Three types of conditional statements are there in VBScript.
if...then...else statement
Example of if without else:
1)
if i=2 Then msgbox "Hello World"
2)
3)
More than one statement can be executed for truth condition by putting the statements on separate line.
if i=2 Then
msgbox "Hello World"
i = i+1
end If
Example of if...then...else
1)
if i=2 then
msgbox "Hello World"
else
msgbox "Thank You"
end If
2)
if...then...elseif statement
1)
if fee="Cash" then
msgbox "pay cash!"
elseif fee="Visa" then
msgbox "pay with visa."
elseif fee="American Express" then
msgbox "pay with American Express."
else
msgbox "Unknown method of Payment."
end If
2)
select case statement
1)
select case fee
case "Cash"
msgbox "pay cash"
case "Visa"
msgbox "pay with visa"
case "American Express"
msgbox "pay with American Express"
case Else
msgbox "Unknown method of fee"
end select
2)
3)
A single expression (usually variable) is evaluated once and its value is then compared with the values for each case. If there is a match, the block of code associated with that case is executed. If there is no match then Else case is executed.
