Angularjs 模型中未反射的离子无线电组

所以我从一个api加载了一堆问题，每个问题都有自己的答案

Im无法填充ng model for radio box以记录所选答案

html

{{问题.文本}
{{option.text}

来自控制器的相关代码

vm.answers=[]；
api.need\u assessment\u questions.query(
//论成功
功能成功（响应）{
vm.questions=回答；
//填充答案
对于（var i=0；i

我面临的问题是答案数组总是重写第一个答案文本

fiddle:

您需要在顶部初始化问题索引，并在您的模型中使用它，因为还有另一个

ng repeat

会覆盖以前的

$index

试试这个

<div class="list">
    <div class="item item-text-wrap" 
            ng-repeat="question in vm.questions track by $index" 
            ng-init="qIndex = $index">
        <h2>{{question.text}}</h2>
        <ion-list if="question.type='mcq'">
            <ion-radio ng-model="vm.answers[qIndex].answer_text" ng-value="option.text" ng-repeat="option in question.options" name="{{vm.answers[qIndex].answer_text}}">{{option.text}}</ion-radio>
        </ion-list>
        <input type="text" ng-if="question.type=='simple'" ng-model="vm.answers[$index].answer_text" placeholder="{{question.text}}" />
    </div>
</div>

{{问题.文本}
{{option.text}

正在工作

您能提供一把小提琴吗？@Gaurav yes here:，也在回答中更新您能给我一个包含无线电输入的问题数据吗？

vm.answers = [];

api.need_assesment_questions.query(
    //on success
    function success(response) {
        vm.questions = response;

        //populate answers 
        for (var i = 0; i < vm.questions.length; i++) {

            vm.answers.push({ question_text: vm.questions[i].text, answer_text: '' });

        }
    },
    //on error
    function error(response) {
        alert(response.message);
    }
);

<div class="list">
    <div class="item item-text-wrap" 
            ng-repeat="question in vm.questions track by $index" 
            ng-init="qIndex = $index">
        <h2>{{question.text}}</h2>
        <ion-list if="question.type='mcq'">
            <ion-radio ng-model="vm.answers[qIndex].answer_text" ng-value="option.text" ng-repeat="option in question.options" name="{{vm.answers[qIndex].answer_text}}">{{option.text}}</ion-radio>
        </ion-list>
        <input type="text" ng-if="question.type=='simple'" ng-model="vm.answers[$index].answer_text" placeholder="{{question.text}}" />
    </div>
</div>
