I have an iFrame content that I use on third party websites.
I'm trying to get this iFrame content to go in full-screen browser mode.
This works OK when using the content alone as main document, but not on these third party websites (lms), that have often several iFrames nested, and my content is always the final nested one of course.
What I don't understand is that document.body.webkitRequestFullScreen() is well defined in my document but it returns undefined.
I'm making an hypothesis: Do all nested iFrames need to have the allowFullScreen attribute? Or Can the full-screen work if only the upper iFrame have it?
And if my problem comes from this attribute, is there a way to allowFullScreen to all parents iFrames of the document?

For the portal I am testing now, I came with the problem that I could not create any xpath locators, after some time I figured out that it was because of an '#document', this cuts the path and makes the simple "copy xpath" to direct the path to a completely different element.
<iframe id="FRAMENAME" src="/webclient/workspace/launch-task/REMbl?ds=BP" width="100%" height="100%" frameborder="0" data-navitemname="navitemname" style="" xpath="1">
#document
<html>
CODE....
</html>
I found the solution for this is it is simply add a switchTo like this:
driver.switchTo().frame("FRAMENAME");
This works and makes the rest of the code to work properly but, takes some extra time processing this command till the code moves to the next line.
So I would like to ask, is there is a better solution for this? something smarter/faster?
I am concerned that when the point where I have lots of scripts comes, the execution time will take too long.
I don't use id locators for example because they are all dynamic so sometimes a xpath is required.
Thank you!
To work with elements inside iframe you must switch to this specific iframe.
Your solution .switchTo().frame("FRAMENAME"); is correct. Selenium does not have any other ways to work with iframe wrappers.
inline frames
As per the documentation in Using inline frames, an inline frame is a construct which embeds a document into an HTML document so that embedded data is displayed inside a subwindow of the browser's window. This does not mean full inclusion and the two documents are independent, and both them are treated as complete documents, instead of treating one as part of the other.
iframe structure and details
Generally, an iframe element is in the form of:
<iframe src="URL" more attributes>
alternative content for browsers which do not
support iframe
</iframe>
Browsers which support iframe display the document referred to by the URL in a subwindow, typically with vertical and/or horizontal scroll bars. Such browsers ignore the content of the iframe element (i.e. everything between the start tag <iframe...> and the end tag </iframe>). Browsers which do not support iframe (or have such support disabled) does the opposite, i.e. process the content as if the <iframe...> and </iframe> tags were not there. Thus, the content matters, despite being ignored by some browsers.
So to summarize, inline frames do not mean an include feature, although it might sometimes serve similar purposes.
Note that, when inline frames are used, the browser (if it supports them) sends a request to the server referred to by the URL in the iframe element, and after getting the requested document displays it inside an inline frame. In this sense inline frames are a joint browser-server issue, but only the browser needs to be specifically iframe-aware; from the server's point of view, there's just a normal HTTP request for a document, and it sends the document without having (or needing) any idea on what the browser is going to do with it.
Something Smarter
As per the best practices while switching to an iframe you need to induce WebDriverWait as follows:
Switch through Frame Name (Java Sample Code):
new WebDriverWait(driver, 20).until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.name("frame_name")));
Switch through iframe XPath (Python Sample Code):
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.XPATH,"//iframe[#id='ptifrmtgtframe' and #name='TargetContent']")))
Switch through iframe CssSelector (C# Sample Code):
new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.FrameToBeAvailableAndSwitchToIt(By.CssSelector("iframe#twitter-widget-0")));

Inline frames vs. normal frames
I've been playing around with DOM and BOM in JavaScript through Google Chrome's console trying to change locally input values, colors, etc...on different websites. I stumbled on a website that used iframe tags for it's form. I tried to change the value of the inputs located inside the iframe but couldn't get it done. My understanding is iframe incorporates a separate webpage inside of the one currently viewed.
My question is simple how do I access the tags inside of the iframe?
Things I tried so far:
document.getElementById("")
document.getElementsByTagNames("")
window.frames
window.parent
So an iframe is an inline frame, and what that inline frame contains is the building blocks to build a website, or display someone elses website. If you know DOM traversal you would basically have to select that iframe, and then go to select the DOM objects within that iframe from there to manipulate those.
iframe = $('#myId');
iframe.contents().find('htmlelements');
Here is a sandbox environment to begin understanding the traversal portion:
http://jsfiddle.net/fDFca/
I have embedded a player from a site which streams a channel using an iframe. I am able to make the iframe responsive. But the content i.e the video player inside the iframe is not adaptive to the changes in viewport. I have tried several solutions from internet but all of them make the iframe responsive but not the content inside.
Is there any way I can make the video player inside the iframe responsive?
Please note that I don't have access to the source code of the player.
Here's the link to the html file: IFrame Code (I was not able to create a working fiddle of this. So shared the file instead)
Please note that I don't have access to the source code of the player.
You are in trouble
The one major thing to know while dealing with iframe is the source of the iframe
iframe source has the same domain as the main page which renders this iframe: In this case the browser will let you put your hands on the iframe contents and manipulate it as desired. As both the main site and the iframe are unders same domain it means you are a authorized person so you can change the contents if required.
So even if you don't have access to the source code of the file there are still way's to make your contents responsive if they are in the same domain. This would require Jquery
iframe source domain is not the same as your main page which renders this iframe: In this case you cannot do much with the iframe except displaying it in your page. The browser will not allow you to change any stuff on this iframe. This is a security protocol followed in all the browsers.
what happens if at all we are given access to manipulate the contents - Eg: I can render youtube in my iframe of my website and change all the instances of the string "youtube" to my own name, thus making this entire site look like my own. Also I can manipulate the ajax calls, jquery stuff etc,etc.. and get data from the site.
I am developing a system where I will display content in a browser in an embedded application. The normal browser navigation controls cannot be used but instead will have javascript running in a wrapper round the page. The content will be coming from the same domain but I cannot pre-process the content. Needs to be compliant with IE8+ and latest of FF and chrome.
The things the javascript needs to do are..
Load in new content
Detect when the content has fully loaded
Set focus to elements
Detect which link currently has focus
Retrieve lists of links on the page
Trigger links
What is the best way to place the content html pages within the wrapper page? eg
frames
iframe
div
Both iframes and divs could work. The final choice will depend on the details of your implementation, and is also a matter of personal taste.
With divs, the html becomes part of your wrapper page. The risk is to have conflicts between the inserted content and the rest of the page (css, html ids for example).
An iframe creates a sandbox and avoids conflicts. The downside is that the layout is not easy to adjust as the content lives in its own document. html5 introduces new iframe attributes like "seamless", but they won't work in IE8.
As above, Iframes may be best; however they are deprecated and don't always give the best results. An alternative would be to set a div for the content, and Ajax the content into the frame. You can then access it through the dom to get links etc.
To decide which would be best I would consider what content is being loaded - full HTML documents (with doctype, head, metadata etc) will be problematic without I frames.
If the content being loaded is just plain text, maybe with a few basic HTML elements, I would ajax it into a div
