Um... hello? Is there anyone who has any idea how to implement a
touchmove event? Anyone, anywhere?
I have looked around the internet and asked on a few different forums,
and got zero response. Zero. Nothing. Not even people telling me to
"RTFM" or what's wrong with my question.
I've tried find
After much looking around on the subject, it is far from clear how I
can get my slider to respond to a touch event.
I have attempted to modify the YUI slider code as follows. What might
be going wrong?
Also, please note, I am a total JavaScript beginner. Not only is the
code cobbled together fro

Sorry I stepped away from this conversation for a bit. Work has a
nasty habit of getting in the way sometimes.
Thank you for replying and explaining the situation to me a little
more.
I can now see how touch events might diverge from mouse events in
certain
One other thing...
I've found differences between the way iPhone and Android handle
events. Mouse events on the iPhone are handled differently on Android,
so keep that in mind as well.

It *is* a little different. E.g. you won't have corresponding finger-
events for mouseover, mouseout, etc. The phone cannot quite detect
your finger hoverin
It probably will work, mouse and touch events won't happen
simultaneously.
As for touch, you can have multiple finger touches (think iPhone)
which can be interpreted differently than anything that can be done
with a mouse. Android doesn't (I believe) support "gestures" at this
point but may in th
John,
Thank you for the reply.
Hmm... seems a little odd to me that they went and made a whole
different set of events for using fingers on a touch screen when they
are duplicates of what I do with a mouse. There's nothing about
touching with a finger which, as far as I can see, is operationally
The reason they don't work on the Android browser (or webkit for that
matter) is that they are using mouse events. If you want to use that
code on the Android you have to use touch events instead. Try reading
up on the following:
touchstart - finger touches the screen
touchmove - finger is moving

No... no it's not. Let's not get into broad statements about what my
environment is like or how I handle it. Linux is fine, it's me who has
different abilities, so please leave it for me to decide what I can

In a word: YES!
Implementations of JavaScript vary across all the major platforms, you
have to be very careful about testing, test and more testing each time
you make a change to any code on a web page. The worst offenders are
IE6 and IE7. Safari has plenty of quirks and as the iPhone is a

Oh certainly, but as I said, it works in the emulator. So currently I
don't think my problem is due to heavy javascript usage. I don't want
to steal the thread from ebisudave, but as an example of the kind I
have trouble with, take a look at the top chart here (animated jquery
sparkline example):
You can easily test your device's browser JavaScript capabilities by
calling up a Google Map API (v3 is best on mobile) application. Here's
one you can try:

If this map works, you have JavaScript enabled.

"What Zip Code?"
I think a lot of developers, especially ones from the web world,
forget that these mobile devices are like desktop computers of the
mid-90's in power and speed. Trying to get a complex JavaScript
application to run on the phone is probably going to be disappointing.
Just because it runs on FF with

JQuery for some animation on a 1 sec timer which also fails in the
Android browser. The only thing I can imagine is that we run into some
kind of JavaScript speed limitation, exhausted javascript message pump
