in the url in the text
*/
highlightSearchWords : function() {
var params = $.getQueryParameters();
var terms = (params.highlight) ? params.highlight[0].split(/\s+/) : [];
if (terms.length) {
var body = $('div.body');
window.setTimeout(function() {
$.each(terms, function() {
body.highlightText(this.toLowerCase(), 'highlight');
});
}, 10);
$('<li class="highlight-link"><a href="javascript:Documentation.' +
'hideSearchWords()">' + _('Hide Search Matches') + '</a></li>')
.appendTo($('.sidebar .this-page-menu'));
}
},
So, adding this to a js file in your site, any page with it that receives a highlight GET parameter will search and highlight the word in the page.
You can find a demo of the working code in:
http://sphinx.pocoo.org/intro.html?highlight=python
Note: This code needs jQuery, off course...
Its actually pretty easy using the prototype library:
<html>
<head>
<style type="text/css">
#content span {
background-color: yellow;
}
</style>
<script type="text/javascript" src="prototype.js"></script>
<script type="text/javascript">
Event.observe(window,'load',function(){
var htm = $('content').innerHTML;
$('content').innerHTML = htm.sub('my','<span>my</span>');
});
</script>
</head>
<body>
<div id="content">
This is the div containing my content.
</div>
</body>
</html>
This should get you started so you can implement the rest.
To highlight a word you have to select it somehow. One option is to surround the word with a span tag.
this is <span class="highlight">test</span> some text test
then specify CSS for the highlight class.
