AJAX: getting a label to act like its field

[jhaagmans]

Hi,

I have a check_box and on activating it, I want an extra field to show
up.

I thought I'd do this by calling a remote_function called "toggle"
in :onchange. In toggle.rjs, I'd do something like page.toggle and
have the visibility toggled. I'm not sure whether it works: I haven't
tried it yet. What I did try was setting up a form with a hidden field
(by default the check_box isn't ticked, so the field should be
hidden), but the field label is still there. Is there a way to do this
so I can toggle both the field and the label?

Any other suggestions to do this (without page.toggle maybe?) are very
welcome as well.

Thank you.

Call page.toggle twice - once on the label, once on the field ?

Or put both the label and the field in an enclosing element (e.g. a
span or a div) and toggle visibility on that.

Thank you both, I had specified an id for the label and called
page.toggle on it as Frederick suggested, but I suspected a label to
be able to do more than that. Apparently not. This will do the trick.

Is there a way to toggle an object directly from :onchange, by the way?
