javascript - 使用电子邮件和密码错误验证用户身份

Question

我正在尝试为 firebase 创建邮件和密码用户，但我一直收到此错误:

Error: The browser redirected the page before the login request could complete. {code: "REQUEST_INTERRUPTED", stack: (...), message: "The browser redirected the page before the login request could complete."}

var ref = new Firebase("https://***.firebaseio.com");
$('.btn').click(function() {
   var mail = $('#inputEmail3').val();
   var pass = $('#inputPassword3').val();
   ref.createUser({
       email : mail,
       password : pass
    }, function(error) {
       if (error === null) {
        console.log("User created successfully");
       } else {
        console.log("Error creating user:", error);
       }
   });
});

$(document).ready();

如果您使用 $('.btn') 选择器选择的元素是一个链接，则浏览器将在异步 ref.createUser 之前导航到链接页面功能完成。为了防止这种情况发生，请在点击事件处理程序的末尾添加一个 return false 语句。您还可以在点击处理程序顶部添加 e.preventDefault() 语句，这将确保不会发生链接导航，如下所示。

$('.btn').click(function(e) { //Add the 'e' event object to the parameters
    e.preventDefault() //Prevents navigation (the default link click action)
    var mail = $('#inputEmail3').val();
    var pass = $('#inputPassword3').val();
    ref.createUser({
        email : mail,
        password : pass
    }, function(error) {
       if (error === null) {
        console.log("User created successfully");
       } else {
        console.log("Error creating user:", error);
       }
   });
   return false; //Extra insurance
});
