Answer: Return an Array of Values
A function cannot return multiple values. However, you can get the similar results by returning an array containing multiple values. Let's take a look at the following example:
Example
Try this code »<script>
// Defining function
function divideNumbers(dividend, divisor){
var quotient = dividend / divisor;
var arr = [dividend, divisor, quotient];
return arr;
}
// Store returned value in a variable
var all = divideNumbers(10, 2);
// Displaying individual values
alert(all[0]); // 0utputs: 10
alert(all[1]); // 0utputs: 2
alert(all[2]); // 0utputs: 5
</script>Alternatively, you can also return an object if you want to label each of the returned values for easier access and maintenance, as demonstrated in the following example:
Example
Try this code »<script>
// Defining function
function divideNumbers(dividend, divisor){
var quotient = dividend / divisor;
var obj = {
dividend: dividend,
divisor: divisor,
quotient: quotient
};
return obj;
}
// Store returned value in a variable
var all = divideNumbers(10, 2);
// Displaying individual values
alert(all.dividend); // 0utputs: 10
alert(all.divisor); // 0utputs: 2
alert(all.quotient); // 0utputs: 5
