URL: http://css-tricks.com/snippets/javascript/get-url-variables/

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

getQueryVariable(”id”) – would return “1″. Calling getQueryVariable(”image”) – would return “awesome.jpg”.

  1. function getQueryVariable(variable)
  2. {
  3. var query = window.location.search.substring(1);
  4. var vars = query.split("&");
  5. for (var i=0;i<vars.length;i++) {
  6. var pair = vars[i].split("=");
  7. if(pair[0] == variable){return pair[1];}
  8. }
  9. return(false);
  10. }
