IE 8 javascript problem

Question

Hi following code throws the "Object doesn't support this property or method" error in IE.. var value = $input.val().replace(/ /g, '').trim(); It is part of form validation, in every other browser is it working well, but in IE it doesnt..please help

`trim()` was introduced with ECMAScript 5 and IE8 does not support this. Actually it does not seem you need `trime` anyway, because you already remove every space by calling `replace(/ /g, '')`. If you are worried about the other whitespace characters, you could use `\s`: `$input.val().replace(/\s+/g, '')`. — Felix Kling, Apr 11 '11 at 22:10

As was commented on your question, IE8 doesn't support trim(). jQuery includes the trim() function, so I'd use that:

var value = jQuery.trim($input.val().replace(/ /g, ''));

From Ben Rowe: 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, ''); 
  }
}
