AngularJS: 如何更新 $scope 属性

AngularJS: How can I update the $scope property

我在 $scope 上有一个对象,它指示 "next screen" 应用程序在更新后运行(我处于类似向导的多屏幕新表单中)并且在显示每个屏幕时,我想在边栏中显示当前和所有后续屏幕 -- 便于用户返回以进行更改,但不允许 him/her 通过不显示未来屏幕来跳过步骤。

当然,它必须是动态的,因为不同类型的贷款屏幕顺序会发生变化。

我的问题 -- 在当前屏幕的控制器中,如何将状态更改为 true 并使视图识别更改? (LoDash 可用)

这是 $scope.screens(对象数组)的一部分:

[
  {
    "id": 13,
    "loantype_id": 2,
    "screen": "farmer",
    "label": "Farmer",
    "sort_order": 1,
    "status": 1
  },
  {
    "id": 14,
    "loantype_id": 2,
    "screen": "applicant",
    "label": "Applicant",
    "sort_order": 2,
    "status": 0
  },
  {
    "id": 15,
    "loantype_id": 2,
    "screen": "quests",
    "label": "Questions",
    "sort_order": 3,
    "status": 0
  },
  {
    "id": 16,
    "loantype_id": 2,
    "screen": "references",
    "label": "References",
    "sort_order": 4,
    "status": 0
  }
]

我从农民屏幕转到申请人屏幕,我可以从状态 URL 提醒 "applicant" -- 该值应该可以用于 "find" $scope.screens 中的正确对象,但我无法弄清楚

这是 ApplicantController 的相关部分 -- alert(currScreen) == 'applicant':

(function(){
    'use strict';
    angular
      .module('ARM')
      .controller('NewApplicantController', function(
        $scope, $state, $stateParams, Loan,
        AppFactory, ApplicantsFactory
      ){
        var curr = $state.current.url;
        var currScreen = curr.substring(1,curr.length);
        alert(currScreen);

        $scope.loan = Loan.data.data[0];

        if($scope.loan.applicant_id) {
          ApplicantsFactory.getApplicant($scope.loan.applicant_id)
            .then(function success(rsp) {
              $scope.applicant = rsp.data.data;
              $scope.applicant.entity_type_id = '2';
            });
        } else {
          $scope.applicant = { entity_type_id: '2' };
        } // end if

        $scope.createApplicant = function() {
          ApplicantsFactory.createApplicant($scope.applicant)
            .then(function(rsp){
              AppFactory.patchIt('/loans/', $stateParams.loanID, {applicant_id: rsp.data.message});
              AppFactory.moveToNextNewLoanScreen(currScreen, $stateParams);
            });
        };
      });
})();

可能是因为根据您上面引用的屏幕数组,'currScreen' 未定义?我的意思是“$scope.screens[0].currScreen”不存在,因此您不能分配“$scope.screens[0].currScreen.status = 1”。
