JavaScript学习与实践（6）

SWIYCH语句，是条件语句中的一种，具体写法给出一个例子，

用法：如果你必须在多个块中选择执行一个特定块，那么SWITCH语句是最好的，

<html>
2

<body>
3

var d = new Date()
5

theDay=d.getDay()
6

switch (theDay)
7

{
8

case 5:
9

document.write("Finally Friday")
10

break
11

case 6:
12

document.write("Super Saturday")
13

break
14

case 0:
15

document.write("Sleepy Sunday")
16

break
17

default:
18

document.write("I'm really looking forward to this weekend!")
19

}
20

</script>
21

This JavaScript will generate a different greeting based on what day it is. Note that Sunday=0, Monday=1, Tuesday=2, etc.
