Forum OpenACS Q&A: javascript for hiding/showing form elements

1: javascript for hiding/showing form elements

Posted by David Kuczek on 08/31/02 05:28 PM

I want to integrate a js into survey_simple that hides a form element
whenever a user doesn't have to fill it out. Whenever the user wants
to fill it out anyways, he just clicks on a button and the form
element opens up.

I found an very good example, but it only works on IE:

This example also works on Mozilla, but the form gets exchanged with
whitespace and not with nothing:

Does anyone already hava such an implementation or knows how to merge
the two little example scripts?

it would be a lot easier to leave the input visible, but disabled. good luck. :)

how about putting form elements onto different layers with <div> and then stacking them & changing visibility props? this wont, however, work in many (if not all) older browsers.

Funny, I thought that our bboard would cut out scripts, but noap...

I don't think the 3.x bboard calls util_close_html_tags out of the box. (And you'd still need to add "syn(SCRIPT) discard" to the list.)

nice, albeit does not work in Opera, at least on the bboard page.

I suppose that if it doesn't work on the bboard it shouldn't work anywhere else on Opera... I am not sure what part of the code must be changed to make it Opera compliant, but you could recognize the browser with a js-sniffer and then automatically exchange that part of the code.
