比如
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
long kssj = format.parse(kssj).getTime();
如：string kssj='2005-1-1',string jssj='2005-12-31'
否则时间默认为一天开始的时刻00:00:002、只给同一月只是为了测试方便，否则输出太长了不便于检查
你可以传入任何合法的日期时间
t = new Date(Date.parse(s.replace(/-/g, '/')));
document.write(t.getTime());
输出
1133420313000
只能精确到毫秒我只能负责解答我的回复！
在我的代码中是按天加的
不是加一个月，而是调整显示值
getMonth()方法返回的月是从0算起的所以要加一

kssjArray,jssjArray是string[]吗？a，b又是什么类型？
----------------------------------
谢谢了，不好意思，因为不懂，问了愚蠢的问题，那i是什么类型，如果是java.util.Date，怎么可以减86400000？如果是int，怎么可以把new java.util.Date付给它
------------------------------------------
这个是Date，但是不是你说的java.util.Date,注意java和javascript一点关系都没有。
86400000是1000*60*60*24得来的一天的毫秒数，当然可以减---------------------------------------------------------
还有kssjArray=kssj.split("-");
var a=new Date(kssjArray[0],kssjArray[1]-parseInt(1),kssjArray[2]);
jssjArray=jssj.split("-");
var b=new Date(jssjArray[0],jssjArray[1]-parseInt(1),jssjArray[2]);
-------------------------------------------------------------------
这里的也不是string[]类型
是一个数组
在JS中只有var 这个定义，就是说不管什么类型都是这个定义。
其实我想实现的功能就是在页面上选好两个日期时间，传到后台java里，然后把这两个日期之间的所有日期和对应星期几存到数据库的表里
传到后台，难道把中间所有的日期都以对象的形式传到后台吗？应该只传两个边界点，到后台用JAVA在分，JAVA中分也不难的
用GregorianCalendar这个类
后者直接用架构中sql中的循环
