It should be noted that the two points of onpagefinished, 1th, the official explanation:

Notify the host application A page has finished loading. This method was called only for main frame. When Onpagefinished () was called, the rendering picture could be updated yet. To get the notification for the new picture, use onNewPicture(WebView, Picture) .

That is, the program only thinks that the DOM loading is complete, and the picture being loaded is not within this range.

2nd, if in the JS file and dynamic to load another js,onpagefinished method will be all the JS loaded after all the call.
