Place the test code below (if it survives the post) in an .html file
alongside a list of large images named "TestImage0.jpg",
"TestImage1.jpg",..."TestImage9.jpg". The page will leak memory (I used sIEve
for testing) on every click of the page. If the resize css is removed, the
page will not leak.
Test Code
<html>
<head>
<title>Memory Leak Testing</title>
<script type="text/javascript">
var count = 0;
window.onload =
function() {
AppendImage();
window.document.body.onclick = ReplaceImage;
}
var ReplaceImage = function() {
window.document.body.removeChild(document.getEleme ntById('MemTestObject' +
count));
count++;
if (count > 9) {
alert('No more images to load.');
} else {
AppendImage();
}
}
var AppendImage = function() {
var imageObject = document.createElement('img');
imageObject.id = 'MemTestObject' + count;
imageObject.className = 'MemTestObject';
imageObject.src = 'TestImage' + count + '.jpg';
window.document.body.appendChild(imageObject);
}
</script>
<style type="text/css">
.MemTestObject {
width: 140px;
height: 178px;
}
</style>
</head>
<body>
<h1>Memory Leak Testing</h1>
</body>
</html>
