单选框组存值问题

Question

如图所示：

怎样将单选选择生成的对象变为[{},{},{}]的格式？
代码如下：

<div v-if="item.type == 1">
                    <p class="question_main_title">
                      {{ index + 1 }}.{{ item.describe }}
                    </p>
                    <div
                      v-for="(items, indexs) in item.answer.split(',')"
                      :key="indexs"
                    >
                      <el-radio-group
                        v-model="answer1[index]"
                        class="question_main_radio"
                        @change="changeHandler(index,item.id,item.questionnaireId,item.type)"
                      >
                        <el-radio :label="items">{{ items }}</el-radio>
                      </el-radio-group>
                    </div>
 </div>

// 单选题答案
    changeHandler(index,id,questionnaireId,type) {
      this.id=id;
      this.questionnaireId=questionnaireId;
      this.type=type;
      
      //单选题选择对象
      var obj1={};
      obj1.trainId=this.train_id;
      obj1.questionId=this.id;
      obj1.questionnaireId=this.questionnaireId;
      obj1.describe=this.answer1[index];
      console.log(obj1);

},

求指点，我一直把它们存不到一起，谢谢！！！

先初始化答题卡，然后根据v-model 自动绑定索引的答案。

[{'questionnaireId':'123456','questionId':'1','questionType':1,'questionDescribe':'性别','questionOptions':['男','女'],'questionAnswer':'女','describe':'女'},{'questionnaireId':'123456','questionId':'2','questionType':1,'questionDescribe':'年龄','questionOptions':['27','17'],'questionAnswer':'27','describe':'27'},{'questionnaireId':'123456','questionId':'3','questionType':2,'questionDescribe':'爱好','questionOptions':['购物','看电视剧'],'questionAnswer':['看电视剧','购物'],'describe':'看电视剧,购物'}]

demo

将每个多选框的model分别绑定，然后用map统一输出

  <div v-for='(item,index) in dataList' :key='index'>
      <h4>{{item.name}}</h4>
      <el-checkbox-group v-model="item.data" @change='print'>
        <el-checkbox :label="itemChild" v-for='(itemChild,dx) in item.list' :key='dx'></el-checkbox>
      </el-checkbox-group>
    </div>

  data() {
    return {
      dataList: [
        {
          name: "性别",
          list: ["男", "女"],
          data:[]
        },
        {
          name: "对我的答案是否满意",
          list: ["满意", "不满意"],
          data:[]
        }
      ]
    };
  },
  methods:{
    print(){
      ////console.log(this.dataList)
      console.log(this.dataList.map(e=>e.data))
    }
  }
