Before somebody else gets all nit-picky/pedantic, it's worth pointing out there's a JSON object in Firefox as of at least 3, but I think it's only available for extensions to use (http://developer.mozilla.org/en/NsIJSON). In other words, useless to web developers.

Technically, it's possible if your visitors have signed.applets.codebase_principal_support set to true and your code asks for and recieves UniversalXPConnect, but that's dangerous and unrealistic.

According to bugzilla, Firefox 3.1 and JavaScript 1.9 will include this....So i guess its a game on who releases first? Comparing betas to betas is quite a gray area I would think

You need to develop something new!!!

JackyMao — Wed, 10 Sep 2008 05:12:02 GMT

As I looked through all these FEATURES, I can't say this is what I want!

You IE team just always make things too TECHNIC, you need to add something new, something really exiting people. so that people can turn to IE & say "you see, the new IE is really exiting." you need to make people surprise & admire, but not just say by your self,"Does this sound interesting?" No!

Let me tell you what can make people surprise, at least in China.

1. You can make an website, that can support IE very good, but do not support other browser so well. Put MUCH MORE interesting pages in this website. & Show to people how IE is interesting. Try to give people a surprise! & admire! Do not just do as your TECHNIC brain think!

2. Develop something that can make people develop their own page just in IE, they can rebuild whatever interesting page they like, & use for their own site. If possible, make the ie can connect to a database, sql server or mysql or something.

------------------

That's all for now, just make IE simple, & attactive. No TECHNIC.

I am in expectation that IE can do something wonderful, so I post here.

Is IE 8 going to support prototyping on DOM objects like elements? That would help us pull off interim solutions to some of IE's other DOM shortcomings.

Any word if the enhancements include (or will include) support for the RFC 4329 MIME types (i.e., |application/javascript| and |application/ecmascript|)? (On that topic, it would also be nice if the correct MIME type for XSLT was supported (i.e., application/xml).)

I still live in hope that they'll solve the design flaw of not being able to append to the DOM before the page reaches complete state, like all other browsers in existence allow you to do, but IE gives you "Internet Operation Aborted Error". Yes I know there was another blog post about this, but it's clear the IE team still think this is not their error. They think it shouldn't be allowed, and that downgrading it from the equivalent of a BSOD for a browser, to just an exception that can be handled, is the answer. No it's not. It's still not doing the job we want it to.

So I'll still need a logic branch to handle IE needing to wait before I can dynamically create elements, whereas the else (being ALL other browsers) can go ahead and add without fear.

This is the most important problem IE has for me, and even IE8 isn't going to solve it.

I think that these are very good improvements. I think that the greatest benefit will be for developers of Internet sites.

Olivier — Wed, 10 Sep 2008 12:35:13 GMT

@JackyMao : your suggestions are very wrong :-/

We want that ALL browsers works the same on EVERY websites.

So why suggesting to make a website which only works with IE ? That's not the way to get new users.

The differences between browsers should only be the user interface, the speed, customizations,... stuff like that, but the rendering should be exactly the same.

as said, js would become more important in the future internet application. I do think so.

ie should provide more convenient and rich js error control for developers.

@JackieMao

If you want to see something new and useful check out Firefox3.1 alpha2

Support included for the HTML5 <audio> and <video> tags. These should have been around for a long time.

One day maybe, people will be able to go over to watch the channel 9 video in their browser without having to install Silverlight.

(to be fair you can download it)

Thank You!

Thanks for making these important changes. Hopefully IE continues to gain in performance and by making it much easier for us as developers its a good change to see.

Is it just me, or did javascript performance see a huge speed boost in beta 2 over beta 1?

The profiler is a killer feature that I've been wanting for a long time. Some areas need polishing - the "Line Number" does not appear to be accurate (always displays "1" in my test), and it's pretty important to be able to uniquely identify the functions being listed (i.e. by their object scope). Still, this is awesome stuff.

Great job IE8 team, keep the good stuff coming!!!

@Olivier Thanks for your reminding, I just mean IE need some new way to get new user. NEW way. Not just walk away in this single way.

@Mike Thanks, I am using Firefox also, competition can make IE & Firefox move on.

re: What’s New in JScript for IE8 Beta 2

Olivier — Thu, 11 Sep 2008 13:58:38 GMT

@JackyMao : yes, I agree with you that new ways to get new users are needed.

What I meant was to fix problems first, then of course, if they have time they can create new interesting features (like they already did with the Accelerator and Webslice).

PS: I'm a web developer, that's why I think fixing rendering bugs is much more important than anything else :)

Are there still fixes planned? Because in IE 8 Standards mode, when using CSS pseudoframes (say, a fixed size, absolutely positioned, scroll:auto div), if a page element has an even handler (mychild.attachEvent("onclick",myfunction} for example) which triggers some DOM modification (innerHTML and appendChild work) then the pseudoframe scrolls back to top (focus doesn't change).

The listener element and modified element don't have to be children of the pseudoframe to trigger the 'scroll to top' bug.

I've successfully triggered the bug with key (-press,-down,etc.) and mouse (-over,etc.) listeners.

Basic page exhibiting the bug: http://www.moneyshop.fr/testscroll.html

Same function used with W3C event structure, no problem in Firefox/Opera/etc.

To use, scroll the pseudoframe a bit, then hover the top paragraph: instant reset.

Any idea on a bugfix? Current workaround is to fallback to IE7 mode - which I don't want (other IE 8 bugfixes allow me to forgo a lot of compatibility CSS code).

Mitch 74 — Tue, 16 Sep 2008 12:10:18 GMT

erratum: I meant: 'overflow:scroll' of course (or, as is the case of the example, overflow-y:scroll).

addendum: using CSS DOM modifications (with :hover:before for example) triggers the bug too, as well as the Netscape legacy event model; as such, I'd say any DOM modification entails a reset of all pseudoframes scrolls on the page.

Test case has been updated.

How about significantly better garbage collection, and actually cleaning up when the WebBrowser control is destroyed? I realise that this refers to the OCX rather than IE8 itself, however at the moment the WebBrowser control leaks enormous amounts of memory, even when nothing is loaded into the control. This is trivially reproducible in both managed and unmanaged code, in single and multi-threaded applications. It is even worse with pages that use JavaScript, somewhere along the line cleanup is simply not being done, as almost all allocated memory is leaked. I have reproduced this, but there seems to be no avenue to actually report the issue to the IE8 Beta team. I eventually reported it to the Visual Studio .NET framework team, who closed the bug, as it is not directly related (which is fair enough): https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=362973&wa=wsignin1.0

I sincerely hope that something is done about this, as it is a show-stopper when it comes to using the WebBrowser control.
