background switch page load

I've seen a lot of different background switching based upon link classes, however I just want a s开发者_C百科imple background switcher on any page load (no cookies) and not link dependent.

is there a simple method for this? jquery?

Are looking for javascript timers?

Example:

setInterval("switchBackground()", 1000);

function switchBackground( )
{
   $("body").css("backgroundImage", "xxx");
}

I hope this help!

Edit:

To generate random background at start:

$(document).ready(function() {
   //This will be random from bg1.jpg to bg10.jpg
   $("body").css("backgroundImage", "/images/bg"+GenerateNumber(10)+".jpg");

   //1 to max
   function GenerateNumber(max) {
      return Math.floor(Math.random()*max) + 1;
   }
});

The code for a random background image provided by Mouhannad didn't work for me, I had to make a few small edits in order for it to function:

$(document).ready(function() {
   //This will be random from bg1.jpg to bg10.jpg
   $("body").css("background-image", "url(/images/bg"+GenerateNumber(10)+".jpg)");

   //1 to max
   function GenerateNumber(max) {
      return Math.floor(Math.random()*max) + 1;
   }
});

I needed to change the "backgroundImage" declaration to "background-image" and also added "url()" to the image path. JavaScript uses the CamelCase notation for CSS properties, jQuery does not.
