如何在Asp中象在JavaScrip里一样控制输入的值只能是英文或数字，现在我整理如下，下面我以接收变量String的值讲解如下：
2
3
方法一：
4
Str
=
Request(
"
String
"
)
5
Temp
=
Server.Urlencode(Str)
6
If
Str
=
Temp
Then
7
Response.Write
"
你输入的不是英文或数字"
8
End
If
9
10
文法二：
11
Str
=
Request(
"
String
"
)
12
For
I
=
1
To
Len
(Str)
13
A
=
Mid
(
String
,I,
1
)
14
If
((
Asc
(A)
<
"
0
"
And
Asc
(A)
>
"
9
"
)
Or
(
Asc
(A)
<
Asc
(
"
A
"
)
And
Asc
(A)
>
Asc
(
"
Z
"
)))
Then
15
Response.Write
"
你输入的不是英文或数字"
16
End
If
17
Next
