Angular 中的面包屑 [英] Breadcrumbs in Angular

问题描述

我想使用 Angular 的面包屑功能.我将此 javascript 文件添加到我的服务文件夹中.

我在 header.html 文件中添加了一个 div 来调用 javascript.根据 Angular，div 应该是这样的:

<ul class="面包屑"><li ng-repeat="面包屑中的面包屑.getAll()"><span class="divider">/</span><ng-switch on="$last"><span ng-switch-when="true">{{breadcrumb.name}}</span><span ng-switch-default><a href="{{breadcrumb.path}}">{{breadcrumb.name}}</a></span></ng-switch>

正在创建 div，当我检查它时，我看到
<!-- ngRepeat:breadcrumbs.getAll() 中的面包屑 -->

但是没有面包屑.有什么想法吗?

解决方案

仅将 HTML 添加到标头模板文件是不够的.确保您还完成了以下操作:

1. 在主 HTML 模板(通常是 index.html)中包含 breadcrumbs.js:

   <script type="text/javascript" src="your-project-folder/services/breadcrumbs.js"></script>

2. 包括 services.breadcrumbs 作为主应用程序的模块依赖项:

   angular.module('myMainApp', ['services.breadcrumbs']);

3. 最后，确保您确实将 breadcrumbs 服务注入到您的控制器中，然后将其附加到 $scope:

   angular.module('myMainApp').controller('FooBarCtrl', function($scope, breadcrumbs) {$scope.breadcrumbs = 面包屑；//... 其他控制器逻辑 ...});

在angular-app项目中可以看到第2步和第3步的实现在 app.js 文件中(参考第 6、60 和 62 行).

I want to use Angular's breadcrumb capability. I added this javascript file to my services folder.

I added a div to my header.html file to call the javascript. According to Angular, the div should look like this:

<div>
  <ul class="breadcrumb">
    <li ng-repeat="breadcrumb in breadcrumbs.getAll()">
      <span class="divider">/</span>
      <ng-switch on="$last">
        <span ng-switch-when="true">{{breadcrumb.name}}</span>
        <span ng-switch-default><a href="{{breadcrumb.path}}">{{breadcrumb.name}}</a></span>
       </ng-switch>
    </li>
   </ul>
</div>

The div is being created, and when I inspect it I see
<!-- ngRepeat: breadcrumb in breadcrumbs.getAll() -->

But no breadcrumbs. Any ideas?

解决方案

It's not enough to just add the HTML to your header template file. Make sure you've also completed the following:

1. Include breadcrumbs.js in your main HTML template (usually index.html):

   <script type="text/javascript" src="your-project-folder/services/breadcrumbs.js"></script>
   

2. Include services.breadcrumbs as a module dependency for your main app:

   angular.module('myMainApp', ['services.breadcrumbs']);
   

3. Finally, make sure you actually inject the breadcrumbs service into your controller, and then attach it to $scope:

   angular.module('myMainApp').controller('FooBarCtrl', function($scope, breadcrumbs) {
       $scope.breadcrumbs = breadcrumbs;
   
       // ... other controller logic ...
   });
   

You can see the implementation of Steps 2 and 3 in the angular-app project in the app.js file (refer to lines 6, 60, and 62).
