ng-repeat 中的 md-radio-group

Question

我正在整理一份调查问卷。每个问题都插入一个 ng-repeat，每个问题都有多项选择项。我使用 angular material 的 md-radio-group 将这些多项选择项作为单选按钮插入。 在问题 1 中选择这三个单选按钮之一会反映以下所有问题。任何帮助表示赞赏。

更新：我创建了一个重复问题的 CodePen。发现于：

<div class="main" ng-app="MyApp">

<div ng-controller="AppCtrl as asaq">

<h1>{{ asaq.title }}</h1>

Answer 1

您正在使用相同的scope 变量来存储所有答案。每个答案都需要单独的变量。所以看看这支笔。我刚刚添加了一个字段来将答案存储在questions 对象中。
