Web中的Firebase：发生网络错误（例如超时，连接中断或主机不可达）？

Question

firebase.auth().onAuthStateChanged(function(user) {
  if (user) {
    // User is signed in.
      console.log("Hurray ! signed in successfully !");
  } else {
    // No user is signed in.
     console.log("Sign in required !");
     $("#login-btn-nav").click();
  }
});



$("#login-btn").on('click',function(){
    console.log("Hello");
    var email = $("#email-input").val();
    var password = $("#password-input").val();

    if(email != "" && password != ""){
    		firebase.auth().signInWithEmailAndPassword(email, password).catch(function(error) {
				  // Handle Errors here.
				  var errorCode = error.code;
				  var errorMessage = error.message;
				  // ...
				  window.alert("Following error encountered : "+errorMessage+" .");
				});
    		}
});
