methods 中获取的数据给data 里面中的items 属性赋值直接异常，没有填充数据
代码、：
<template><div class="videoresource"><div><b-cardtitle="资源列表"><b-car-text><b-form inline><label class="sr-only" for="fileno" >资源编号</label><b-form-inputid="fileno"class="mb-3 mr-sm-1 mb-sm-2"placeholder="请输入编号" v-model="filenumber"></b-form-input><b-button @click="onSearch" variant="primary" class="mb-3 mr-sm-1 mb-sm-2" >查询</b-button></b-form></b-car-text></b-card><b-table striped hover :items="items" :fields="fields" primary-key="ID"></b-table></div></div></template><script>export default {name:'videoresource',data(){return{filenumber:'',items:'',fields:['文件名称','文件路径','文件编号','创建时间']}},methods: {onSearch:function(){alert('小鸭子');debugger;this.$axios.get("哥哥哥哥哥哥").then(res=>{alert('黄鸭子');debugger;console.log(res);let a = JSON.parse(res.data)console.log(a.Result);debugger;if(res.status=="200" && a.Result=="0"){console.log(a.DateList);var ResListInfo=JSON.stringify(a.DateList);console.log(ResListInfo);this.items=ResListInfo;}else{alert('没有数据')}}).catch(err => {console.log(err)});}},created(){// this.onSearch();}}</script><style scoped>.videoresource{position: absolute;left: 200px;top:100px;width: 100%;}</style>
