vue监听路由变化时watch方法会执行多次的原因及解

const route = {
        name: 'BpageName',
        params: { orderId: this.tableData[index].id },
        meta: {
          title: 'B页面'
        }
      }
this.$router.push(route)

@Watch('$route.params.packageId')
routeParamsChanged(newParams: any, oldParams: any) :void { // 通过监听传参的变化来重新复制参数
    if (newParams) {
      this.getList(newParams)
    }
}

if (this.$route.fullPath === 'A页面路由路径') {
    // do something
}

@Watch('$route')
routeParamsChanged(newParams: any, oldParams: any) :void { // 通过监听传参的变化来重新复制参数
    if (newParams === '/Apage') {
      this.getList(newParams)
    }
}

private activatedFlag: boolean = false
activated () {
    this.activatedFlag = true;
}

deactivated () {
    this.activatedFlag = false;
}
@Watch('$route')
routeParamsChanged(newParams: any, oldParams: any) :void { // 通过监听传参的变化来重新复制参数
    if (newParams && this.activatedFlag) {
      this.getList(newParams)
    }
}

private activatedFlag: boolean = false
activated () {
    this.activatedFlag = true
    if (this.$route.params.orderId && this.activatedFlag) {
      this.getList(this.$route.params.orderId)
    }
}

deactivated () {
    this.activatedFlag = false;
}
