how to get at div property in iframe

[firepages]

Hi, I use the following code for hiding an object in the main window...

function hide(obj) {
div=B.dom?document.getElementById(obj).style:B.ie4?document.all[obj].style:B.ns4?document.layers[obj]:0;
div.visibility = (B.ns4)? "hide" : "hidden"
}

is there anyway I can target and show/hide a div in an iframe ?

(eg window.iframe_name.div_name)

?
cheers!

An iframe on a page belongs to the frames collection of that window so...

self.frames['iframeName']

ah , whilst I am here :)

how would I refresh 1 iframe from within another iframe in the same docment I mean if I had...

window.iframe1
window.iframe2

how could I get iframe2 to reload iframe1 without reloading the main window ?


full of questions today ain't I :D

Heh, no problem. To be honest with you, I almost always use absolute references to frames when using them. The case is VERY rare when I think it is not the preferred method (such as 3-4 nested sets of frames...ya that happens often :rolleyes:) This rule sees more flexibility when iframes come into play...

Making an absolute reference to a frame is just like an absolute link...start from the top and go down, and coincidentally, the keyword for finding the top window in a nested frame structure is top!

top.frames['iframe1']
top.frames['iframe2']

Being absolute, these references will work accurately from ANYwhere within the window/frame structure

Note: I'm not sure if using the frames collection is necessary (as opposed to the dot-syntax), but it is my preference)

cheers muchly Beetle ,
//
div=B.dom?window.frames[frame].document.getElementById(obj).style:B.ie4?document.all[obj].style:B.ns4?document.layers[obj]:0;
div.visibility = (B.ns4)? "show" : "visible"
//

did the job , (I know the NS4 bit will cark it BTW)

Shouldn't that be...

var f = window.frames[frame];
div=B.dom?f.document.getElementById(obj).style:B.ie4?f.document.all[obj].style:B.ns4?f.document.layers[obj]:0;

???

It seems you only satisfied the getElementById condition in your ternary....

Hi, Beetle the exact code I was using was ...

function hideiframe(frame,obj) {
if(BB==1){
div=B.dom?window.frames[frame].document.getElementById(obj).style:B.ie4?document.all[obj].style:B.ns4?document.layers[obj]:0;
div.visibility = (B.ns4)? "hide" : "hidden"
}}

(the 'BB' bit is just a check that the browser detection has finished)

& yes you are right I have ignored IE4 there which I must fix !, as for NS4 it wont recognise the iframe anyway and NS4 users won't actually be able to view this page, just I reuse a lot of existing code hence the dinosaur layers bit :)

cheers again
