Hello. Ive got an iFrame at a page that shows several pages content, if you pressone or the other button. These pages are web yep editable, and the content of the first one is too short and the content of the second one is too long, so I would like to make the iframe get the size of the content by itself, without scroling. Is it possible?
Thanks.

I think this can be done with the inline html object, but I always have a mess at this point…
is there any tutorial or something to make this been understood?
Thanks

Are both the iframe content and the outer page that contains the iframe served from the exact same server? (Everything – hostname, protocol, port EXACTLY the same?) If so, you can force an iframe to take on the size of its content page using some JavaScript. But if any part of this is different, the Same Origin Policy will fail, and a script from one host cannot affect content from another.
It’s best if the iframe URL does not have any hostname information in it, as though the code was like this:
<iframe src="/path/to/page.html"></iframe>
rather than
<iframe src="http://example.com/path/to/page.html"></iframe>
If the first example looks like your code, then the iframe’s origin will always match that of the outer page, and you can use this trick.
In the Page / HTML Markup / Before section, paste the following code:
<script type="text/javascript">
(function(){
var iframe = document.querySelector('iframe');
iframe.addEventListener('load', function(){
var new_height = iframe.contentWindow.document.body.offsetHeight;
iframe.style.height = new_height + 'px';
});
})();
</script>
This script requires that there only be one iframe on the page in order to work. If you have applied Twitter or Facebook Actions to your page, that may no longer be true. Let me know if this works for you, and if you need to adjust it to work around the multiple iframe problem, there is a way to do that.

Forgot to mention – this goes on the page that holds the iframe, not the page that loads into the iframe.

Hello Waltd. Sorry, but I didnt see your answer, and next day I had a look and didnt see at that date, so I thought I had not been answered…Sorry.
At your question, yes, the content of the iframe are pages at the same site, web yep created pages, a contact form, and so.
I have a question. With your code, you resize the iframe, but it doesnt push down the conten below it, is it?
Thanks a lot

That will depend on your page construction - ie is it inline?

If your iframe is inline within a parent element, and other content appears beneath it in the regular content flow, like this:
+----------------
| some html box
|
|+--------------
|| iframe here
||
||
|+--------------
| More content
| Below that...
+-----------------
Then if the iframe is adjusted by this script, it will push the content below it down the page. But if you just drew the iframe in place on the page, then you won’t get that effect, because drawn (layered) elements always exist on their own unique plane, and cannot interact with any other elements on the page.

Hello. Nothing… I have some content in my page, with the navigation buttons, a video, and a text. Below this I draw an html box with the iframe inside it (I click inside the html item, and the cursor flash, and then I paste my iframe). After that, I press return twice, and a I paste a graphic. And the iframe doesnt push down the graphic… The iframe is called iframe, as you put in your code before …
You can beleieve me, the inline items are my nightmare…

Nothing again. Ive just tried it in a new blank page, with noting else than the html item, and inside it, the buttons, the iframe and an image below, and nothing, doesnt push… And another thing is that the graphic doesnt catch the padding, because I want it 25px from left, I set 25px left padding, and it appears at 0 from left. The iframe accepts the padding correctly.
Well, I could put a scroll in the iframe content… Is it psible to make a scroll bar? The last time I asked in the forum, you advise me to make a scroll with an up button and a down button, but nobody likes this scroll, because it not an intuitive one…

The scroll I mean is similar to the scroll that appears with the iframe, but just with the vertical bar, not with the horizontal one.

Without seeing this online try this.
Select the iFrame item, use the Right arrow key once, insert an HTML item. Resize that HTML item to suit your image and set the background of the HTML item as your image as centre, centre, no tiling in either direction.
You may or may not have to set the Float on the HTML item to suit and you can set a margin on it too (25px).
But that is me working blind.

How are you adding your iframe - are you using the iframe action because it appears that the iframe on that page is wrapped in paragraph Tags. It really needs to be a standalone item to get it to do what you want.
And what finished effect are you trying to achieve - can you show us what it should look like.

Yes, with the iframe action. Perhaps the paragraph is because you told me to insert a tab before the iframe… I have deleted it now.
The finished I would like is the one you can see in the jpg image
Thanks

If you insert an Action item inline in an HTML box, Freeway will wrap it in a P tag because it treats any such as if it was a single character of text. I may dig into that Action at some point, and add the logic from my CrowBar Action to it so it can detect when it is improperly nested and deal with this issue. In the meantime, try this:
display, Value: block. (If you’re viewing this in Mail, don’t include the back-ticks, they are just here for formatting in the Web view, where they will be invisible anyway.)I suspect that you may be seeing the effect of the iframe element being natively display: inline-block in many browsers. Unless your iframe is wide enough to force any text below it to not appear to its right, it may do that. Although, that doesn’t seem likely, since the P tag is natively display:block (unless you’ve done something to force that to no longer be true) and so it should push the remaining content in the parent block down when its child iframe resizes, too.

No - I suggested you use the Right Arrow key (bottom right on your keyboard) when you had the iFrame selected. This moves the insertion point immediately after the item you have selected.

I don’t know if you have given up on this one or not but I was trying Walter’s script and couldn’t get it to work for me so I found another solution that I have managed to implement at http://deltadesign.co/FW7Test/iframes/iframes1.html
This uses the following Script in the Head of your page:
<script language="JavaScript">
<!--
function calcHeight()
{
//find the height of the internal page
var the_height=
document.getElementById('resize').contentWindow.
document.body.scrollHeight;
//change the height of the iframe
document.getElementById('resize').height=
the_height;
}
//-->
</script>
And the iframe is called using:
<iframe src="yourpage.html" onLoad="calcHeight();" scrolling="NO" frameborder="0" width="100%" height="20" name="resize" id="resize"></iframe>
I haven’t tested it in any Browsers other than Safari, Chrome and FireFox on Mac
