自定义js方法 (格式化时间)

代码
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;
}
