为什么我输入数字之后没有出现与数字对应的话？
<!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表示星期几变量break;
function m(){
var myweek;
myweek=prompt("今天星期几？")
switch(myweek)
{
case 1:
case 2:
document.write("学习理念知识");
break;
case 3:
case 4:
document.write("到企业实践");
break;
case 5:
document.write("总结经验");
break;
case 6:
case 7:
document.write("周六、日休息和娱乐");
default:
document.write("出错了哦~");
}
}
</script>
</head>
<body>
<input type="button" value="戳我啊~~" onclick="m()" />
</body>
</html>
