Operands
expression1 : Object - An expression that evaluates to a Boolean value; usually a
comparison expression, such as
x < 5.
expression2 : Object - Values of any type.
expression3 : Object - Values of any type.
Returns
Object - The value of expression2 or expression3.
Example
The following statement assigns the value of variable
x to variable z because expression1
evaluates to
true:
var x:Number = 5;
var y:Number = 10;
var z = (x < 6) ? x: y;
trace (z); // returns 5
The following example shows a conditional statement written in shorthand:
var timecode:String = (new Date().getHours() < 11) ? "AM" : "PM";
trace(timecode);
The same conditional statement could also be written in longhand, as shown in the following
example:
if (new Date().getHours() < 11) {
var timecode:String = "AM";
} else {
var timecode:String = "PM";
} trace(timecode);
