ASP Subroutines
In ASP, you can call JavaScript subroutines from VBScript, and vice versa.
Subroutines
ASP source code can contain subroutines and functions:
Examples
<html>
<head>
<%
sub vbproc(num1,num2)
response.write(num1*num2)
end sub
%>
</head>
<body>
<p>Result: <%call vbproc(3,4)%></p>
</body>
</html>
Demo Examples »
Put the <%@ language=language" %> line above the <html> tag, and you can use another scripting language to write subroutines or functions:
Examples
<!DOCTYPE html>
<html>
<head>
<%
function jsproc(num1,num2)
{
Response.Write(num1*num2)
}
%>
</head>
<body>
<p>Result: <%jsproc(3,4)%></p>
</body>
</html>

Differences Between VBScript and JavaScript
When calling a VBScript or JavaScript subroutine from an ASP file written in VBScript, you can use the "call" keyword, followed by the subroutine name. If the subroutine requires parameters, the parameters must be enclosed in parentheses when using the "call" keyword. If you omit the "call" keyword, the parameters do not need to be enclosed in parentheses. If the subroutine has no parameters, the parentheses are optional.
When calling a VBScript or JavaScript subroutine from an ASP file written in JavaScript, you must use parentheses after the subroutine name.
