Function problems in ASP

[Frank]

I'm running the current function:

isbn="08307.25318"

function geturl(value)
image="http://www.gospellight.com/Merchant2/graphics/00000001/"
image=image & value & ".jpg"
response.write image
end function

geturl(isbn)

If I run this in an html page, it works fine, as in <% geturl(isbn) %>
and that is inserted into the html, it works.

However, if this is inserted into a line of asp code, it blows up on
me, prorobly because of the response.write inside of the function. If
I take out the response.write, it dosn't return any value at all. How
do I get it to return a value if I'm not using the response.write
object/method?

[Chris Barber]

function geturl(value)
image="http://www.gospellight.com/Merchant2/graphics/00000001/"
image=image & value & ".jpg"
geturl = image
end function

Or a slightly better coded version (with variable type suggestions):

'Function to return a modified image URL from the image name part and a
standard base path and extension.
Function GetURL(pstrValue)
Dim pstrImageURL
'Set the base path for the images.
pstrImageURL="http://www.gospellight.com/Merchant2/graphics/00000001/"
'Add the specific image name and extension.
pstrImageURL = pstrImageURL & pstrValue & ".jpg"
'Return the newly concatenated value.
GetURL = pstrImageURL
End Function

I suspect that you don't have 'Option Explicit' at the top of your ASP page
and are relying on implicit variable creation? That's pretty dangerous - you
should always have Option Explicit set and declare your variables to aid in
debugging.

<%
isbn="08307.25318"

function geturl(value)
image="http://www.gospellight.com/Merchant2/graphics/00000001/"
image=image & value & ".jpg"
geturl = image
end function
%>

And then do:

<img src="<% = geturl(isbn) %>">
Or

Response.write "<img src='" & geturl(isbn) & "'>"
