优化这段代码 if (this.form.salesTime == "sales") { this.dateChange(this.form.saleStartDate, this.form.saleEndDate); } else { this.dateChange(this.form.playStartDate, this.form.playEndDate); } } /** * 开始时间和结束时间才能查询同一天的数据 */ dateChange(saleStartDate?:string,saleEndDate?:string,playStartDate?:string,playEndDate?:string) { 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") ); } } }

可以将if-else语句替换为三元表达式，简化代码逻辑，如下：

const startDate = this.form.salesTime == "sales" ? this.form.saleStartDate : this.form.playStartDate;
const endDate = this.form.salesTime == "sales" ? this.form.saleEndDate : this.form.playEndDate;
this.dateChange(startDate, endDate);

同时，可以将参数移除，直接在函数内部获取开始时间和结束时间，如下：

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

最后，可以将函数名改为更具体的名称，比如`querySameDayData`，以便更好地表达函数的作用。
