jQuery event to trigger action when a div is made visible

Question

I\'m using jQuery in my site and I would like to trigger certain actions when a certain div is made visible.

Is it possible to attach some sort of \"isvisible\" even

Answer 1

Just bind a trigger with the selector and put the code into the trigger event:

jQuery(function() {
  jQuery("#contentDiv:hidden").show().trigger('show');

  jQuery('#contentDiv').on('show', function() {
    console.log('#contentDiv is now visible');
    // your code here
  });
});
