jquery 格式化时间

其实jquery 没有格式化时间的函数的，一般情况下都是这样来的：

var d=new Date(date);

var formatdate=d.getMonth()+"月"+d.getDay()+"日 "+d.getHours()+"时"+d.getMinutes()+"分"+d.getSeconds()+"秒";

document.write(formatdate);

如果一定要用jquery来格式化时间的话要先导入一个date.format.js就可以了。

date.format.js库内容：

var dateFormat = function () {

var token = /d{1,4}|m{1,4}|yy(?:yy)?|([HhMsTt])\1?|[LloSZ]|"[^"]*"|'[^']*'/g,

timezone = /\b(?:[PMCEA][SDP]T|(?:Pacific|Mountain|Central|Eastern|Atlantic) (?:Standard|Daylight|Prevailing) Time|(?:GMT|UTC)(?:[- ]\d{4})?)\b/g,

timezoneClip = /[^- \dA-Z]/g,

pad = function (val, len) {

val = String(val);

len = len || 2;

while (val.length len) val = "0" val;

return val;

};

// Regexes and supporting functions are cached through closure

return function (date, mask, utc) {

var dF = dateFormat;

// You can't provide utc if you skip other args (use the "UTC:" mask prefix)

if (arguments.length == 1 Object.prototype.toString.call(date) == "[object String]" !/\d/.test(date)) {

mask = date;

date = undefined;

}

// Passing date through Date applies Date.parse, if necessary

date = date ? new Date(date) : new Date;

if (isNaN(date)) throw SyntaxError("invalid date");

mask = String(dF.masks[mask] || mask || dF.masks["default"]);

// Allow setting the utc argument via the mask

if (mask.slice(0, 4) == "UTC:") {

mask = mask.slice(4);

utc = true;

}

var _ = utc ? "getUTC" : "get",

d = date[_ "Date"](),

D = date[_ "Day"](),

m = date[_ "Month"](),

y = date[_ "FullYear"](),

H = date[_ "Hours"](),

M = date[_ "Minutes"](),

s = date[_ "Seconds"](),

L = date[_ "Milliseconds"](),

o = utc ? 0 : date.getTimezoneOffset(),

flags = {

d: d,

dd: pad(d),

ddd: dF.i18n.dayNames[D],

dddd: dF.i18n.dayNames[D 7],

m: m 1,

mm: pad(m 1),

mmm: dF.i18n.monthNames[m],

mmmm: dF.i18n.monthNames[m 12],

yy: String(y).slice(2),

yyyy: y,

h: H % 12 || 12,

hh: pad(H % 12 || 12),

H: H,

HH: pad(H),

M: M,

MM: pad(M),

s: s,

ss: pad(s),

l: pad(L, 3),

L: pad(L 99 ? Math.round(L / 10) : L),

t: H 12 ? "a" : "p",

tt: H 12 ? "am" : "pm",

T: H 12 ? "A" : "P",

TT: H 12 ? "AM" : "PM",

Z: utc ? "UTC" : (String(date).match(timezone) || [""]).pop().replace(timezoneClip, ""),

o: (o 0 ? "-" : " ") pad(Math.floor(Math.abs(o) / 60) * 100 Math.abs(o) % 60, 4),

S: ["th", "st", "nd", "rd"][d % 10 3 ? 0 : (d % 100 - d % 10 != 10) * d % 10]

};

return mask.replace(token, function ($0) {

return $0 in flags ? flags[$0] : $0.slice(1, $0.length - 1);

});

};

}();

// Some common format strings

dateFormat.masks = {

"default": "ddd mmm dd yyyy HH:MM:ss",

shortDate: "m/d/yy",

mediumDate: "mmm d, yyyy",

longDate: "mmmm d, yyyy",

fullDate: "dddd, mmmm d, yyyy",

shortTime: "h:MM TT",

mediumTime: "h:MM:ss TT",

longTime: "h:MM:ss TT Z",

isoDate: "yyyy-mm-dd",

isoTime: "HH:MM:ss",

isoDateTime: "yyyy-mm-dd'T'HH:MM:ss",

isoUtcDateTime: "UTC:yyyy-mm-dd'T'HH:MM:ss'Z'"

};

// Internationalization strings

dateFormat.i18n = {

dayNames: [

"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat",

"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"

],

monthNames: [

"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec",

"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"

]

};

// For convenience...

Date.prototype.format = function (mask, utc) {

return dateFormat(this, mask, utc);

};

首先转化成日期类型：var date = eval_r(commentList[i].CreateDateTime.replace(/\/Date\((\d )\)\//gi, "new Date($1)"));

然后再调用js库方法：

dateFormat(date, "yyyy-MM-dd hh:mm:ss");

jQuery如何实现简单日期格式化功能

Date.prototype.Format = function (fmt) { //author: meizz

var o = {

"M+": this.getMonth() + 1, //月份

"d+": this.getDate(), //日

"h+": this.getHours(), //小时

"m+": this.getMinutes(), //分

"s+": this.getSeconds(), //秒

"q+": Math.floor((this.getMonth() + 3) / 3), //季度

"S": this.getMilliseconds() //毫秒

};

if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));

for (var k in o)

if (new RegExp("(" + k + ")").test(fmt)) fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));

return fmt;

}

$(function(){

var date=new Date();

alert(JSON.stringify(date.Format("yyyy年MM月dd hh:mm:ss")));

})

jquery json解析action中返回的数据日期老是1459688615000 怎么格式化

jquery json解析action中返回的数据日期老是1459688615000需要抓换成可读的日期格式的方法：

1、定义一个转换函数：

function formatDate(dateVal) {

var newDate = new Date(dateVal);

var sMonth = padValue(newDate.getMonth() + 1);

var sDay = padValue(newDate.getDate());

var sYear = newDate.getFullYear();

var sHour = newDate.getHours();

var sMinute = padValue(newDate.getMinutes());

var sAMPM = "AM";

var iHourCheck = parseInt(sHour);

if (iHourCheck 12) {

   sAMPM = "PM";

   sHour = iHourCheck - 12;

}

else if (iHourCheck === 0) {

   sHour = "12";

}

sHour = padValue(sHour);

return sMonth + "-" + sDay + "-" + sYear + " " + sHour + ":" + sMinute + " " + sAMPM;

}

2、设置格式填充

function padValue(value) {

return (value 10) ? "0" + value : value;

}

3、转换结果：

输入：1459688615000

输出：

jquery里，怎么格式化时间

有好几种日期表达形式

其中一种

var time1 = new Date().format("yyyy-MM-dd HH:mm:ss");
