Parameters
expression
A string, number, array, or object to evaluate and return as a value of the function. This parameter is optional.
Returns
The evaluated expression
parameter, if provided.
Description
Action; specifies the value returned by a function. The return
action evaluates expression
and returns the result as a value of the function in which it executes. The return
action causes the function to stop running and replaces the function with the returned value. If the return
statement is used alone, it returns null.
Example
The following example uses the return
action inside the body of the sum
function to return the added value of the three parameters. The next line of code calls the sum
function and assigns the returned value to the variable newValue
:
function sum(a, b, c){
return a + b + c;
}
newValue = sum(4, 32, 78); trace(newValue); // sends 114 to the Output window
