My page jumps to the top when I embed this gdrive iframe, once you click on the iframe:
<iframe height="400px" frameborder="0" width="600px" src="https://docs.google.com/document/d/1u9NFjTPBd-9mucQUPvkqLP84iV6uaEcJNF5vQdHmYh8/edit?usp=sharing&rm=embedded"></iframe>
JSFiddle: https://jsfiddle.net/0qpe53os/
Question: Why does it do so and how can I prevent it from doing so?
I tried to preventDefault without any luck. Thanks a lot in advance for your help.
I'm not sure if this is useful. By the way you could use the onload attribute to scroll the page down:
onload="scroll(0,screen.height);"
<iframe height="400px" frameborder="0" width="600px" src="https://docs.google.com/document/d/1u9NFjTPBd-9mucQUPvkqLP84iV6uaEcJNF5vQdHmYh8/edit?usp=sharing&rm=embedded" onload="scroll(0,screen.height);"></iframe>
From my investigation, its not caused by the iframe itself. Its cause by the javascript executed by the embedded google docs. When the editing area of the google docs receives the focus this happens. If you access the menu area nothing happens unless it results something being added to the editing area. I tried restricting the iframe with sandbox attribute and this behavior no more happens, but of course you cannot use the google docs.
Sorry no solutions to suggest.
You could use javascript to check if the iframe is the active element and jump back to it if it is active.
if(document.activeElement.tagName == 'IFRAME') {
document.activeElement.scrollIntoView()
}
See this Jsfiddle for a working example.
What are the possible ways in which I can preserve an iframe embedded in a view in between my route changes?
As the route changes from Route A-> Route B, Ember destroys the View for A. My View for A has an embedded iframe which I would love to preserve and not reload when Route A is revisited.
So far, I tried moving my iframe to a parent view that is not destroyed when exiting Route A but browsers reload iframes when you move them around in the DOM, so its a moot exercise.
Indeed nesting is the right choice for you problem of iframe.
Here is a detailled example with a counter to see when the iframe is reloaded.
|-home
|-about
|-elsewhere
This important part of the fiddle is :
<div class="border-row">
This is home
<iframe src="http://emberjs.com/" width="100%" height="150px" onload="App.HomeController.countLoadings()"></iframe>
count : {{App.HomeController.loadcount}}<br/>
isDestroying : {{isDestroying}}<br/>
isDestroyed : {{isDestroyed}}
</div>
{{outlet}}
You can see that the iframe only reloads when you actually move to another part of the hierarchy route. If you navigate between home and about, the iframe stays the same.
i am using feeds module for import news items.By using views,i display the news title,description and item url.In this,when user hit the item urls means its loads that particular site inside my site.I try to use Iframe by way of "output rewrite option" in views.But that page load fully instead of load inside my site.I use following code for that.
<iframe src="[url]" width="100%" height="300">
<p>[url]</p>
</iframe>
Any one please guide me resolve this.
thanks
This can be achieved using the target attribute on an a tag. For example when the user hit's the item URL it would load in the target window which in this case is the frame. Take for example the code below.
test
<iframe name="target_frame" src="http://www.google.com" frameborder="0" width="300" height="300"></iframe>
The frame initially loads google.com but once the link is clicked the target attribute on the a directs the click to the frame which has the same name attribute, in this case target_frame
You can read more about the target attribute here http://www.w3schools.com/tags/att_a_target.asp
Heres a tricky one . .
I have a webpage (called PageA) that has a header and then simply includes an iframe. Lets call the page within the iframe PageB. PageB simply has a bunch of thumbnails but there are a lot so you have to scroll down on PageA to view them all.
When i scroll down to the bottom of the pageB and click on a thumbnail it looks like it takes me to a blank page. What actually happens is that it bring up the image but since the page that is just the image is much shorter in height, the scroll bar stays at the same location and doesn't adjust for it. I have to scroll up to the top of the page to view the picture.
