通过切片与指数增量 [英] Slice by Index with increment

问题描述

我有这样的事情：

<div ng-repeat="atma in abc">
   <li ng-repeat="atma in abc.slice(0,3)"><span>{{$index+1}} - {{atma.weapon}} </span></li>
</div>

我想这些切片的结果，每个div重复，每次使用从指数的3个项目。

I wanted to slice these results at, each div repeat, each time being used the 3 items from index.

因此​​，我将开始与展示范围从1到3武器的第一个div。
第二个将具有4至6个元素。
等等。

So I would start with the first div showing the weapons ranging from 1 to 3. The second one would have elements from 4 to 6. And so on.

我可以用$指数或类似的东西在我的片？

Can I use $index or something like that on my slice?

诗：这个问题来自试穿<一个我最好的href=\"http://stackoverflow.com/questions/27533682/repeating-a-determined-ammount-of-times-inside-another-ng-repeat\">this问题在这里。
我仍然有一些麻烦，但我做了基于什么我可以做切片另一个问题。

Ps.: This question came from trying my best on this question here. I'm still having some trouble, but I made another question based on what I could do with slice.

<div ng-repeat="atma in data">
   <ul ng-if="$index % 3 == 0">
       <li><span>{{data[$index]}} </span>
       </li>
       <li ng-if="$index+ 1 < data.length"><span>{{data[$index+1]}} </span>
       </li>
       <li ng-if="$index+ 2 < data.length"><span>{{data[$index+2]}} </span>
       </li>
   </ul>
</div>

2日：

<div ng-repeat="atma in data">
   <ul ng-if="$index % 3 == 0" ng-init="tmp = data.slice($index, $index + 3)">
       <li ng-repeat="atma1 in tmp"><span>{{atma1}}</span>
       </li>
   </ul>
</div>
