Prototype - parseQuery() Method

This method parses a URI-like query string and returns an object composed of parameter/value pairs. This method is similar to the toQueryParams();

This method is realy targeted at parsing query strings (hence the default value of "&" for the separator argument).

Syntax

string.parseQuery([separator = '&']);

Return Value

Returns an object having key value pairs.

Example

<html>
   <head>
      <title>Prototype examples</title>
      <script type = "text/javascript" src = "/javascript/prototype.js"></script>
      
      <script>
         function showResult() {
            var str = "http://www.example.com?section=blog&id=45#comments";
            var obj = str.parseQuery();
            alert ( "obj.section :  " + obj.section );
            alert ( "obj.id :  " + obj.id );
            
            var str = "tag=ruby%20on%20rails";
            var obj = str.parseQuery();
            alert ( "obj.tag:  " + obj.tag );

         }
      </script>
   </head>

      <br />
      <br />
