在PHP中,我可以使用日期(日期)并做我想要做的事情......
JS/jQuery是否有类似之处?
没有人在时间上任职,与时俱进。
http://momentjs.com/“rel=“noreferer”http://momentjs.com/
Just did a benchmark and found it parses much faster than date.js, but formatting and manipulating is slower. For one-liners it d execute faster than date.js due to the faster parsing.
一些使用实例:
// Simulates ajax response
var data = { someDate: "2023-08-23 11:52:39" }
// .unix() converts to Unix timestamp: 1692816759
moment(data.someDate).unix();
// Displaying it in a readable format
// Aug 23, 11:52 AM
moment("2023-08-23 11:52:39").format( MMM D, hh:mm A );
// Now
moment();
// Support for manipulation and chaining
moment().add( days , 7).subtract( months , 1).hours(15).minutes(0).seconds(0);
http://www.datejs.com/“Datejs/strong>。
据作者称,)是“相当于PHP日期的 Java本”。 因此,如果你回顾一下,让它尝试。

// note: Uses global: php_js to store the default timezone
// note: Although the function potentially allows timezone info (see notes), it currently does not set
// note: per a timezone specified by date_default_timezone_set(). Implementers might use
// note: this.php_js.currentTimezoneOffset and this.php_js.currentTimezoneDST set by that function
// note: in order to adjust the dates in this function (or our other date functions!) accordingly
// example 1: date( H:m:s \m \i\s \m\o\n\t\h , 1062402400);
// returns 1: 09:09:40 m is month
// example 2: date( F j, Y, g:i a , 1062462400);
// returns 2: September 2, 2003, 2:26 am
// example 3: date( Y W o , 1062462400);
// returns 3: 2003 36 2003
// example 4: x = date( Y m d , (new Date()).getTime()/1000);
// example 4: (x+ ).length == 10 // 2009 01 09

if you don t need full timezone support (North American timezones only),
I wrote a very fast, fully compatible phpdate()
and matching gmdate()
that exactly emulate the php date and gmdate functions. (The unit tests
have a fuzz test that format random timestamps and compare against php;
I ve run several hundred thousand timestamps while testing.)
I wrote it for nodejs, but if someone helps, I d be willing to port
it to pure js.
