ng-repeat 用于由变量表示的数组

Question

我正在尝试使用 ng-repeat 来显示数组。根据变量的值，数组 ng-repeat 循环应该改变。

这是我到目前为止所做的（没有用）

HTML

<body ng-app="myApp" ng-controller="myCtrl">

<h1 ng-repeat="x in selection">{{x}}</h1>

JS

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.records1 = [
    "Apple",
    "Orange",
    "Banana",
    "Mango",
  ];
  $scope.records2 = [
     "Lion",
     "Tiger",
     "Crocodile",
     "Olephant"
  ];
  $scope.selection = records1;

});

我做错了什么，正确的方法是什么？

我认为你应该这样做：

JS

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.records1 = [
    "Apple",
    "Orange",
    "Banana",
    "Mango",
  ];
  $scope.records2 = [
     "Lion",
     "Tiger",
     "Crocodile",
     "Olephant"
  ];
  $scope.selection = $scope.records1;

});
