為什么不能加default？
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>switch</title>
<script type="text/JavaScript">
var myweek =3;//myweek表示星期幾變量
switch (myweek)
{
?case 1:
?case 2:
?document.write("學習理念知識");
?break;
?case 3:
?case 4:
?document.write("到企業實踐");
?break;
?case 5:
?document.write("總結經驗");
?break;
?case 6:
?case 7:
?document.write("周六、日休息和娛樂");
break;
?default：
?document.write("666"); //加了之后好像就不能運行了
}
</script>
</head>
