JavaScript对时间格式处理的详解

// 说明：将C#时间戳，格式为：/Date(-62135596800000)，转换为js时间。// 参数：timeSpan 字符串 例如：'/Date(-62135596800000)'// 结果：JS的Datevar parseDate = function(timeSpan)
{ var timeSpan = timeSpan.replace('Date','').replace('(','').replace(')','').replace(/\//g,''); var d = new Date(parseInt(timeSpan)); return d;
};

// 说明：JS时间Date格式化参数// 参数：格式化字符串如：'yyyy-MM-dd HH:mm:ss'// 结果：如2016-06-01 10:09:00Date.prototype.Format = function (fmt) { //author: meizz 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() }; var year = this.getFullYear(); var yearstr = year + ''; yearstr = yearstr.length >= 4 ? yearstr : '0000'.substr(0, 4 - yearstr.length) + yearstr; if (/(y+)/.test(fmt)) fmt = fmt.replace(RegExp.$1, (yearstr + "").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;}

<script>
var dt=new Date();
var year=dt.getFullYear();
var month=dt.getMonth()+1;
var date=dt.getDate();
var day=dt.getDay();
var dayColl=['星期一','星期二','星期三','星期四','星期五','星期六','星期日'];
var riqi=year+"年"+month+"月"+date+"日";
var xingqi=dayColl[day-1];
$(function(){
$("#date").html(riqi);
$("#date").next().html(xingqi);
});
</script>
