Is there an operator for appending to a string variable in ASP?

Question

what's the asp equivalent to php's .= when concatenating strings?? oh and i'm referring to asp NOT asp.net.

argh...i meant to specify that i'm in a for loop. so i want to know the equivalent for .= (in php) not standard concatenation.

example below:

For Each Item In Request.Form
    If (Item = "service") then 
        For x=1 To Request.Form(item).Count
            service = "&service="&Request.Form(Item)(x)
        Next
    End If
Next

Answer 1

In VBScript:

Variable = Variable & "something more"

In JScript I believe you can use:

variable += "something more";

Specifically:

service = service & "&service=" & Request.Form(Item)(x)

assuming you want your result to look something like...

&service=blah1&service=blah2&service=blah3

Though you may need to URL encode your Request.Form(Item)(x) values because any "&" (and other characters) could really muck up what you are trying to do. Also be careful when using unsanitized input like this directly from an HTML form, its very dangerous.

I can't remember for certain, but &= should work in ASP. I know it works in VB.Net. Although I can't recall if that worked in asp. If that doesn't work, the only solution is a = a & b.

It looks like you have found your answer, but here is a good reference that relates to your question: http://www.design215.com/toolbox/asp.php
