Stop JQuery refreshing DIV

Hi I've been using the suggestion made in Auto-refreshing div with jQuery - setTimeout or an开发者_如何转开发other method? to refresh a div. The div is refreshing a php script that is calculating lots of numbers in the background.

Does anyone know how I can stop the DIV refreshing once a the calculation in the php script have finished loading?

You can use a simple boolean or just an if statement.

finished = false;

function update()
{
   if ( finished )
      return;
   else
   {
      // continue calculating and call again
      window.setTimeout( update, 10000 );
   }   
}

Assuming your timer is called timer, you can call the following to cancel the timer that refreshes the div.

clearTimeout(timer);
