我正在尝试创建一个代码,该代码将询问用户有多少 X、Y 等项目,并使用 Javascript 计算欠款总额,并打印所有购买项目的摘要(收据)。抱歉,新手问题,试图在没有任何正式培训的情况下学习代码。感谢所有的帮助!

function packageTotal(){
//Enter in prices here
var applePrice = 1;
var bookPrice = 2;
x = Number(document.calculator.books.value);
y = Number(document.calculator.apples.value);
var b = applePrice*x + bookPrice*y;
var p = applePrice*x + bookPrice*y + .5;

//Basic package is checked
