Lets say I add a text box of length of 50px, And I want to count the exact number of characters (including whitespace) that perfectly fits inside that text box, I mean no character should be allowed to be typed inside the textbox that require the sliding of whole line toward left; I mean, in another other-words, we need to disallow the typist to further insert any letter as the line reaches up to the length of the text box. Can we anyhow solve this by JavaScrip? Thanks for the help in advance, any help would be appreciated.
The whole logic is flawed as it would depend also on the size of the text inside the input. I'd put instead a limit of chars to be entered that don't go beyond. Using maxlength input attribute.
Anyways if you really wanna go this route, which I think is an overkill and not needed, then you can:
Make use of CanvasRenderingContext2D.measureText, docs here
In order to do that you'd have to create a hidden canvas element where to mimic your input text.
After that you will need to check on input if the text goes beyond the input width and avoid any further keystrokes but still allow for deletion.
Find attached an example snippet, not optimised, of what I am talking about.
const form = document.querySelector('#form'),
input = form.querySelector('input')
const createAppendCanvas = form => {
const canvas = document.createElement('Canvas')
form.appendChild(canvas)
}
createAppendCanvas(form)
const getTextMetrics = inputText => {
const canvas = document.querySelector('canvas'),
textWidth = Math.ceil(canvas.getContext('2d').measureText(inputText).width) + 10
return textWidth
}
const disableTyping = (event, input) => {
const inputText = event.target.value,
inputWidth = input.clientWidth
if (getTextMetrics(inputText) >= inputWidth) {
event.preventDefault()
return false
}
}
input.addEventListener('keypress', event => disableTyping(event, input))
input {
width: 50px;
}
canvas {
display: none;
}
<form id="form">
<input type="text" />
</form>
As #mel-macaluso rightly points out, this is a very big rabbit hole to go down, and the standard practice is to use the maxlength attribute to limit the number of characters.
*Edit: You can also set the width of the input using em, which is proportional to the font size. (The name em was originally a reference to the width of the capital M in the typeface and size being used, which was often the same as the point size ref) A combination of width in em and maxlength will give a very rough approximation of what you may be trying to achieve.
However if you really want to be able to limit input based text length, this would serve as a very simplistic example of how you might get started.
Edit: I recommend #mel-macaluso's answer: he added an example using CanvasRenderingContext2D.measureText(), which I suspect is much more efficient than getBoundingClientRect.
First some disclaimers:
This example doesn't take into account clipboard actions. That's a pretty big problem, and you'd be talking a lot more code to try to account for it (way beyond the scope of what can reasonably be done here).
It's also rather resource intensive. The process doing a getBoundingClientRect, forces the browser to reflow the document contents an extra time. Depending on the size of the page this can be a big deal, and it's not something to be done lightly.
var inp = document.getElementById('test');
// get font for input
var style = getComputedStyle(inp);
var maxWidth = inp.getBoundingClientRect().width;
var sizeTest = document.createElement('span');
// set font for span to match input
sizeTest.style.font = style.font;
inp.addEventListener('keydown', function(e){
if(e.ctrlKey || e.altKey) return;
if(e.key && e.key.length===1) {
sizeTest.textContent = inp.value;
document.body.append(sizeTest);
var w = sizeTest.getBoundingClientRect().width;
sizeTest.remove();
console.log(maxWidth, w, e.key, e.code);
if(w>maxWidth) e.preventDefault();
}
})
<input id='test'/>
So why is it so complex to do something like this? Fonts are tricky things. You have variable width (proportional) fonts, kerning, ligatures, etc. It's very complex, and browsers don't provide access to most of this information.
So if you want to know how long a segment of text is, you generally have to put it in a span with the same font settings and then request the bounding dimensions.
Here's neat solution using nested spans (with a contenteditable inner span) as a proxy input.
