jquery存款利息计算！！！
问题描述：
如图片上的一样 俩个问题
一、如果存入日期是5 .31 号的话 那就 三个月 到期日是 8.31 六个月是11.30 也就是说默认最后一天到期日 如果是 5.21 那三个月就是 8月21 六个月就是 11月 21 以此类推 还要考虑进去 2月份的情况 我想问的是 在我源代码的情况下 添加什么能实现
二、 我写额下面到期日 默认是当天日期 加上多少天=到期日 但是我想改变了 存入日期 下面的到期日 也改变 比如说 存入是 5.24 一天到期日就是 5.25 这样
声明： 最好在我原先上的代码 去改 如果另写我还的重新去琢磨什么意思 时间紧 谢谢
下面我截取代码一下部分 能运行的
答
改3个月和6个月这个地方，时间计算部分
d = new Date(utc);
var m1 = d.getMonth() + 1 + 3; //目标月份
if (m1 > 12) m1 = m1 % 12;
d.setMonth(d.getMonth() + 3);
if (d.getMonth() + 1 != m1){//出现进位操作，需要循环-1直到和目标月份一致
do { d.setDate(d.getDate() - 1); } while (d.getMonth() + 1 != m1);
}
d = new Date(utc);
var m1 = d.getMonth() + 1 + 6;//目标月份
if (m1 > 11) m1 = m1 % 12;
d.setMonth(d.getMonth() + 6);
if (d.getMonth() + 1 != m1) {
do { d.setDate(d.getDate() - 1); } while (d.getMonth()+1 != m1)
}

那不是存入日期也加入就行了，修改存入日期自动调用你那个计算公式

多少个月，多少年用setMonth和setYear，而不是setDate
