只需使用JavaScript SDK的FB.login方法，并在你自己的按钮上点击它。

How would I replace the generated facebook login button with my own custom one?
I am guessing it can either be done by creating a function of the code that fires up the dialog or driving the button off the screen with some css tricks. I'd prefer the first solution.
How could I make my own button do what theirs does and get rid of the the default button?
Here's the example code from the facebook developers site:
require 'fb/facebook.php';
$facebook = new Facebook(array(
'appId' => 'X',
'secret' => 'X',
));
// See if there is a user from a cookie
$user = $facebook->getUser();
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
$user = null;
}
}
?>
<!DOCTYPE html>
<html xmlns:fb="http://www.facebook.com/2008/fbml">
<body>
<?php if ($user) { ?>
Your user profile is
<pre>
<?php print htmlspecialchars(print_r($user_profile, true)) ?>
</pre>
<?php } else { ?>
<fb:login-button></fb:login-button>
<?php } ?>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId: '<?php echo $facebook->getAppID() ?>',
cookie: true,
xfbml: true,
oauth: true
});
FB.Event.subscribe('auth.login', function(response) {
window.location.reload();
});
FB.Event.subscribe('auth.logout', function(response) {
window.location.reload();
});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>
</body>
</html>
Just use FB.login method of the JavaScript SDK, and call it onclick on your own button.
