简单的换行问题！

Question

保存到库里面是保存了chr(10)进去，显示的时候把它替换成<br>就ok了。

Answer 1

输出的时候进行转换
asp: 
     Server.HTMLEncode(str);
     Replace(str,chr(13),"<br>");
     Replace(str,chr(32),"&nbsp;");php: nl2br(htmlspecialchars($str));

Answer 2

用函数格式化.
在写入数据时.<%
function htmlencode2(str)
    dim result
    dim l
    if isNULL(str) then 
       htmlencode2=""
       exit function
    end if
    l=len(str)
    result=""
dim i
for i = 1 to l
    select case mid(str,i,1)
           case "<"
                result=result+"&lt;"
           case ">"
                result=result+"&gt;"
              case chr(13)
                result=result+"<br>"
           case chr(34)
                result=result+"&quot;"
           case "&"
                result=result+"&amp;"
              case chr(32)            
                'result=result+"&nbsp;"
                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+"&nbsp;"
                   else
                      result=result+" "
                   end if
                else
                   result=result+"&nbsp;"                     
                end if
           case chr(9)
                result=result+"    "
           case else
                result=result+mid(str,i,1)
         end select
       next 
       htmlencode2=result
   end function
%><%
rs("content") = htmlencode2(Request.Form("content"))
%>