Is there anyway when i click a link on a page that is within an iframe, the outer pages scroll bar goes back up to the top
thks,
ak
#mek after trying various methods, the best solution I've found is this:
In the outer page, define a scroller function:
<script type="text/javascript">
function gotop() {
scroll(0,0);
}
</script>
Then when you define the iframe, set an onload handler (which fires each time the iframe source loads i.e. whenever you navigate to a new page in the iframe)
<iframe id="myframe"
onload="try { gotop() } catch (e) {}"
src="http://yourframesource"
width="100%" height="999"
scrolling="auto" marginwidth="0" marginheight="0"
frameborder="0" vspace="0" hspace="0" >
</iframe>
The nice thing about this approach is it means you do not need to make any changes to the pages included in the iframe (and the iframe contents can happily be in another domain - no cross-site scripting issues).
Javascript is your best bet. You can use the scroll() method to scroll back up to the top of your IFRAME. Add a javascript handler in the body load so that each time you click a thumbnail, call a function that calls scroll() to scroll up.
I've spent a considerable amount of time trying to figure out how to scroll to the top of the iframe from within the PHP code I was calling (from within the parent ASP.NET page). I never figured I could scroll to the top using the same javascript but in the iframe's onload event. Thanks!
I have built a basic data entry application allowing users to browse external content in iframe and enter data quickly from the same page. One of the data variables is the URL.
Ideally I would like to be able to load the iframes current url into a textbox with javascript. I realize now that this is not going to happen due to security issues.
Has anyone done anything on the server side? or know of any .Net browser in browser controls. The ultimate goal is to just give the user an easy method of extracting the url of the page they are viewing in the iframe It doesn't necessarily HAVE to be an iframe, a browser in the browser would be ideal.
Thanks,

I did some tests in Firefox 3 comparing the value of .src and .documentWindow.location.href in an iframe. (Note: The documentWindow is called contentDocument in Chrome, so instead of .documentWindow.location.href in Chrome it will be .contentDocument.location.href.)
src is always the last URL that was loaded in the iframe without user interaction. I.e., it contains the first value for the URL, or the last value you set up with Javascript from the containing window doing:
document.getElementById("myiframe").src = 'http://www.google.com/';
If the user navigates inside the iframe, you can't anymore access the value of the URL using src. In the previous example, if the user goes away from www.google.com and you do:
alert(document.getElementById("myiframe").src);
You will still get "http://www.google.com".
documentWindow.location.href is only available if the iframe contains a page in the same domain as the containing window, but if it's available it always contains the right value for the URL, even if the user navigates in the iframe.
If you try to access documentWindow.location.href (or anything under documentWindow) and the iframe is in a page that doesn't belong to the domain of the containing window, it will raise an exception:
document.getElementById("myiframe").src = 'http://www.google.com/';
alert(document.getElementById("myiframe").documentWindow.location.href);
Error: Permission denied to get property Location.href
I have not tested any other browser.
Hope it helps!
document.getElementById('iframeID').contentWindow.location.href
You can't access cross-domain iframe location at all.
I use this.
var iframe = parent.document.getElementById("theiframe");
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
var currentFrame = innerDoc.location.href;
HTA works like a normal windows application.
You write HTML code, and save it as an .hta file.
However, there are, at least, one drawback: The browser can't open an .hta file; it's handled as a normal .exe program. So, if you place a link to an .hta onto your web page, it will open a download dialog, asking of you want to open or save the HTA file. If its not a problem for you, you can click "Open" and it will open a new window (that have no toolbars, so no Back button, neither address bar, neither menubar).
I needed to do something very similar to what you want, but instead of iframes, I used a real frameset.
The main page need to be a .hta file; the other should be a normal .htm page (or .php or whatever).
Here's an example of a HTA page with 2 frames, where the top one have a button and a text field, that contains the second frame URL; the button updates the field:
frameset.hta
<html>
<head>
<title>HTA Example</title>
<HTA:APPLICATION id="frames" border="thin" caption="yes" icon="http://www.google.com/favicon.ico" showintaskbar="yes" singleinstance="no" sysmenu="yes" navigable="yes" contextmenu="no" innerborder="no" scroll="auto" scrollflat="yes" selection="yes" windowstate="normal"></HTA:APPLICATION>
</head>
<frameset rows="60px, *">
<frame src="topo.htm" name="topo" id="topo" application="yes" />
<frame src="http://www.google.com" name="conteudo" id="conteudo" application="yes" />
</frameset>
</html>
There's an HTA:APPLICATION tag that sets some properties to the file; it's good to have, but it isn't a must.
