Description
jQuery Version: 1.2.3 Internet Explorer Version: 6 or 7
In the following example sIEve will report two leaks for every time leak() is called only when the page is inside a frame. If this html is served itself as the main page it will not report a leak BUT if it's served inside the below frameset these two leaks are reported each time the leak() function is called: <div>div<div></div></div>
It does not have anything to do with the append function as the noleak function (which doens't leak) also uses append. It happens anytime you create dom objects using $("..."). In my project we are dynamically creating a large table and each node in the table is reported as leaking when leaving the page. If I remove the frameset these nodes do not leak.
<frameset rows="*" framespacing="0" border="false" frameborder="0">
<frame src="frame.htm" frameborder="0">
</frameset>
<!-- frame.htm source --> <html>
<script language="javascript" src="jquery-1.2.3.min.js"></script> <script>
$(document).ready(function(){ });
function leak(){
$("#mydiv").append(":leak ");
}
function noleak(){
var text = document.createTextNode(':noleak '); $("#mydiv").append(text);
}
</script> <body >
<div id="mydiv">should be appended here</div><br/> <a href="#" onclick="leak();">leak</a><br/> <a href="#" onclick="noleak();">noleak</a><br/>
</body>
</html>

I don't see an increase in memory with 1.4.2 and IE8 so I'll close this ticket.
