I have created a slider using Javascript and html tables that
generally works very well.
As you move the "knob" to the right, a numeric value in an adjactent
<INPUT type="text"> tag increases. As you move the knob to the left,
the numeric value decreases... just as it should. It works very smooth
and seamlessly. Very responsive to the mouse's movement.
Now, I would like to make this INPUT tag have type="hidden". But when
I make that simple, one-word change and try it out, the resulting
slider is VERY sluggish and unresponsive. The slider doesn't even come
close to keeping up with the mouse.
Does anyone know why this happens? I can't come up with any
explanation.
Is there a known work-around?
Thanks

Probably because of the use of a bad browser with poor javascript
implementation. M$ IE by any chance?

That is an implementation-specific issue. Why does it have to be an
input hidden value that you change?
Here is a simple work-around that should work for you on all JS
capabable browsers...
Try changing a global variable, instead of the hidden value. If you
need it for form submittal, simply define the onSubmit method of the
form, and assign the variable to the hidden input field, and away you go :)

That is silly.
I use Mozilla 1.4.1 and don't have that problem, but I couldn't check your
code of course.
If you want me to, post it.
Good luck solving it.
If you found a workaround or solution, let us know.
Good luck!

For the OP to post and say "Mozilla 1.5 displays this behavior" is
"silly"??? Quite contrary. For you to post and say that its silly, when
you have not tested what the OP is seeing, is beyond silly - its
downright ignorant.

Relax man, you are missing my intention/point, and start calling me names
that would better describe yourself if you read this thread carefully.
This is the situation:
When Saqib Ali wrote he was having slow Javascript when updating hidden
fields, I checked that on my own browser (Mozilla 1.4.1) by making a small
program that does just that.
I didn't notice any slow performance.
So I asked if Saqib Ali was using a broken browser, like IE which is known
for it strange non-standard Javascript behaviour.
He wrote he was using Mozilla 1.5.
So I responded that was silly.
Silly that I was using Mozilla too (and a close version).
Not the fact that he uses Mozilla, which I do too.

I have a large form that is generated dynamically in a jsp using xml / xslt. So, to

to "display:", or hidden with "display:none". This gives the illusion that the person

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
