我想知道你们中的一些人是否可以减轻我的负担并尝试解释我在此错过了什么：http://plnkr.co/edit/opxB2Jfi0Xf0Tq1780vz?p=preview

对我来说看起来很简单，但不起作用。我的代码：

<section ng-app="myApp">
<div ng-controller="myCtrl">
    <ul ng-init="tab=1">
        <li ng-repeat="item in data">
          <a href ng-click="tab = item.thingy">{{item.name}}</a>
        </li>
    </ul>
    <div ng-repeat="item in data" ng-show="tab === item.thingy">
        <img ng-src="{{item.img}}" width="50px"><br>
        {{item.year}}</div>
</div>
</section>

<script>
var app = angular.module('myApp', []);

app.controller('myCtrl', ['$scope',
function($scope) {
$scope.data = [{
  name: "First",
  title: "oneTitle",
  description: "Lorem ipsum dolor sit amet, consectetur adipiscing elit.",
  year: "2013",
  img: "http://static.hdw.eweb4.com/media/wp_400/1/5/42735.jpg",
  thingy: 1
}, {
  name: "third",
  title: "twoTitle",
  description: "Quisque pulvinar libero sed eros ornare",
  year: "2014",
  img: "http://static.hdw.eweb4.com/media/wp_400/1/1/8519.jpg",
  thingy: 2
}, {
  name: "Second",
  title: "threeTitle",
  description: "Cras accumsan massa vitae tortor vehicula .",
  year: "2015",
  img: "http://static.hdw.eweb4.com/media/wp_400/1/5/43326.jpg",
  thingy: 3
}, {
  name: "fourth",
  title: "FourTitle",
  description: "Suspendisse vitae mattis magna.",
  year: "2011",
  img: "http://static.hdw.eweb4.com/media/wp_400/1/5/42413.jpg",
  thingy: 4
 }];

}
]);


</script>

提前谢谢你！

【解决方案1】：

script.js 中的修改：

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

app.controller('myCtrl', ['$scope', function ($scope) {
    $scope.data = [{
        name: "First",
        title: "oneTitle",
        description: "Lorem ipsum dolor sit amet, consectetur adipiscing elit.",
        year: "2013",
        img: "http://static.hdw.eweb4.com/media/wp_400/1/5/42735.jpg",
        thingy: 1
    }, {
        name: "third",
        title: "twoTitle",
        description: "Quisque pulvinar libero sed eros ornare",
        year: "2014",
        img: "http://static.hdw.eweb4.com/media/wp_400/1/1/8519.jpg",
        thingy: 2
    }, {
        name: "Second",
        title: "threeTitle",
        description: "Cras accumsan massa vitae tortor vehicula .",
        year: "2015",
        img: "http://static.hdw.eweb4.com/media/wp_400/1/5/43326.jpg",
        thingy: 3
    }, {
        name: "fourth",
        title: "FourTitle",
        description: "Suspendisse vitae mattis magna.",
        year: "2011",
        img: "http://static.hdw.eweb4.com/media/wp_400/1/5/42413.jpg",
        thingy: 4
    }];

  $scope.details = $scope.data[0];

  $scope.GetDetails = function(obj)
  {
    $scope.details = obj;
  }

}]
);

在 HTML 中：

<section ng-app="myApp">
<div ng-controller="myCtrl">
        <ul ng-init="tab=1">
            <li ng-repeat="item in data">
              <a href ng-click="GetDetails(item);">{{item.name}}</a>
            </li>
        </ul>
        <div>
          {{details.thingy}} <br/>
          {{details.name}}<br/>
          {{details.title}}<br/>
          {{details.description}}<br/>
          {{details.year}}<br/>
          <img ng-src="{{details.img}}" width="50px"><br>
        </div>
</div>
</section>

基本上不需要第二次 ng-repeat
