how to transfer the uppercase letter to lowercase letter ?.
for example : THIS IS IS A LETTER to lowercase like This is a letter .
I do not want to change the full sentence ,just change except first letter rest all are want to change.
p:first-letter {
text-transform: capitalize;
}
<p>i am devat karetha</p>
I've always used a simple javascript function for cross-browser functionality - this works anywhere:
function sentenceCase(S) //1st upper,rest lower - S=string
{
if (!S) S="";
return S.substr(0,1).toUpperCase() + S.substr(1).toLowerCase();
}
In HTML, try this,
T<div style = "text-transform: lowercase"> IS A LETTER</div>
You could use a quick javascript function:
If this is an HTML form (so naive):
<input type="text" id="test"><input type="button" id="ok">
You could use the following function:
document.getElementById('ok').onclick = function() {
var first = document.getElementById('test').value.substr(0,1);
var rest= document.getElementById('test').value.substr(1);
document.getElementById('test').value = first.toUpperCase() + rest.toLowerCase();
}
The second example works "live" during insertion:
HTML
<input type="text" id="test">
JS
document.getElementById('test').onkeyup = function() {
this.value = this.value.substr(0,1).toUpperCase() + this.value.substr(1).toLowerCase();
}

Notice how you definitely should do it using two substrings (using substr(start[, end]) method), because to date there are only toUpperCase() and toLowerCase() methods for JS strings;
a toSentenceCase() would be handy in this case, but for what I know it does not exist...

I have an HTML text field that is 3 characters. If the user types 4 characters, I want the font size to shrink so that the four characters will fit.
Acrobat has this behavior for forms. I want this behavior in HTML.
That is, if I have a text field with 3 characters:
And the user types a 4, I want the text to shrink:
You need to use javascript.
This works by checking if the input can scroll, and if it can, it means that the content has overflowed, in which case the font size should get smaller.
Hope this helps!
function changefontsize() {
var myInput = document.getElementById('myInput');
if(isOverflown(myInput)) {
while (isOverflown(myInput)){
currentfontsize--;
myInput.style.fontSize = currentfontsize + 'px';
}
}else {
currentfontsize = 13;
myInput.style.fontSize = currentfontsize + 'px';
while (isOverflown(myInput)){
currentfontsize--;
myInput.style.fontSize = currentfontsize + 'px';
}
}
}
function isOverflown(element) {
return element.scrollWidth > element.clientWidth;
}
#myInput {
padding:5px;
border-radius:3px;
font-family:Arial;
width:100px;
font-size:13px;
height:20px;
}
Type Here -> <input type="text" id="myInput" onkeypress="changefontsize()" onchange="changefontsize()">
This is not possible with HTML/CSS - this solution uses JS+JQuery
Found this: https://github.com/vxsx/jquery.inputfit.js
Demo: http://vxsx.github.io/jquery.inputfit.js/
<input type="text" name="younameit" id="input">
<script type="text/javascript">
$('#input').inputfit();
</script>
I think what you want can be done with some very simple javascript methods. But, unfortunately there is no method of doing this in html or css. This next code is something I found, made by u/adactio. On github.
<script>
window.fitText( document.getElementById("responsive_headline") );
</script>
window.fitText( document.getElementById("responsive_headline"), 1.2 );
// turn the compressor up (font will shrink a bit more aggressively)
window.fitText( document.getElementById("responsive_headline"), 0.8 );
// turn the compressor down (font will shrink less aggressively)
Make sure to edit the 'responsive_headline' out!
Cheers!
Is this possible to add some tags or write some CSS code to make browsers render something like this html code:
<div lang="fa">1 2 3 4 5 6</div>
to this:
۱ ۲ ۳ ۴ ۵ ۶
?
Here I used Unicode shift since numerals in any Unicode group are placed in the same order as in Latin group (i.e. [0x0030 ... 0x0039]). So, for example, for Arabic-Indic group shift is 0x0630. unicode codepros
I hope this is you want.
$("[lang='fa']").text(function(i, val) {
return val.replace(/\d/g, function(v) {
return String.fromCharCode(v.charCodeAt(0) + 0x0630);
});
});
div {
font-size: 18px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div lang="fa">0123456789</div>
I guess it's not reachable by pure HTML/CSS.
You can write a script that get all divs by selector and change locale according to the attribute on your dom-node.
On the example output will be "١٬٢٣٤".
var number = 1234;
number.toLocaleString('ar-EG');
I was wondering how can i automatically make first character of the word in an input area
Currently my code is
Name:<input type='text' name='name' class='name' placeholder='Enter your name here'/>
You can try this: DEMO
Name:<input type='text' name='name' class='name' style="text-transform: capitalize;" placeholder='Enter your name here'/>
or add text-transform: capitalize; in your name in css.
The problem with using CSS (text-transform: capitalize) is that when the form gets submitted, the name will be submitted with a lowercase name.
The CSS works well for cosmetics but not for functionality.
You can use jQuery to force capitalization functionality in your input boxes:
<script type="text/javascript">
jQuery.noConflict();
jQuery(document).ready(function($) {
$('.name').keyup(function(event) {
var textBox = event.target;
var start = textBox.selectionStart;
var end = textBox.selectionEnd;
textBox.value = textBox.value.charAt(0).toUpperCase() + textBox.value.slice(1).toLowerCase();
textBox.setSelectionRange(start, end);
});
});
</script>
Put this code between the <head> </head> on the page where your form is located.
Above jQuery will also force ALL CAPS to Capitalize.
