Query Variable Function

Published in: JavaScript 

This function extracts a value from a url. Very useful for tracking codes. For example, you have a url http://your.url/?source=666999, and you need the source number to be placed into a variable. Use the code below.

  1. variable = getQueryVariable("what you want to extract");//e.g "source"

  3. function getQueryVariable(variable) {
  4.   var query = window.location.search.substring(1);
  5.   var vars = query.split("&");
  6.   for (var i=0;i<vars.length;i++) {
  7.     var pair = vars[i].split("=");
