Javascript- Multiplying 2 numbers and return number

javascriptfunctionparameters

提问by terry

I normally have understood this stuff well as I am taking web programming for a non-major class and guess I am just a little confused on what I'm being asked to do.

我通常已经很好地理解了这些东西,因为我正在为非专业课程学习网络编程,我想我只是对我被要求做的事情有点困惑。

I am told to "Write a function named "MULTIPLY" that accepts 2 parameters. the function will be declared this way:

我被告知“编写一个名为“MULTIPLY”的函数,它接受 2 个参数。该函数将以这种方式声明:

function MULTIPLY(parameter1, parameter2){
    //The parameter names can be whatever you want 
    //Your code goes here

};

I have wrote this as my code :

我写了这个作为我的代码:

function MULTIPLY (price, shipping) {
    return price*shipping;

    enter code here

    product=number1*number2;

    //return the result

    return total;

<script>
    function multiplyNumbers(x,y){
        return x*y;
    }
    var z= multiplyNumbers(4,5); // Function is called, return value will end up in z

</script>
<button onclick="document.getElementById('multiplication').innerHTML=z;">Multiply numbers</button>
<p id="multiplication"></p>

You have a few problems. Here is how it should look

你有几个问题。这是它的外观

function MULTIPLY(price, shipping) {
    //Return the sum
    return price*shipping;
}

//Call MULTIPLY to multiply the two numbers
var product=MULTIPLY(number1, number2);
