How can I hide controls in a form? 1

[Ditter]

I'm looking for tecniques for hiding controls in a form, I'm not quite sure if it is posible...

For example, if a RADIO button is pressed, make invisible a SELECT or something like this.

Can I do that? How?

In IE (i'm testing in 5.5) you can just access it my name or id and say nameofbox.style.visibility='hidden'

otherwise, for older versions and for netscape, you may have to put it inside a layer and hide the layer, but I'm not sure jared@aauser.com

no it's only that for netscape the syntax isn't the same
i'm not 100% sure but i remember it's not "hidden" but "hide"

 

[jaredn]

for IE the two strings to use are:

visibile/hidden

NS i think:

hide/show jared@aauser.com

Hi all

This one's giving me a headache too. I am wanting to dynamically hide and view a couple of combo boxes, depending on the value selected in a third combo box, which is no problem under IE but I am trying all kinds of things under Netscape. I tried putting the combo boxes on a layer but Netscape (I am testing on 4.74) doesn't seem to like it - I get the text from each of the options displayed in a layer instead of getting the combo boxes. I seem to recall that combo boxes are implemented as separate window objects, so maybe they are incompatible with layers other than the base layer.

Has anyone managed to do this?

i remember a thread of someone who add almost the same problem, but he had the combo in a table cell
i don't remember the forum, the thread number, nor the answer .... sorry i'm afraid i'm not a great help for you !! but you should perform a search in this forum ...

this works in NS6:

<form>
<select name=&quot;don&quot;>
<option value=&quot;a&quot;>aaaa
<option value=&quot;b&quot;>bbbb
</select>

<select name=&quot;don1&quot;>
<option value=&quot;a&quot;>aaaa
<option value=&quot;b&quot;>bbbb
</select>

<select id=&quot;don2&quot; onChange=&quot;this.form.don.style.visibility='hidden';this.form.don1.style.visibility='hidden'&quot;>
<option value=&quot;a&quot;>aaaa
<option value=&quot;b&quot;>bbbb
</select>

</form> jared@aauser.com

Thanks for the example Jared. In NN4.74 the onChange gives the JavaScript error &quot;this.form.don.style has no properties&quot;. NN6 is implementing the new style DOM. Your example also works in IE5.00.2314.1003 . As my page is destined for the web rather than intranet, version 4 browser upwards, I am still looking for an NN4 solution. For the time being I am putting some not applicable &quot;n/a&quot; entries as the last option in the combo boxes and if NN4 I am flipping the combo values to &quot;n/a&quot; at the point where I would really prefer to hide them altogether.

Hi,

Did you find a solution? I would like to show/hide a couple input cols based on a radio button. Please post your solution if you found one...

Thanks,

This is a blast from the past - I had completely forgotten about it. No I didn't find a solution, so left it as described above. Personally I wouldn't bother too much about NN4.7 any more unless you have a NN4.7 intranet or are particularly attracting NN4.7 traffic. Analysis of traffic to one of my websites suggests that hardly anyone is using NN4 any more (only a couple of visitors this year).
