使用具有多个重复ng的单选按钮组的ng-model

Question

参见JsBin

我有一个由ng-repeat生成的checkpoints的动态列表，每个项目有六个单选按钮。我需要将每个集合绑定到一个$scope对象。

下面，你可以看到我已经将名称设置为selectedOption1, selectedOption2等…这允许每个ng-repeated列表独立于下一个。现在，我需要将这些selectedOptionX组的选定选项绑定到$scope对象，同时仍然保持对象中的checkpoint.Name。

<table>
  <tbody>
    <tr ng-repeat="checkpoint in checkpoints">
      <td>{{checkpoint.Name}}</td>
      <td><input type="radio" name="selectedOption{{$index}}" value="pass" /></td>
      <td><input type="radio" name="selectedOption{{$index}}" value="fail" /></td>
      <td><input type="radio" name="selectedOption{{$index}}" value="remediated" /></td>
      <td><input type="radio" name="selectedOption{{$index}}" value="nc" ng-checked="true" /></td>
      <td><input type="radio" name="selectedOption{{$index}}" value="na" /></td>
      <td></td>
      <td></td>
    </tr>
  </tbody>
</table>

输出对象可能像这样:

[
    {
        Name: "the first checkpoint",
        Value: "remediated"
    },
    {
        Name: "the second checkpoint",
        Value: "fail"
    },
    {
        Name: "the third checkpoint",
        Value: "pass"
    },
];

What I've try…

<td><input type="radio" name="selectedOption{{$index}}" value="pass" ng-model="selectedOption{{$index}}"/></td>
//and
<td><input type="radio" name="selectedOption{{$index}}" value="pass" ng-model="selectedOption[$index]"/></td>
//and
<td><input type="radio" name="selectedOption{{$index}}" value="pass" ng-model="selectedOption.$index"/></td>
//and
<td><input type="radio" name="selectedOption{{$index}}" value="pass" ng-model="checkpoint.Name"/></td>

我也试过其他方法，但都不如。

试试这个，它将在检查点对象中设置选定的值

http://jsbin.com/barufuhi/3/edit

<div ng-controller="CheckpointsController">
<table>
  <tbody>
    <tr ng-repeat="checkpoint in checkpoints">
      <td>{{checkpoint.Name}}</td>
      <td><input type="radio" ng-model="checkpoint.value" value="one"></td>
      <td><input type="radio" ng-model="checkpoint.value" value="two"></td>
      <td><input type="radio" ng-model="checkpoint.value" value="three"></td>
      <td><input type="radio" ng-model="checkpoint.value" value="four"></td>
      <td><input type="radio" ng-model="checkpoint.value" value="five"></td>
      <td><input type="radio" ng-model="checkpoint.value" value="six"></td>
      <td></td>
      <td></td>
    </tr>
  </tbody>
</table>
</div>
