Hi All,
I've written an application for use offline (with Google Gears) on devices using IE Mobile. The devices are experiencing
memory leaks at such a rate that the device becomes unusable over time.
The problem page fetches entries from the local Gears database and renders a table of each entry with a link
in the last column of each row to open the entry ( the link is just onclick="open('myID')" ). When they've done with the entry they return to the table, which is RE-rendered. It's the repeated building of this table that appears to be the problem. Mainly the onclick events.
The table is generated
in essence like this:
var tmp="";
for (var i=0; i<100; i++){
tmp+="<tr><td>row "+i+"</td><td><a href=\"#\" id=\"LINK-"+i+"\""+
" onclick=\"afunction();return false;\">link</a></td></tr>";
}
document.getElementById('view').innerHTML = "<table>"+tmp+"</table>";
I've read up on common causes of
memory leaks and tried setting the onclick event for each link to "null" before re-rendering the table but it still seems to leak.
Anybody got any ideas?
In case it matters, the function being called from each link looks like this:
function afunction(){
document.getElementById('view').style.display="none";
}
Would that constitute a circular reference
in any way?
