Hi can somebody help me. I can't get rid of this error message in Chrome 9.0 beta, Chrome 8.0 or Firefox 3.6.13:
"Unsafe JavaScript attempt to access frame with URL 'http://apps.facebook.com/myapp/' from frame with URL 'http://myapp.dyndns-office.com/'. Domains, protocols and ports must match."
I'm using the FacebookSDK version 4.1.1 CSMvcFacebookApp in the Samples folder.
I have this script in my Site.Master page located in Views/Shared:
<script language="javascript" type="text/javascript">
$(document).ready(function () {
FB_RequireFeatures(['CanvasUtil'], function () {
FB.XdComm.Server.init("<%= ResolveUrl("~/xd_receiver.htm") %>");
FB.CanvasClient.startTimerToSizeToContent();
});
});
</script>
I have xd_receiver.htm in my root directory, and presumed that the above javascript code was all I needed to do verify my domain with facebook.
Is my presumption correct or has things changed?
I even tried moving the FB code out of the JQuery ready function like so:
<script language="javascript" type="text/javascript">
FB_RequireFeatures(['CanvasUtil'], function () {
FB.XdComm.Server.init("<%= ResolveUrl("~/xd_receiver.htm") %>");
FB.CanvasClient.startTimerToSizeToContent();
});
</script>
But this doesn't work either ...
Can anybody shed some light as to what I'm doing wrong or how I get xd file to work using the SDK/MVC IFrame solution...
FB.CanvasClient.startTimerToSizeToContent() is firing because I don't have the scroll bars appear in my application, so that proves that FB_RequireFeatures function is working. But as to whether FB.XdComm.Server.init is doing it's part I'm just not sure as to how I go about testing this ???
The content of my xd_receiver.html file in my root directory is:
<!--<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

XdCommReceiver.js exists as I just copied the pasted the url into the browser. Are my paths correct or have facebook up and change the url's etc ... ?
I understand that my main concern here is that Safari won't run my app at all if I don't get this cross domain stuff sorted out now.
Any help here would be much appreciated :-\
Thanks

<< ADDITIONAL COMMENT >>
Is there a built in mechanism in the latest version of the FacebookSDK v 4.1.1 to make this cross domain stuff just work? Did the developers of the SDK think about this issue? Or have I just brought up a future feature ... :-\
Here's the code you need to have in your cross-domain scripting channel file:
<html><body><script type="text/javascript" src="http://connect.facebook.net/en_US/all.js"></script></body></html>
Here's the code to initialize the FB Javascript SDK. Put this at the very end of your HTML files, substituting in the appropriate values and URLs.
<script type="text/javascript" src="http://connect.facebook.net/en_US/all.js"></script><script type="text/javascript">FB.init({appId: '1234567890', status: true, cookie: true, xfbml: true,channelUrl: 'http://example.com/xss_channel.htm'});</script>
Optionally, put this in your web.config where the XSS channel file is located. This lets browsers cache the file indefinitely as recommended by Facebook.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<location path="xss_channel.htm">
<system.webServer>
<httpProtocol>
<customHeaders>
<add name="Expires" value="Tue, 01 Jan 2030 16:00:00 GMT" />
</customHeaders>
</httpProtocol>
</system.webServer>
</location>
</configuration>
And finally, if you're using XFBML, place this namespace definition in your <html> to make XFBML work in IE:
xmlns:fb="http://www.facebook.com/2008/fbml"
You are using the old Facebook Connect Javascript. The Facebook C# SDK is not compatible with the old Javascript SDK. You should use the new Facebook Javascript SDK (as was included in the sample). http://developers.facebook.com/docs/reference/javascript/

I can read english to some degree but I'm not good at writing.
Then I appologize for any rudeness.
I don't know well about wicket but I think it very good.
I want to deploy on wicket Javascript application made by LibGDX ,but on wicket's HTML file it does not work.
LibGDX logo was shown but next is not.(Maybe it seems to be not found next file (xxxx.cache.html) ??)
Please Tell me how to work Javascript(GWT) application on wicket.
Chrome shows this error.

My Javascript application is made by GWT which is client only created by LibGDX.
(LibGDX is multi platform game framework.
It can create WebGL application from java by GWT compiled.)
I think it can work in wicket because this GWT application is client only.

