优化这段代码 // 剧场销售开始日期 salesStartChange() { this.timeProcessing(this.form.saleStartDate, this.form.saleEndDate); } // 剧场销售结束日期 salesEndChange(date: string) { this.timeProcessing(this.form.saleStartDate, this.form.saleEndDate); } // 剧场游玩开始日期 playStartChange() { this.timeProcessing(this.form.playStartDate, this.form.playEndDate); } //剧场游玩结束日期 playEndChange() { this.timeProcessing(this.form.playStartDate, this.form.playEndDate); } timeProcessing(startDate: any, endDate: any) { if (this.form.productType == 3 && this.selectUsers.length > 0) { if (new Date(startDate).getTime() === new Date(endDate).getTime()) { this.getSessionManageList( date.format(new Date(startDate), "YYYY-MM-DD") ); } } }

可以将四个函数合并成一个函数，然后在每次日期变化时调用该函数，同时去掉日期转换的重复计算。代码如下：

dateChange() {
  if (this.form.productType == 3 && this.selectUsers.length > 0) {
    const saleStartDate = new Date(this.form.saleStartDate).getTime();
    const saleEndDate = new Date(this.form.saleEndDate).getTime();
    const playStartDate = new Date(this.form.playStartDate).getTime();
    const playEndDate = new Date(this.form.playEndDate).getTime();
    if (saleStartDate === saleEndDate) {
      this.getSessionManageList(
        date.format(new Date(saleStartDate), "YYYY-MM-DD")
      );
    } else if (playStartDate === playEndDate) {
      this.getSessionManageList(
        date.format(new Date(playStartDate), "YYYY-MM-DD")
      );
    }
  }
}

这样可以避免重复计算，提高代码的可读性和可维护性。
