在多个页面上保持联系

由 发布于

我无法让用户帐户在多个页面上保持连接状态，我想做的是，当用户进行身份验证时，他将被重定向到加载了数据的另一个页面，但是我不能这样做，因为他们没有上传到其他页面。

data is not loaded: enter image description here

我的代码js：

var authEmailPassButton = document.getElementById('authEmailPassButton') 
var logOutButton = document.getElementById('logOutButton')
var emailInput = document.getElementById('emailInput')
var passwordInput = document.getElementById('passwordInput')


authEmailPassButton.addEventListener('click', function(){
    firebase
    .auth()
    .signInWithEmailAndPassword(emailInput.value, passwordInput.value)
    .then(function(result){
        console.log(result)
        alert('Welcome')
    })
.catch(function (error){
    console.error(error.code)
    console.error(erro.message)
    alert('Failed to authenticate, check the console for the error!')
})
})

firebase.auth().onAuthStateChanged(function(user){
if (user) {

    var user = firebase.auth().currentUser;

     if (user != null) {
        var email = user.email;
        var emailVerified = user.emailVerified;
        var uid = user.uid
        displayName.innerText = 'Welcome, ' + email
        window.location = 'home.html'
    }         

} else {
    console.log('Not connected')
}
})


 logOutButton.addEventListener('click', function(){
firebase
.auth().signOut()
.then(function (){
        alert('You disconnected')
}, function(error){
        console.error(error)
    })
})

我不知道为什么会这样！
