FAQ Topic - How do I trim whitespace -
trim/trimRight/trimLeft
-----------------------------------------------------------------------

Using Regular Expressions (JavaScript 1.2/JScript 3+) :

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