Vue Autocomplete 自动完成功能简单示例

<el-autocomplete v-model="state4" :fetch-suggestions="querySearchAsync" placeholder="请输入内容" @select="((item)=>{handleSelect(item, index)})"></el-autocomplete>

methods: {    querySearchAsync(queryString, callback) {      var list = [{}];      //调用的后台接口      //let url = 后台接口地址 + queryString;      //从后台获取到对象数组      this.$http({        url: this.$http.adornUrl('yjtgateway/goods'),        method: 'get',        params: this.$http.adornParams({keyword:queryString})      }).then(({data}) => {        for(let i of data.content){          i.value = i.goodsCode; //将想要展示的数据作为value        }        list = data.content;        callback(list);      }).catch((error) => {        console.log(error)      })    },    handleSelect(item,index) {     this.dataForm.items[index] = item    }}