I'm working on a simple FB app of a type I've done many times before. It works perfectly outside FB but once it's in FB, the youtube embed simply doesn't load.
I pulled the code out into a test file, and it still won't load. Here's the code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=UTF-8" />
</head>
<body>
<iframe width="669" height="391" src="http://www.youtube.com/embed/48P1jc5tyTw" frameborder="0" allowfullscreen></iframe>
</body>
Absolutely nothing displays when this is loaded as an app on a FB page. The FB debugger says "Can't Download Could not retrieve data from URL."
Any ideas?
Try changing the src of the iframe to "https://...".
Since Facebook is served over HTTPS, your browser will block any content from loading on the page that's not over HTTPS too. Fortunately, youtube supports https versions of their URLs.
This is my first time posting a question on this site, but certainly not the first time finding answers in it.
I have used stackoverflow as a resource to fix several issues I've faced with my new blog, that is until last night, when I found this issue which I just can't fix.
When I try to share the home page of my blog, I don't get the proper image specified in the og:image tag... once I check my site via de FB debugger, it shows me this:
https://developers.facebook.com/tools/debug/og/object?q=ivanfuentes.com
Curiously enough, I do not find any issues when I check for a page, or a post:
https://developers.facebook.com/tools/debug/og/object?q=ivanfuentes.com%2Fvideos%2F
https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fivanfuentes.com%2Fthe-popularity-contest%2F
So, I know it's an issue that is generated in the home page only, but during the last 18 hours, have been unable to find it.
I have OG meta tags specified dinamically via a wordpress plugin... currently, it's "Facebook AWD", but I've had several other Facebook sharing, all-in-one's, and OG plugins, which give me the same results in the debugger, which makes me think I messed up somewhere else. I have no embarrassment in admitting I'm quite a newbie, so it's highly likely I messed up while trying to modify some code... probably when I added a few lines to make the site IE compliant?
Hope I gave enough information, and someone gets to help me, as this is not only about the proper image being displayed on a Facebook link, but rather about me likely having a mess in my code, and that could (WILL) mean trouble once I make any mods/updates to my site in the future.
Thanks for the time!
Your html is a complete mess and that's why the debugger is complaining.
Visiting your page and looking at the code I can see this:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

Two problems there:
The sdk code is inserted twice
In both cases there's a div placement before the body
In the debugger result for this page when clicking the bottom link (Scraped URL: See exactly what our scraper sees for your URL) you can also see broken html but in another variation:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><body>
<div id="fb-root"></div>
<script>
...
</script><meta http-equiv="content-type" content="text/html; charset=utf-8">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script>
...
</script><title>Ivan Fuentes Hagar</title>
There problems here:
The body definition is right after the html
There's no head definition
All of the tags which suppose to live inside the head are inside the body
The sdk script is loaded inserted twice
In both cases I found 3 occurrences of the <div id="fb-root"></div>.
As you can see you have some fixin' up to do with the html output of your wordpress.
I'm not sure why the outputs is different for the debugger, I thought that maybe due to the user agent string, but trying curl --user-agent "facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)" "http://ivanfuentes.com/" returns the exact results as with the browser.
I am developing Sencha touch application that will work on iPhone. Now application is ready and works fine in phone browser. But, now I want to distribute my application so I am using PhoneGap.
All my HTML and JavaScript pages are deployed at http://170.60.26.20:8099/Sencha/Html/index.html. Now i want to load that URL using phonegap. Suggest me the steps how could I do this.
I have installed phonegap-1.2.0-0 version.
Create new Phonegap App in xcode and you just need to modify already exist index.html file in www folder.
You can use window.location javascript method to load your web app in phone app.
In PhoneGap(Cordova).plist, add your server to the ExternalHosts list and make OpenAllWhitelistURLsInWebView to YES.
Please try following code to run your html pages in phonegap app.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<!-- Change this if you want to allow scaling -->
<meta name="viewport" content="width=default-width; user-scalable=no" />
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<title>LoadUrl
<!-- If you application is targeting iOS BEFORE 4.0 you MUST put json2.js from http://www.JSON.org/json2.js into your www directory and include it here -->
<script type="text/javascript" charset="utf-8" src="phonegap.js"></script>
<script type="text/javascript" charset="utf-8">
function onBodyLoad()
{
document.addEventListener("deviceready",onDeviceReady,false);
}
/* When this function is called, PhoneGap has been initialized and is ready to roll */
function onDeviceReady()
{
// do your thing!
window.location="http://web.me.com/djpinter1/iPhone/jqtouch/demos/main_tabbar/#ui";
//window.location="http://170.60.26.20:8099/Sencha/Html/index.html";
}
</script>
</head>
<body onload="onBodyLoad()">
</body>
</html>
In your xcode , start a new project as phonegap project. Then copy the files from your project folder to www folder in the phonegap project.Keep in mind that index.html file should be in the parent folder , otherwise you have to change the url accordingly in the corresponding class that invokes a webview.
You can follow this link
http://wiki.phonegap.com/w/page/39991939/Getting%20Started%20with%20PhoneGap%20iOS%20using%20Xcode%204
Hope it will help
I'm trying to configure that my facebook application will be resizeable.
The docs at http://wiki.developers.facebook.com/index.php/Resizable_IFrame
talk about facebook connect cross-domain receiver URL.
and in the JS code i need to enter the 'site relative url to xd_receiver.htm'.
what's that?
what code should be in that HTML file ?
thanks
This is a file saved to your local web server. It allows Facebook to save a cookie that you have access to. Basically, it allows Facebook Connect to work.
Easiest thing to do is just place it in your web root (http://example.com/xd_receiver.htm)
This file should contain the following:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
