Trouble with facebook sdk quickstart - facebook

Question

Following directions here https://developers.facebook.com/docs/javascript/quickstart
I started with a mostly blank HTML page, just the HTML, Body tags, and a simple Hello World.
I copied and pasted directly from the quickstart page but get nothing (but Hello World does Load).
I have an app ID (I wasn't sure if I should include the {} or not, tried both ways, no change.
I added the code from section "Using the SDK to add Social Plugins", "Using the SDK to trigger a Feed dialog" etc and nothing. Running on CentOS/Apache, server is fine. Not sure what I'm missing. Thoughts?
Thank you for your time.

Maybe something like the following will be of help?
<div id="fb-root"></div>
<!-- Load the Facebook JavaScript SDK -->
<script src="//connect.facebook.net/en_US/all.js"></script>
<script type="text/javascript">
// Initialize the Facebook JavaScript SDK
FB.init({
appId: 'YOUR_APP_ID',
xfbml: true,
status: true,
cookie: true,
});
// Check if the current user is logged in and has authorized the app
FB.getLoginStatus(checkLoginStatus);
// Login in the current user via Facebook and ask for email permission
function authUser() {
FB.login(checkLoginStatus, {scope:'email'});
}
// Check the result of the user status and display login button if necessary
function checkLoginStatus(response) {
if(response && response.status == 'connected') {
//alert('User is authorized');
// Hide the login button
document.getElementById('loginButton').style.display = 'none';
// Now Personalize the User Experience
//console.log('Access Token: ' + response.authResponse.accessToken);
} else {
//alert('User is not authorized');
// Display the login button
document.getElementById('loginButton').style.display = 'block';
}
}
FB.ui(
{
method: 'feed',
name: 'The Facebook SDK for Javascript',
caption: 'Bringing Facebook to the desktop and mobile web',
description: (
'A small JavaScript library that allows you to harness ' +
'the power of Facebook, bringing the user\'s identity, ' +
'social graph and distribution power to your site.'
),

},
function(response) {
if (response && response.post_id) {
alert('Post was published.');
} else {
alert('Post was not published.');
}
}
);
</script>
<input id="loginButton" type="button" value="Ligin with Facebook" onclick="authUser();" /></div>
<div class="fb-like" data-send="true" data-width="450" data-show-faces="true"></div>

You have a syntax error in your JS
SyntaxError: syntax error purity2.html:26
To fix it, remove }; from line 19
FB.Event.subscribe('auth.authResponseChange', function(response) {
if (response.status === 'connected') {
console.log('Logged in');
} else {
FB.login();
}
});
}; // this
it should be like
FB.Event.subscribe('auth.authResponseChange', function(response) {
if (response.status === 'connected') {
console.log('Logged in');
} else {
FB.login();
}
});
Now your code should work
