Add/Append query string if empty jquery/javascript

Question

How do I append a query string such as ?a=0 on document ready? It must first check if there is an existing query string. It should only append the query string if there isn't one there already. Otherwise, it should do nothing.

    window.location.href += window.location.search;

Try this:

$( document ).ready(function() {

    url = window.location;  //get current url
    if(url.indexOf("?a=") == -1){ //check for ?a= 
     document.location = url+"?a=0"; // redirect it
    }

});
