View Full Version : an odd question

6 Sep 2011, 11:00 PM
I test in IE8 and EXTJS version is 4. I refreshed the IE8 some times and looked into the taskmgr(window), the memory of the IE8 has gone up about 400M. Could anybody help me to test this?

<frameset rows="80, *">
<frame id="top" src="top.html">
<frameset cols="200, *">
<frame id="left" src="left.html">
<frame id="main" src="main.html">
top.html main.html left.html are the same code

Ext.onReady(function() {
var p = Ext.create("Ext.panel.Panel", {
region: "center",
title: "AAA",
width: "100%",
height: "100%"
Ext.create("Ext.container.Viewport", {
renderTo: Ext.getBody(),
layout: "border",
items: [p]

Why are you using border layout when all you have is the center region? use fit.

That said, you are loading multiple copies of Ext JS in these frames. totally not usable and not suggested at all.

You're using frames??? What decade are we in?

Some shops rely on them. They have acceptable uses (in some rare cases). However, to load > 1 copy of Ext JS in a browser is just madness.

I'll take your word for it... I've yet to see an acceptable use for one, with the exception (maybe) of an iframe. But that's just my 2 cents B)

IMHO, the use is in legacy apps ;)

Just tried running it but couldn't see any obvious leaks. Tried inspecting it in sIEve? http://home.orange.nl/jsrosman/
