Jquery 时间类型格式化

JS代码

使用方式如下：

var now = new Date();now.format("m/dd/yy");// Returns, e.g., 6/09/07// Can also be used as a standalone functiondateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT");// Saturday, June 9th, 2007, 5:46:21 PM// You can use one of several named masksnow.format("isoDateTime");// 2007-06-09T17:46:21// ...Or add your owndateFormat.masks.hammerTime = 'HH:MM! "Can\'t touch this!"';now.format("hammerTime");// 17:46! Can't touch this!// When using the standalone dateFormat function,// you can also provide the date as a stringdateFormat("Jun 9 2007", "fullDate");// Saturday, June 9, 2007// Note that if you don't include the mask argument,// dateFormat.masks.default is usednow.format();// Sat Jun 09 2007 17:46:21// And if you don't include the date argument,// the current date and time is useddateFormat();// Sat Jun 09 2007 17:46:22// You can also skip the date argument (as long as your mask doesn't// contain any numbers), in which case the current date/time is useddateFormat("longTime");// 5:46:22 PM EST// And finally, you can convert local time to UTC time. Either pass in// true as an additional argument (no argument skipping allowed in this case):dateFormat(now, "longTime", true);now.format("longTime", true);// Both lines return, e.g., 10:46:21 PM UTC// ...Or add the prefix "UTC:" to your mask.now.format("UTC:h:MM:ss TT Z");// 10:46:21 PM UTC
