JS中常用的几种时间格式处理-【笔记整理】

//此处整理点平时常用到的时间格式处理方法

-------------------------------------------

 //时间格式化函数
 Date.prototype.format = function (format) {
     var o = {
         "M+": this.getMonth() + 1, //month
         "d+": this.getDate(), //day
         "h+": this.getHours(), //hour
         "m+": this.getMinutes(), //minute
         "s+": this.getSeconds(), //second
         "q+": Math.floor((this.getMonth() + 3) / 3), //quarter
         "S": this.getMilliseconds() //millisecond
     }
     if (/(y+)/.test(format)) {
         format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
     }
     for (var k in o) {
         if (new RegExp("(" + k + ")").test(format)) {
             format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : ("00" + o[k]).substr(("" + o[k]).length));
         }
     }
     return format;
 }

 //可将  var  time = new date();转换成 2016-08-03 18:30:00 格式//消除浏览器之间差异
 function DateHandle(objDate) {
     objDate = new Date(); //创建一个日期对象表示当前时间
     var year = objDate.getFullYear();   //四位数字年
     var month = objDate.getMonth() + 1; //getMonth()返回的月份是从0开始的，还要加1
     var date = objDate.getDate();
     var hours = objDate.getHours();
     var minutes = objDate.getMinutes();
     var seconds = objDate.getSeconds();
     var date = year + "-" + month + "-" + date + " " + hours + ":" + minutes + ":" + seconds;
     return date;
 }

 //+---------------------------------------------------
 //| 字符串转成日期类型
 //| 格式 MM/dd/YYYY MM-dd-YYYY YYYY/MM/dd YYYY-MM-dd
 //+---------------------------------------------------
 function StringToDate(DateStr) {

     var converted = Date.parse(DateStr);
     var myDate = new Date(converted);
     if (isNaN(myDate)) {
         var arys = DateStr.split('-');
         myDate = new Date(arys[0], --arys[1], arys[2]);
     }
     return myDate;
 }

 //+---------------------------------------------------
 //| 比较日期差 dtEnd 格式为日期型或者有效日期格式字符串
 //+---------------------------------------------------
 Date.prototype.DateDiff = function (strInterval, dtEnd) {
     var dtStart = this;
     if (typeof dtEnd == 'string')//如果是字符串转换为日期型
     {
         dtEnd = StringToDate(dtEnd);
     }
     switch (strInterval) {
         case 's': return parseInt((dtEnd - dtStart) / 1000);
         case 'n': return parseInt((dtEnd - dtStart) / 60000);
         case 'h': return parseInt((dtEnd - dtStart) / 3600000);
         case 'd': return parseInt((dtEnd - dtStart) / 86400000);
         case 'w': return parseInt((dtEnd - dtStart) / (86400000 * 7));
         case 'm': return (dtEnd.getMonth() + 1) + ((dtEnd.getFullYear() - dtStart.getFullYear()) * 12) - (dtStart.getMonth() + 1);
         case 'y': return dtEnd.getFullYear() - dtStart.getFullYear();
     }
 }

 //时间转换//加数字颜色/样式
　　//time 单位 秒
 function secondToDateAndStyle(time) {
     time = parseInt(time);
     if (null != time && "" != time) {
         if (time > 60 && time < 60 * 60) {
             time = "<span style=\"color:#FF6600;\">" + parseInt(time / 60.0) + "</span>" + "分" + "<span style=\"color:#FF6600;\">" + parseInt((parseFloat(time / 60.0) - parseInt(time / 60.0)) * 60) + "</span>" + "秒";
         } else if (time >= 60 * 60 && time < 60 * 60 * 24) {
             time = "<span style=\"color:#FF6600;\">" + parseInt(time / 3600.0) + "</span>" + "时" + "<span style=\"color:#FF6600;\">" + parseInt((parseFloat(time / 3600.0) - parseInt(time / 3600.0)) * 60) + "</span>" + "分" + "<span style=\"color:#FF6600;\">" + parseInt((parseFloat((parseFloat(time / 3600.0) - parseInt(time / 3600.0)) * 60) - parseInt((parseFloat(time / 3600.0) - parseInt(time / 3600.0)) * 60)) * 60) + "</span>" + "秒";
         } else {
             time = "<span style=\"color:#FF6600;\">" + parseInt(time) + "</span>" + "秒";
         }
     } else {
         time = "<span style=\"color:#FF6600;\">0</span>秒";
     }
     return time;
 }

 //时间比较函数
 function CompareTime(Time1, Time2) {
     var start = new Date(Time1.replace("-", "/").replace("-", "/"));
     var end = new Date(Time2.replace("-", "/").replace("-", "/"));
     if (end <= start) {
         //后者小于前者返回false
         return false;
     }
     return true;//后者大于前者返回true
 }
