Iframe Height Adjustment To Loaded Content?

Dec 9, 2007

First time posting here. Have been enjoying all the resources available to us, very helpful. My problem:

Recently started learning css / java - i have a web page with an iframe on the index pages within a div tag, which then loads all other pages into this iframe. The thing is i require the iframe to adjust its height size according to the content loaded.

After lots of searching a have come across only one that worked for me,however it only seems to work in IE and not firefox and the like.

Change The Height Of A Iframe Depending On The Loaded Content?

Dec 26, 2010

I'm looking for a script to change the height of a iframe depending on the loaded content. I found some scripts who let it work when a webpage loads in the iframe.

But when the height of the page changes by javascript animations.

Like a box is getting 200px higher by a javascript action. The page won't reload by this action so the iframe height remains in it's current height.

Anyone has a good script that the iframe height even changed on javascript commands?

JQuery :: Chrome Calculating Height Before Content Is Completely Loaded?

Jun 1, 2011

I'm working on a script to pass the content height to some other element. The whole script is within the document ready function, but somehow Google Chrome thinks the content height is 0 (zero), because it's so fast. When I set a timeout it works correctly, but I don't really like this solution because of the delay.

var contentHeight = ($('body').height();
setTimeout(function() {
var contentHeight = ($('body').height();

Calculating Height Of Iframe Content After Inserting The Content?

Nov 10, 2010

I'm using JQuery to write content into an otherwise empty iframe like so:

Code:

$('#ifrmID').contents.find('html').html(htmlContent);

The content is coming from an Ajax request. The content gets used more than once on the page for other purposes which is why I don't simply change the iframe src--I have to do an ajax request regardless so I'm trying to avoid multiple calls.

After I load the content, I need modify the height of the iframe so it fits snuggly around the content.

Calculating the height isn't a problem with the exception that it's not always correct and I think it's because the calculation is happening before images have downloaded.

I don't seem to be able to rely on a `load` or `ready` event to delay the calculation. The load event is the only one that tiggers on a change of iframe content, but it doesn't see the new content.

Code:

$('iframe').each(function () {
$(this).load(function () {
alert($(this).contents().find('html').html());
});
});


This will output '<html><body></body></html>' even though I have successfully inserted different content.

Any suggestions on what I'm doing wrong, or if it's possible to do what I want reliably?

Note that a general JS solution will be appreciated as much as a JQuery one.

Resize My Iframe(ifr) Based On The Content Loaded In It?

Aug 27, 2010

I have been having an issue with this script to resize my iframe(ifr) based on the content loaded in it.I am half bald from this issue. Works perfect in IE7 & 8 but not in FF or Chrome.FF works "almost" - It resizes on first page loaded but doesn't resize if the iframe content is changed until refreshed. (example: If I load search results which shows 10 results and then click one and it loads the page which isn't as high as the search results page was then it just stays at the larger height until I refresh and then resizes correctly.)

.JS Code:

How To Auto Height IFrame Content Script

Sep 27, 2010

I'm making a wordpress theme that will have a SMF forum incorporated into one of the pages. I've decided to use an iframe that calls in the forum (which is in the same domain), after trying several of the auto height scripts, including ones I used before with success, I got nothing. I'm not sure if it's a wordpress thing, but the scripts I'm so familiar with just don't want to work. Since forums change their height with all the different pages, this is an essential script for me. The only script (a new one) that somewhat works is the following:

Code:
<script language="javascript" type="text/javascript">
function resizeIframe(obj) {
obj.style.height = obj.contentWindow.document.body.scrollHeight + 'px';
obj.style.width = obj.contentWindow.document.body.scrollWidth + 'px';
}
</script>

Which eventually gets called with:
Code:
onload='javascript:resizeIframe(this);'
inside the iframe tag.

Now, this seemed to work just fine, but now the height of the page gets added the more I browse. If for example I go to a topic with a lot of replies (meaning, a long page height) and I browse back to the index page, that extra height isn't gone. You can see what I mean here: [URL]. I was wondering if there is something that can be done to this script to stop this and properly resize the iframe. The other script I've used was: [URL]. Which worked great as you can see here: [URL].

Ajax :: IFrame Content (JSP File) Height Resizing

Apr 22, 2010

Having a problem with iframe resizing when the iframe body is a jsp file which contains a dynamically built ajax table. Users select different options from a drop down. All but 1 is a standard static jsp file. The other is a jsp file with a dynamic ajax table which is generated the second the user select this option from the drop down. Problem is the javascript is not getting the correct height for the dynamically ajaxed jsp file.

Here is the iframe which is loading the contents file.
<iframe id="Editor" name="Editor" src="" scrolling="no" frameborder="0" allowtransparency="true" onLoad="resizeIframeToFitContent(this)"></iframe>
Resize call:
function resizeIframeToFitContent(iframe) {
iframe.height = Editor.document.body.scrollHeight + 300;
iframe.width = Editor.document.body.scrollWidth;
} // resizeIframeToFitContent

As a current workaround I am adding 300 manually to the height this works but throws the height of the normal jsp files well out and makes the page to tall.

Dynamically Resizeing IFRAME Height Based On Content

Jul 8, 2005

I have the following script resizeing my iframe based on height. The problem is if my site is on one domain say http://mydomain.company.com and the target page is on another domain say http://anotherdomain.mycompany.com the script does not resize the page. I cannot add anything to the pages i am linking to because they live in a CVS repository so i cannot call a function or passs information in that way.

is there any way to make my script work? I'm so fustrated, I'm so close! help!


<!--this script auto resizes the height of the iframe based on contents-->
<script type="text/javascript">
<!--
function resize_iframe(){
document.getElementById("_iframe").height=768 // required for mozilla/firefox bugs, value can be "", null, or integer
document.getElementById('_iframe').height=window.frames["_iframe"].document.body.scrollHeight
}
// -->
</script>

which uses the following iframe
<iframe width=96% id="_iframe" name="_iframe" src="intro.htm" scrolling="no" frameborder="no" ALLOWTRANSPARENCY="true" onload=resize_iframe();></iframe>

Determining When An IFrame Is Fully Loaded?

Feb 4, 2009

i'm dynamically creating an iframe on my page. the source for that iframe is a php page that prompts the user to download an excel file. sometimes it can take a little while for this file to be built by php.

i need a way to determine when the php page in the iframe is completely done.

currently, this is what i have.

Code HTML4Strict:
<iframe onload="iframeLoaded();" src="report.php"></iframe>

the problem with onload is that it seems like it fires as soon as the page is even referrenced within the iframe...not completely finished.

How To Prevent An IFrame From Being Loaded Automatically

Oct 4, 2006

I have a page which embeds an iframe like so:

<iframe src="" id="test"></iframe>

somewhere in my JavaScript code in the page, I set the src attribute of the ifrmae. This causes the iframe to load the page as it should.

If I leave this page to another and click 'back' in the browser, I return to my page, and the iframe gets loaded automatically, using the last src value it had.

I don't want that. I only want the iframe to load when my JavaScript code modifies the src attribute.

It is as if the browser remembers in its cache the last value of the iframe src.

May 31, 2006

I generate in a js variable some code of tthis kind:
