复制代码 代码如下:
function dateFormat(date, format) {
var o = {
"M+": date.getMonth() + 1, //month
"d+": date.getDate(), //day
"h+": date.getHours(), //hour
"m+": date.getMinutes(), //minute
"s+": date.getSeconds(), //second
"q+": Math.floor((date.getMonth() + 3) / 3), //quarter
"S": date.getMilliseconds() //millisecond
};

//把yyyy替换成具体的年份
if (/(y+)/.test(format)) {
format = format.replace(RegExp.$1, (date.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 ? (("000" + o[k]).substr(("" + o[k]).length)) : ("00" + o[k]).substr(("" + o[k]).length));
}
}
return format;
}