// Identifiers and dynamic styling
const innerSpan = document.querySelector("span.inner"),
outerSpan = document.querySelector("span.outer");
/* Threshold should be at least one character-width less than outerSpan.
(This formula was pretty close for my few tests;
for more precision and less flexibility, you can hard-code a value.) */
const estMaxCharWidth = innerSpan.offsetHeight / 1.7,
thresholdWidth = outerSpan.offsetWidth - estMaxCharWidth;
innerSpan.style.minWidth = `${Math.floor(thresholdWidth)-3}px`; // defaults to 0
innerSpan.style.minHeight = `${Math.floor(outerSpan.offsetHeight)-2}px`
// Listeners
innerSpan.addEventListener("focus", customOutline);
innerSpan.addEventListener("keydown", checkKeyAndWidth);
innerSpan.addEventListener("blur", removeOutlineAndHandleText);
// Functions
function checkKeyAndWidth(e){
// Runs when user presses a key, Conditionally prevents input
if(e.code == "Enter" || e.keyCode == 13){
e.preventDefault(); // Don't insert a new line
e.target.blur(); // (In production, set the focus to another element)
}
else{
// Some keys besides Enter are important, More could be added
const whitelistCodes = ["Backspace", "Tab", "Escape", "ArrowLeft", "ArrowRight", "Insert", "Delete"];
const whitelistKeyCodes = [8,9,27,37,39,45,46];
// If the inner span is wide enough, stop accepting characters
let acceptingCharacters = e.target.offsetWidth <= thresholdWidth;
if(!acceptingCharacters && !whitelistCodes.includes(e.code) && !whitelistKeyCodes.includes(e.keyCode) && !whitelistKeyCodes.includes(e.which)){
// Unauthorized incoming keystroke
e.preventDefault();
}
}
}
function customOutline(){
// Runs when span gets focus, Needed for accessibility due to CSS settings
outerSpan.style.borderColor = "DeepSkyBlue";
}
function removeOutlineAndHandleText(){
// Runs when focus is lost
outerSpan.style.borderColor = "Gray";
if(innerSpan.length < 1){ innerSpan.innerHTML = " "; } // force content
/* Since this is not a real input element, now might be the time to do something with the entered text */
}
.outer{
display: inline-block;
position: relative;
width: 100px; /* Defaults to 0 */
padding: 0;
border: 1px solid gray;
}
.inner{
display: inline-block;
position: relative;
top: 0;
height: 100%;
margin: 0;
outline: none; /* Don't do this without calling customOutline on focus */
}
<!-- requires that browser supports `contenteditable` -->
<span class="outer">
<!-- space character in innerSpan may improve cross-browser rendering -->
<span class="inner" contenteditable="true"> </span>
</span>
I'm trying to add some text resize functionality using this code:
$('#text-resize a').click(function(){
var currentValue = $('#page-body').css('fontSize');
var currentSize = parseFloat(currentValue, 10);
var fontUnit = currentValue.slice(-2);
var newSize = currentSize;
if ($(this).attr('rel') == 'decrease'){
if (currentSize > 13){
var newSize = currentSize / 1.2;
}
}
else if ($(this).attr('rel') == 'increase'){
if (currentSize < 19){
var newSize = currentSize * 1.2;
}
}
else {
newSize = 1;
fontUnit = 'em';
}
newSize += fontUnit;
$('#page-body').css('fontSize', newSize);
return false;
});
I know it's not the cleanest code, but my problem is that at some point (either getting or setting the font size for #page-body decimal points are being lost.
For example, I start with a value of 16px (from my CSS file) and when I increase it gets calculated to 19.2px. If I increase again, an alert of the currentValue (I have left out the alert) says it's 19px.
Can anyone tell me why decimal places are being ignored and how to prevent that?
If it helps, my starting CSS includes:
body { font-size: 16px; }
#page-body { font-size: 1em; }
Thanks
A font size can only be a whole number of pixels, so when you set the font-size the browser casts the invalid font size to something it can use. The next time you get it, it's an integer number.
