I'm able to retrieve data inside an iframe using
browser.iframe
But when I try to interact with elements inside this iframe, like for ex. click on a button, watir won't locate any of them.
I tried with all kind of elements inside this iframe, but nothing happens.
There could be more than one iframe on your page so you might be targeting the wrong one (just writing browser.iframe will target the first iframe on page.
You can could inspect the page and check if there are more than one iframe, or type:
puts "there are #{browser.iframes.count} on page"
and run the script again.
ideally iframe has an id so you could write
my_iframe = browser.iframe(id: "something")
my_iframe.buttons.last.click
# or
my_iframe.button(text: "ok").click
if it's not a secret, right click => inspect page you are automating and screenshot/paste html here. Or share the whole code that doesn't work for you.

I'm adding a facebook share button to each post on a Wordpress (Using Facebook Share Button New plugin), it works ok for each post/page except when i'm loading them trough ajax, the result it's a normal Facebook like button but the popup (to write a comment) appears inside the button it is not expanded.
To check go to: http://iwanttobeher.com/ and then click on any face at the bottom of the page, then test the like button and you'll see what happens.
I don't know what to do, i tried to FB.XFBML.parse() after loading the content but the result is the same.
Switching to HTML5 didn't help in our case. What did was to remove the FB object just prior to new content being inserted into the page via Ajax:
delete FB;
wrapper.html(response.data);
We reload full pages via Ajax and so new page content recreates the FB object and re-initializes XFBML anyway. Not sure if this workaround would work if we reloaded only parts of the page though.
The original answer is here.
I've managed to fix it by changing the implementation to HTML5 instead Iframe or XFBML using Facebook's tool to generate like buttons: https://developers.facebook.com/docs/reference/plugins/like/
I have a bookmarklet that opens a dialog (in reality an iframe) and extracts some information. When the dialog is dismissed I want to put that information into edit text fields on the original page in the browser (like the way LastPass will automatically fill-in login forms on a page).
Is this possible? I'm thinking that same-origin-policy will prevent this, but maybe there is a way (without installing extensions such as greasemonkey, etc).
Edit: to be more precise: the bookmarklet appends a DIV to the original page; that DIV contains an IFRAME that loads my page; this page fetches some information; once this information is fetched within the IFRAME I want to remove the DIV and (somehow) put that information into the original page.
The issue I face is communicating the information in the IFRAME back to the original page.
What you are looking for are the functions addEventListener and postMessage.

How do you use window.postMessage across domains?
I am trying to implement content browsing like it is done on Facebook when user is browsing the photos. I guess everyone is familiar with that photo browsing where you can click "next" and "previous" and immediately get the next or previous photo (you can also navigate using arrow keys).
When you click "next" for example you notice that the page does not refresh - only the content. At first I thought it is done using plain ajax calls which refresh only the "content" in this case the image, description and comments. But then I noticed that also URL in the "Location" toolbar of my browser is changed!
I tried to inspect this using Firebug and discovered that when you click "next" only the next photo is downloaded and I still don't know from where the comments & image meta data (description, time, tags,...) are loaded.
Can someone please explain how this technique is done - page URL changes without page refresh (or even without page "blinking" if it refreshes from cache).
I know how to change page content using ajax but URL of that page stays the same all the time. If I click on "refresh" button I get the first page again. But not on Facebook since even the "window.location" is changed every time without actual redirect.
The other thing I noticed is that the bottom toolbar (applications, chat, ...) is "always on top". Even if you change the page, this toolbar is not refreshed and always stays on top - it doesn't even "blink" like other pages that are refreshed (either from webserver or from local cache). I guess this is the same technique as above - some kind of "fake" redirects or something?
The Answer is pushState
if (window.history.pushState)
window.history.pushState([object or string], [title], [new link]);
You will smile :)
I've tried to change through facebook images, and this is what I saw:
In Firefox:
The page URL is not changing. Only the hash is changing. This is a technique used to allow crawlers to index the content. What happens is this:
User clicks on "next"
JS loads the next image with tags, comments, etc and replaces the old content with them.
JS changes the hash to correspond the new image
urls look like this:
http://www.facebook.com/home.php?#!/photo.php?fbid=1550005942528966&set=a.1514725882151300.28042.100000570788121&pid=3829033&id=1000001570788121 (notice the hash)
As for the second question, this is just a benefit of the technique above. When you are on facebook, the page rarely gets actually refreshed. Only the hash is changed so that you can send links to other people and crawlers can index the content.
In Google Chrome:
It seems that chrome hassome way to change urls without refreshing the page. It does that by using window.history.pushState. Read about it here.
urls look like this: http://www.facebook.com/photo.php?fbid=1613802157224343&set=a.1514725288215100.28042.1000005707388121&pid=426541&id=1000001570788121 (notice that there is no hash here, but still the url is changing along with images)
In Epiphany:
Epiphany doesn't change the URL when the image changes.
urls look like this: http://www.facebook.com/photo.php?fbid=1441817122377521&set=a.1514725882215100.28042.1000005707848121&pid=3251944&id=1000200570788121 (there is no hash, and the URL stays the same when changing the image)
(don't have other browsers to verify right now)
The one technique not mentioned here is the window.onhashchange() method (supported in ie8+ and most others) which they might have used
You may noticed that the page url remain the same. What is changed, however, is page hash (the part after # in the url).

