Angular JS - 如何在 ng-repeat 中添加额外的 DIV [英] Angular JS - How to add extra DIV in ng-repeat

问题描述

我有一个数组 a=[1,2,3,4,5,6].

在这个数组上使用 ng-repeat，我创建了 6 个 div.

请参阅此plunker

有没有办法在每一行之后再添加一个div.所以在 3 个 div 之后，我想添加一个额外的 div.

我查看了这个例子.但他们正在创建一个子div.是否可以在 ng-repeat

中创建同级 div

解决方案

让我们试试 ng-repeat-start &ng-重复结束.

<div class="square" ng-repeat-start="friend in a">{{$index}}
<div ng-if="$index % 3 == 2" ng-repeat-end>额外的div

请注意，从 angular 1.2.1 开始包含 ng-repeat-start 指令.

plnkr 演示

ng-repeat:重复一个"父元素的一系列元素

<!--====中继范围======--><Any ng-repeat="朋友中的朋友"></任何><!--====中继器范围结束======-->

ng-repeat-start &ng-repeat-end:使用ng-repeat-start和ng-repeat-end定义扩展中继范围的起点和终点

<!--====中继范围从这里开始======--><任何 ng-repeat="朋友中的朋友" ng-repeat-start>{{friend.name}}</Any><!-- ng-repeat 元素不再是重复范围的终点--><!--仍在中继器范围内--><h1>{{friend.name}}</h1><!--带有ng-repeat-end"指令的HTML标签定义范围的终点--><页脚ng-repeat-end></页脚><!--====中继器范围结束======-->

I have an array a=[1,2,3,4,5,6].

Using ng-repeat on this array, I am creating 6 divs.

Please refer to this plunker

Is there any way to add one more div after each row. So after 3 divs I want to add one extra div.

I looked into this example. but they are creating a child div. is it possible to create a sibling div in ng-repeat

解决方案

Let's try ng-repeat-start & ng-repeat-end.

<div class="example-animate-container">
  <div class="square" ng-repeat-start="friend in a">
   {{$index}}
  </div>
  <div ng-if="$index % 3 == 2" ng-repeat-end>
    extra div
  </div>
</div>

Please note that ng-repeat-start directive is included since angular 1.2.1.

plnkr demo

ng-repeat: repeat a series of elements of "one" parent element

<!--====repeater range=====-->
  <Any ng-repeat="friend in friends">
  </Any>
<!--====end of repeater range=====-->

ng-repeat-start & ng-repeat-end: using ng-repeat-start and ng-repeat-end to define the start point and end point of extended repeater range

<!--====repeater range start from here=====-->
<Any ng-repeat="friend in friends" ng-repeat-start> 
  {{friend.name}}
</Any><!-- ng-repeat element is not the end point of repeating range anymore-->

<!--Still in the repeater range-->
<h1>{{friend.name}}</h1>

<!--HTML tag with "ng-repeat-end" directive define the end point of range -->
<footer ng-repeat-end>
</footer>
<!--====end of repeater range=====-->
