The window.onload event is called once the HTML page has completely loaded and initialized. When the browser calls window.onload, the browser is giving a script the chance to initialize itself with a complete HTML page. For scripters, this method is very interesting, and if there are two toolkits using window.onload, more likely than not one will overwrite the other.
