JavaScript method to get url query parameters

This article illustrates how JavaScript gets url query parameters. Share to everybody for everybody reference. Specific implementation methods are as follows:

function getQueryVariable(variable)
{
  var query = window.location.search.substring(1);
  var vars = query.split("&");
  for (var i=0;i<vars.length;i++) {
    var pair = vars[i].split("=");
    if(pair[0] == variable){return pair[1];}
  }
  return(false);
}

Usage:

Example URL:
http://www.example.com/index.php?id=1 & image=awesome.jpg

Calling getQueryVariable("id") - would return "1".
Calling getQueryVariable("image") - would return "awesome.jpg".
