JavaScript Function to Trim White Space (RTRIM)

Like the LTRIM previously posted, this function trims white space, but from the right of the text.

/*

	RTrim - Trims whitespace from right of a string

*/

function RTrim(str)

{

	var whitespace = new String(" \t\n\r");



	var s = new String(str);



	if (whitespace.indexOf(s.charAt(s.length-1)) != -1) 

	{

		var i = s.length - 1;       // Get length of string

		while (i >= 0 && whitespace.indexOf(s.charAt(i)) != -1)

		i--;

		s = s.substring(0, i+1);

	}



	return s;

}