I am not trying to track clicks or anything like other people - I just want to put a browser within a browser that can go back, forward, refresh, accept user-entered URLs, and store bookmarks. Can flash/silverlight/ajax/whatever do this? If so, how?
How about:
Solution 1:
Create or use an existing ActiveX Web Browser control.
And let your web/page host that ActiveX, or host multiple controls.
Solution 2:
Put an iframe inside a UserControl, a textbox and a go button.
Get the user provided url from textbox.
Change the src of the iframe when user clicks the go button.
_
<iframe id="iFrame" name="myFrame" src="http://bing.com"
width="100%" height="300" frameborder="0">
<p>Does your browser support iframes?</p>
</iframe>
--EDIT--
This is in response to your comment; you posed 3 questions:
For 1, thats correct, ActiveX works for IE, more specifically for Windows; there are ways you can install ActiveX for different browsers, but it(the ActiveX) would require windows OS. See this.
For 2, try handling that using JavaScript; something like following within iframe block.
<p>Back</p>
Checkout these examples.
For the third one, if I understand you correctly then you can always parse the url when user clicks onto the Go button; and respond accordingly before rendering the page.
flash can do basic html (AFAIK) not sure about silverlight.
you will struggle to do it with javascript/iframes. Especially back/forward/refresh buttons. If you are on the same domain you have some control over the iframe, but once it leaves your domain, you lose control
Would using an iframe or an object with type="text/html" be useful to you in terms of being able to embed a page within a page? Either method effectively permits loading a separate page within a page with little side-effect.
I am working on a site where the main part of it is driven by an ajax style navigation system using anchors in the url to define the application state.
On top of this I now need to support IFrames that are loaded on top of this application. The problem I'm having is that the back button breaks if I make use of fragments.
I've created a very simple sample, that isn't using any of the ajax libraries. All it has is a link that adds an anchor to the url and an iframe, with some normal links in it.
If I click then anchor link first, then I click the link in the iframe, I would expect the first back click to take back to the original iframe page and the second click to remove the anchor from the url.
I'm aware of all the various solutions out there (YUI, reallysimplehistory, jquery plugin) and they all work great, but they don't cater for iframes.
I'm also aware that I could add some JS to the framed pages and possibly route all navigation through the parent page, but I'm hoping that isn't necessary.
So the question is, can anyone explain what is going on inside the history object in this sample? Secondly is there anything I can do from the parent iframe to coax the history object to pick up these navigation entries?
Note: I'm only enquiring about FF/Safari/Chrome in this sample. IE needs to looked at separately.
