Asp Syntax in ASP
Sure! Here’s a quick overview of the syntax basics in Classic ASP (VBScript) to get you started:
ASP Syntax Basics
Classic ASP primarily uses VBScript as its scripting language, embedded inside <% ... %>
blocks.
1. Script Block
<% ' Your VBScript code here%>
2. Output to Browser
<% Response.Write "Hello, World!"%>
or shorthand:
<%= "Hello, World!" %>
3. Comments
' This is a single-line comment
No multi-line comments in VBScript.
4. Variables
Dim namename = "Alice"
No explicit type declaration — variables are variants.
Use
Dim
to declare variables.
5. Data Types
String:
"text"
Integer/Double:
123
,3.14
Boolean:
True
/False
Date:
#2025-05-30#
Variant (default type)
6. Operators
Operator | Description |
---|---|
= | Assignment |
+ | Addition or concat* |
& | String concatenation |
- , * , / | Arithmetic |
And , Or | Logical operators |
= (in condition) | Equality test |
*Use &
preferably for string concatenation.
7. If...Then...Else
If x > 10 Then Response.Write "Greater than 10"ElseIf x = 10 Then Response.Write "Equals 10"Else Response.Write "Less than 10"End If
8. Loops
For loop
For i = 1 To 5 Response.Write i & "<br>"Next
While loop
While x < 10 Response.Write x x = x + 1Wend
Do While loop
Do While x < 10 Response.Write x x = x + 1Loop
9. Functions and Subroutines
Sub SayHello(name) Response.Write "Hello, " & nameEnd SubFunction Add(a, b) Add = a + bEnd FunctionSayHello("Bob")Response.Write Add(5, 3)
10. Including Files
<!--#include file="header.asp" -->
11. Accessing Form Data
Dim usernameusername = Request.Form("username")
