Question

我有一个小型投资组合项目我试图使用Angular构建，我使用ng-repeat重复了我的投资组合中的项目。但我只想要展示1个（第一个）项目。我在侧边栏中有一个小导航，我希望能够点击项目中的项目。我对Angular来说是全新的，但到目前为止，我已经阅读了路由和模板，但我不想使用外部html文件。任何建议都非常感谢！

使用Javascript：

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

var pageContent = [
    {
        displayOrder: 1,
        name: 'Project 1',
        description: "Some description",
        images: ["img/portfolio/feat_image_1.jpg"]
    },
    {
        displayOrder: 2,
        name: 'Project 2',
        description: "A second description",
        images: ["img/portfolio/feat_image_2.jpg"]
    },
    {
        displayOrder: 3,
        name: 'Project 3',
        description: "A third description",
        images: ["img/portfolio/feat_image_3.jpg"]
    }
];

app.controller("portfolioController", function($scope) {
    this.projects = pageContent;
});

HTML：

<div ng-controller="portfolioController as myPortfolio">

<!-- various html page header etc. --> 

  <div class="row" ng-repeat="project in myPortfolio.projects">

      <div class="large-2 columns" id="sidebar">
        <h1>{{project.name}}</h1>
        <p>{{project.description}}</p>
        <div class="row side-nav-div">
          <div class="large-4 columns project-nav">
            <button type="button" class="slick-prev slick-disabled left">Previous</button>
          </div>
          <div class="large-4 columns project-nav centered">
          </div>
          <div class="large-4 columns project-nav">
            <button type="button" class="slick-next slick-disabled right" ng-click="">Next</button>
          </div>
          <div style="clear:both"></div>
        </div>
      </div>
      <div class="large-10 columns" id="main-section">
        <div class="slider1">
          <div class="feature-img" ng-repeat="image in project.images">
             <img ng-src="{{image}}"/>
          </div>
        </div>
      </div>

  </div>
</div>

最简单的解决方案：

app.controller("portfolioController", function($scope) {
    $scope.projects = [
    {
        displayOrder: 1,
        name: 'Project 1',
        description: "Some description",
        images: ["img/portfolio/feat_image_1.jpg"]
    },
    {
        displayOrder: 2,
        name: 'Project 2',
        description: "A second description",
        images: ["img/portfolio/feat_image_2.jpg"]
    },
    {
        displayOrder: 3,
        name: 'Project 3',
        description: "A third description",
        images: ["img/portfolio/feat_image_3.jpg"]
    }
    ];

    $scope.activeProject=0;

});

你的HTML

<div ng-controller="portfolioController as myPortfolio">

<ul><li ng-repeat="project in myPortfolio.projects" ng-click="$parent.activeProject=$index">{{project.name}}</li></ul>
<!-- various html page header etc. --> 

  <div class="row" ng-repeat="project in myPortfolio.projects" ng-show="$index==$parent.activeProject">

      <div class="large-2 columns" id="sidebar">
        <h1>{{project.name}}</h1>
        <p>{{project.description}}</p>
        <div class="row side-nav-div">
          <div class="large-4 columns project-nav">
            <button type="button" class="slick-prev slick-disabled left" ng-disabled="$index==0" ng-click="activeProject=$index-1">Previous</button>
          </div>
          <div class="large-4 columns project-nav centered">
          </div>
          <div class="large-4 columns project-nav">
            <button type="button" class="slick-next slick-disabled right"  ng-disabled="$index==(myPortfolio.projects.length-1)" ng-click="activeProject=$index+1">Next</button>
          </div>
          <div style="clear:both"></div>
        </div>
      </div>
      <div class="large-10 columns" id="main-section">
        <div class="slider1">
          <div class="feature-img" ng-repeat="image in project.images">
             <img ng-src="{{image}}"/>
          </div>
        </div>
      </div>
  </div>
</div>

注意在项目详细信息列表中添加了activeProject变量，ng-show以及用于选择项目的项目名称的菜单

Angular.js点击json数据数组？
