使用 Angular JS 使卡片动态化

Question

我的 index.js 文件中有这些数据：

angular.module('app', [])
.controller('MainCtrl', function($scope) {
  $scope.demos = [ {
    paragrafo: 'richiesta',
    title:'demo1',
    paragrafo2:'dskjdfdjfdfjkdf',
    link: 'https://www.google.it',
    },
    {
    paragrafo: 'richiesta',
    title:'demo2',
    paragrafo2:'dfhfhfjgfkjghfjkgf',
    link: 'https://www.youtube.it',
    },
    {
    paragrafo: 'richiesta',
    title:'demo3',
    paragrafo2:'sjdsdjddfjdf',
    link: 'https://www.sportmediaset.it',
    },
    {
    paragrafo: 'richiesta',
    title:'demo4',
    paragrafo2:'sdjkdhdkjfhdjfh',
    link: 'https://www.elbocon.pe',
    },
    ];
})
.component('card', {
 templateUrl: 'card.html'
 })

在我的 card.html 组件中，我使用了 ng-repeat，我尝试使用 ng -repeat:

对其进行迭代

<div ng-repeat="demo in demos">
  <div class="card" style="width: 18rem">
    <div class="card-body">
      <p>{{demo.paragrafo}}</p>
      <h5 class="card-title">{{demo.title}}</h5>
      <h6 class="card-subtitle mb-2 text-muted"></h6>
      <p class="card-text">{{demo.paragrafo2}}</p>
      <a class="card-link">{{demo.link}}</a>
    </div>
  </div>
</div>

并且在 index.html 中，我也将组件放在 html 索引中：

<body ng-app="app" ng-cloak>
    <div ng-controller="MainCtrl">
      <div class="container">
        <div class="row">
          <div class="col">
            <card></card>
          </div>
        </div>
      </div>
    </div>
  </body>

但是不行，我想要4张不同数据的卡片出现，谁能帮帮我？

你需要bind your data to the component。此外，访问组件内的数据需要引用 $ctrl.

angular.module('myApp', [])
  .controller('myCtrl', ['$scope', function($scope) {
    $scope.demos = [{
        paragrafo: 'richiesta',
        title: 'demo1',
        paragrafo2: 'dskjdfdjfdfjkdf',
        link: 'https://www.google.it',
      },
      {
        paragrafo: 'richiesta',
        title: 'demo2',
        paragrafo2: 'dfhfhfjgfkjghfjkgf',
        link: 'https://www.youtube.it',
      },
      {
        paragrafo: 'richiesta',
        title: 'demo3',
        paragrafo2: 'sjdsdjddfjdf',
        link: 'https://www.sportmediaset.it',
      },
      {
        paragrafo: 'richiesta',
        title: 'demo4',
        paragrafo2: 'sdjkdhdkjfhdjfh',
        link: 'https://www.elbocon.pe',
      },
    ];
  }])
  .component('card', {
    bindings: {
      demo: '<'
    },
    template: '<div class="card" style="width: 18rem"><div class="card-body"><p>{{$ctrl.demo.paragrafo}}</p><h5 class="card-title">{{$ctrl.demo.title}}</h5><h6 class="card-subtitle mb-2 text-muted"></h6><p class="card-text">{{$ctrl.demo.paragrafo2}}</p><a class="card-link">{{$ctrl.demo.link}}</a></div></div>'
  })

<script src="https://cdnjs.cloudflare.com/ajax/libs/angular.js/1.7.5/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
  <card demo="data" ng-repeat="data in demos">
  </card>
</div>
