javascript好用的格式化时间函数
代码
1 Date.prototype.format = function(format)
2 {
3 var o = {
4 "M+" : this.getMonth()+1, //month
5 "d+" : this.getDate(), //day
6 "h+" : this.getHours(), //hour
7 "m+" : this.getMinutes(), //minute
8 "s+" : this.getSeconds(), //second
9 "q+" : Math.floor((this.getMonth()+3)/3), //quarter
10 "S" : this.getMilliseconds() //millisecond
11 }
12 if(/(y+)/.test(format)) format=format.replace(RegExp.$1,
13 (this.getFullYear()+"").substr(4 - RegExp.$1.length));
14 for(var k in o)if(new RegExp("("+ k +")").test(format))
15 format = format.replace(RegExp.$1,
16 RegExp.$1.length==1 ? o[k] :
17 ("00"+ o[k]).substr((""+ o[k]).length));
18 return format;
19 }
20
2 {
3 var o = {
4 "M+" : this.getMonth()+1, //month
5 "d+" : this.getDate(), //day
6 "h+" : this.getHours(), //hour
7 "m+" : this.getMinutes(), //minute
8 "s+" : this.getSeconds(), //second
9 "q+" : Math.floor((this.getMonth()+3)/3), //quarter
10 "S" : this.getMilliseconds() //millisecond
11 }
12 if(/(y+)/.test(format)) format=format.replace(RegExp.$1,
13 (this.getFullYear()+"").substr(4 - RegExp.$1.length));
14 for(var k in o)if(new RegExp("("+ k +")").test(format))
15 format = format.replace(RegExp.$1,
16 RegExp.$1.length==1 ? o[k] :
17 ("00"+ o[k]).substr((""+ o[k]).length));
18 return format;
19 }

调用的方法
var t=showtime = new Date().format("yyyy-MM-dd hh:mm:ss");
document.write(t)
