有没有人知道如何将<和>改成<>

谢谢了

[a95470000]

不太明白意思,再说清楚点

[Atai-Lu]

直接用
replace(字符串,"<",">")
replace(字符串,">","<")

[rentj1]

用替换好了replace("字符串内容","<",">")
replace(字符串内容，">","<")

字符串是什么，如果我表中的字段是content，那么这个字段是否就是content.

[rentj1]

replace(rs("content"),"<",">")
replace(rs("content"),">"," <")

[Atai-Lu]

rentj1老兄，不好意思，csdn的聊天工具我这里打开太慢了，网速不好，每次打开浏览器都要进入假死状态，所以没法直接回复你的信息了...

[fwy12]

function changechr(str)
changechr=replace(replace(replace(replace(str,"<","<"),">",">"),chr(13),"<br>")," "," ")
changechr=replace(replace(replace(replace(changechr,"[sayyes]","<img src="),"","<b>"),"[red]","<font color=CC0000>"),"[big]","<font size=7>")
changechr=replace(replace(replace(replace(changechr,"[/sayyes]","></img>"),"","</b>"),"[/red]","</font>"),"[/big]","</font>")
end function



这段代码是什么意思呢

[Atai-Lu]

字符替换...
这么难看的代码，无语...

[fwy12]

我想解决的问题是，我用eWebEditor输入数据库的是"<",类型的代码，怎样让输出的内容正常显示呢，

[rentj1]

输出正常就麻烦了 别人就可以注入了

[fwy12]

输出的是html代码，那也没什么意义，我想让html代码改为正常的显示，如图片，应该在网页显示图片而不是<img...
的代码。请问该怎么办啊。

你用代码视图来写

这样应该明白吧,我想应该是无法把一些特殊符号和html标签存入数据库,
在存的时候先进行过转换,从数据库抓出来的时候又将特殊的符号转换回来

[fwy12]

如何从数据库中抓取的时候转换回来呢

考验我的耐心啊．．．．．．

该下上面的：
