Is there a way to trigger an event when the visibility of a div is changed?

Please, advice. It can be javascript or jquery as long as it is working.

thanks.

You must have code to change the div visibility. Fire an event after that with your conditions. This should solve the problem.

Or else you can set a timer interval to keep checking the visibility status of that element

var timer1 = setTimeout( "checkVisibilityStatus()", 2000); //after 2 seconds this method will be fired
var currentStatus = "none";
function checkVisibilityStatus()
{
    status = document.getElementById( "divId1" ).style.display;
    if ( status == "none" && currentStatus != status)
   {
      //do something if the div is now hidden
   }
   else if ( status == "block" && currentStatus != status)
   {
      //do something if the div is now visible
   }
   //if you want this method to fired again after two secs then
   clearTimeout( timer1 );
   timer1 = setTimeout( "checkVisibilityStatus()", 2000); //after 2 seconds this method will be fired
