Question

这似乎应该是如此简单，但我的大脑正在爆炸。这是我想用角度来实现的，我有我的购物清单

app.controller("Destroyer", function($scope) {
    $scope.shoppingList = [
      {name: 'Milk'},
      {name: 'Eggs'},
      {name: 'Bread'},
      {name: 'Cheese'},
      {name: 'Ham'}
    ];

});

在我的模板中，我想访问第3项，例如

{{ shoppingList.name[$index == 2] }}

我该怎么做？感谢

编辑：回答{{shoppingList [2] .name}}

Answer 1

if you know the index you can give like this

{{shoppingList[2].name}}

or in ng-repeat 

<div ng-repeat="list in shoppingList " ng-show="$index==2">{{list.name}}</div>

如何使用$ index（angular）访问数组中的特定项
