I have a tring with space.it is like this:

I want to take out the whitespace in left site and whitespace in right site .

This should do it:

[tt]string1 = string1.replace(/^\s*|\s*$/g,"");[/tt]

The bartender asks, "Are you aware that you have a steering wheel down your pants?"
The pirate replies, "Arrrrr! It's driving me nuts!

<script language="JavaScript" type="text/javascript">
String.prototype.trim = function() {

 // skip leading and trailing whitespace
 // and return everything in between
  var x=this;
  x=x.replace(/^\s*(.*)/, "$1");
  x=x.replace(/(.*?)\s*$/, "$1");
  return x;
}
</script>
