Javascript 你知道为什么facebook connect脚本不起作用吗？

我想将此脚本附加到自定义facebook图标。我有一个javascript：

var fbClicked = false;
FB.init({appId: 'Myappid', status: true, cookie: true, xfbml: true});
function thFBShortCut() {
    FB.login(function(response) {
        fbClicked = true;
        if (response.session && response.perms && fbClicked) {
            window.location = 'http://www.mysite.com/facebookauth/?ref=/';
        }
    }, {perms:'email,publish_stream'});
}
function thFBLogin() {
    fbClicked = true;
    $('.popbox').fadeOut(); 
    FB.getLoginStatus(function(response) {
        if(response.session && response.status == 'connected' && fbClicked) {
            window.location = 'http://www.mysite.com/facebookauth/?ref=/';
        }
    });
}
FB.Event.subscribe('auth.login', function(response) {
    if(response.session && fbClicked){
        window.location = 'http://www.mysite.com/facebookauth/?ref=/';
    }
});

</script>

my html:
<a id="facebookicon" onclick="thFBShortCut()"</a>

(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);
})();
window.fbAsyncInit = function() {
    var fbClicked = false;
    FB.init({appId: 'Myappid', status: true, cookie: true, xfbml: true});

    FB.Event.subscribe('auth.login', function(response) {
        if(response.session && fbClicked){
            window.location = 'http://www.mysite.com/facebookauth/?ref=/';
        }
    });
}
function thFBShortCut() {
    FB.login(function(response) {
        fbClicked = true;
        if (response.session && response.perms && fbClicked) {
            window.location = 'http://www.mysite.com/facebookauth/?ref=/';
        }
    }, {perms:'email,publish_stream'});
}
function thFBLogin() {
    fbClicked = true;
    $('.popbox').fadeOut(); 
    FB.getLoginStatus(function(response) {
        if(response.session && response.status == 'connected' && fbClicked) {
            window.location = 'http://www.mysite.com/facebookauth/?ref=/';
        }
    });
}

var=false；
init（{appId:'Myappid'，status:true，cookie:true，xfbml:true}）；
函数thFBShortCut（）{
FB.登录（功能（响应）{
fbc=true；
if（response.session&&response.perms&&fbClicked）{
window.location=http://www.mysite.com/facebookauth/?ref=/';
}
}，{perms:'email，publish_stream'}）；
}
函数thFBLogin（）{
fbc=true；
$（'.popbox'）.fadeOut（）；
FB.getLoginStatus（函数（响应）{
if（response.session&&response.status=='connected'&&fbClicked）{
window.location=http://www.mysite.com/facebookauth/?ref=/';
}
});
}
FB.Event.subscribe（'auth.login'，函数（响应）{
如果（response.session&&fbClicked）{
window.location=http://www.mysite.com/facebookauth/?ref=/';
}
});
我的html：
您只需要在FB.init（）之前加载Facebook javascript SDK

在

Mihai，我应该在哪里触发脚本？像onclick这样的操作，假设我的id是div=“facebooklogo”，如何在这个图标上启用这个脚本？就像你说的
Login
Mihai，因为它是我在后面添加的wordpress主题
