javaScript中将时间戳转换成日期格式

 1 function DateFormt(time, format) {
 2         var testDate = new Date(time * 1000);
 3         var o =
 4     {
 5         "M+": testDate.getMonth() + 1,
 6         "d+": testDate.getDate(),
 7         "h+": testDate.getHours(),
 8         "m+": testDate.getMinutes(),
 9         "s+": testDate.getSeconds(),
10         "q+": Math.floor((testDate.getMonth() + 3) / 3),
11         "S": testDate.getMilliseconds()
12     }
13         if (/(y+)/.test(format)) {
14             format = format.replace(RegExp.$1, (testDate.getFullYear() + "").substr(4 - RegExp.$1.length));
15         }
16         for (var k in o) {
17             if (new RegExp("(" + k + ")").test(format)) {
18                 format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : ("00" + o[k]).substr(("" + o[k]).length));
19             }
20         }
21         return format;
22     }
