我有问题,我的Facebook登录按钮在Firefox和移动设备等浏览器中不起作用,结果显示未定义javascript错误fb我尝试修复多次,阅读了许多博客,但均失败,有人可以排序我的代码中的问题是我在视图中添加的脚本。错误在脚本的最后一行
<script>
// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {
console.log(response);
if (response.status === 'connected') {
testAPI();
} else {
// The person is not logged into your app or we are unable to tell.
}
}
// This function is called when someone finishes with the Login
// Button. See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}
window.fbAsyncInit = function() {
FB.init({
appId : '***********************',
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : 'v3.1' // use graph api version 2.8
});
// Now that we've initialized the JavaScript SDK, we call
// FB.getLoginStatus(). This function gets the state of the
// person visiting this page and can return one of three states to
// the callback you provide. They can be:
//
// 1. Logged into your app ('connected')
// 2. Logged into Facebook, but not your app ('not_authorized')
// 3. Not logged into Facebook and can't tell if they are logged into
// your app or not.
//
// These three cases are handled in the callback function.
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
};
// Load the SDK asynchronously
