Really simple jQuery character countdown in textarea

By Geoff Muskett

Looking to build a Twitter-like textarea character countdown to show your users how much space they have remaining?

Good. See below.

See the Pen Really easy textarea character countdown by Geoff Muskett (@geoffmuskett) on CodePen.6289

I’ve seen a few tutorials online but they seem to make it more complex than it needs to be. Just a few lines of jQuery does the trick.

1. Set a variable for the max number of characters:

var maxLength = 100;

2. Use the keyup event on the textarea, which fires each time a key is pressed when the textarea is in focus. Ideal:

$('textarea').keyup(function() {

3. Check the value and get the length of it, store it in a variable:

var length = $(this).val().length;

4. Take that value away from your max width:

var length = maxLength-length;

5. Put the result somewhere on the page:

When I try to run this through visual studio on IE, it doesn't work. Any idea why? It works in IE when looking at your page.

Hi Reynald, sorry for the slow reply. I really need to set up notifications for comments!

I wouldn't worry about not working in visual studio, I've never used it, but if the site works in the wild thats fine.

That said, you could try keypress instead of keyup. I don't think support is that great on older windows phones for that through.

Best of luck

$('#mesage').prop('maxlength', '1500');

Mix characters with line breaks and the text counter counts wrongly.

If you're allowing HTML in there you'd something more advanced than this. Perhaps you could detect wether < or > keys have been pressed and ignore them. Or look for
with regex perhaps.

I think it's worth mentioning that "maxlength" is not supported on textareas in IE prior v10 in case legacy browser support is a requirement.

Carriage returns count as 2 characters. It would help to add logic with regex to count and adjust your character countdown based on the number of carriage returns.

Also using
var maxLength = $(this).attr('maxlength');
will dynamically obtain a value from the textarea attribute for maxlength.

Thanks for taking the time to post this, but there is a small bug with your script. Press and hold enter (while focused on the textarea) and then start typing. The count doesn't update properly and I can still type 2 characters afterwards. Thats in Chrome. Hope this helps.

Really simple? This is *too* simple, because it doesn't allow for changes made via the mouse or Edit menu.

var maxchar = 10;
$('#count').html(maxchar+' of '+maxchar);
$('#message').attr('maxlength', maxchar);
$('#message').on("keydown", function(e){
var len = $('#message').val().length;
if (len >= maxchar && e.keyCode != 8)
else if(len <= maxchar && e.keyCode == 8){
if(len <= maxchar && len != 0)
$('#count').html(maxchar+' of '+(maxchar - len +1));
else if(len == 0)
$('#count').html(maxchar+' of '+(maxchar - len));
$('#count').html(maxchar+' of '+(maxchar - len-1));

To address issues raised by Chris and Anonymous, I made a slight change from this:
$('textarea').keyup(function() {
to this:
$('textarea').on('change keyup paste', function() {
