问题描述
我试图让这个事件FB订阅事件被解雇（警告（'hi'））但它似乎不起作用：
I am trying to get this event FB Subscribe event fired (alert('hi')) but it does not seem to work though:
<!doctype html>
<html lang="en" xmlns:fb="https://www.facebook.com/2008/fbml">
<head>
<meta charset="utf-8">
<title>Facebook Like Button</title>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function () {
FB.init({ appId: 'myappid', status: true, cookie: true, xfbml: true });
targetUrl="http://www.goal.com";
FB.Event.subscribe("xfbml.render", function () {
console.log('xfbml.render');
FB.Event.subscribe("edge.create", function (targetUrl) {
console.log('edge.create');
alert('hi');
});
FB.Event.subscribe("edge.remove", function (targetUrl) {
console.log('edge.remove');
});
});
};
(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>
<fb:like></fb:like>
</body>
</html>
推荐答案
我注意到edge.create事件不是'在localhost上触发。上传到Facebook可见的测试服务器后，它运行良好。
I've noticed that edge.create event isn't fired on localhost. After uploading to test server which is visible by Facebook, it worked.
另外，正如Rufinus建议的那样，订阅xfbml.render回调函数之外的那些事件。
Also, As Rufinus suggested, subscribe to those events outside of xfbml.render callback function.
<script>
window.fbAsyncInit = function () {
FB.init({ appId: 'myappid', status: true, cookie: true, xfbml: true });
targetUrl="http://www.goal.com";
FB.Event.subscribe("xfbml.render", function () {
console.log('xfbml.render');
});
FB.Event.subscribe("edge.create", function (targetUrl) {
console.log('edge.create');
alert('hi');
});
FB.Event.subscribe("edge.remove", function (targetUrl) {
console.log('edge.remove');
});
};
(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>
