1.父组件写法

初始化：

//引入子组件  
<odialog ref="odialogRef" @onSure="onSurea"></odialog>
//子传父private onSurea() {// 初始化信息/重新叫号来的数据this.initTabelData()setTimeout(() => {// 播放声音的数据this.searchCallInfo()}, 2000)}activated() {// 初始化信息/重新叫号来的数据this.initTabelData()// 播放声音的数据this.searchCallInfo()}// 一开始进入的时候激活一下，表格的数据private async initTabelData() {let res = await getCallInfo()this.tableData = res}// 一开始进入的时候激活一下private async searchCallInfo() {try {//需要播报的文字数据let res = await getALLCallText()// 如果有数据if (res.data !== '') {clearTimeout(this.timer)// 打开弹窗播放数据;(this.$refs.odialogRef as any).openDialog(res)} else {// 如果没有数据，5秒后获取一次表格所有数据this.timer = setTimeout(() => {this.initTabelData()console.log('(((((((((((((((((((((((((((((获取数据)))))))))))))))))))))))))))))')// 播放声音的数据this.searchCallInfo()}, 10000)}} catch (error) {this.$message({message: error,type: 'error'})}}

 2.子组件写法

template写法：

<template><el-dialog :show-close="false" title="叫号显示" :visible.sync="customerDialogVisible" top="200px" width="40%" center :close-on-click-modal="false"destroy-on-close append-to-body><div class="details"><div style="font-size:50px" @click="playVoice" id="playVoiceButton">{{carName}}</div><div style="font-size:50px" @click="playVoice" id="playVoiceButton">{{detail}}</div><!-- <div v-else>没有叫号数据！</div> --><!-- <div style="font-size:50px" v-if="this.text==''">没有叫号数据！</div> --></div></el-dialog></template>

方法：

  // 车牌号private carName: string = ''// 鹤位地点private detail: string = ''//   dialog打开后携带需要播报的数据private async openDialog(data) {this.callTextInfo = data// 截取文字let str = data.split(' ')this.detail = str[str.length - 1]this.carName = str[str.length - 3]this.customerDialogVisible = trueawait this.$nextTick()// 播放声音await this.playVoice()}//播放声音private async playVoice() {// 四秒后播放一次声音this.handleSpeak(this.callTextInfo)await setTimeout(() => {this.handleSpeak(this.callTextInfo)}, 4000)// 播放声音十秒后关闭await setTimeout(() => {this.customerDialogVisible = falsethis.onSure(null)}, 10000)}//刷新@Emit('onSure')private onSure(row: any) {}

3.全部写法：

//父组件：
<template><div class="fullScreenBox"><!-- <el-button type="primary" v-if="fullScreenSwitch" @click="fullScreenFn">全 屏</el-button><el-button type="primary" v-else @click="goBack">退 出</el-button> --><xTable ref="xtable" :tableData="tableData" :tablePage="tablePage" :showSearchBox="false" :isShowPage="false" :showOperationBtn="true" :tableConfigure="tableConfigure" :showClearSearchInfoBtn="false"><template #optionBtns><div class="operationBtnBox"><el-row><el-button type="primary" v-if="fullScreenSwitch" @click="fullScreenFn"><div><p style="color:#fff">全 屏</p></div></el-button><el-button type="primary" v-else @click="goBack"><div><p style="color:#fff">退 出</p></div></el-button></el-row></div></template><template v-slot:columns><vxe-column type="seq" width="50px" align="center"></vxe-column><vxe-column field="carNumber" title="车牌号" width="6.6%" align="center"></vxe-column><vxe-column field="driverName" title="驾驶员姓名" width="6.6%" align="center"></vxe-column><vxe-column field="pickUpNo" title="提货单号" width="6.6%" align="center"></vxe-column><vxe-column field="createTime" title="入场时间" width="6.6%" align="center"></vxe-column><vxe-column field="equDao" title="岛" width="6.6%" align="center"></vxe-column><vxe-column field="equName" title="鹤位名称" width="6.6%" align="center"></vxe-column><vxe-column field="state" title="状态" width="6.6%" align="center"></vxe-column></template></xTable><odialog ref="odialogRef" @onSure="onSurea"></odialog></div>
