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");
