字符串转换成Date
1 new Date("2006/01/12 13:14:15")

2
var s = "2010-09-11";
var d = new Date(s.replace(/-/g,"/"));
alert(d)

把Date()对象格式化成字符串
Date.prototype.format = function(format) {
/
eg:format="yyyy-MM-dd hh:mm:ss";
*/
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 time1 = new Date().format("yyyy-MM-dd HH:mm:ss");

Fri Oct 31 18:00:00 UTC+0800 2008 格式日期数据转换标准日期格式
function Todate(num) {
//Fri Oct 31 18:00:00 UTC+0800 2008
num = num + ""; //给字符串后就一个空格
var date = "";
var month = new Array();
month["Jan"] = 1; month["Feb"] = 2; month["Mar"] = 3; month["Apr"] = 4;
month["May"] = 5; month["Jan"] = 6; month["Jul"] = 7; month["Aug"] = 8;
month["Sep"] = 9; month["Oct"] = 10; month["Nov"] = 11; month["Dec"] = 12;
var week = new Array();
week["Mon"] = "一"; week["Tue"] = "二"; week["Wed"] = "三"; week["Thu"] = "四";
week["Fri"] = "五"; week["Sat"] = "六"; week["Sun"] = "日";
str = num.split(" "); //根据空格组成数组
date = str[5] + "-"; //就是在2008的后面加一个“-”
//通过修改这里可以得到你想要的格式
date = date + month[str[1]] + "-" + str[2] + " " + str[3];
//date=date+" 周"+week[str[0]];
return date;
