Javascript 无法设置子对象的未定义属性

当我尝试为父对象物理的子对象addressline_1赋值时，我得到一个“无法设置未定义的addressline_1属性”。如果有人能告诉我如何解决此问题，我将不胜感激。谢谢

$scope.editCompany = function(){
  $scope.submitCompany =[{phone:[]}]; 
  $scope.submitCompany[0].name = "Some Company";
  $scope.submitCompany[0].email = "company@example.com";
  $scope.submitCompany[0].is_active = "TRUE";
  $scope.submitCompany[0].physical.addressline_1 = "77 Example rd";
}

我也尝试过以下方法，但没有成功

$scope.editCompany = function(){
  $scope.submitCompany =[{phone:[]},{physical:{addressline_1:"",addressline_2:"",addressline_3:"",addressline_4:"",city:"", region:"",country:"", post_code:""}}]; 
  $scope.submitCompany[0].name = "Some Company";
  $scope.submitCompany[0].email = "company@example.com";
  $scope.submitCompany[0].is_active = "TRUE";
  $scope.submitCompany[0].physical.addressline_1 = "77 Example rd";
}

在尝试设置对象的属性之前，需要先创建物理对象：

$scope.editCompany = function(){
  $scope.submitCompany =[{phone:[]}]; 
  $scope.submitCompany[0].name = "Some Company";
  $scope.submitCompany[0].email = "company@example.com";
  $scope.submitCompany[0].is_active = "TRUE";
  $scope.submitCompany[0].physical = {};
  $scope.submitCompany[0].physical.addressline_1 = "77 Example rd";
};

或相同的更清晰语法：

$scope.editCompany = function () {
    $scope.submitCompany = [{
        phone: [],
        name: "Some Company",
        email: "company@example.com",
        is_active: "TRUE",
        physical: {
            addressline_1: "77 Example rd"
        }
    }];
};

在设置属性之前，将对象分配给

物理

属性是正确的，但您将其放在

$scope.submitCompany[1]。物理
而不是
$scope.submitCompany[0]。物理

将
物理
属性与
电话
属性放在同一对象中：

$scope.editCompany = function(){
  $scope.submitCompany = [ { phone: [], physical: {} } ]; 
  $scope.submitCompany[0].name = "Some Company";
  $scope.submitCompany[0].email = "company@example.com";
  $scope.submitCompany[0].is_active = "TRUE";
  $scope.submitCompany[0].physical.addressline_1 = "77 Example rd";
}

只要找点零钱就行了

$scope.editCompany = function(){
  $scope.submitCompany =[{phone:[]},{physical:{addressline_1:"",addressline_2:"",addressline_3:"",addressline_4:"",city:"", region:"",country:"", post_code:""}}]; 
 ....
  $scope.submitCompany[1].physical.addressline_1 = "77 Example rd"; // instead $scope.submitCompany[0].physical.addressline_1
}
