Question

我通常已经理解了这些东西，因为我正在为一个非主要课程进行网络编程，并且猜测我对我被要求做的事情感到有些困惑。

我被告知＆＃34;写一个名为＆＃34; MULTIPLY＆＃34;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

};

我把它写成我的代码：

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

    enter code here

    product=number1*number2;

    //return the result

    return total;

Answer 1

<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>

Answer 2

你有一些问题。这是它应该看起来的样子

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

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

Answer 3

function multiply(a, b) {
    let first = parseInt(prompt("Enter 1st Value"));
    let second = parseInt(prompt("Enter 2nd Value"));
    return first * second;
}
multiply();

Javascript-乘以2个数字并返回数字
