Hi All,
I was looing for some kind of information how event handling would be done in a mobile browser..
i would be greatful if i could get some info on how i can implement the complete event handling module from capturing of events to handling(invoking scripts and as such... )...

(PS :@ KOR
As per ur suggestion Kor , i started a new thread

so that i cud get some more help... please keep me updated with ur thoughts)

You must first tell us what kind of browser u will use. Compatible NS, compatible Mozilla? Compatible IE... And which version NS4, NS7, IE4, IE 6, ....

Second you must make clear what you understand by "handling events"

I am really sorry for keeping it abstract...

I am currently referring KHTML which is used in webcore... (apple's browser... )

i would actually put across a sample case ..

<input type = "button" name="b" value="Search" Onclick="doSomething()">

on coming across something like this i know that firts step would be registering a handler and then we will have to probably invoke the scripts whenthe onclick actually happens.. this is the skeleton flow i know .. i would like u to tell me how can i go about the implemenatation of the same and in the first place if i am right about the above explanation... ..

please lemme know on how i can go about the implementation of the same
..
i hope i am clear...

I am not sure if i have put across my problem clearly... i would like to know if any more details are required so that i can get some lead to get started..

It varies widely by device and browser.

I can tell you that that specific example will work in Pocket IE, but that's about the limit of its complexity - it doesn't support DOM handlers, only inline handlers.

Mobile Opera 8 however is almost on a par with its desktop cousin, however you still have a limited range of events, because the devices just can't generate many of them - you'll get click events, focus events if a device has a d-pad, and the usual programattic events like the submit event of forms and the onreadystatechange of an xmlhttp request.

Minimo sucks and blows - I wouldn't waste time with it.

But really - the bottom line here has to be one of practicality - if you're developing for a mobile platform, you need a test device; there's no way you'll be able to do a good job just by asking people to check it every now and then.

So - do you have such a device? What is it running? Is that your target audience?

Thanx for the response........
currently my device is Pocket PC......but the whole idea is to have platform independent browser may be catering to a whole range.As of now i have started on pocket PC.
can i get some information on how i can use the DOM to achieve the whole of event handling.Details on how one would invoke DOM and more on the flow of the control for event hamdling using DOM.

Okay well as it stands now, what you want is a pipe-dream - you're not gonna be able to make an app that works on all mobile browsers, you will have to code-fork for each specific one you want to support.

So - if Pocket IE is your first audience, DOM scripting is not gonna help you - it doesn't properly support it, it generally only supports inline handlers. So the first thing I suggest is that you set up a test page with a few inline handlers, and see which ones are working.
