Why am I getting this error for my Facebook Like button?
Uncaught ReferenceError: _onloadHook is not defined
Why? My code is below:
<!DOCTYPE html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<html>
<head>
<script src="http://connect.facebook.net/en_US/all.js#xfbml=1"></script>
<script type="text/javascript">
//Initialize facebook
FB.init({
appId : '12345',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
channelUrl : 'http://www.abc.com/channel.html', // channel.html file
});
</script>
</head>
<body>
<div id="fb-root">&开发者_高级运维lt;/div>
<fb:send href="http://abc.com/blah" font="lucida grande" ref="codes_popup"></fb:send>
<fb:send href="http://abc.com/blah" font="lucida grande" ref="codes_popup"></fb:send>
</body>
</html>
Edit: When I have multiple this will happen. When I only have one "send" button , the error is not there.
For every extra "Send" button, the error occurs.
This is a bug in the Facebook Platform; it has already been reported as bug #20041.
Place the Facebook JS library and JS code scripts under the fb-root div:
<!DOCTYPE html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">
<html>
<head>
</head>
<body>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script type="text/javascript">
//Initialize facebook
FB.init({
appId : 'XXX',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
channelUrl : 'http://www.abc.com/channel.html', // channel.html file
});
</script>
<fb:send href="http://abc.com/blah" font="lucida grande" ref="codes_popup"></fb:send>
</body>
</html>
I have been getting the exact same error today.
As ifaour mentions, the FB documentation says that you need to place the FB <script> tags under the <div id="fb-root"></div>. However, in his example and in the FB documentation, they put the scripts directly under the <div id="fb-root"></div>. I was doing that and still getting the error the OP mentions. I was finally able to solve the problem by moving the FB <script> tags to the very bottom of the page, right before the closing </body> tag. I believe what was happening is that some of my other scripts were interfering with the loading of the FB scripts. Hope that helps.
You should call the facebook javascript using the upgraded async method. This will make sure that the whole DOM is loaded so that the fb:root is already on the page.
http://developers.facebook.com/docs/reference/javascript/FB.init/
<script>
window.fbAsyncInit = function() {
FB.init({
appId : 'YOUR APP ID',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
channelUrl : 'http://www.yourdomain.com/channel.html', // Custom Channel URL
oauth : true //enables OAuth 2.0
});
};
(function() {
var e = document.createElement('script');
e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
e.async = true;
document.getElementById('fb-root').appendChild(e);
}());
</script>
Also critically important is to add support for OAuth 2.0 http://developers.facebook.com/blog/post/525/
oauth : true
As of Oct 1 if you don't have that your apps will stop working properly.
