Manipulate DOM before it is shown to the user?
- by user246114
Hi,
I'm not too familiar with javascript, is there a way to manipulate the DOM before the page is displayed to the user?
I'm using GWT which makes you create the page elements via javascript. This is kind of convenient, but it appears that all the javascript code is executed after the page is first shown to the user. This has the effect of showing the page as a blank white screen, then all the UI elements popping onto screen. The effect is really apparent when switching between pages.
If I were using php or jsp, it looks like the page ui elements are already prerendered and the browser won't show a blank white screen before display.
So is there any hook in javascript where we can manipulate the DOM before the browser clears out the contents of the last page shown?
Thanks
