Question

我尝试更新用户个人资料，然后阅读this documentation。但是，为什么我无法改变我的displayName？它总是给我null。

它也给了我TypeError: userNow is null。

我应该遵循哪一个更新/编辑用户个人资料？

将代码从var userNow = firebase.auth().currentUser;开始包含在函数中。正如@Andre Kool所说，你需要首先确定你是否正确（因为它是异步操作然后尝试更新用户数据：

    var authRef = firebase.auth();
    authRef.onAuthStateChanged(function(user) {
        if (user) {
            console.log('Display name onAuthStateChanged : '+user.displayName);
            _updateUserData();
        } else {
            console.log('not login');
        }
    });

    fucntion _updateUserData(){
      var userNow = firebase.auth().currentUser;
        userNow.updateProfile({
        displayName: "Jane Q. User",
        photoURL: "https://example.com/jane-q-user/profile.jpg"
      }).then(function() {
        var displayName = userNow.displayName;
        var photoURL = userNow.photoURL;
      }, function(error) {

      });
  }
