Using
addEventListener(or IE'sattachEvent) doesn't change the contents of theonclickattribute - they're independent.There shouldn't be any need to time delay the
loaded()function - just do:window.addEventListener('load', loaded, false);If you're assuming W3C DOM event handling (which your
loadhandler does) then there's no need for the IE-onyattachEvent()call
加载中,请稍侯......
