下面的代码在设置为名为 onclick 的函数时有效
<script type="text/javascript">
function Nome_evento() {
FB.api("/1718063768425398",
function (response) {
if (response && !response.error) {
/* handle the result */
document.getElementById("evento").innerHTML = response.name;
}
});
}
</script>但是当
<script type="text/javascript">
FB.api("/1718063768425398",
function (response) {
if (response && !response.error) {
/* handle the result */
document.getElementById("evento").innerHTML = response.name;
}
});
</script>下面是完整的 html 以供进一步了解
<html>

FB.Event.subscribe('auth.authResponseChange', function (response) {
if (response.status === 'connected') {
alert("Successfully connected to Facebook!");
}
else if (response.status === 'not_authorized') {
alert("Login failed!");
} else {
alert("Unknown error!");
}
});
</script>

</html>--编辑这是face_init_js.js，FB功能(如登录)正在工作
window.fbAsyncInit = function () {
FB.init({
appId: '*****************',
status: true,
cookie: true,
xfbml: true,
version : 'v2.5'
});
};
(function(d, s, id){
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) {return;}
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));2 编辑 -
<script type="text/javascript">
window.fbAsyncInit = function () {
FB.init({
appId: '505610319610868',
status: true,
cookie: true,
xfbml: true,
version : 'v2.5'
});
FB.api("/1718063768425398",
function (response) {
if (response && !response.error) {
/* handle the result */
document.getElementById("evento").innerHTML = response.name;
}
});
};
</script>最佳答案
只有在加载并初始化JavaScript SDK后才能使用它:
window.fbAsyncInit = function() {
//SDK loaded, initialize it
FB.init({
appId : 'your-app-id',
xfbml : true,
version : 'v2.5'
});
//now you can use FB
};

如果这对您没有帮助，并且当您尝试使用 FB 时浏览器控制台中没有错误，请将 console.log 放在回调函数的开头。换句话说:调试您的代码。
