How to change form elements dynamically?

Dave Straley · 03-13-2000 03:06 PM

Hi,

Can anyone direct me to sample code or a tutorial or discussion as to how
I can change a form's elements dynamically, without hitting the server?
I've seen this on a Microsoft search site, where the User chooses HOW they
want to search via Radio buttons, and based on HOW they chose, the Web page
instantly refreshes (without hitting the server) so as to show a Text input
box or a Select list, etc. I assume this is done in DHTML, but I can't figure
out how to pull it off.

Any leads would be appreciated!
Take care,
Dave Straley

You can do this with the CreateElement function. See here for details and
example:

Steve,

Thanks a ton for that link. I checked it out and it's impressive. However,
it's not quite what I've seen in action on the MS site. For example, the
createElement() function says that it can't create Select lists. However,
on the MS site, when the User chose a certain Radio button, a select list
appeared.

The best that I can guess is that this is done with CSSS' layering capabilities,
presumably raising a different layer to the top? But I stil don't know how
to pull it off.

In my application, I do need to show/hide a select list vs. a text input
box, depending on which Radio button the User chose.

Thanks again,
Take care,
Dave Straley

Hi Dave,

Well this was a bit trickier than I thought, but it should give you what you
want:

<HTML>
<BODY>

<p><Input name=rad1 type=radio onclick="whichrad()" language=vbs>First radio
<p><Input name=rad1 type=radio onclick="whichrad()" language=vbs>Second
radio
<p><input name=txt1 type=text value="" size=15 style="display:none">
<p><select name=sel1 size=1 style="display:none">
<option value=1>option1
<option value=2>option2
<option value=3>option3
</select>

<script langauge=vbs>
sub whichrad()
if rad1(0).checked="True" then
txt1.style.display=""
sel1.style.display="none"
elseif rad1(1).checked="True" then
txt1.style.display="none"
sel1.style.display=""
end if
end sub
</script>
</BODY>
</HTML>

The MSDN library is an invaluable site, I find, although at times I still
have to figure things out by myself. <G>

cheers,

steve

Steve,

Wow! That's great! You gave me a solution which works "right out of the
box"! Thanks so much. The behavior of the form elements is just what I
was looking for. I owe you one, Steve!

Take care,
Dave Straley

Happy to help.

Don't put it inside of a form though. It screws up then.

cheers,

steve
