I want to use jQuery blockUI, but on their site they did not indicate what js to include, what to use css. Can someone please give me an example with full js and css to show how to use jQuery blockUI.
All you have to do is load the BlockUI script after enabling jQuery. CSS is not required to work.
See this script for the simplest demo: http://jsfiddle.net/ThiefMaster/4FhHK/
add this file after jQuery link
and then use the commands.
