html中使用Vue+element UI动态创建表单数据不显示问题
直接上代码：html代码如下
<!DOCTYPE html>
<html lang="en"><head><meta charset="UTF-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width, initial-scale=1.0"><script src="./js/commen.js"></script><!-- 引入样式 --><link rel="stylesheet" href="css/index.css"><link rel="stylesheet" href="css/elementui.css"><title>Document</title>

</body>
</html><!-- 引入组件库 -->
<script src="./js/vue.js"></script>
<script src="./js/elementui.js"></script>
<script src="./js/vue-resource.min.js"></script>
<script>new Vue({el: '#app',data: function () {return {form: {testDate: [] //每条记录},inputValue: '',}},created() {this.postMessage()// window.callJsFunction = this.callJsFunction},methods: {getMessage() {this.$http.get('http://localhost:3003/report').then(function (result) {console.log(result)})},postMessage() {this.$http.post('http://localhost:3003/report', {}).then(function (result) {this.inputValue = result.body.ReportTitleconst data = result.body.datathis.form.testDate = datathis.form.testDate.forEach((a) => {console.log(a.note + '嘿嘿嘿111')})})}}});</script>
<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
