VBScript program
VBScript can use two procedures:
- Subroutine
- Functional Programming
VBScript subroutine
Subroutine:
- It is a series of statements, Sub and End Sub statements are encapsulated within
- Perform some operations, butdoes not return value
- You can have parameters
Sub mysub()
some statements
End Sub
or
Sub mysub(argument1,argument2)
some statements
End Sub
Examples (only for IE)
Sub mysub()
document.write("I was written by a sub procedure")
End Sub
VBScript function program
Functional Programming
- Is a series of statements, are encapsulated within the Function and End Function statements
- Perform certain operations, andreturns a value
- Parameter called to pass it through the program may have.
- If there is no argument, it must have empty parentheses ()
- Through the program name assigned to the function of the way, so that it can return a value
Function myfunction()
some statements
myfunction=some value
End Function
or
Function myfunction(argument1,argument2)
some statements
myfunction=some value
End Function
Examples (only for IE)
function myfunction()
myfunction=Date()
end function
Calling program
This simple function is invoked to calculate two arguments:
Examples (only for IE)
Function myfunction(a,b)
myfunction=a+b
End Function
document.write(myfunction(5,9))
Function "myfunction" returns the parameters "a" and the parameter "b" and. Here returns 14.
When you call the program, you can use the Call statement, as follows:
Alternatively, you can omit the Call statement as follows:
