IFRAME closed captioning component???

[Clancy]

Hello to all.

I just finished my first web development class so now I have a little knowledge and could be considered dangerous.

I have no real clue on how to make this idea work but it sure seems feasible and would immensely appreciate any assistance or direction to make this happen.


What I want to happen is to have the user have the ability to turn an IFRAME, ON and OFF at anytime say within a series of 25 continuously linked pages.

OK that doesn't sound like a big deal. The problem is how do I make the IFRAME stay open or closed as the user moves from page to page through the sequence of pages? I am trying to create closed captioning component for a training piece. So if the user decides to use the CC the IFRAME would stay open through all the pages of a section and the content of the IFRAME would automatically change to correspond to the new page as the user advances through a section.

I have done this in flash by loading and unloading movies. So to show the CC the user hit a button that unloaded the top layer movie to expose the CC on a lower layer and back on to close or hide it again. That was a pretty simple task but I can not get my head around JavaScript and IFRAME to make this happen and could sure use a whole lot of help.

Thank you
Clancy

Welcome to TSDN.

I assume you mean you want to hide/display the iframe. Use the display property:

document.getElementById(frameid).style.display='none'

to hide and st it to 'block' to display.

If all you're doing is displaying text, an iframe is probably way overkill (plus it breaks web standards).

Instead, just put a DIV on your page and set its display property as acoder mentioned.

Whenever you need to change the text of the DIV, just use:

document.getElementById('theId').firstChild.nodeValue = text;