You NEED to place an application="yes" at the frames' tags. It says they belongs to the program too and should have access to all data (if you don't, the frames will still show the error you had before).
topo.htm
<html>
<head>
<title>Topo</title>
<script type="text/javascript">
function copia_url() {
campo.value = parent.conteudo.location;
}
</script>
</head>
<body style="background: lightBlue;" onload="copia_url()">
<input type="button" value="Copiar URL" onclick="copia_url()" />
<input type="text" size="120" id="campo" />
</body>
</html>
You should notice that I didn't used any getElement function to fetch the field; on HTA file, all elements that have an ID becomes instantly an object
I hope this help you, and others that get to this question. It solved my problem, that looks like to be the same as you have.

I like your server side idea, even if my proposed implementation of it sounds a little bit ghetto.
You could set the .innerHTML of the iframe to the HTML contents you grab server side. Depending on how you grab this, you will have to pay attention to relative versus absolute paths.
Plus, depending on how the page you are grabbing interacts with other pages, this could totally not work (cookies being set for the page you are grabbing won't work across domains, maybe state is being tracked in Javascript... Lots of reasons this might not work.)
I don't believe that tracking the current state of the page you are trying to mirror is theoretically possible, but I'm not sure. The site could track all sorts of things server side, you won't have access to this state. Imagine the case where on a page load a variable is set to a random value server-side, how would you capture this state?
Do these ideas help with anything?

Does this help?

I only tested this in firefox, but if you have something like this:
<iframe name='myframe' id='myframe' src='http://www.google.com'></iframe>
You can get its address by using:
document.getElementById('myframe').src
Not sure if I understood your question correctly but anyways :)
You can use Ra-Ajax and have an iframe wrapped inside e.g. a Window control. Though in general terms I don't encourage people to use iframes (for anything)
Another alternative is to load the HTML on the server and send it directly into the Window as the content of a Label or something. Check out how this Ajax RSS parser is loading the RSS items in the source which can be downloaded here (Open Source - LGPL)
(Disclaimer; I work with Ra-Ajax...)
Ok, so in this application, there is an iframe in which the user is supplied with links or some capacity that allows that iframe to browse to some external site. You are then looking to capture the URL to which the user has browsed.
Something to keep in mind. Since the URL is to an external source, you will be limited in how much you can interact with this iframe via javascript (or an client side access for that matter), this is known as browser cross-domain security, as apparently you have discovered. There are clever work arounds, as presented here Cross-domain, cross-frame Javascript, although I do not think this work around applies in this case.
About all you can access is the location, as you need.
I would suggest making the code presented more resilitant and less error prone. Try browsing the web sometime with IE or FF configured to show javascript errors. You will be surprised just how many javascript errors are thrown, largely because there is a lot of error prone javascript out there, which just continues to proliferate.
This solution assumes that the iframe in question is the same "window" context where you are running the javascript. (Meaning, it is not embedded within another frame or iframe, in which case, the javascript code gets more involved, and you likely need to recursively search through the window hierarchy.)
<iframe name='frmExternal' id='frmExternal' src='http://www.stackoverflow.com'></frame>
<input type='text' id='txtUrl' />
<input type='button' id='btnGetUrl' value='Get URL' onclick='GetIFrameUrl();' />
<script language='javascript' type='text/javascript'>
function GetIFrameUrl()
{
if (!document.getElementById)
{
return;
}
var frm = document.getElementById("frmExternal");
var txt = document.getElementById("txtUrl");
if (frm == null || txt == null)
{
// not great user feedback but slightly better than obnoxious script errors
alert("There was a problem with this page, please refresh.");
return;
}
txt.value = frm.src;
}
</script>
Hope this helps.
You can access the src property of the iframe but that will only give you the initially loaded URL. If the user is navigating around in the iframe via you'll need to use an HTA to solve the security problem.
http://msdn.microsoft.com/en-us/library/ms536474(VS.85).aspx
Check out the link, using an HTA and setting the "application" property of an iframe will allow you to access the document.href property and parse out all of the information you want, including DOM elements and their values if you so choose.
