我有以下代碼但FB.login給出了FB未定義的javascript錯誤。FB未在Facebook中定義登錄
我錯過了什麼?
<html>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function()
{
FB.init
({
appId : 'XXXX',
status : true,
cookie : true,
xfbml : true
});
};
(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);
}());
FB.login(function(response)
{
if(response.session)
{
if(response.perms)
{
alert('yippee');
}
else
{
alert('oh no');
}
}
else
{
alert('login silly');
}
}, {perms:'email,user_birthday'});
</script>
hello
<fb:login-button></fb:login>
</body>
</html>
