Angular2-递归HTML而不制作新组件? [英] Angular2 - recursive html without making a new component?

问题描述

在角度1中，我可以执行以下操作:

In angular 1 I was able to do something like:

<script type="text/ng-template" id="commentView.html">
    <div>
        <div style="float: left; position: absolute;" ng-style="comment.displayPercent">
    </div>
</script>

<script type="text/ng-template" id="commentReplies.html">
    <div>
        <div class="commentChildBoxStyle" ng-hide="comment.hideComment">
            <div style="min-width: 250px;">

                <div ng-repeat="comment in comment.replies" ng-include="'commentReplies.html'"></div>
            </div>

        </div>
    </div>
</script>

我意识到我可以在Angular2中递归地调用组件及其模板，但是有没有办法仅递归地构建HTML?这种逻辑似乎更适合于父组件而不是一系列子组件.

I realize I can recursively call a component along with it's template in Angular2, but is there a way to recursively build HTML only? The logic seems like it would fit better with the parent component rather than with a series of child components.

推荐答案

在Angular中肯定只有html解决方案:

There certainly is a html only solution in Angular:

<h1>Angular 2 Recursive List</h1>
<ul>
  <ng-template #recursiveList let-list>
    <li *ngFor="let item of list">
      {{item.title}}
      <ul *ngIf="item.children.length > 0">
        <ng-container *ngTemplateOutlet="recursiveList; context:{ $implicit: item.children }"></ng-container>
      </ul>
    </li>
  </ng-template>
  <ng-container *ngTemplateOutlet="recursiveList; context:{ $implicit: list }"></ng-container>
</ul>

这是要点.