Check out the Fiddle here: https://jsfiddle.net/cgaybba/6rps8hfo/
I think it should also be mentioned that if the form is on mobile, you can just use the autocapitalize attribute. see here for documentation
Try this
HTML CODE
<input type='text' name='name' class='name' placeholder='Enter your name here'/>
CSS CODE
<style>
.name
{
text-transform:capitalize;
}
</style>
Update you css
.name { text-transform: capitalize; }
The good side of using JS is that when the user submits the form, it retains the capitalized input values, but using css when the form is submitted, it looses the capitalized values (for frontend only).
Note for CSS: make sure you don't have any overriding styles else use !important.
//For CSS
input { text-transform: capitalize }
//For JS
$('.your-input').on('change keydown paste', function(e) {
if (this.value.length = 1) {}
var $this_val = $(this).val();
this_val = $this_val.toLowerCase().replace(/\b[a-z]/g, function(char) {
return char.toUpperCase();
});
$(this).val(this_val);
});
Just include → style="text-transform:capitalize;" inside your input tag.
I don't know if this is possible but I would like to have an input field where I would have a value that is not editable by the user.
However, I don't want the input field to be "readonly" because I still want the user to be able to add text after the value.
If you have any idea on how to do this, let me know please that would help me a lot.
EDIT: I use html forms.
You can position the text on top of the input field to make it look as if it is inside it. Something like this:
<input type="text" name="year" style="width:3.5em;padding-left:1.5em;font:inherit"><span style="margin-left:-3em;margin-right:10em;">19</span>
This way your input field will start with "19" which can not be edited, and the user can add information behind this.
Basically what you do is set the input field to a fixed width, so that you know how much negative margin-left to give the span with your text in it in order for it to be positioned exactly at the start of the input field.
You might need to fiddle with the margin-left of the span depending on the rest of your css.
Then also adding pedding-left to the input field, to make sure the user starts typing after your text and not under it.
font:inherit should make sure both your text and the text typed by the user are in the same font.
And if you want to put anything to the right of this input field, do add margin-right to the span with your text, as otherwise other content might start running over your input field as well.
seems a little weird to me ..why not just use a text output and afterwards the input field?
like sometimes used for the birthdate (although, maybe not anymore..)
birthyear: 19[input field]
edit:
with some javascript stuff you could realise something like that you asked for, though
an input field with text and catching keystrokes within that field while only allowing some after what you want to be always there - but, well, you would need to use js ..and if its just for that, Id rather say its not necessary
edit:
if you want to use a trick just for the viewer you could use a background-image/border-style that surrounds a text and the input field, thus making it look like text and input are the same input-box.
Sounds like you want placeholder text. In HTML5 you can set the placeholder attribute on any input element. This will work in modern browsers.
<input type="email" placeholder="jappleseed#appletree.com" name="reg_email" />
Now, for older browsers this won't work. You'll need a JavaScript alternative to provide the same UI value.
This can work for all browsers:
<input type="text" value="Search" onfocus="if (this.value == 'Search') {this.value = '';}" onblur="if (this.value == '') {this.value = 'Search';}">
but it's not recommended because there is a better way (really, it's a combination of the first two approaches): Use HTML5 markup for new browsers; jQuery and modernizr for old browsers. This way you can have only one set of code that will support all user cases.
Taken directly from webdesignerwall.com:
<script src="jquery.js"></script>
<script src="modernizr.js"></script>
<script>
$(document).ready(function(){
if(!Modernizr.input.placeholder){
$('[placeholder]').focus(function() {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
input.removeClass('placeholder');
}
}).blur(function() {
var input = $(this);
if (input.val() == '' || input.val() == input.attr('placeholder')) {
input.addClass('placeholder');
input.val(input.attr('placeholder'));
}
}).blur();
$('[placeholder]').parents('form').submit(function() {
$(this).find('[placeholder]').each(function() {
var input = $(this);
if (input.val() == input.attr('placeholder')) {
input.val('');
}
})
});
}
</script>
[You'll need both jquery.js and modernizr.js installed in the same folder as your webpage.]
Note: I have a feeling that a little more research might reveal that modernizr isn't needed for this at all, though I could be wrong about that particular point.
Perhaps, then, you want a select menu?
<select name="mySelectMenu">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
</select>
Sorry if this isn't what you want either. I'm grasping at straws because what you are asking for is very vague. Maybe you should give an example of what one of these 'editable but not editable' inputs would be used for.
Also, you could use a select and a text input.
The main problem is to determine the position of the cursor. This can be done e.g. using the following function:
function getCaret(el) {
var pos = -1;
if (el.selectionStart) {
pos = el.selectionStart;
}
else if (document.selection) {
el.focus();
var r = document.selection.createRange();
if (r != null) {
var re = el.createTextRange();
var rc = re.duplicate();
re.moveToBookmark(r.getBookmark());
rc.setEndPoint('EndToStart', re);
pos = rc.text.length;
}
}
return pos;
}
Now you can install an event handler for the key press and check whether the pressed key was inside the immutable part of the value of the textarea. If it was there the event handler returns false, otherwise true. This behavior can be wrapped into a simple object:
function Input(id, immutableText) {
this.el = document.getElementById(id);
this.el.value = immutableText;
this.immutableText = immutableText;
this.el.onkeypress = keyPress(this);
}
function keyPress(el) {
return function() {
var self = el;
return getCaret(self.el) >= self.immutableText.length;
}
}
Input.prototype.getUserText = function() {
return this.el.value.substring(this.immutableText.length);
};
var input = new Input("ta", "Enter your name: ");
var userText = input.getUserText();
You can check it on jsFiddle (use Firefox or Chrome).
I came up with this:
```
if (e.target.value == '' || e.target.value.length <= 3) {
e.target.value = '+91-';
}
```
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.
