# Prototype toQueryParams () Method

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>
