var date = "2014-07-12 10:54:11";
我如何以2014年7月12日上午10:51的格式显示此内容? 有没有像
这样的功能var newDate = formatNewDate(date);
我可以从中获得日期时间为" 2014年7月12日上午10:51" ?

var d = new Date();
var month = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
var date = d.getDate() + " " + month[d.getMonth()] + ", " + d.getFullYear();
var time = d.toLocaleTimeString().toLowerCase();
console.log(date + " at " + time);
// 6 Jul, 2014 at 1:35:35 pm
或者你可以有一个功能
var my_date_format = function(d){
var month = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
var date = d.getDate() + " " + month[d.getMonth()] + ", " + d.getFullYear();
var time = d.toLocaleTimeString().toLowerCase();
return (date + " at " + time);
}(new Date());
用法:
console.log(my_date_format);
2nd solution
var my_date_format = function(input){
var d = new Date(Date.parse(input.replace(/-/g, "/")));
var month = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
var date = d.getDate() + " " + month[d.getMonth()] + ", " + d.getFullYear();
var time = d.toLocaleTimeString().toLowerCase().replace(/([\d]+:[\d]+):[\d]+(\s\w+)/g, "$1$2");
return (date + " " + time);
};
console.log(my_date_format("2014-07-12 11:28:13"));
// output 6 Jul, 2014 11:28 am
检查jsBin
Extra note:
所有浏览器都不支持某些日期格式!
// "2014/07/12" -> yyyy/mm/dd [IE, FF, Chrome]
// "07-12-2014" -> mm-dd-yyyy [IE, Chrome]
// "July 12, 2014"; -> mmmm dd, yyyy [IE, FF]
// "Jul 12, 2014"; -> mmm dd, yyyy [IE, FF]

已经制作了自定义日期字符串格式功能,您可以使用它。
var getDateString = function(date, format) {
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
getPaddedComp = function(comp) {
return ((parseInt(comp) < 10) ? ('0' + comp) : comp)
},
formattedDate = format,
o = {
"y+": date.getFullYear(), // year
"M+": months[date.getMonth()], //month
"d+": getPaddedComp(date.getDate()), //day
"h+": getPaddedComp((date.getHours() > 12) ? date.getHours() % 12 : date.getHours()), //hour
"H+": getPaddedComp(date.getHours()), //hour
"m+": getPaddedComp(date.getMinutes()), //minute
"s+": getPaddedComp(date.getSeconds()), //second
"S+": getPaddedComp(date.getMilliseconds()), //millisecond,
"b+": (date.getHours() >= 12) ? 'PM' : 'AM'
};
for (var k in o) {
if (new RegExp("(" + k + ")").test(format)) {
formattedDate = formattedDate.replace(RegExp.$1, o[k]);
}
}
return formattedDate;
};
现在假设你&#39; vs: -
var date = "2014-07-12 10:54:11",
objDate = Date.parse(date.replace(/-/g, "/"));;
所以要格式化这个日期,你要写: -
var formattedDate = getDateString(new Date(objDate ), "d M, y at h:m b")

是否有像
这样的功能
没有。你必须自己格式化。您有两个选择:解析字符串以创建Date对象并从中生成格式化字符串,或者只使用字符串的部分并重新格式化它。在这两种情况下,都假设您希望将其视为本地日期。
不要试图这样做:
var d = new Date('2014-07-12 10:54:11')
因为有些浏览器会将其视为UTC,有些浏览器会将其视为本地浏览器,而其他浏览器则根本无法解析它。以下内容将字符串转换为请求的格式,而不创建Date对象:
function formatDate(s){
var months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'];
var b = s.split(/\D+/);
return b[2] + ' ' + months[+b[1]] + ', ' + b[0] + ' at ' + (b[3]%12 || 12) +
':' + b[4] + ' ' + (b[3] < 12? 'am':'pm');
}
但是,如果由于某些其他原因需要创建Date对象,则以下内容可能有所帮助:
function formatDate(s){
function z(n){return (n<10?'0':'')+n}
var months = ['Jan','Feb','Mar','Apr','May','Jun',
'Jul','Aug','Sep','Oct','Nov','Dec'];
var b = s.split(/\D+/);
var d = new Date(b[0],--b[1],b[2],b[3],b[5],b[5]);
return d.getDate() + ' ' + months[d.getMonth()] + ', ' + d.getFullYear() +
' at ' + z(d.getHours()%12 || 12) + ':' + z(d.getMinutes()) +
' ' + (d.getHours() < 12? 'am':'pm');
}

function convertMysqldate(dateStr) { // Assuming input:2014-01-30 16:21:09
var t = dateStr.split(/[- :]/);
var monthNames = ["January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December"];
var year = t[0];
var month = monthNames[parseInt(t[1])];
var day = t[2];
var hourTmp = t[3];
var minute = t[4];
var seconds = t[5];
if (parseInt(hourTmp) > 12) {
var hour = parseInt(parseInt(hourTmp) – 12) + ‘:’ + minute + ‘:’ + seconds + ‘ PM’;
} else if (parseInt(hourTmp) === 12) {
hour = parseInt(hourTmp) + ‘:’ + minute + ‘:’ + seconds + ‘ PM’;
} else {
hour = parseInt(hourTmp) + ‘:’ + minute + ‘:’ + seconds + ‘ AM’;
}
return (hour + ‘<br>’ + day + ‘ ‘ + month + ‘ ‘ + year);
