嵌套元素NG重复数目不详

问题描述

我想知道如果有一个简单的解决此类问题。

I'm wondering if there is a simple solution to this type of problem.

我有一个对象评论，这反过来又会包含注释，这些注释也可以包含注释...这可以去一个未知的周期数。

I have an object comment, which can in turn contain comments, and those comments can also contain comments ...and this can go on for a unknown number of cycles.

下面是数据结构的示例：

Here is an example of the data structure:

var comment = {
   text : "",
   comments: [
      { text: "", comments : []},
      { text: "", comments: [
         { text: "", comments : []},
         { text: "", comments : []}
         { text: "", comments : []}
      ]}
   ]
}

比方说2级的意见，我会写：

Lets say for 2 levels of comments I would write:

<div ng-repeat="comment in comments">
   {{comment.text}}
   <div ng-repeat="comment in comments">
      {{comment.text}}
   </div>
</div>

我将如何implent我的div的嵌套评论N的水平？

How would I implent my divs for "n" level of nested comments ?

推荐答案

最简单的方法是创建一个通用的部分，所以你可以递归调用，并使用使其 NG-包括。

The easiest way is to create a generic partial so you can recursively call and render it using ng-include.

<div ng-include="'partialComment.html'" ng-model="comments"></div>

下面是部分：

<ul>
    <li ng-repeat="c in comments">
      {{c.text}}
      <div ng-switch on="c.comments.length > 0">
        <div ng-switch-when="true">
          <div ng-init="comments = c.comments;" ng-include="'partialComment.html'"></div>  
        </div>
      </div>
    </li>
</ul>

数据模型应该是一个List VAR评论= [{...}] 。
