Retrieve URL Query String with JQuery

Posted on: March 13, 2012 — 13 Comments

Here’s a quick and easy way to get a query string from your URL using jquery. Suppose you have the following URL: www.myurl.com?page=mypage. Use the code below to retrieve page=mypage. Of course this can be any name/value pair…

<script type="text/javascript">
  function getQuerystring(key, default_){
    if (default_==null) default_="";
    key = key.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regex = new RegExp("[\\?&]"+key+"=([^&#]*)");
    var qs = regex.exec(window.location.href);
    if(qs == null)
      return default_;
   else
     return qs[1];
 }	
 var urlString = getQuerystring('page');
 
  $(document).ready(function(){
    if ( urlString == 'mypage' ) {  
      //Do something with jquery here
    }
  });
</script>
