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' ); |
