JavaScript Event – Resize

This code was written based on a template by John Resig. The original can be found at John Resig’s addEvent function website.

The code, and the template, are referred to in Webmonkey’s JavaScript Events reference page. In this example, the onResize event fires when the page is resized. The event can also be attached to a fame to determine when it has resized.

The Code

<html>

<head>

<script>

// addEvent function by John Resig:

// http://ejohn.org/projects/flexible-javascript-events/

function addEvent( obj, type, fn ) {

  if ( obj.attachEvent ) {

    obj['e'+type+fn] = fn;

    obj[type+fn] = function(){obj['e'+type+fn]( window.event );}

    obj.attachEvent( 'on'+type, obj[type+fn] );

  } else

    obj.addEventListener( type, fn, false );

}

</script>

</head>

<body>



<!-- HTML for example event goes here -->



<script>

// Script for example event goes here

addEvent(window, 'resize', function(event) {

	alert('The page has been resized');

});

</script>

</body>

</html>
