Ext 2.0 - beta1 for JSVM2

[wanchanghua]

I very like Ext, It's a great job!
but, Ext is so intricate for code management.

I hope JSVM2 can give Ext a hand. :)
For example :


<script src="jsvm2/jsre.js"></script>
<script>

$import("Ext.EventManager");

Ext.EventManager.on(window, 'load', function(){
//TODO ...
});
</script>

question 1: what are the advantages of JSVM2 over others like, say, Rhino? (and what's the difference?) :-/

question 2: how will JSVM2 help to simplify Ext development? :-/

question 3: is there anywhere else where i can download / see a demo? :-/ the link you provided above stalls at 1.1mb, the JSVM2 sourceforge site hasn't been updated since december 18th 2006, and all the demo sites i've googled lead to nowhere... :s

i know something about JSVM (BSD License), it's well designed to modularize prototype-based javascript programming, and it will automatically manage code dependence so you even no need to care about intricate code dependency :D

in a nutshell, JSVM is a good example in code organization for reference. We all like Ext and hope Ext will be better and better. ;)

thanks for the info. :)

do you have any links where i could take a look at some demos?

[seasky7]

this is a demo url:

http://demo.jsvm.org/ext2/ext-2.0-beta1-jsvm2/examples/

you can compare with EXT examples

http://extjs.com/deploy/dev/examples/


we can open the same example from Ext and JSVM

The first, clear all IE's caches.
the JSVM url :
http://demo.jsvm.org/ext2/ext-2.0-beta1-jsvm2/examples/desktop/desktop.html

use HTTPWatch ，get IE load data：
1、total load time：6.202S；
2、main code file size ：149538；

ok,we open the EXT desktop example：
URL:http://extjs.com/deploy/dev/examples/desktop/desktop.html
use HTTPWatch ，get IE load data：
1、total load time：17.101S；
2、main code file size ：502651；

compare main code file size is JSVM=149538 < EXT = 502651 ---- （1：3）

The result is impressive.
And I think it should be more effective when we using iframe or frameset based application.

helloniko is right. seasky made a mistake. JSVM2 example is compressed with gzip.
JSVM2 can help you load javascript code on demand.

The attatchment is code organization chart.

@wanchanghua: very interesting... :D
will fiddle with it when i get some time.

thanks to the rest for replying =)

p.s the download link's working now.
