Javascript detect a selection of browser AutoComplete value

I have a text field with an onkeyup event. But this event is not fired when I select a browser autoComplete value. I have added an onclick event, but it doesn't work.

I have tested many solutions posted on stackoverflow for catching the browse autocoComplete selection, but nothing has resolved this problem.

Try this simple example to see the issue (reproduced on Firefox 3.6, Chrome 10.0 and IE8):

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
    <title>Test</title>
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.5.1.min.js"></script>
    <script type="text/javascript">
    //<![CDATA[
        function onkeyupInput(){
            $('#divResult').text($('#myInput').val());
        }
    //]]>
    </script>
</head>
<body>
    <form name="myForm" action="#">
        Tape a value and send it. Then select this value with your browser AutoComplete value :<br />
        <input id="myInput" name="myInput" type="text" onkeyup="onkeyupInput();" onclick="onkeyupInput();" value="" />
        <input type="submit" />
    </form>
    Result of onkeypress and onclick :
    <div id="divResult"></div>
    <br />
    <b>The issue : Result of onkeypress and onclick is not update when an autocomplete value of a browser is selected.</b>
</body>
</html>

Thanks!

Newer browsers support the oninput event:

$(function () {
  $('#myInput').on("input",function() {
    $('#divResult').text($(this).val());
  });
});

<input id="myInput" name="myInput" type="text" value="" />

If you need to support older browsers, try 

var tId = "";
function monitor() {
 $('#divResult').text($('#myInput').val());
}

$(function () {
  $('#myInput')
  .focus(function() {
      tId=setInterval(monitor,100);
  })
  .blur(function() {
      clearInterval(tId);
  });
});
