需要把 回车换行 替换成 <br>等
ASP的例子:
<%
'字符串HTML编码
function htmlencode(str)
dim result
dim l
if isNULL(str) then
htmlencode=""
exit function
end if
l=len(str)
result=""
dim i
for i = 1 to l
select case mid(str,i,1)
case "<"
result=result+"<"
case ">"
result=result+">"
case chr(13)
result=result+"<br>"
case chr(34)
result=result+"""
case "&"
result=result+"&"
case chr(32)
'result=result+" "
if i+1<=l and i-1>0 then
if mid(str,i+1,1)=chr(32) or mid(str,i+1,1)=chr(9) or mid(str,i-1,1)=chr(32) or mid(str,i-1,1)=chr(9) then
result=result+" "
else
result=result+" "
end if
else
result=result+" "
end if
case chr(9)
result=result+" "
case else
result=result+mid(str,i,1)
end select
next
htmlencode=result
end function
'HTML编码还原
function htmldecode(str)
str=trim(str)
if isNull(str) then
htmldecode=""
exit function
end if
str=replace(str,"<","<")
str=replace(str,">",">")
str=replace(str,"<br>",chr(13))
str=replace(str,""",chr(34))
str=replace(str,"&","&")
str=replace(str," ",chr(32))
htmldecode=str
end function
%>

更简单的办法是
在显示时 直接给个 文本域Top
