AngularJS我想要<code>userName</code>相同<code>email</code>對象

Question

也許愚蠢的問題，但

$scope.registration = { 
     email: "", 
     userName: "", 
     password: "", 
     confirmPassword: "", 
     firstName: "DummyFirstName", 
     lastName: "DummyLastName" 
    }; 

中的一個字段的值設置爲另一個領域。

我想這樣的：

$scope.registration = { 
     email: "", 
     userName: email, 
     password: "", 
     confirmPassword: "", 
     firstName: "DummyFirstName", 
     lastName: "DummyLastName" 
    }; 

，但我得到的不存在的錯誤。

你可以這樣做：

$scope.registration = { 
    email: "", 
    password: "", 
    confirmPassword: "", 
    firstName: "DummyFirstName", 
    lastName: "DummyLastName" 
}; 
$scope.registration.userName = $scope.registration.email;
