1、效果图：

2、需求&实现：

输入条件 下面匹配查询到的数据有多少个 需要调用后端接口展示，后端查询到之后返回条数 前端展示

3、具体代码实现：

html： 图片需要自己根据实际情况增加  // 查询 重置 筛选  本文章只写查询 重置和更多筛选逻辑自行添加

<divclass="topSearch"ref="topSearch"><div class="top-search-group"><el-popoverplacement="bottom"width="500px"trigger="manual"v-model="visible"ref="popover"popper-class="peopleSelectPopper"><divclass="linkageDiv"v-for="(item,index) in queryList":key="index"><div @click="linkageDivClick(item)">{{item.queryType}}：<span :class="{spanData:Number(item.number)>0,spanNoData:Number(item.number)==0}">{{item.number}}</span>条</div></div><divstyle="display:flex;"slot="reference"><el-inputwidth="500px"placeholder="请输入查询条件1/查询条件2/查询条件3/查询条件4/查询条件5/查询条件6"size="medium"@input="debouncedInput"@click.native="openPopover"v-model="queryDataLabel"ref="input"></el-input><divclass="searchBtn"style="font-size:20px;width: 46px;height: 40px;padding:0px"@click="getGridDataEvt('search', true)"><imgsrc="../../assets/images/search.png"alt=""></div></div></el-popover><divclass="iconBtn"@click="getGridDataEvt('reset')"><el-tooltipclass="item"effect="dark"content="重置"placement="top"><imgsrc="../../assets/images/chongzhi.png"alt=""></el-tooltip></div><el-tooltipclass="item"effect="dark"content="筛选"placement="top"><divclass="iconBtnShaixuan":class="{active:!searchFilterFlag}"@click="searchFilterFlagClick()"><imgv-if="!searchFilterFlag"src="../../assets/images/shaixuanClick.png"alt=""></div></el-tooltip></div></div>

js代码逻辑

//接口需要自己引入
import { selectNum } from "@/api/xxxx"
export default {data() {return {searchFilterFlag: false,visible: false,//初始的一些查询条件searchData: {queryData: "",orderByKeyWord: "",ascOrDesc: "",orderByRule: "",},queryDataLabel: "",queryList: [{queryType: `查询条件1`,queryParam: "workNo",number: 0,},{queryType: `查询条件2`,queryParam: "personName",number: 0,},{queryType: `查询条件3`,queryParam: "pmpName",number: 0,},{queryType: `查询条件4`,queryParam: "phone",number: 0,},{queryType: `查询条件5`,queryParam: "graduationInstitution",number: 0,},{queryType: `查询条件6`,queryParam: "insurancesPlace",number: 0,},],timer: null,queryParam: "",}},mounted() {//增加一个全局监听 方便点击其他位置可以关闭el-popoverdocument.addEventListener('click', this.handleDocumentClick);},methods: {//点击查询条件的每一条数据linkageDivClick(item) {this.visible = false;// 我们需要把这个值给后端传过去this.queryParam = item.queryParam;// 原本的查询条件中 searchData 所有值需要置空for (let key in this.searchData) {this.searchData[key] = ""}this.searchData[item.queryParam] = this.queryDataLabel;//去调用查询接口 this.getGridDataEvt('search', false)},openPopover() {this.visible = true;this.debouncedInput(this.queryDataLabel)},// 下拉框查询接口debouncedInputApi(val) {selectNum({ queryData: val }).then(res => {if (res.code == 200) {let data = res.datathis.queryList.forEach(item => {for (let key in data) {if (item.queryParam == key) {item.number = data[key]}}})} else {this.$message.error('数据获取失败');}}).catch(err => {this.$message.error(err.msg);})},// 输入框触发debouncedInput(val) {clearTimeout(this.timer);//   防抖this.timer = setTimeout(() => {this.debouncedInputApi(val)}, 500);},},beforeDestroy() {//清除定时clearTimeout(this.timer);// 移除监听document.removeEventListener('click', this.handleDocumentClick);},}

样式style  具体效果还是需要自己微调
