Question

ASP中 replace函数替换问题，请大家帮忙啊

Replace(rs("IF_content"),"><img"," rel="nofollow"><img")

本意是用这个字符串 rel="nofollow"><img 替换掉： ><img 但是不执行，提示出错，如图所示

我写的完整程序代码如下所示：
<%
Dim rs,sql,text
Set rs=Server.CreateObject("ADODB.Recordset")
sql="Select IF_content From OT_info"
rs.Open sql,conn,1,3
Do While Not rs.Eof
text=Replace(rs("IF_content"),"><img"," rel="nofollow"><img")
rs("IF_content")=text
rs.Update
rs.MoveNext
Loop
rs.Close
Set rs=Nothing
%>

请高手解答一下啊

Answer 1

text=Replace(rs("IF_content"),"><img"," rel="nofollow"><img")
这句要用到转义，改成
text=Replace(rs("IF_content"),"><img"," rel=\"nofollow\"><img")

Answer 2

把rel="nofollow" 换成rel=\"nofollow\",这个跟你参数外层的“”冲突了

Answer 3

text=Replace(rs("IF_content"),"><img"," rel=""nofollow""><img")
字符串中的双引号要用两个连在一起的双引号转义

Answer 4

用上双引号""nofollow""
