Question

这是嵌套数组的结构：

$scope.History = [
        {
            isCustomer:false,
            userText:"some text",
            options:[]            
        }

包含数据的数组： // DisplayLabel中的文本对于所有对象都是相同的。

$scope.Categories = [
   { "QuestionId": 1, "QuestionName": "Complaint", "DisplayLabel": "what is it?" },
   { "QuestionId": 2, "QuestionName": "Registration", "DisplayLabel": "what is it?" }        
            ];

所需数组：

$scope.History = [
        {
            isCustomer:false,
            userText:"what is it?",
            options:["Complaint","Registration"]            
        }

通常我会为1D数组执行此操作

angular.forEach($scope.Categories, function (value, key) {
$scope.History.push(false,value.DisplayLabel);

现在，如何将商品添加到＆＃39;选项＆＃39;对象。

修改我试过这个，但没有运气。不显示任何数据

var optionsData = [];
var userText = "";
angular.forEach($scope.Categories, function (value, key) {
optionsData.push(value.QuestionName);
userText = value.DisplayLabel;
        })
        $scope.History.push(false,userText,optionsData);

var app = angular.module('app', []);

app.controller('homeCtrl', function($scope) {

  $scope.History = [{
    isCustomer: false,
    userText: "some text",
    options: []
  }]

  $scope.Categories = [{
    "QuestionId": 1,
    "QuestionName": "Complaint",
    "DisplayLabel": "what is it?"
  }, {
    "QuestionId": 2,
    "QuestionName": "Registration",
    "DisplayLabel": "what is it?"
  }];
  var optionsData = []

  angular.forEach($scope.Categories, function(value, key) {


    $scope.History[0].options.push(value.QuestionName)
  });




});
