How to fix this window.open memory leak?
- by DotnetShadow
Hi there,
I was recently looking at this memory leak tool sIEve: http://home.orange.nl/jsrosman/
So I decided to test out the tool by creating a main page that will open up a popup window.
I started by creating 3 pages: index.html, page1.html and page2.html, the index.html page will open a child window (popup) linking to page1.html. Page1 will have a anchor tag that links to page2.html, while page2 will have a link back to page1.html
PROBLEM
So in the tool I entered the index.html page, popup window opened to page1.html, I then clicked the page2 link, no leaks detected yet.
While I'm on page2 I click the link back to page1, and that's where the tool claims there is a link. The leak seems to be happening on the index.html page and I have no idea as to why it would be doing that. Even more concerning is that I can see elements that the tool detects that aren't even on my page.
Does anyone have any experience with this tool or know if this really is a memory leak?
Any samples of showing how to achieve what I'm doing without memory leaks?
INDEX.HTML
<script type="text/javascript">
MYLEAK = function() {
var childWindow = null;
function showWindow() {
childWindow = window.open("page1.html", "myWindow");
return false;
}
return {
init: function() {
$("#window-link").bind("click", showWindow);
}
}
}();
</script>
</head>
<body>
<a id="window-link" href="#" on>Open Window</a>
<script type="text/javascript">
$(document).ready(function() {
MYLEAK.init();
});
</script>
</body>
</html>
PAGE1.HTML
<html>
<body>
<h1>Page 1</h1>
<a href="page2.html">Page2</a>
</body>
</html>
PAGE2.HTML
<html>
<body>
<h1>Page 2</h1>
<a href="page1.html">Page1</a>
</body>
</html>
Appreciate your efforts.
