addDOMLoadEvent Revisited August 14th, 2007 I've gone back and reworked addDOMLoadEvent. I got rid of the global variables and reduced the size down to 563 bytes! For the new script and the demo pages, check out addDOMLoadEvent. Update [Aug. 19, 2007]: Now the script preserves any existing window.onload function, and also executes functions instantly when called after the page has already loaded. But now the compressed version is a hefty 617 bytes. Interested in web development? Subscribe to my newsletter!
