Question

I have a text input and a textarea and I’m passing the value from the input to the textarea. I am trying to do, when you type something in the input and you stop, after 2 seconds show the values to the textarea.

In this example the textarea gets the input’s value instantly:

So i want, when you type and stop, after 2 seconds give the value.

How can I achieve this? I tried to use setTimeout but when the 2 seconds pass, then it keeps getting the value instantly. So basically it works for the first 2 seconds.

You have to reset the timer everytime the user presses the key again:

jQuery(function($){

   function changeFn(){
      alert('Changed');
   } 


   var timer;

   $("#string").bind("keyup", function(){
      clearTimeout(timer);
      timer = setTimeout(changeFn, 2000)
   });

});
