angular.js - angular中，ng-reprat双层循环下，radio和checkbox怎么取值？

问题描述

问 题

ng-repeat中嵌套一个ng-repeat radio和checkbox怎么取值? 代码如下：

<ul class="options_box" >
    <li ng-repeat="item in ques.ques_items">
        <div ng-repeat="nums in item.ques_item_options" ng-if="item.ques_item_type==1">
            <input type="radio" class="magic-radio " ng-model="nums.option_id" >
            <label for="{{nums.option_id}}">22222</label>
        </div>
        <div ng-repeat="nums in item.ques_item_options" ng-if="item.ques_item_type==2">
            <input type="checkbox"  " class="magic-radio " ng-model="nums.option_id" >
            <label for="{{nums.option_id}}">22222</label>
        </div>
    </li>
 </ul>

怎么在双层ng-repeat情况取到input[radio]和input[checkbox]? ng-model应该怎么设置？

解决方案

    <ul class="options_box" >
        <li ng-repeat="item in ques.ques_items">
            <div ng-repeat="nums in item.ques_item_options" ng-if="item.ques_item_type==1">
                <input type="radio" class="magic-radio " id="{{item.ques_item_id}}{{nums.option_id}}" name="{{item.ques_item_id}}" value="{{nums.option_id}}" ng-model="result[item.ques_item_id]">
                <label for="{{item.ques_item_id}}{{nums.option_id}}" ng-bind="nums.option_label"></label>
            </div>
            <div ng-repeat="nums in item.ques_item_options" ng-if="item.ques_item_type==2">
                <input type="checkbox" class="magic-radio" id="{{item.ques_item_id}}{{nums.option_id}}" ng-model="result[item.ques_item_id][nums.option_id]">
                <label for="{{item.ques_item_id}}{{nums.option_id}}" ng-bind="nums.option_label"></label>
            </div>
        </li>
     </ul>

        $scope.result = {};

        $scope.ques = {
