When document.readystate==complete is that the same when onload fires?
提问by GeorgeU
In internet explorer, when onreadystatechange is fired, and readystate switches to complete, is that the same time onload event triggers?Have all the requests completed by this time?
在Internet Explorer中，当onreadystatechange被触发，readystate切换到完成时，是不是同时触发了onload事件？此时所有的请求都完成了吗？

document.onreadystatechangeis typically more optimal than window.onloadas it fires before all external resources such as images are loaded. However, it's not well supported at the moment (but if you're only concerned with IE, then it's not a problem).
document.onreadystatechange通常比window.onload在加载所有外部资源（例如图像）之前触发时更优化。但是，目前它的支持并不好（但如果您只关心 IE，那么这不是问题）。

document.readyStateis a property and window.onloadis an event
document.readyState是一个属性并且window.onload是一个事件
