javascript日期格式化方法汇总

// 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) ?
