Is there a way to duplicate IEs document.all functionality in Mozilla and NS? I need to retrieve a list of tag elements without knowing their IDs. For example...

Code: Select all

var frms = document.all.tags(A');
for (i=0; i<frms.length;i++)
{
     alert(frms[i].id);
}

The above example will retrieve a list of [tt]<A>[/tt] tag elements. Is there something comparable to this functionality in Netscape or Mozilla?

Well, I haven't heard of [tt]document.all[/tt] functionality in IE, but my guess is that it's not standards-compliant code. If you want to fine all of the links on a page, you can right-click on the page, select "View Page Info", and click the "Links" tab. That should give you a complete list of links on a page.

Found it.

Thanks Fulvio for this interesting link.

An important thing to remember is that this will not break existing scripts that check for document.all, it will only work in cases where the script assumes it is running in IE, and does not first check to be sure that document.all works. If document.all is checked for, Mozilla will continue to block its use and act as it always has.

So, if the script checks for browser type, Mozilla will use the code wrote for Mozilla, sounds fair. But if the script does not check the browser type... Mozilla is to behave like MSIE.

So now Mozilla is to support [tt]<marquee>[/tt], [tt]document.all[/tt] and all those used to be MSIE-only tags? When will they bring back the Communicator's [tt]<layer>[/tt] tag?

When will they bring back the Communicator's [tt]<layer>[/tt] tag?

If I'm not mistaken, they have done something like that already in Netscape 7.2. I'm probably confusing this with something else, but here's an example.

1) Go into Composer, add something such as a table or image.

2) Select the object and click on the thumbtack icon in the toolbar. The object is now its own layer, and you can move it around the screen and put it in different places. You can also send it to the back of another layer or to the front.

But, besides, wasn't the LAYER tag superseded by CSS?

In fact Netscape 7 doesn't generate a Netscape 4-style <layer> when you do that. It gives the object |position: absolute| style: CSS. The layer tag is truly dead. I can't imagine its ever resurrection.

On the other hand document.all first surfaced in a release build in September, in Firefox 1.0 PR 1. It makes me weep for besmudged purity, but it's expected to help more than it hurts. document.all is probably the single most common IE-malapropism, and I've seen actual websites, the only thing standing between them and working just fine in Firefox was pseudo-document.all as implemented in FF 1.0 PR 1. It's probably a good thing.

So the support of [tt]document.all[/tt] is only in Firefox (starting from version 1.0 PR), not in Mozilla ?

This was actually put in the Firefox 1.0PR release notes. From the release notes:


This was also found in Bugzilla Bug 248549

Yes Firefox is the only official Mozilla release with document.all support to date. I guess that might be an important enough distinction between it and other Mozilla/Netscape browsers to keep in mind when dealing with reports of sites not working. I think it doesn't make all that much difference, though. In my limited experience, it makes an important difference at just the occasional website. Sometimes for better, sometimes not.

PS Gosh, computers on the network around Mozilla seem a little ragged this morning.

Yes Firefox is the only official Mozilla release with document.all support to date.

Mozilla 1.8 alpha (see http://www.mozilla.org/releases/ ) supports it, too.

[akbash]

Well, OK. I guess 1.8 alpha could be counted as an official release. Anyway it's coming to browsers everywhere in time. Though I wouldn't hold my breath over Moz 1.7 or Netscape 7.
