wait() or sleep() function in jquery?

setTimeout will execute some code after a delay of some period of time (measured in milliseconds). However, an important note: because of the nature of javascript, the rest of the code continues to run after the timer is setup:

$('#someid').addClass("load");

setTimeout(function(){
  $('#someid').addClass("done");
}, 2000);

// Any code here will execute immediately after the 'load' class is added to the element.

That'd be .delay().

If you are doing AJAX stuff tho, you really shouldn't just auto write "done" you should really wait for a response and see if it's actually done.


delay() will not do the job. The problem with delay() is it's part of the animation system, and only applies to animation queues.

What if you want to wait before executing something outside of animation??

Use this:

window.setTimeout(function(){
                 // do whatever you want to do     
                  }, 600);

What happens?: In this scenario it waits 600 miliseconds before executing the code specified within the curly braces.

This helped me a great deal once I figured it out and hope it will help you as well!

IMPORTANT NOTICE: 'window.setTimeout' happens asynchronously. Keep that in mind when writing your code!
