How to implement a background execution in JavaScript?

For example, I would like to download part of data from the server when I click one button, and downloading other parts in background. How to implement this?

If you are targetting HTML5 compatible browsers take a look at Web Workers :

You have only one execution thread, so you will have to play with setInterval() and clearInterval() and execute your code based on timers :

var iv= setInterval(function(){ alert("Running now!"); }, 3000);

Clear the periodic function with :

clearInterval(iv);
