在前人的基础上改进的，原来的代码无法运行。先能用吧。
Date.prototype.format = function (mask) {
var d = this;
var zeroize = function (value, length) {
if (!length) length = 2;
value = String(value);
for (var i = 0, zeros = ‘‘; i < (length - value.length); i++) {
zeros += ‘0‘;
}
return zeros + value;
};
return mask.replace(/(?:d{1,4}|M{1,4}|yy(?:yy)|H{1,2}|h{1,2}|m{1,2}|s{1,2}|[lLZ]|tt|TT)/g, function ($0) {
switch ($0) {
case ‘d‘:
return d.getDate();
case ‘dd‘:
return zeroize(d.getDate());
case ‘ddd‘:
return [‘Sun‘, ‘Mon‘, ‘Tue‘, ‘Wed‘, ‘Thr‘, ‘Fri‘, ‘Sat‘][d.getDay()];
case ‘dddd‘:
return [‘Sunday‘, ‘Monday‘, ‘Tuesday‘, ‘Wednesday‘, ‘Thursday‘, ‘Friday‘, ‘Saturday‘][d.getDay()];
case ‘M‘:
return d.getMonth() + 1;
case ‘MM‘:
return zeroize(d.getMonth() + 1);
case ‘MMM‘:
return [‘Jan‘, ‘Feb‘, ‘Mar‘, ‘Apr‘, ‘May‘, ‘Jun‘, ‘Jul‘, ‘Aug‘, ‘Sep‘, ‘Oct‘, ‘Nov‘, ‘Dec‘][d.getMonth()];
case ‘MMMM‘:
return [‘January‘, ‘February‘, ‘March‘, ‘April‘, ‘May‘, ‘June‘, ‘July‘, ‘August‘, ‘September‘, ‘October‘, ‘November‘, ‘December‘][d.getMonth()];
case ‘yy‘:
return String(d.getFullYear()).substr(2);
case ‘yyyy‘:
return d.getFullYear();
case ‘h‘:
return d.getHours() % 12 || 12;
case ‘hh‘:
return zeroize(d.getHours() % 12 || 12);
case ‘H‘:
return d.getHours();
case ‘HH‘:
return zeroize(d.getHours());
case ‘m‘:
return d.getMinutes();
case ‘mm‘:
return zeroize(d.getMinutes());
case ‘s‘:
return d.getSeconds();
case ‘ss‘:
return zeroize(d.getSeconds());
case ‘l‘:
return zeroize(d.getMilliseconds(), 3);
case ‘L‘:
var m = d.getMilliseconds();
if (m > 99) m = Math.round(m / 10);
return zeroize(m);
case ‘tt‘:
return d.getHours() < 12 ? ‘am‘ : ‘pm‘;
case ‘TT‘:
return d.getHours() < 12 ? ‘AM‘ : ‘PM‘;
case ‘Z‘:
return d.toUTCString().match(/[A-Z]+$/);
default:// Return quoted strings with the surrounding quotes removed
return $0.substr(1, $0.length - 2);
}
});
};
调用方法：
new Date().format("yyyy-mm-dd HH:mm:ss l tt TT");
不谢！
