angularjs:ng-repeat-start 和 ng-repeat-end 带有内部 ng-repeat

问题描述

我有一个简单的 ng-repeat-start 和 end 用例，并且工作正常，当我想添加内部 ng-repeat 时出现问题.这是我的代码

Hi I have a simple use case for ng-repeat-start and end and is working just fine, the problem appears when I want to add an inner ng-repeat.Here is the my code

<tr ng-repeat-start="obj in rows" >
  <td ng-repeat="e in obj.row">{{e}}</td>
</tr>
<tr ng-repeat-end>
  <td colspan="4">{{obj.description}}</td>
<tr>

td 元素中的内部 ng-repeat 不起作用，我在检查 html 源代码时看到了 ngRepeat 注释，但未创建 td 元素.

The inner ng-repeat into td element is not working, I'm seeing the ngRepeat comment when I inspect the html source code, but the td elements are not being created.

<!-- ngRepeat: e in obj.row -->

我丑陋的解决方法(假设我知道该向量的大小)是:

My ugly workaround (given that I know the size of that vector) is:

<tr ng-repeat-start="obj in rows" >
  <td>{{obj.row[0]}}</td>
  <td>{{obj.row[1]}}</td>
  <td>{{obj.row[2]}}</td>
  <td>{{obj.row[3]}}</td>
</tr>
<tr ng-repeat-end>
  <td colspan="4">{{obj.description}}</td>
<tr>

推荐答案

我不确定你是否在使用 angular 1.1.6，因为 ng-repeat-start 和 ng-repeat-end 在 1.1.5 或 1.0.7 中尚不可用.

I am not sure whether you are using angular 1.1.6 or not since ng-repeat-start and ng-repeat-end are not available in 1.1.5 or 1.0.7 yet.

但是，您实际上不必使用新指令来实现这一点.您现在可以像这样简单地实现它:

However, you don't actually have to use the new directives to achieve that. You can simply implement it like this for right now:

<table>
    <tbody ng-repeat="obj in rows">
        <tr ng-repeat="e in obj.row">
            <td>{{e}}</td>
        </tr>
        <tr>
            <td colspan="4">{{obj.description}}</td>
        <tr>
    </tbody>
</table>

AngularJS 1.1.6 正式发布时，可以使用ng-repeat-start和ng-repeat-end重新实现.

You may use ng-repeat-start and ng-repeat-end to reimplement it when AngularJS 1.1.6 version is officially released.
