this.inputValue = result.body.ReportTitle
const data = result.body.data

<style>
.zh {
border: 0px;
outline: none;
cursor: pointer
}
</style>我这里后台数据是模拟的，返回的数据格式：
理想的是页面创建时就向后台获取数据，然后将数据渲染在页面上，可是失败了，但是控制台也没有报错，只有单独绑定数据的ReportTitle渲染成功。
最后问了大佬才发现，因为我用的是Vue2，必须要用this
Vue3才可以不用this
将代码改为：
<el-row class="b3" v-for="(item,index) in this.form.testDate" :key="index">最后就成功显示啦，就是格式不太对，但是可以显示成功了
