DOMContentLoaded Redirect 1

The DOMContentLoaded event is fired when the document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading (the load event can be used to detect a fully-loaded page).

Note: Stylesheet loads block script execution, so if you have a <script> after a <link rel="stylesheet" ...>, the page will not finish parsing - and DOMContentLoaded will not fire - until the stylesheet is loaded.

General info

Yes (although specified as a simple event that isn't cancelable)

Bubbling for this event is supported by at least Gecko 1.9.2, Chrome 6, and Safari 4.

Cross-browser fallback

Internet Explorer 8 supports the readystatechange event, which can be used to detect that the DOM is ready. In earlier version of Internet Explorer, this state can be detected by regularily trying to execute document.documentElement.doScroll("left");, as this snippet will throw an error until the DOM is ready.

General-purpose JS libraries such as jQuery offer cross-browser methods to detect that the DOM is ready. There are also standalone scripts that offer this feature : contentloaded.js (supports only one listener) and jquery.documentReady.js (doesn't depend on jQuery, despite its name).
