问题描述

jQuery计算日期时间差和同步

如图片一样 计算俩个日期之间的时间差
并且更改开始时间或截止时间是下方的阴历开始跟截止同样改变，改变成同一天

大神帮帮小弟 最好带注释 感谢了

 <div class="maincontent">
                        <h2>在线日期计算</h2>

                            <script>//显示当前日期时间
                                setInterval("jnkc.innerHTML=new Date().toLocaleString()+'星期'+'日一二三四五六'.charAt(new Date().getDay());",1000);
                            </script>

解决方案

var date1 = new Date(2012, 4, 7, 11, 27); //开始时间
var date2 = new Date(2012, 4, 7, 12, 28); //结束时间
var date3 = date2.getTime() - date1.getTime(); //时间差的毫秒数
//计算相差的年数
var years = Math.floor(date3 / (12 * 30 * 24 * 3600 * 1000));
//计算相差的月数
var leave = date3 % (12 * 30 * 24 * 3600 * 1000);
var months = Math.floor(leave / (30 * 24 * 3600 * 1000));
//计算出相差天数
var leave0 = leave % (30 * 24 * 3600 * 1000);
var days = Math.floor(leave0 / (24 * 3600 * 1000));
//计算出小时数
var leave1 = leave0 % (24 * 3600 * 1000); //计算天数后剩余的毫秒数
var hours = Math.floor(leave1 / (3600 * 1000));
//计算相差分钟数
var leave2 = leave1 % (3600 * 1000); //计算小时数后剩余的毫秒数
var minutes = Math.floor(leave2 / (60 * 1000));
//计算相差秒数
var leave3 = leave2 % (60 * 1000); //计算分钟数后剩余的毫秒数
var seconds = Math.round(leave3 / 1000);

document.write(" 相差 " + years + "年" + months + "月" + days + "天 " + hours + "小时 " + minutes + " 分钟" + seconds + " 秒")

解决方案二：

jquery 计算日期
jquery计算时间差
两个日期时间差

解决方案三：

var date1 = new Date(2012, 4, 7, 11, 27); //开始时间
var date2 = new Date(2012, 4, 7, 12, 28); //结束时间
var date3 = date2.getTime() - date1.getTime(); //时间差的毫秒数
//计算相差的年数
var years = Math.floor(date3 / (12 * 30 * 24 * 3600 * 1000));
//计算相差的月数
var leave = date3 % (12 * 30 * 24 * 3600 * 1000);
var months = Math.floor(leave / (30 * 24 * 3600 * 1000));
//计算出相差天数
var leave0 = leave % (30 * 24 * 3600 * 1000);
var days = Math.floor(leave0 / (24 * 3600 * 1000));
//计算出小时数
var leave1 = leave0 % (24 * 3600 * 1000); //计算天数后剩余的毫秒数
var hours = Math.floor(leave1 / (3600 * 1000));
//计算相差分钟数
var leave2 = leave1 % (3600 * 1000); //计算小时数后剩余的毫秒数
var minutes = Math.floor(leave2 / (60 * 1000));
//计算相差秒数
var leave3 = leave2 % (60 * 1000); //计算分钟数后剩余的毫秒数
var seconds = Math.round(leave3 / 1000);

document.write(" 相差 " + years + "年" + months + "月" + days + "天 " + hours + "小时 " + minutes + " 分钟" + seconds + " 秒")
