//时间格式化 Date.prototype.Format = function (fmt) { var o = { "M+": this.getMonth() + 1, "d+": this.getDate(), "h+": this.getHours(), "m+": this.getMinutes(), "s+": this.getSeconds(), "q+": Math.floor((this.getMonth() + 3) / 3), "S": this.getMilliseconds() }; 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; }
