How to format time in js

var myDate = new Date();

myDate.getYear(); // 获取当前年份(2位) myDate.getFullYear(); // 获取完整的年份(4位,1970-????) myDate.getMonth(); // 获取当前月份(0-11,0代表1月) myDate.getDate(); // 获取当前日(1-31) myDate.getDay(); // 获取当前星期X(0-6,0代表星期天) myDate.getTime(); // 获取当前时间(从1970.1.1开始的毫秒数) myDate.getHours(); // 获取当前小时数(0-23) myDate.getMinutes(); // 获取当前分钟数(0-59) myDate.getSeconds(); // 获取当前秒数(0-59) myDate.getMilliseconds(); // 获取当前毫秒数(0-999) myDate.toLocaleDateString(); // 获取当前日期 var mytime=myDate.toLocaleTimeString(); // 获取当前时间 myDate.toLocaleString( ); // 获取日期与时间
3、时间的格式化
// 对Date的扩展,将 Date 转化为指定格式的String // 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符, // 年(y)可以用 1-4 个占位符,毫秒(S)只能用 1 个占位符(是 1-3 位的数字) // 例子: // (new Date()).Format("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423 // (new Date()).Format("yyyy-M-d h:m:s.S") ==> 2006-7-2 8:9:4.18 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; }
调用:
var time1 = new Date().Format("yyyy-MM-dd"); var time2 = new Date().Format("yyyy-MM-dd hh:mm:ss");
