I'm looking for a tool which would lock my web page while it's loading.
For example, let's say I have a left menu with some links. Whenever I click on one of them, a div (or anything else like an image and some text saying "loading...") pops up in the middle of the screen and the rest the page becomes unclickable with a soft gray background over the whole website.
In case you don't get what I mean, here's an example: http://www.swsoft.com/en/products/plesk/demo/
The Plesk Control Panel does exactly what I want. Does anybody have an idea how it's done please ?
Thanks in advance !
