Javascript 在Windows8JS应用程序中集成Facebook SDK
我正在尝试开发一个Windows 8应用程序,我想在其中集成Facebook。Javascript 在Windows8JS应用程序中集成Facebook SDK,javascript,windows,facebook,sdk,Javascript,Windows,Facebook,Sdk,我正在尝试开发一个Windows 8应用程序,我想在其中集成Facebook。 我知道这可以在没有SDK的情况下完成,但我看到它也可以用它来完成,我很乐意使用SDK 我已经下载并引用了all.js文件 我在default.html中包含了初始化代码: <div id="fb-root"></div> <script> window.fbAsyncInit = function () { // init the FB JS SDK
我知道这可以在没有SDK的情况下完成,但我看到它也可以用它来完成,我很乐意使用SDK 我已经下载并引用了all.js文件 我在default.html中包含了初始化代码:
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function () {
// init the FB JS SDK
FB.init({
appId: '*******', // App ID from the app dashboard
status: true, // Check Facebook Login status
xfbml: true // Look for social plugins on the page
});
// Additional initialization code such as adding Event Listeners goes here
};

但是,当我单击我附加此功能的按钮时,什么也没有发生。
可能是什么?
感谢您的帮助,
谢谢
Facebook登录示例
//使用来自FB.getLoginStatus()的结果调用此函数。
函数statusChangeCallback(响应){
log('statusChangeCallback');
控制台日志(响应);
//响应对象返回的状态字段允许
//应用程序知道此人的当前登录状态。
//响应对象的完整文档可以在文档中找到
//对于FB.getLoginStatus()。
如果(response.status===“已连接”){
警报(“hh”);
//登录你的应用程序和Facebook。
testAPI();
}else if(response.status===“未授权”){
//此人已登录Facebook,但未登录您的应用程序。
document.getElementById('status')。innerHTML='Please log'+
“进入此应用程序。”;
}否则{
//此人未登录Facebook,因此我们不确定是否
//他们是否登录到此应用程序。
document.getElementById('status')。innerHTML='Please log'+
“进入Facebook。”;
}
}
//当某人完成登录时调用此函数
//按钮。请参见示例中附加到它的onlogin处理程序
//代码如下。
函数checkLoginState(){
FB.getLoginStatus(函数(响应){
状态更改回调(响应);
});
}
window.fbAsyninit=函数(){
FB.init({
appId:'197393374008468',
cookie:true,//启用cookie以允许服务器访问
//会议
xfbml:true,//解析此页面上的社交插件
版本:“v2.7”//使用版本2.2
});
//现在我们已经初始化了SDK,我们调用
//getLoginStatus()。此函数用于获取
//访问此页面的人,可以将三种状态之一返回到
//您提供的回调。它们可以是:
//
//1.登录到您的应用程序(“已连接”)
//2.登录Facebook,但不登录你的应用程序(“未授权”)
//3.未登录Facebook,无法判断是否已登录
//你的应用与否。
//
//这三种情况在回调函数中处理。
