<%call ImgOutReplace(titdle,100,100)%>'子函数说明:内容,图片宽,图片高

这段代码有错吗?

为什么显示不出来图片

呃·我来回答下·别忘给分··

看了下函数·呃·有点眼花··用正则 会更简单些··

ImgOutReplace = CheckStr(ImgStr,3) CheckStr 这个函数不知道是干什么的·你没给·截取文件类型？？所以我把它删了··

ImgOutReplace = ImgStr

下面你出错的地方在这里了·

<%call ImgOutReplace(titdle,100,100)%>

呵呵··你这是 function 啊··

response.write ImgOutReplace ("<img src=ttt.jpg>",100,100)

呃··不知道你的 titdle 是什么·我用一个调用替换了·下·结果是可以提取到 ttt.jpg 的··

<img onload='javascript:DrawImage(this,100,100);' onmouseover='javascript:DrawImage(this,100,100);' src=ttt.jpg>

给分吧 ：）
