Max characters in textarea with jquery?

Here it goes. Anything beyond character limit will be removed.

Here it goes. Anything beyond character limit will be removed. $('textarea').

Keypress(function(e) { var tval = $('textarea').val(), tlength = tval. Length, set = 10, remain = parseInt(set - tlength); $('p'). Text(remain); if (remain Which!

== 0 && e. CharCode! == 0) { $('textarea').

Val((tval). Substring(0, tlength - 1)) } }) Check working example at jsfiddle.net/JCehq/1.

Like this solution but it chops the last char off when you are at the last position and move backwards – Steve Claridge Mar 13 at 21:22 @steve I updated the answer. To prevent this from happening we need to add && e. Which!

== 0 && e. CharCode! == 0 – Hussein Mar 13 at 22:14 yup, that seems to be working.

A simple way to do this is to set the text in the textarea to a substring of the full amount. You can find an example here: mediacollege.com/internet/javascript/for....

Returning false and using .keypress() instead of .keyup() stops input once the length has been reached. Here's the example in a jsFiddle: jsfiddle.net/p43BH/1/ Updated to allow backspace.

The problem with that is once you reach the limit you can't go back to update it. – Bill Mar 13 at 21:01 Yeah, forgot about that. You need to use the event parameter to keypress() and check for backspace.

I've updated the fiddle. – Steve Claridge Mar 13 at 21:06 You can't go back using the arrow keys. Return false; or preventDefault is not a good solution.

If you change your js to look like this it should work for you: var $txtLenLeft = $('#txt-length-left'); // lets cache this since it isn't changing $('#send-txt'). Keydown(function(e) { //take the event argument var Length = $(this).val(). Length; // lets use 'this' instead of looking up the element in the DOM var AmountLeft = maxLen - Length; $txtLenLeft.

Html(AmountLeft); if(Length >= maxLen && e. KeyCode! = 8){ // allow backspace e.preventDefault(); // cancel the default action of the event } }); You can see a working example here: http://jsfiddle.net/aP5sK/2.

Thanks, but the problem with this is you can't press the backspace or anything to change what you wrote – Bill Mar 13 at 21:03 @Phil: Answer and example has been changed to allow backspace :) – Martin Jespersen Mar 13 at 21:07 if you use preventDefault you can't go back using the arrow keys. – Hussein Mar 13 at 21:15.

Here's a solution using HTML5 data attribute to automatically bind to all needed textareas: $('textareadata-max-length'). Live('keypress', function(e) { if (String. FromCharCode(e.

CharCode || e. KeyCode). Match(/\S/) && $(this).val().

Length >= $(this). Attr('data-max-length')) { e.preventDefault(); } }).

I know this is a little late, but I just had to figure this out, too. I had to get it to work with UTF8 byte-lengths, and allow certain keypresses. Here's what I came up with: checkContent = function (event) { var allowedKeys = 8,46,35,36,37,38,39,40; var contentLength = lengthInUtf8Bytes(jQuery(event.

CurrentTarget).val()); var charLength = lengthInUtf8Bytes(String. FromCharCode(event. CharCode)); if (charLength + contentLength > 20) { if(jQuery.

InArray(event. KeyCode, allowedKeys) == -1) { event.preventDefault(); } } } countLength = function(event) { var len = lengthInUtf8Bytes(jQuery(event. CurrentTarget).val()); jQuery('#length').

Html(len); } lengthInUtf8Bytes = function(str) { var m = encodeURIComponent(str). Match(/%89ABab/g); return str. Length + (m?M.

Length : 0); } jQuery(function(){jQuery("#textarea"). Keypress(function(event){checkContent(event)}). Keyup(function(event){countLength(event)})}); You need to have a textarea with id #textarea and an element to display the current length with id #length.

The keypress event determines whether or not to allow the keypress. The keyup event counts the size of the data in the field after the keypress is allowed/prevented. This code works with the following keys: home, end, pagedown, pageup, backspace, delete, up, down, left and right.It doesn't deal with pasting from the clipboard.

Hope someone finds it useful!

Forgot to metion, the max length in this example is 20, as you can see in the if statement. – Andrew Plank Nov 28 at 8:52.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
