JS常用的方法

1.时间戳转换

 //时间戳(有Date和无Date的都可)转换为日期 “2016年5月30日 10:29:30   2016-05-20 09:11”
 function TimeConversion(timeStamp,type) {
     if (timeStamp) {
         if (timeStamp.indexOf('Date') > -1) {
             var dtime = timeStamp.substring(6, timeStamp.length - 2);
             var newDate = new Date();
             newDate.setTime(dtime);
             var year = newDate.getFullYear();
             var month = newDate.getMonth() + 1;
             var data = newDate.getDate();
             var hour = '0' + newDate.getHours();
             hour = hour.substring(hour.length - 2)
             var minute = '0' + newDate.getMinutes();
             minute = minute.substring(minute.length - 2)
             var second = '0' + newDate.getSeconds();
             second = second.substring(second.length - 2)
             var s = "";
             if (type && type == 1) {
                 s = year + "-" + month + "-" + data + "  " + hour + ":" + minute;
             }
             else {
                 s = year + "年" + month + "月" + data + "日  " + hour + ":" + minute + ":" + second;
             }

             return s;
         }
         else {
             var dt = timeStamp.split(' ');
             var s = dt;
             if (dt.length > 1) {
                 var date = dt[0].split('/');
                 var time = dt[1].split(':');
                 var hour = '0' + time[0];
                 hour = hour.substring(hour.length - 2);
                 if (type && type == 1) {
                     s = date[0] + "-" + date[1] + "-" + date[2] + "  " + hour + ":" + time[1];
                 }
                 else {
                     s = date[0] + "年" + date[1] + "月" + date[2] + "日  " + hour + ":" + time[1] + ":" + time[2];
                 }
             }
             return s;
         }
