When my iframe loads I need parent page to load different content(header,footer) while iframe its still there. I added to iframe :
window.top.location = "http://mysite.com";
It loads the new parent page but its reloading over and over again.
How can I enable only one load/iframe load, or some solution.
I have tried with
window.onload = function() {
if(!window.location.hash) {
window.location = window.location + '#loaded';
window.location.reload();
}
}
but it does nothing.
Thank you.
you just can't reload the iframe parent only without reloading the iframe too! If you want to change some content in parent page you must do it with javascript from the parent page and not the iframe.
And if you want to catch the "iframe loaded event" you must do it from inside the iframe. Looks like an impossible situation but you can still do it!
You need to let iframe and parent page comunicate, and you can do it with html5 postmessage (works even if parent and iframe are in different domains!). If you need to have IE7 compatibility too you can use easyXDM javascript library instead of postMessage, just search for example in their site.
Simply do a postMessage from iFrame when jQuery(document).ready() (or any similar event) is triggered, the parent page must have a listner waiting for this message for trigger the header/footer/anything change event.
Saw alot of manual loads of iframes in answers, but I need the page to automatically load the fist menu option and I am using nyroModal (class=iframe which opens it iframe style with nyroModal).
The reason for this is the menu for a bunch of other iframe content is in this iframe as well and I'd like it to stay open and the menu stay in this auto opened iframe.
Hopefully this makes sense to someone.(?)
You can use the manual function inside the event handling:
$(window).load(function() {
// my code to open manually an iframe using nyroModal
});
You can get the snippet to open the iframe at this page: Open iframe manually in nyroModal
I have an iframe that gets loaded when i click on a tab on a page. When i use Firebug to look at the iframe on IE8, all i see is:
iframe id=tabContextFrame class=contextFrame contentEditable=inherit src=/xyz.dt?forward=show&layouttype=NoHeader&runid=1234 name=tabContextFrame url=/xyz.dt?forward=show&layouttype=NoHeader&runid=1234 scrolling=auto
and that's it.The hierarchy below the iframe can't be seen. I want to click on a link within the iframe. To find the elements within the iframe, I did a selenium.click("on the tab that loads the iframe") and then selenium.getHtmlSource(). From this source, I can at least locate my link of interest. I did a selenium.click("//span[text()='Link']") but it doesn't seem to do anything. Any ideas please?
Here is the code:
selenium.click("//span[text()='tab that loads iframe']");
Thread.sleep(5000);
selenium.selectFrame("tabContextFrame");
selenium.mouseOver("//span[text()='Link']");
selenium.mouseDown("//span[text()='Link']");
selenium.mouseUp("//span[text()='Link']");
Thread.sleep(5000);
selenium.selectFrame("null");
I'm guessing you are using Selenium 1.0. Have you looked at Selenium 2.0 and WebDriver. I found the following and it worked for me:
Q: How do I type into a contentEditable iframe? A: Assuming that the
iframe is named "foo":
driver.switchTo().frame("foo");
WebElement editable = driver.switchTo().activeElement();
editable.sendKeys("Your text here");
Sometimes this doesn't work, and this is because the iframe
doesn't have any content. On Firefox you can execute the following
before "sendKeys":
((JavascriptExecutor) driver).executeScript("document.body.innerHTML = '<br>'");
This is needed because the iframe has no content by default:
there's nothing to send keyboard input to. This method call inserts an
empty tag, which sets everything up nicely.
Remember to switch out of the frame once you're done (as all further
interactions will be with this specific frame):
driver.switchTo().defaultContent();
I found this on http://code.google.com/p/selenium/wiki/FrequentlyAskedQuestions
Use driver.switchTo().defaultContent(); first then do your operation
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,
Adam
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?
http://www.quirksmode.org/js/iframe.html
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.
