Some weeks ago I made a blog post, about IE7Pro userscripts, the Greasemonkey-like plugin for Internet Explorer 7.
I’m still deeply in love with userscripts for both IE7Pro and Greasemonkey, but what a waste of time for spending
hours on writing big userscripts with DOM javascripting to extend that “untouchable” website/webapplication.
This should be different! Why not use jQuery for IE7Pro userscripts.

The idea is to load first the jQuery script and then the userscript.
Unfortunately a javascript include script like this will not work:

//load jQuery
inc("jquery.js");

/* jsHandler.js */
function inc(filename)
{
  var body = document.getElementsByTagName('body').item(0);
  script = document.createElement('script');
  script.src = filename;
  script.type = 'text/javascript';
  body.appendChild(script)
}

However, it’s still very easy to let jQuery run for userscripts.
First download the latest jQuery lib.

Incase of IE7Pro:
Rename the downloaded jQuery script to: jquery.ieuser.js and place it
in the userscript folder. (path\IEPro\userscripts).

Open the jquery.ieuser.js file and add the following comment block on the top of javascript lib file:

// ==UserScript==
// @name           jQuery
// @namespace      jQuery
// @include        *
// ==/UserScript==

Now you can reload the jQuery file from the preferences – userscript screen in IE7Pro, and enable jQuery.
To test it, create a new userscript with the following jQuery code. As soon as it runs, you know
that you can use jQuery for every page.

// ==UserScript==
// @name           Test
// @namespace      Test
// @include        *
// @author Lee Boonstra
// ==/UserScript==

$(document).ready(function(){
  alert("jQuery in userscripts do work!");
});
