This brilliant method belongs to Joe Zim’s JavaScript Blog.

Here is the function.

    var parseQueryString = function( queryString ) {
        var params = {}, queries, temp, i, l;
        // Split into key/value pairs
        queries = queryString.split("&");
        // Convert the array of strings into an object
        for ( i = 0, l = queries.length; i < l; i++ ) {
            temp = queries[i].split('=');
            params[temp[0]] = temp[1];
        return params;

Using the function.

   function Test() {
        var qstring = "apple=7sf&orange=242&bananna=47614&cherry=8139";
        var myNewArray = parseQueryString(qstring);

As you can see, you now have an array of all of your query strings!
