Before and after the string, left, and right Spaces
String.prototype.trim = function(){ return this.replace(/^s+|s+$/g,"")} 
String.prototype.ltrim = function(){ return this.replace(/^s+/g,"")} 
String.prototype.rtrim = function(){ return this.replace(/s+$/g,"")} 

Add a trim method to the String object.
You can use it like this in the future:
var s = " abc "; 
s = s.trim(); //S is a String and you can use the trim method just defined.