Since you're setting the font size on an element identified by ID, you should store the size in a variable and only set (never get) the element css font size.
For example, see http://jsfiddle.net/Qfzpb/
Sub-pixel rendering is inconsistent between browsers.
Font size can be a <length>, and a <length> is a <number> (with or without a decimal point) immediately followed by a unit identifier (e.g., px, em, etc.).
http://www.w3.org/TR/CSS21/fonts.html#font-size-props
CSS 3 says " UAs should support reasonably useful ranges and precisions. " Open-to-interpretation wording as 'reasonable' and 'useful':
http://dev.w3.org/csswg/css3-values/#numeric-types
$('#page-body').css('fontSize')
This may return different values(depending on the used browser).
Usually (in modern browsers) jQuery gets the value by using getComputedStyle() .
The returned value here is the value used by the browser, not the value the style-property is set to.
You may use this instead:
var currentValue = document.getElementById('page-body').style.fontSize
||
$('#page-body').css('fontSize');
See the fiddle to determine the differences: http://jsfiddle.net/doktormolle/DMWhh/
I'm currently working on an internal sales application for the company I work for, and I've got a form that allows the user to change the delivery address.
Now I think it would look much nicer, if the textarea I'm using for the main address details would just take up the area of the text in it, and automatically resize if the text was changed.
Here's a screenshot of it currently.
Any ideas?
#Chris
A good point, but there are reasons I want it to resize. I want the area it takes up to be the area of the information contained in it. As you can see in the screen shot, if I have a fixed textarea, it takes up a fair wack of vertical space.
I can reduce the font, but I need address to be large and readable. Now I can reduce the size of the text area, but then I have problems with people who have an address line that takes 3 or 4 (one takes 5) lines. Needing to have the user use a scrollbar is a major no-no.
I guess I should be a bit more specific. I'm after vertical resizing, and the width doesn't matter as much. The only problem that happens with that, is the ISO number (the large "1") gets pushed under the address when the window width is too small (as you can see on the screenshot).
It's not about having a gimick; it's about having a text field the user can edit that won't take up unnecessary space, but will show all the text in it.
Though if someone comes up with another way to approach the problem I'm open to that too.
I've modified the code a little because it was acting a little odd. I changed it to activate on keyup, because it wouldn't take into consideration the character that was just typed.
resizeIt = function() {
var str = $('iso_address').value;
var cols = $('iso_address').cols;
var linecount = 0;
$A(str.split("\n")).each(function(l) {
linecount += 1 + Math.floor(l.length / cols); // Take into account long lines
})
$('iso_address').rows = linecount;
};
Facebook does it, when you write on people's walls, but only resizes vertically.
Horizontal resize strikes me as being a mess, due to word-wrap, long lines, and so on, but vertical resize seems to be pretty safe and nice.
None of the Facebook-using-newbies I know have ever mentioned anything about it or been confused. I'd use this as anecdotal evidence to say 'go ahead, implement it'.
Some JavaScript code to do it, using Prototype (because that's what I'm familiar with):
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<script src="http://www.google.com/jsapi"></script>
<script language="javascript">
google.load('prototype', '1.6.0.2');
</script>
</head>
<body>
<textarea id="text-area" rows="1" cols="50"></textarea>
<script type="text/javascript" language="javascript">
resizeIt = function() {
var str = $('text-area').value;
var cols = $('text-area').cols;
var linecount = 0;
$A(str.split("\n")).each( function(l) {
linecount += Math.ceil( l.length / cols ); // Take into account long lines
})
$('text-area').rows = linecount + 1;
};
// You could attach to keyUp, etc. if keydown doesn't work
Event.observe('text-area', 'keydown', resizeIt );
resizeIt(); //Initial on load
</script>
</body>
</html>
PS: Obviously this JavaScript code is very naive and not well tested, and you probably don't want to use it on textboxes with novels in them, but you get the general idea.
