I have a list of HTML controls and I need to bind a listener for the keyup event to each of these. Once that is triggered, some other actions should subsequently be kicked off after a time delay. I'm using setTimeout for that.

$(".TextBoxClass").each(function () {

  $(this).keyup(function () {

    alert("Id = " + $(this));   

    setTimeout(function () {

       alert("current Id = " + $(this))

    }, 50);



The first alert message shows the correct id of the control which triggers the keyup event. The second alert within the setTimeout says current id = [object][object].

How can I access the control within the setTimeout callback function?

<div id="controls">
    <input class="TextBoxClass" type="text" value="1" id="id-1">
    <input class="TextBoxClass" type="text" value="2" id="id-2">
    <input class="TextBoxClass" type="text" value="3" id="id-3">
    <input class="TextBoxClass" type="text" value="4" id="id-4">
    <input class="TextBoxClass" type="text" value="5" id="id-5">

$('#controls').on('keyup', '.TextBoxClass', function () {
  var $this = $(this);

    // alert("current value = " + $this.val()); 
    alert("current element id = " + $this.attr('id')); 
  }, 50);
