Beautiful. Thanks for sharing.
In tinydomready.js it has to be DOMContentLoaded
instead of DocumentContentLoaded
.
Yes I believe that's a mistake @dciccale, in line 7 of tinydomready.js DocumentContentLoaded
should be DOMContentLoaded
. In the last revision this was changed for some reason.
Perfect! Thanks!
window.onload
is not the same as DOMContentLoaded
https://developer.mozilla.org/en-US/docs/Web/Events/DOMContentLoaded
Great work, i also see this from https://stackoverflow.com/questions/799981/document-ready-equivalent-without-jquery by Peter Mortensen and Timo Huovinen
function start(f){ /in/.test(document.readyState)?setTimeout(start,5,f) : f()}
usage
start(function() {alert("I'm ready"); });

Window onload is not the same as dom ready aka DocumentContentLoaded here.
In IE8 and below this will fire function where all resources (such as images and so) is loaded.
