vue2+TS获取到数据后自动叫号写法

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 = true
    await 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 = false
      this.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="createTime" title="入场时间" 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>
