帮助if语句。寻找jpg或gif [英] help with if statement. searching for jpg or gif
问题描述
原始代码：
<％img_name = rs（" ISBN"）& " .JPG"如果CheckPath（img_name）= true则％>
< IMG src =" ../ images / 70pixelsTall /<％= rs（" ISBN"）％> .jpg"宽度= QUOT; 50" height =" 70"
border = 0>
<％else％>
< img src =" .. /images/70pixelsTall/noimage70.jpg"宽度= QUOT; 50" height =" 70"
border = 0>
<％end if if％>
我想改变这样它也可以寻找GIF。如何在代码后添加
或更改原始代码，以便在jpg
无法检查/显示gif时显示。
<％img_name = rs（" ISBN"）& " .gif要点"如果CheckPath（img_name）= true则％>
< IMG src =" ../ images / 70pixelsTall /<％= rs（" ISBN"）％> .gif"宽度= QUOT; 50" height =" 70"
border = 0>
Original code:
<% img_name=rs("ISBN") & ".jpg" if CheckPath(img_name)=true then%>
<IMG src="../images/70pixelsTall/<%=rs("ISBN")%>.jpg" width="50" height="70"
border=0>
<% else %>
<img src="../images/70pixelsTall/noimage70.jpg" width="50" height="70"
border=0>
<%end if%>
I want to change this so that it also looks for gifs also. How can I add the
following code or change the original code so it checks/displays gifs if jpg
isn''t available.
<% img_name=rs("ISBN") & ".gif" if CheckPath(img_name)=true then%>
<IMG src="../images/70pixelsTall/<%=rs("ISBN")%>.gif" width="50" height="70"
border=0>

谢谢。但这实际上是我最初尝试的，不完全是。你
把& " .JPG"在第二个括号内，我把它保留原样。
但是，我确实尝试将代码复制并粘贴到我的上面，我得到了相同的
语法错误：
Microsoft VBScript编译错误''800a03ea''
语法错误
/search.asp，第909行
elseif
------ ^
Thanks. But that''s actually what I tried originally, well not exactly. You
put the & ".jpg" inside the 2nd parentheses and I left it out as it was.
However, I did try to copy and paste your code over mine and I got the same
syntax error:
Microsoft VBScript compilation error ''800a03ea''
Syntax error
/search.asp, line 909
elseif
------^

是的 - 谷歌推了一个在其他地方之后的行中断，那里不应该是b $ b。
ifif CheckPath（img_name&" .gif"）= true然后
应该都在一行。

Yeah - google shoved a line break after elseif where there shouldn''t be
one.
elseif CheckPath(img_name & ".gif")=true then
should all be on one line.
