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

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

Syntax:

string.toQueryParams ([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.toQueryParams ();

  alert ( "obj.section :  " + obj.section );
  alert ( "obj.id :  " + obj.id );

  var str = "tag=ruby%20on%20rails";
  var obj = str.toQueryParams ();
  alert ( "obj.tag:  " + obj.tag );

}

</script>
</head>

<body>

  <p>Click the button to see the result.</p>
  <br />
  <br />
  <input type="button" value="Result" onclick="showResult();"/>

</body>
</html>

To understand it in better way you can Try it yourself.