One refinement to some of these answers is to let CSS do more of the work.
The basic route seems to be:
Create a container element to hold the textarea and a hidden div
Using Javascript, keep the textarea’s contents synced with the div’s
Let the browser do the work of calculating the height of that div
Because the browser handles rendering / sizing the hidden div, we avoid
explicitly setting the textarea’s height.
document.addEventListener('DOMContentLoaded', () => {
textArea.addEventListener('change', autosize, false)
textArea.addEventListener('keydown', autosize, false)
textArea.addEventListener('keyup', autosize, false)
autosize()
}, false)
function autosize() {
// Copy textarea contents to div browser will calculate correct height
// of copy, which will make overall container taller, which will make
// textarea taller.
textCopy.innerHTML = textArea.value.replace(/\n/g, '<br/>')
}
html, body, textarea {
font-family: sans-serif;
font-size: 14px;
}
.textarea-container {
position: relative;
}
.textarea-container > div, .textarea-container > textarea {
word-wrap: break-word; /* make sure the div and the textarea wrap words in the same way */
box-sizing: border-box;
padding: 2px;
width: 100%;
}
.textarea-container > textarea {
overflow: hidden;
position: absolute;
height: 100%;
}
.textarea-container > div {
padding-bottom: 1.5em; /* A bit more than one additional line of text. */
visibility: hidden;
}
<div class="textarea-container">
<textarea id="textArea"></textarea>
<div id="textCopy"></div>
</div>
Here's another technique for autosizing a textarea.
Uses pixel height instead of line height: more accurate handling of line wrap if a proportional font is used.
Accepts either ID or element as input
Accepts an optional maximum height parameter - useful if you'd rather not let the text area grow beyond a certain size (keep it all on-screen, avoid breaking layout, etc.)
Tested on Firefox 3 and Internet Explorer 6
Code:
(plain vanilla JavaScript)
function FitToContent(id, maxHeight)
{
var text = id && id.style ? id : document.getElementById(id);
if (!text)
return;
/* Accounts for rows being deleted, pixel value may need adjusting */
if (text.clientHeight == text.scrollHeight) {
text.style.height = "30px";
}
var adjustedHeight = text.clientHeight;
if (!maxHeight || maxHeight > adjustedHeight)
{
adjustedHeight = Math.max(text.scrollHeight, adjustedHeight);
if (maxHeight)
adjustedHeight = Math.min(maxHeight, adjustedHeight);
if (adjustedHeight > text.clientHeight)
text.style.height = adjustedHeight + "px";
}
}
Demo:
(uses jQuery, targets on the textarea I'm typing into right now - if you have Firebug installed, paste both samples into the console and test on this page)
$("#post-text").keyup(function()
{
FitToContent(this, document.documentElement.clientHeight)
});
Probably the shortest solution:
jQuery(document).ready(function(){
jQuery("#textArea").on("keydown keyup", function(){
this.style.height = "1px";
this.style.height = (this.scrollHeight) + "px";
});
});
This way you don't need any hidden divs or anything like that.
Note: you might have to play with this.style.height = (this.scrollHeight) + "px"; depending on how you style the textarea (line-height, padding and that kind of stuff).
Here's a Prototype version of resizing a text area that is not dependent on the number of columns in the textarea. This is a superior technique because it allows you to control the text area via CSS as well as have variable width textarea. Additionally, this version displays the number of characters remaining. While not requested, it's a pretty useful feature and is easily removed if unwanted.

