ASP
Programming - VBScript
As was mentioned in the last
lesson, ASP uses VBScript as its
default scripting language.
VBScript is similar to Javascript,
a client side programming language
used to add functionality through
the <script> tag.
Read the following paragraph
carefully!
VBScript, when used to program
ASP converts it to server side
scripting. Any given web page
could be created from a
combination of server side and
client side scripting. The
confusing part is this: You must
use these client side scripting
languages (Javascript, VBScript,
etc) to program in ASP!
Below we have a simple ASP
script programmed in VBScript and
includes the necessary HTML as
well. This is only server-side
scripting.
Server Side ASP Code using
VBScript:
<html>
<body>
<%
Dim myString
myString = Date()
Response.Write("The date is: "
& myString)
%>
</body>
</html> |
Display:
If you already know VBScript or
Visual Basic programming then
you'll recognize Dim as Dimension,
which is used to "dimension"
variables. It is a good
programming practice to
"dimension" all your variables
before you use them, as we did
with myString in the above
example.
Now that we have our ASP Code
working, say that we wanted to use
our ASP code along with some
client side Javascript code. To
keep it simple we are just going
to use the Javascript write
function and have our ASP Code
fill in the Date. All the
Javascript client code is in the
default color, but ASP Server Side
Code is in Red.
ASP Code w/ VBScript and
Client Side Javascript Code:
<script>
document.write("The date is:<%
Dim myString
myString = Date()
Response.Write(myString)
%>")
</script> |
Display:
If you just want to program in
ASP you can disregard the above
example if you find it confusing.
Just remember that you can have
client-side Javascript code and
server-side ASP/VBScript code
included in an ASP generated web
page!
