怎样在html中显示时间,如何在网页上显示时间？

无标题文档

function show(){

var sweek=new Array("日","一","二","三","四","五","六");

var MyDate=new Date();

var mYear=MyDate.getFullYear();

var mMonth=MyDate.getMonth()+1;

var mDate=MyDate.getDate();

var mDay=sweek[MyDate.getDay()];

var mHours=MyDate.getHours();

var mMinutes=MyDate.getMinutes();

var mSeconds=MyDate.getSeconds();

document.write(mYear+"年"+mMouth+"月"+mDate+"日"+"星期"+mDay+""+mHours+":"+mMinutes+":"+mSeconds+"
");

}

show();

为什么我的显示不出来呀，长期坐等送分，请高手帮我改下
