JQuery Code

JQuery Code is given below, In this code the JQuery .delay() method is used which will delay the execution of function in the queue.

The .queue() method is also used which shows the queue of functions to be executed on the selected html element.

While the .dequeue() method removes the next function from the queue, and then execute it again. .dequeue() method is used to allow the sequence to continue.

In this example whenever button is clicked, it's text is changed to 'Please Wait' and then after a delay of 2 seconds, text is changed again.

So on each click the function execution is delayed by 2 seconds.


<script>
$(document).ready(function(){ 
 $("button").click(function(){
  $(this).text('Please Wait');
  $(this).delay(2000).queue(function() { 
  $(this).text('2 Seconds Completed');
  $(this).dequeue();       
  });
 });
});
</script>
