Sometimes when passing some parameters, in order to avoid Chinese and some special characters, I often use the contents of the server.urlencode function, and the encoded decoding encounters problems. Can use Unescape in JS, how to decode in ASP ?
I searched online and found the following method. After testing, I can decode Chinese correctly:
Function URLDECode (ENSTR)
DIM DESTR, STRSPECIAL
DIM C, I, V
DESTR = ""
STRSPECIAL = "!" "# $% & '() * ,.-_ / :; <=>? @ [/] ^` {|} ~% "
For i = 1 to len (ENSTR)
C = MID (ENSTR, I, 1)
IF c = "%" THEN
v = evAl ("& H" MID (ENSTR, I 1, 2))
IF INSTR (STRSPECIAL, CHR (V))> 0 THEN
DESTR = Destr & Chr (v)
i = i 2
Else
v = EVAL ("& H" MID (ENSTR, I 1, 2) MID (ENSTR, I 4, 2))
DESTR = Destr & Chr (v)
i = i 5
END IF
Else
IF c = " " THEN
DESTR = destr & ""
Else
DESTR = DESTR & C
END IF
END IF
NEXT
URLDECode = destr
END FUNCTION
