Read Request Variables ...

So what?

This jQuery plugin gives the ability to read request parameters of the actual URL and makes them available for further use in your javascript files.

How do I use it?

This plugin works with jQuery 1.2.6+ (it may also work with older versions, but this is untested). So first of all you have to load the jQuery core (duh?) and this plugin as well. This may look something like this:

1
2

<script type="text/javascript" src="js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="js/jquery.url.min.js"></script>

After that you can use the $.url.param() function to get the values of the specific parameters.

For example we’ll take this URL: http://www.iana.org/domains/example/. Now we would like to know the value of the variable ‘name’ and call $.url.param("name") this returns a string, containing “john”. Inexistent or empty variables like $.url.param("inexistent") return an empty string “”.
