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; |
} |
以上代码必须先声明,然后在使用。使用方法: |
var d =new Date().format('yyyy-MM-dd'); |
