Removing Whitespaces from Beginning of a String (Left Trim), using Javascript

Use the Javascript code below:

// Pass the string as argument (value) to the function below.
function LeftTrim( value ) 
 var re = /s*((S+s*)*)/;
 return value.replace(re, "$1");

If you have JQuery enabled in your code, then you can also use Jquery's trim() function to trim whitespaces from both ends of a string.

var trimmed_str = $.trim( str_with_whitespaces );
