Let's say I have an iframe hosted on www.my-iframe.com. And let's say that my iframe is embedded in a page on a different domain using:
<iframe src="http://www.my-iframe.com" scrolling="no" height="500" width="100%"></iframe>
Please note that the iframe tag has the attribute scrolling="no".
I only have access to edit the iframe code, not the pages on which my iframe is embedded. This makes it so I cannot change the scrolling attribute of the iframe html tag or the overflow: hidden; css styling of the iframe.
Is there a way that I can force a scroll bar to appear when necessary from within the iframe code?
Any help/advice is appreciated!
What you could try is maybe using a JS library to simulate a a scrollbar, there are plenty of them on the internet.
Here are a few examples (neither unordered nor necessarily the best ones): iScrollJS
fullPage.js
jQuery scrollbars

I have been tasked to use this approach a SharePoint 2013 site, so here goes.
Background: - I have a page in a SharePoint 2013 site, which has a "content editor" webpart displaying a page from within the same domain/site collection. The below code (which is not mine) I have placed in the content editor and it displays the page all fine.
Issue - My requirement is to "remove the globalnav" from the page within the content editor which I presume is using an Iframe. Now I can use the F12 dev tools with IE11 and find the CSS class which is the follow - ms-dialog #globalNavBox and set the display to "none" this is exactly how I want it to look.
The only thing I do not know how to achieve here is how to make this happen via using some sort of code on the page displaying the embedded page.??
this is the code I am using in the content editor to display my page I want to modify.
#mydiv{
width:1280px; height:1000px;
overflow:hidden;
;
}
#myframe{
;
top:-190px;
left:-100px;
width:1080px;
height:1000px;
}
</style>
<div id="mydiv">
<iframe id="myframe" src="/gen/genInduction/Lists...blah scrolling="no"></iframe> </div>
now I have no idea how to add in the code (if I can) to remove the css .ms-dialog #globalNavBox {display: none;} so that when the page is displayed the globalnav is removed.
I hope this makes sense as this is the first time I have used this site to ask a question. I have also searched endlessly before I asked this question and have tried various things to make this work but I just cant/understand how to make this happen.
Place the following in the page after the iframe
<script>
document.getElementById("myframe").contentDocument.getElementById("globalNavBox").style.display="none";
</script>
I believe you'll still be able to access the iframe's content since they both belong to the same domain, unless the iframe is sandboxed (which the example clearly shows it isn't). Adding to JBiserkov's slick streamlined answer, this will cover some concerns with loading of the iframe. Under many circumstances, an iframe might be a little late to the party, so you should be prepared for that. The following links helped me understand iframes:
Iframes, Onload, and Document.domain
Iframe Tutorials
-Reference to the iframe
var iFrame = document.getElementById('myframe'),
-Reference to the iframe's document object
-This shorthand conditional expression is the key to accessing any content inside the iframed page.
iDoc = iFrame.contentDocument ? iFrame.contentDocument : iFrame.contentWindow.document,
-Reference to the target element #globalNavBox
gNav = iDoc.getElementById('globalNavBox');
-When the iframe is loaded, grab globalNavBox's style to "display" and set to "none"
iframe.onload = function () {
gNav.style.display = 'none';
};
I have an iFrame that is included in my HTML and is available when the page loads. When the page first loads, the iFrame has no content/src. I am using jQuery to insert content into the iFrame dynamically. When a user clicks a link on my page, the contents of the iFrame are updated. All of this is working for me.
However, I am struggling to adjust the height of the iFrame when new content is loaded. I have tried several solutions on Stack Overflow but with no success. Here is my iFrame code:
<iframe id="myframe" width="100%" frameborder="0"></iframe>
Here is my jQuery that changes the HTML inside of my iFrame:
emailOpened.find('#myframe').contents().find('body').html(email.body);
This works for me. I just need my iFrame to adjust its height based on the height of the content being injected. I have failed on all attempts with this part.
Update
Here is my new HTML:
<iframe id="myframe" width="100%" frameborder="0">
<body onload="parent.resizeIframe(document.body.scrollHeight);">
</iframe>

how to properly display an iFrame in mobile safari
https://encrypted.google.com/search?q=iframe+resize+ios+issue
I had to support mobile devices as well and ended up using it after some hours of research and testing. I've also used the provided message channel to send messages to the inner document back and forth.
Call this function directly after the html has been changed.
function resizeIframe() {
var newHeight = document.getElementById('myframe').contentDocument.body.scrollHeight;
document.getElementById('myframe').style.height = parseInt(newHeight,10) + 10 + 'px';
}
I have designed a page for a customer that incorporates a PDF via an iframe tag. So, if the pdf is large, there are two scrollbars: one of the page and one of the embedded pdf into the iframe (PDF is loaded by the integrated Adobe plugin in the browser). How can I resize dinamically the iframe height in order to maintain the page scrollbar only?
Thanks,
Francesco.
You can use overflow to prevent scrollbars
HTML:
<iframe src="..." class="pdf-frame"></iframe>
CSS:
.pdf-frame {
overflow: visible;
}
Well if you have said <iframe id="myiframe" ...
You could use jQuery to resize it by setting the height dynamically:
$("#myiframe").height('someHeight');
or in javascript:
document.getElementById("myiframe").style.height = "someHeight";
or if you are looking for something else there is an interesting article here (Dynamically resize divs with jQuery).
I'm using code in an iFrame to embed news in a website. I am unable to customize the iFrame.
<iframe src="http://www.google.com/uds/modules/elements/newsshow/iframe.html?topic=n,p,s,n&rsz=small" frameborder="0" width="728" height="90" marginwidth="0" marginheight="0"></iframe>here
If you want to customize content of iframe , its not possible in cross domain iframe. browsers not allow to access any DOM object of cross site. and if it is same domain then its possible. I think in your case its looking cross domain frame.
You can customized the iframe itself (border width, color, etc.) but cannot change the contents of the source URL. I will note, however, that if the source URL did not set a background color, you can set the default content background color from the iframe using a CSS style statement.
BTW, do note that Google "newsshow" has been deprecated for a long time and now no longer works.

Explanation of problem in full below, you could probably just skip to the code at the bottom if you want.
What happened is a impatient client wanted his swf banners converted to html5 without having to actually code them from scratch. So i utilized Google's new tool, Swiffy. I then tried to place this new generated html5 page in the header of the clients wordpress site. I have gotten it to load as an iframe but the problem that I am encountering is when you click on a link on the loaded html5 page, it just loads the linked page in the iframe, not the parent page/window (which is to be expected). I tried a bunch of other methods, and tried changing the AS2 links in the .fla as well but no luck. I am guessing Swiffy can not read every AS2 code, and so it has been ignoring my "_blank", "_parent" when I use getURL. Anyway, I have been trying to get it so when the iframe unloads to go to the linked page, it uses Java to just open the link on the parent page. But iframes cant use the onunload event, but I am pretty sure framesets can. So this is the code I was trying and it doesnt work.
<frameset rows="100%" onunload="window.open('http://www.goaefis.com/about-aefis/what-is-aefis/','_parent');">
<frame src="www.goaefis.com/banner_Test.html" frameborder="0" scrolling="no" />
</frameset>
Any help will be super appreciated.
try to use the "target" on your frames.
Here's a example:
