var data = new Date();		
document.write(data +"
");	//显示结果因浏览器而异

//两个静态方法

//Date.parse();
document.write(Date.parse("1/31/2016") +"
");//返回毫秒数

var data2 = new Date(Date.parse("1/31/2016"));
document.write(data2 +"
");

var data3 = new Date("1/31/2016");	//Date.parse()会被后台调用
document.write(data3 +"
");

//Date.UTC();	
var data4 = new Date(Date.UTC(2016, 3, 3, 17, 4, 6));	//月加1，时加8
document.write(data4 +"
");

var data5 = new Date(2016, 3, 3, 17, 4, 6);				//只有月加1
document.write(data5 +"
");

//通用方法
var cup = new Date(2016,1,31,16,42,16);
document.write(cup +"
");						//Wed Mar 02 2016 16:42:16 GMT+0800
document.write(cup.toString() +"
");				//Wed Mar 02 2016 16:42:16 GMT+0800
document.write(cup.toLocaleString() +"
");		//2016/3/2 下午4:42:16(ps：谷歌返回和上面一样)
document.write(cup.valueOf() +"
");				//1456908136000

//格式化
var suger = new Date(2016,0,31,16,42,16);
document.write(suger.toDateString() +"
");
document.write(suger.toTimeString() +"
");
document.write(suger.toLocaleDateString() +"
");
document.write(suger.toLocaleTimeString() +"
");
document.write(suger.toUTCString() +"
");

//组件方法
var face = new Date(2016,0,31,16,42,16);
document.write(face.getTime() +"
");				//获取日期的毫秒数
//face.setTime(1456908136000)						//设置日期毫秒数
document.write(face.getFullYear() +"
");			//获取年
document.write(face.getMonth() +"
");			//获取月，从0开始算
document.write(face.getDate() +"
");				//获取日
document.write(face.getDay() +"
");				//获取星期，0表示星期日，6表示星期六
document.write(face.getHours() +"
");			//获取时
document.write(face.getMinutes() +"
");			//获取分
document.write(face.getSeconds() +"
");			//获取秒
document.write(face.getMilliseconds() +"
");		//获取毫秒
document.write(face.getTimezoneOffset() +"
");	//获取本地时间和UTC时间相差的分钟数
