我的index.js檔案中有這些資料：
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組件中，我使用了 ng-repeat，我嘗試使用 ng -repeat 對其進行迭代：
<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>
在index.html中，我也將組件放入 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>
但它不起作用，我想出現4張不同資料的卡片，有人可以幫我嗎？
uj5u.com熱心網友回復：
您需要將資料系結到組件。此外，訪問組件內部的資料需要參考 $ctrl。
angular.module('myApp', [])
.controller('myCtrl', ['$scope', function($scope) {
$scope.demos = [{
paragrafo: 'richiesta',
title: 'demo1',
paragrafo2: 'dskjdfdjfdfjkdf',
link: 'https://www.google.it',
},
{
paragrafo: 'richiesta',
title: 'demo2',
paragrafo2: 'dfhfhfjgfkjghfjkgf',
link: 'https://www.youtube.it',
},
{
paragrafo: 'richiesta',
title: 'demo3',
paragrafo2: 'sjdsdjddfjdf',
link: 'https://www.sportmediaset.it',
},
{
paragrafo: 'richiesta',
title: 'demo4',
paragrafo2: 'sdjkdhdkjfhdjfh',
link: 'https://www.elbocon.pe',
},
];
}])
.component('card', {
bindings: {
demo: '<'
},
template: '<div style="width: 18rem"><div ><p>{{$ctrl.demo.paragrafo}}</p><h5 >{{$ctrl.demo.title}}</h5><h6 ></h6><p >{{$ctrl.demo.paragrafo2}}</p><a >{{$ctrl.demo.link}}</a></div></div>'
