The application I am working on has several very complex pages, which take some time to render in the browers. I used the link above to create a ‘loading‘ gif (with great thanks to the authors and contributors). Set up a div to contain the image and ‘Loading, please wait …‘ text, with z-index set to -1. Added dojo.OnLoad() to hide the loading div and display the main div.

The effect of these changes is to prevent display of the page content until dojo had fully rendered it.

A side effect is that the page seems to load and display much more quickly. I suspect this is because the browser doesn’t have to display the page as it is being rendered.
