1.问题分析：

  在vue之前，我们想要获取某一组（设置相同的name属性）radio的选中状态是通过name属性获取，判断input的checked是true还是false，但是当列表中有多组（动态获取）就显得很乏力；vue出现后我们可以通过v-model很巧妙的完成。

2.vue中分析（完成代码请看后面）
```
  <input :name="item.COLUMN_CODE" :type="item.COLUMN_TYPE" v-model="item1.ISSELECT" value="true" :checked="item1.ISSELECT" :disabled="isAnswer" class="tui-checkbox">
```
我们将name绑定COLUMN_CODE设置为同一组radio或checkbox；v-model绑定返回的值ISSELECT（true/false），value=‘true’表示当ISSELECT的值为true是该radio或checkbox就自动选中，同理，当我们选中某一项时对应的ISSELECT自动切换成true。
vue官网描述的是无需设置name，但是我在项目中测试过是通不过的，因为还是无法识别是同一组还是不同组，所以建议读者加上。
3.完成代码（该例子中input是自定义的样式）

<div class="select-item" v-if="voteType == 'A' || voteType == 'B'" :key="index" v-for="(item, index) in detailList">
    <div class="family select-item-title" :attr="item.COLUMN_CODE" v-if="item.COLUMN_TYPE == 'radio'" v-html="item.COLUMN_NAME + '（单选）'"></div>
     <div class="family select-item-title" :attr="item.COLUMN_CODE" v-else-if="item.COLUMN_TYPE == 'checkbox'" v-html="item.COLUMN_NAME + '（多选）'"></div>
     <div class="family select-item-title" :attr="item.COLUMN_CODE" v-else v-html="item.COLUMN_NAME"></div>
     <div class="option-con" v-if="item.COLUMN_TYPE != 'text'" :key="index1" v-for="(item1, index1) in item.OPTION_LIST">
       <div class="option-con-row" v-if="item1.OPTION_TYPE != 'text'">
         <input :name="item.COLUMN_CODE" :type="item.COLUMN_TYPE" v-model="item1.ISSELECT" value="true" :checked="item1.ISSELECT" :disabled="isAnswer" class="tui-checkbox">
         <div class="family option-desc">{{item1.OPTION_NAME}}</div>
       </div>
       <div class="text-area-con" v-else>
         <div class="option-con-row">
           <input :name="item.COLUMN_CODE" :type="item.COLUMN_TYPE" v-model="item1.ISSELECT" value="true" :checked="item1.ISSELECT" :disabled="isAnswer" class="tui-checkbox">
           <div class="family option-desc">{{item1.OPTION_NAME}}</div>
         </div>
         <textarea class="text-area" rows="3" v-model="item1.OPTION_CONTENT" :readonly="isAnswer"></textarea>
       </div>
       <img class="option-con-img" v-if="item1.EMC_URL" :src="item1.EMC_URL">
     </div>
     <div class="option-con" v-if="item.COLUMN_TYPE == 'text'">
       <div class="text-area-con">
         <textarea class="text-area" rows="3" v-model="item.COLUMN_CONTENT" :readonly="isAnswer"></textarea>
       </div>
