Date()没有格式化函数,除非你自己写了一个。在这种情况下,错误可能在此函数中。
format() 调用会产生错误,但timenow
无论如何您都没有使用。我假设您打算将值设置为 timenow。
你可以借用我的格式方法,但它不包括 UTC、TT 或 Z。
Date.prototype.format = function (sFormat, twelve) {
// Returns: A string version of the date.
// Usage: date_instance.format("d mmm yy hh:nn:ss ap") or
// date_instance.format("dddd dd mmmm hh:nn", true)
// Defaults to YYYY/MM/DD.
// twelve == true for a 12hr clock, or just AP or ap within
// sFormat (for AM/PM or am/pm).
// Use z or zzz for milliseconds and xx for suffixes (st, nd, etc.).
var MonthNames = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"];
var DayNames = [ "Sunday", "Monday", "Tueday", "Wednesday", "Thursday",
"Friday", "Saturday" ];
var dDate = this || new Date(),
D = dDate.getDate(), DDDD = DayNames[dDate.getDay()],
DDD = DDDD.substr(0,3),
M = dDate.getMonth()+1, MMMM = MonthNames[dDate.getMonth()],
MMM = MMMM.substr(0,3),
YYYY = dDate.getFullYear(), YY = ('' + YYYY).substr(2, 2),
H = dDate.getHours(), N = dDate.getMinutes(), S = dDate.getSeconds(),
Z = dDate.getMilliseconds(),
ap = (H > 11) ? "pm" : "am",
// pad with leading zeros, if required
DD = ( D < 10 ? "0" : "" ) + D,
MM = ( M < 10 ? "0" : "" ) + M,
NN = ( N < 10 ? "0" : "" ) + N,
SS = ( S < 10 ? "0" : "" ) + S,
ZZZ = ( Z < 10 ? "00" : (Z < 100 ? "0" : "") ) + Z, XX;
var AP = (sFormat && (sFormat.toUpperCase().indexOf('AP')+1)) ?
((sFormat.indexOf('ap')+1) ? ap : ap.toUpperCase()) : '';
if (twelve || AP) {
H = (H < 12) ? (H || 12) : ((H - 12) || 12);
}
var HH = ( H < 10 ? "0" : "" ) + H;
XX = (D == 1 || D == 21 || D == 31) ? "st" :
((D == 2 || D == 22) ? "nd" : ((D == 3 || D == 23) ? "rd" : "th"));
sFormat = ( sFormat ) ? sFormat.toUpperCase() : 'YYYY/MM/DD';
var sParsed = sFormat.replace(/D{1,4}|M{1,4}|Y{2,4}|H{1,2}|N{1,2}|S{1,2}|Z{1,3}|XX|AP/g,
function (m) {
try {
return eval(m);
} catch (e) {
return '';
}
});
return sParsed;
};
我用“nn”表示分钟,用“mm”表示月份。
