我想通过使用“ng-repeat”和“ng-controller”显示所有评论元素，如列表，但我不知道如何在菜中显示评论元素！像这样：

笔记：

由于dish是一个数组，按照惯例，它应该是复数的，所以我做到了。

如果您只想在第一道菜的评论中进行迭代，它可以：

var app = angular.module('confusionApp', []);

app.controller('dishDetailController', function() {
  this.filtText = '';
  var dishes = [{
    name: 'Uthapizza',
    image: 'images/uthapizza.png',
    category: 'mains',
    lable: 'Hot',
    price: '4.99',
    description: 'A unique combination of Indian Uthappam (pancake) and Italian pizza, topped with Cerignola olives, ripe vine cherry tomatoes, Vidalia onion, Guntur chillies and Buffalo Paneer.',
    comments: [{

        comment: "Imagine all the eatables, living in conFusion!",
        author: "John Lemon",
        date: "2012-10-16T17:57:28.556094Z"
      }, {
        rating: 4,
        comment: "Sends anyone to heaven, I wish I could get my mother-in-law to eat it!",
        author: "Paul McVites",
        date: "2014-09-05T17:57:28.556094Z"
      }, {
        rating: 3,
        comment: "Eat it, just eat it!",
        author: "Michael Jaikishan",
        date: "2015-02-13T17:57:28.556094Z"
      }, {
        rating: 4,
        comment: "Ultimate, Reaching for the stars!",
        author: "Ringo Starry",
        date: "2013-12-02T17:57:28.556094Z"
      }, {
        rating: 2,
        comment: "It's your birthday, we're gonna party!",
        author: "25 Cent",
        date: "2011-12-02T17:57:28.556094Z"
      }
    ]
  }];

  this.dishes = dishes;
});

但是您也可以使用特殊的重复次数来迭代所有菜肴，如下所示：

var app = angular.module('confusionApp', []);

app.controller('dishDetailController', function() {
  this.filtText = '';
  var dishes = [{
    name: 'Uthapizza',
    image: 'images/uthapizza.png',
    category: 'mains',
    lable: 'Hot',
    price: '4.99',
    description: 'A unique combination of Indian Uthappam (pancake) and Italian pizza, topped with Cerignola olives, ripe vine cherry tomatoes, Vidalia onion, Guntur chillies and Buffalo Paneer.',

      }, {
        rating: 4,
        comment: "Sends anyone to heaven, I wish I could get my mother-in-law to eat it!",

        author: "Michael Jaikishan",

      }, {

      }, {

        comment: "It's your birthday, we're gonna party!",
        author: "25 Cent",
        date: "2011-12-02T17:57:28.556094Z"
      }
    ]
  }];

  this.dishes = dishes;
});

这是一个简单的 HTML，仅当您的菜数组包含 1 个元素时才有效。如果它包含多个元素，您可以简单地遍历它

HTML

<html ng-app="confusionApp">
<body>
    <div ng-controller="dishDetailController">
        <ul ng-repeat="c in dish[0].comments">
            <li>{{c.rating}} stars</li>
            <li>{{c.comment}}</li>
            <li>{{c.author}}, {{c.date | date: 'mediumDate' }}</li>
        </ul>
    </div>
</body>
</html>

您可以<ul>通过任何其他标签更改标签以微调您要查找的内容
