The Trim Function in JavaScript

The Trim Function in JavaScript

JavaScript doesn’t have a trim to strip the spaces around strings. This little bit of code uses regular expressions to strip the spaces around given input.

function trim(input){  var lre = /^s*/;  var rre = /s*$/;  input = input.replace(lre, "");  input = input.replace(rre, "");  return input;}
