How to convert UTC format time to local format with JS_javascript skills

复制代码 代码如下:

Date.prototype.format = function (format) {
var o = {
"M ": this.getMonth() 1, //month
"d ": this.getDate(), //day
"h ": this.getHours(), //hour
"m ": this.getMinutes(), //minute
"s ": this.getSeconds(), //second
"q ": Math.floor((this.getMonth() 3) / 3), //quarter
"S": this.getMilliseconds() //millisecond
}
if (/(y )/.test(format)) format = format.replace(RegExp.$1,
(this.getFullYear() "").substr(4 - RegExp.$1.length));
for (var k in o) if (new RegExp("(" k ")").test(format))
format = format.replace(RegExp.$1,
RegExp.$1.length == 1 ? o[k] :
("00" o[k]).substr(("" o[k]).length));
return format;
}

var TempDate = new Date();

TempDate.toLocaleDateString()//2013年9月4日
