其實jquery 沒有格式化時間的函數(shù)的,一般情況下都是這樣來的:

var d=new Date(date);
var formatdate=d.getMonth()+"月"+d.getDay()+"日 "+d.getHours()+"時"+d.getMinutes()+"分"+d.getSeconds()+"秒";
document.write(formatdate);
如果一定要用jquery來格式化時間的話要先導入一個date.format.js就可以了。
date.format.js庫內容:
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);
};
首先轉化成日期類型:var date = eval_r(commentList[i].CreateDateTime.replace(/\/Date\((\d )\)\//gi, "new Date($1)"));
然后再調用js庫方法:
dateFormat(date, "yyyy-MM-dd hh:mm:ss");
// 格式化日期
function DT_dateTimeFmatter(td, cellData, rowData, row, col) {
$(td).html(cellData?formatDate(new Date(cellData),'yyyy/MM/dd HH:mm:ss'):'--');
}
// 格式化日期(年月日)
function DT_dateFmatter(td, cellData, rowData, row, col) {
$(td).html(cellData?formatDate(new Date(cellData),'yyyy/MM/dd'):'--');
}
// 格式化日期(精簡)
function DT_dateTimeSimpleFmatter(td, cellData, rowData, row, col) {
$(td).html(cellData?formatDate(new Date(cellData),'yy/MM/dd HH:mm'):'--');
}
這個不能直接轉換。只能自己編寫。
下面是簡單的例子。并有基本注釋:
(function($)?{
$.extend({
myTime:?{
/**
*?當前時間戳
*?@return?int????????unix時間戳(秒)??
*/
CurTime:?function(){
return?Date.parse(new?Date())/1000;
},
/**??????????????
*?日期?轉換為?Unix時間戳
*?@param?string?2014-01-01?20:20:20??日期格式??????????????
*?@return?int????????unix時間戳(秒)??????????????
*/
DateToUnix:?function(string)?{
var?f?=?string.split('?',?2);
var?d?=?(f[0]???f[0]?:?'').split('-',?3);
var?t?=?(f[1]???f[1]?:?'').split(':',?3);
return?(new?Date(
parseInt(d[0],?10)?||?null,
(parseInt(d[1],?10)?||?1)?-?1,
parseInt(d[2],?10)?||?null,
parseInt(t[0],?10)?||?null,
parseInt(t[1],?10)?||?null,
parseInt(t[2],?10)?||?null
)).getTime()?/?1000;
},
/**??????????????

*?@param?int?unixTime????待時間戳(秒)??????????????
*?@param?bool?isFull????返回完整時間(Y-m-d?或者?Y-m-d?H:i:s)??????????????
*?@param?int??timeZone???時區(qū)??????????????
*/
UnixToDate:?function(unixTime,?isFull,?timeZone)?{
if?(typeof?(timeZone)?==?'number')
{
unixTime?=?parseInt(unixTime)?+?parseInt(timeZone)?*?60?*?60;
}
var?time?=?new?Date(unixTime?*?1000);
var?ymdhis?=?"";
ymdhis?+=?time.getUTCFullYear()?+?"-";
ymdhis?+=?(time.getUTCMonth()+1)?+?"-";
ymdhis?+=?time.getUTCDate();
if?(isFull?===?true)
{
ymdhis?+=?"?"?+?time.getUTCHours()?+?":";
ymdhis?+=?time.getUTCMinutes()?+?":";
ymdhis?+=?time.getUTCSeconds();
}
return?ymdhis;
}
}
});
})(jQuery);
在javascript中直接輸出Date得到的結果是這樣的:
function date(){
var date = new Date();
alert(date);
}
結果是:Mon Jun 15 15:30:46 UTC+0800 2009
得到new Date()型中各個時間級別(年、月、日、時、分、秒)的數(shù):
function date(){
var date = new Date();
var year = date.getFullYear();
var month = date.getMonth()+1; //js從0開始取
var date1 = date.getDate();
var hour = date.getHours();
var minutes = date.getMinutes();
var second = date.getSeconds();
alert(date+" | "+year+"年"+month+"月"+date1+"日"+hour+"時"+minutes +"分"+second+"秒" );
}
得到的結果就是:Mon Jun 15 15:44:50 UTC+0800 2009 | 2009年6月15日15時44分50秒
推薦一個JavaScript常用函數(shù)庫:
jutils
其中的 formatDate?函數(shù)(javascript時間戳轉換),支持自定義格式,可以顯示年,月,周,日,時,分,秒多種形式的日期和時間。
例:
var?date?=?jutils.formatDate(new?Date(1567564136*1000),"YYYY-MM-DD?HH:ii:ss");
console.log(date);
//?2019-09-04?10:28:56
還可以自定義返回格式,更多用法可以參照:
js將時間戳轉為日期格式
部分源碼的截圖:
js時間戳轉換年月日
jquery里格式化時間需要自定義函數(shù),舉例如下:
1、定義函數(shù)formatDate,這里傳入一個value參數(shù)
function formatDate(value){
if(value){ 如果value不為空
Number.prototype.padLeft = function(base,chr){ 嵌套調用填充函數(shù)padleft
var len = (String(base || 10).length - String(this).length)+1;獲取value值的長度,如果長度大于0,就創(chuàng)建一個同等長度的數(shù)組
return len 0? new Array(len).join(chr || '0')+this : this;
}
var d = new Date(value),創(chuàng)建一個當前日期對象d
dformat = [ (d.getMonth()+1).padLeft(),把月格式化填充
d.getDate().padLeft(),把日格式化填充
d.getFullYear()].join('/')+把年格式化填充
' ' +
[ d.getHours().padLeft(),把小時格式化填充
d.getMinutes().padLeft(),把分鐘格式化填充
d.getSeconds().padLeft()].join(':');把秒格式化填充
return dformat; 最后返回格式化好的日期和時間
}
}
2、調用方法舉例:
var startDate = "20150618090012"
var result = formatDate(startDate);
3、輸出結果:
2015/06/18 09:00:12
