?: (Conditional operator)
The conditional operator is the only _javascript_ operator that takes three
operands. This operator is frequently used as a shortcut for the if
statement.
Syntax
condition ? expr1 : expr2
Parameters
condition : an _expression_ that evaluates to true or false
expr1,expr2 : Expressions with values of any type.
Description
If condition is true, the operator returns the value of expr1; otherwise, it
returns the value of expr2. For example, to display a different message
based on the value of the isMember variable, you could use this statement:
document.write ("The fee is " + (isMember ? "$2.00" : "$10.00"))
