trim() is not working in Internet Explorer(it's working properly in Chrome and Firefox). However I need to trim the value to prevent empty spaces.

I don't think JavaScript provides trim() does it? Some browsers may implement it, and various libraries implement it.

You can add your own, something like this:

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

If this turns out to be an IE bug, you can always implement your own workaround using RegEx in JavaScript like this left trim function sample - the sample can be expanded to trim both left and right sides. This Regex should work in all browsers.
