我需要幫助。我不知道如何檢測 phoneNumber 是否已成功鏈接到用戶。如果操作成功，我想重定向到其他頁面。我的代碼是這樣的。*我的代碼有效，但如果我添加一個(gè)函數(shù)來重定向它不起作用。function verifyNumber(){var user = firebase.auth().currentUser;var phoneNumber = document.getElementById('phoneNumber');var signInButtonElement = document.getElementById('sign-in-button');var inputCode = document.getElementById('code');var codeButton = document.getElementById('confirm-code');if(!user.phoneNumber){  // You also need to provide a button element signInButtonElement  // which the user would click to complete sign-in.  // Get recaptcha token. Let's use invisible recaptcha and hook to the button.  var appVerifier = new firebase.auth.RecaptchaVerifier(      signInButtonElement, {size: 'invisible'});  // This will wait for the button to be clicked the reCAPTCHA resolved.  user.linkWithPhoneNumber(phoneNumber.value, appVerifier)    .then(function(confirmationResult) {      // Ask user to provide the SMS code.      phoneNumber.style.display = 'none';      signInButtonElement.style.display = 'none';      //inputCode.style.display = 'inline-block'      //codeButton.style.display = 'inline-block'       var code = window.prompt('Provide your SMS code');      // Complete sign-in.      return confirmationResult.confirm(code);      //updateStatus() doesnt work    });    } } function updateStatus(){ var user = firebase.auth().currentUser; if(user.phoneNumber){    window.location.href = "../home/home.html"; }else{    alert('Ha ocurrido un error'); } }
