.trim() in JavaScript not working in IE

Add the following code to add trim functionality to the string.

if(typeof String.prototype.trim !== 'function') {  String.prototype.trim = function() {    return this.replace(/^\s+|\s+$/g, '');   }}

It looks like that function isn't implemented in IE. If you're using jQuery, you could use $.trim() instead (http://api.jquery.com/jQuery.trim/).

jQuery:

$.trim( $("#mycomment").val() );

Someone uses $("#mycomment").val().trim(); but this will not work on IE.
