jQuery + Greasemonkey = ♥

by on Feb.15, 2008, under General

I have come to love jQuery – It is incredibly slick to automate basic tasks.  The winning combination is being able to dynamically load jQuery with a browser plugin called greasemonkey (wikipedia entry). 

I got sick of always having to log-in to a specific site and click through links to get to what I wanted, so here is a sample of a userscript that logs me in and manipulates things the way I want them to.  I have written some other ones to do extra calculations on top of pages.  Its a handy combination.

Of course to round out the development of these scripts don’t forget to use FireBug!!

// ==UserScript==
// @name           Crestock
// @namespace      net.colinharrington
// @include
// @include
// ==/UserScript==

var my_username = 'username';  //fill this in yourself...
var my_password = 'password';  //again use your own...
// Add jQuery
var GM_JQ = document.createElement('script');
GM_JQ.src = '';
GM_JQ.type = 'text/javascript';

// Check if jQuery's loaded
function GM_wait() {
    if(typeof unsafeWindow.jQuery == 'undefined') { window.setTimeout(GM_wait,100); }
else { $ = unsafeWindow.jQuery; letsJQuery(); }

// All your GM code must be inside this function
function letsJQuery() {    

I may get around to submitting some of these to the public repository over at
