ProblemYou want to perform some method and return the results to the statement that invoked the function. SolutionUse a return statement that specifies the value to return. DiscussionWhen used without any parameters, the return statement simply terminates a method. However, any value specified after the return keyword is returned to statement that invoked the method. Usually, the returned value is stored in a variable for later use. The datatype of the return value must match the return type of the method: private function average (a:Number, b:Number):Number { return (a + b)/2; } Now we can call the average( ) method and store the result in a variable and use the result in some way. var playerScore:Number = average(6, 10); trace("The player's average score is " + playerScore); You can use the return value of a method, without storing it in a variable, by passing it as a parameter to another function, such as: trace("The player's average score is " + average(6, 10)); Note, however, that if you do nothing with the return value of the function, the result is effectively lost. For example, this statement has no detectable benefit because the result is never displayed or used in any way: average(6, 10); |