if (window.Widget == undefined) window.Widget = {};
Widget.Textarea = Class.create({
initialize: function(textarea, options)
{
this.textarea = $(textarea);
this.options = $H({
'min_height' : 30,
'max_length' : 400
}).update(options);
this.textarea.observe('keyup', this.refresh.bind(this));
this._shadow = new Element('div').setStyle({
lineHeight : this.textarea.getStyle('lineHeight'),
fontSize : this.textarea.getStyle('fontSize'),
fontFamily : this.textarea.getStyle('fontFamily'),
position : 'absolute',
top: '-10000px',
left: '-10000px',
width: this.textarea.getWidth() + 'px'
});
this.textarea.insert({ after: this._shadow });
this._remainingCharacters = new Element('p').addClassName('remainingCharacters');
this.textarea.insert({after: this._remainingCharacters});
this.refresh();
},
refresh: function()
{
this._shadow.update($F(this.textarea).replace(/\n/g, '<br/>'));
this.textarea.setStyle({
height: Math.max(parseInt(this._shadow.getHeight()) + parseInt(this.textarea.getStyle('lineHeight').replace('px', '')), this.options.get('min_height')) + 'px'
});
var remaining = this.options.get('max_length') - $F(this.textarea).length;
this._remainingCharacters.update(Math.abs(remaining) + ' characters ' + (remaining > 0 ? 'remaining' : 'over the limit'));
}
});
Create the widget by calling new Widget.Textarea('element_id'). The default options can be overridden by passing them as an object, e.g. new Widget.Textarea('element_id', { max_length: 600, min_height: 50}). If you want to create it for all textareas on the page, do something like:
Event.observe(window, 'load', function() {
$$('textarea').each(function(textarea) {
new Widget.Textarea(textarea);
});
});
Here is a solution with JQuery:
$(document).ready(function() {
var $abc = $("#abc");
$abc.css("height", $abc.attr("scrollHeight"));
})
abc is a teaxtarea.
Check the below link:
http://james.padolsey.com/javascript/jquery-plugin-autoresize/
$(document).ready(function () {
$('.ExpandableTextCSS').autoResize({
// On resize:
onResize: function () {
$(this).css({ opacity: 0.8 });
},
// After resize:
animateCallback: function () {
$(this).css({ opacity: 1 });
},
// Quite slow animation:
animateDuration: 300,
// More extra space:
extraSpace:20,
//Textarea height limit
limit:10
});
});
Just revisiting this, I've made it a little bit tidier (though someone who is full bottle on Prototype/JavaScript could suggest improvements?).
var TextAreaResize = Class.create();
TextAreaResize.prototype = {
initialize: function(element, options) {
element = $(element);
this.element = element;
this.options = Object.extend(
{},
options || {});
Event.observe(this.element, 'keyup',
this.onKeyUp.bindAsEventListener(this));
this.onKeyUp();
},
onKeyUp: function() {
// We need this variable because "this" changes in the scope of the
// function below.
var cols = this.element.cols;
var linecount = 0;
$A(this.element.value.split("\n")).each(function(l) {
// We take long lines into account via the cols divide.
linecount += 1 + Math.floor(l.length / cols);
})
this.element.rows = linecount;
}
}
Just it call with:
new TextAreaResize('textarea_id_name_here');
I've made something quite easy. First I put the TextArea into a DIV. Second, I've called on the ready function to this script.
<div id="divTable">
<textarea ID="txt" Rows="1" TextMode="MultiLine" />
</div>
$(document).ready(function () {
var heightTextArea = $('#txt').height();
var divTable = document.getElementById('divTable');
$('#txt').attr('rows', parseInt(parseInt(divTable .style.height) / parseInt(altoFila)));
});
Simple. It is the maximum height of the div once it is rendered, divided by the height of one TextArea of one row.
I needed this function for myself, but none of the ones from here worked as I needed them.
So I used Orion's code and changed it.
I added in a minimum height, so that on the destruct it does not get too small.
function resizeIt( id, maxHeight, minHeight ) {
var text = id && id.style ? id : document.getElementById(id);
var str = text.value;
var cols = text.cols;
var linecount = 0;
var arStr = str.split( "\n" );
$(arStr).each(function(s) {
linecount = linecount + 1 + Math.floor(arStr[s].length / cols); // take into account long lines
});
linecount++;
linecount = Math.max(minHeight, linecount);
linecount = Math.min(maxHeight, linecount);
text.rows = linecount;
};
Like the answer of #memical.
