The 日期构造器 [

The Date constructor[^] does not use dd/mm/yyyy but mm/dd/yyyy.

Use

var arrStartDate = startDate.value.split("/");
var date1 = new Date(arrStartDate[2], arrStartDate[1], arrStartDate[0]);
var arrEndDate = endDate.value.split("/");
var date2 = new Date(arrEndDate[2], arrEndDate[1], arrEndDate[0]);

从字符串中获取正确的日期对象.
