The jQuery library is a wonderful project and great things can be thought of! I dont use it too much but once in a while I code something I feel is nice to have easy access to. And thats here..
Automatically Generate & Display a QR code to this page (like the one on the bottom, but with jQuery instead of php)
The code:
$(document).ready(function() {
$('#thispage').html('<img src="http://chart.apis.google.com/chart?cht=qr&chs=120x120&chl='+window.location.href+'">');
});
The div
<div id="thispage" style="border-width: .1em; border-style: dotted; width:130; text-align: center; background-color: #FFFFFF;""></div>
