Question

我是AngularJS的新手，此时仍然在玩它。为了自学这些概念，我正在处理一些手工构建的JSON文件。

我首先使用它来构建弹出式javascript菜单的元素，在控制器访问JSON文件的列表元素上使用ng-repeat。这工作得很好。然后我尝试在一个不同的JSON文件上重复一个相当复杂的表行结构，并使用稍微复杂的数据模型。在运行时，这会返回一个注释，就像上一个实验一样，但没有元素可以与它一起使用。

我使用两个控制器作为一个应用程序的一部分。我认为问题可能在于如何访问JSON文件中的数据。

不包括CSS，因为我不会认为会影响它。＆＃39; MenuCtrl＆＃39;控制器仍然正常运行（在整个页面的元素上调用ng-app），所以我只包括我认为的相关HTML。

controllers.js：

  var profileApp = angular.module('profileApp', []);
  profileApp.controller('BookCtrl', function ($scope, $http){
    $http.get('books.json').success(function(data) {
      $scope.bookItems = data;
    });
  });
  profileApp.controller('MenuCtrl', function ($scope, $http){
    $http.get('profile.json').success(function(data) {
      $scope.profileItems = data;
    });
  });

books.json：

HTML的相关部分：

<div  align="center">
<p class="central">Bibliography</br></p></br>
<table class="content1" ng-controller="BookCtrl" >
    <colgroup>
        <col span="1" class="col1">
        <col span="1.5" class="col2">
    </colgroup>
    <tbody ng-repeat="book in bookItems" >
    <tr >
        <td align="center"><div class="center"><div class="round3"><a href=""><img class="book" ng-src="{{book.img}}"></img></a></div></div></td>
        <td></td>
        <td class="wrapword" style="padding-left:10px;"><p><span class="content2"><strong>{{book.title}}</strong></span>
            <span class="small2">{{book.author}}</br>
            <span class="hide2" id="{{book.id1}"}>See Description</span>
            <span class="hide" id="{{book.id2}}">{{book.description}}</span>
            </span>
        </p></td>
    </tr>
    </tbody>
</table>
</div>

检查正在运行的页面的元素时得到的结果：

<table class="content1 ng-scope" ng-controller="BookCtrl">
    <colgroup>
        <col span="1" class="col1">
        <col span="1.5" class="col2">
    </colgroup>
    <!-- ngRepeat: book in bookItems -->
</table>

Answer 1

你已经提到过TBODY中的ng-repeat，我更正了。这应该现在有效。

<div  align="center">
<p class="central">Bibliography</br></p></br>
<table class="content1" ng-controller="BookCtrl" >
    <colgroup>
        <col span="1" class="col1">
        <col span="1.5" class="col2">
    </colgroup>
    <tbody  >
    <tr ng-repeat="book in bookItems">
        <td align="center"><div class="center"><div class="round3"><a href=""><img class="book" ng-src="{{book.img}}"></img></a></div></div></td>
        <td></td>
        <td class="wrapword" style="padding-left:10px;"><p><span class="content2"><strong>{{book.title}}</strong></span>
            <span class="small2">{{book.author}}</br>
            <span class="hide2" id="{{book.id1}"}>See Description</span>
            <span class="hide" id="{{book.id2}}">{{book.description}}</span>
            </span>
        </p></td>
    </tr>
    </tbody>
</table>
</div>

Answer 2

好的，我发现某些标记无效但我认为您的代码因为标记无效而中断：<span class="hide2" id="{{book.id1}"}>See Description</span>，更改为<span class="hide2" id="{{book.id1}}">See Description</span>

Ng-Repeat不重复（或返回任何内容）
