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");

Q1: jquery里，怎么格式化时间
jquery里格式化时间需要自定义函数，举例如下：
1、定义函数formatDate，这里传入一个value参数
function formatDate(value){
if(value){ 如果value不为空
Number.prototype.padLeft = function(base,chr){ 嵌套调用填充函数padleft
var len = (String(base || 10).length - String(this).length)+1;获取value值的长度，如果长度大于0，就创建一个同等长度的数组
return len 0? new Array(len).join(chr || '0')+this : this;
}
var d = new Date(value),创建一个当前日期对象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(),把小时格式化填充
d.getMinutes().padLeft(),把分钟格式化填充
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时间
}
}
2、调用方法举例：
var startDate = "20150618090012"
var result = formatDate(startDate);
3、输出结果：
2015/06/18 09:00:12
Q2: jquery时间戳怎么转成日期格式
这个不能直接转换。只能自己编写。
下面是简单的例子。并有基本注释：
(function($) {
$.extend({
myTime: {
/**
* 当前时间戳
* @return int unix时间戳(秒)
*/
CurTime: function(){
return Date.parse(new Date())/1000;
},
/**
* 日期 转换为 Unix时间戳
* @param string 2014-01-01 20:20:20 日期格式
* @return int unix时间戳(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;
},
/**
* 时间戳转换日期
* @param int unixTime 待时间戳(秒)
* @param bool isFull 返回完整时间(Y-m-d 或者 Y-m-d H:i:s)
* @param int timeZone 时区
*/
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);
Q3: jQuery的时间格式问题，怎么解决
// 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（精简）
function DT_dateTimeSimpleFmatter(td, cellData, rowData, row, col) {
$(td).html(cellData?formatDate(new Date(cellData),'yy/MM/dd HH:mm'):'--');
}
