请问我这段代码哪里错了呀 ？为何无法显示结果

  var mydate=new Date();
  var year=mydate.getFullYear();
  var month=mydate.getMonth()+1;
  var date=mydate.getDate();
  var day=myweek[mydate.getDay()]
  var myweek=["星期日","星期一","星期二","星期三","星期四","星期五","星期六"]
  document.write(year+"年"+month+"月"+date+"日"+day);

    myweek这个数组应该是放在day之前合理些，还有，每句代码之后加上”；”

    为什么myweek要放在day之前的原因是因为代码是依次执行的，先执行“var day=myweek[mydate.getDay()]；”这句，这时候myweek的初始化还没有做，所以day拿不到myweek的值