However I found some improvements. You can use the jQuery height() function. But be aware of padding-top and padding-bottom pixels. Otherwise your textarea will grow too fast.
$(document).ready(function() {
$textarea = $("#my-textarea");
// There is some diff between scrollheight and height:
// padding-top and padding-bottom
var diff = $textarea.prop("scrollHeight") - $textarea.height();
$textarea.live("keyup", function() {
var height = $textarea.prop("scrollHeight") - diff;
$textarea.height(height);
});
});
My solution not using jQuery (because sometimes they don't have to be the same thing) is below. Though it was only tested in Internet Explorer 7, so the community can point out all the reasons this is wrong:
textarea.onkeyup = function () { this.style.height = this.scrollHeight + 'px'; }
So far I really like how it's working, and I don't care about other browsers, so I'll probably apply it to all my textareas:
// Make all textareas auto-resize vertically
var textareas = document.getElementsByTagName('textarea');
for (i = 0; i<textareas.length; i++)
{
// Retain textarea's starting height as its minimum height
textareas[i].minHeight = textareas[i].offsetHeight;
textareas[i].onkeyup = function () {
this.style.height = Math.max(this.scrollHeight, this.minHeight) + 'px';
}
textareas[i].onkeyup(); // Trigger once to set initial height
}
Here is an extension to the Prototype widget that Jeremy posted on June 4th:
It stops the user from entering more characters if you're using limits in textareas. It checks if there are characters left. If the user copies text into the textarea, the text is cut off at the max. length:
/**
* Prototype Widget: Textarea
* Automatically resizes a textarea and displays the number of remaining chars
*

*/
if (window.Widget == undefined) window.Widget = {};
Widget.Textarea = Class.create({
initialize: function(textarea, options){
this.textarea = $(textarea);
this.options = $H({
'min_height' : 30,
'max_length' : 400
}).update(options);
this.textarea.observe('keyup', this.refresh.bind(this));
this._shadow = new Element('div').setStyle({

#memical had an awesome solution for setting the height of the textarea on pageload with jQuery, but for my application I wanted to be able to increase the height of the textarea as the user added more content. I built off memical's solution with the following:
$(document).ready(function() {
var $textarea = $("p.body textarea");
$textarea.css("height", ($textarea.attr("scrollHeight") + 20));
$textarea.keyup(function(){
var current_height = $textarea.css("height").replace("px", "")*1;
if (current_height + 5 <= $textarea.attr("scrollHeight")) {
$textarea.css("height", ($textarea.attr("scrollHeight") + 20));
}
});
});
It's not very smooth but it's also not a client-facing application, so smoothness doesn't really matter. (Had this been client-facing, I probably would have just used an auto-resize jQuery plugin.)
For those that are coding for IE and encounter this problem. IE has a little trick that makes it 100% CSS.
<TEXTAREA style="overflow: visible;" cols="100" ....></TEXTAREA>
You can even provide a value for rows="n" which IE will ignore, but other browsers will use. I really hate coding that implements IE hacks, but this one is very helpful. It is possible that it only works in Quirks mode.
Internet Explorer, Safari, Chrome and Opera users need to remember to explicidly set the line-height value in CSS. I do a stylesheet that sets the initial properites for all text boxes as follows.
<style>
TEXTAREA { line-height: 14px; font-size: 12px; font-family: arial }
</style>
Here is a function I just wrote in jQuery to do it - you can port it to Prototype, but they don't support the "liveness" of jQuery so elements added by Ajax requests will not respond.
This version not only expands, but it also contracts when delete or backspace is pressed.
This version relies on jQuery 1.4.2.
Enjoy ;)
