7. You Deserved it - what is wrong


#1


function StaffMember(name,discountPercent){
this.name = name;
this.discountPercent = discountPercent;
}

var sally = new StaffMember("Sally",5);
var bob = new StaffMember("Bob",10);

// Create yourself again as 'me' with a staff discount of 20%
var me = new StaffMember("Me",20);

var cashRegister = {
total:0,
lastTransactionAmount: 0,
add: function(itemCost){
this.total += (itemCost || 0);
this.lastTransactionAmount = itemCost;
},
scan: function(item,quantity){
switch (item){
case "eggs": this.add(0.98 * quantity); break;
case "milk": this.add(1.23 * quantity); break;
case "magazine": this.add(4.99 * quantity); break;
case "chocolate": this.add(0.45 * quantity); break;
}
return true;
},
voidLastTransaction : function(){
this.total -= this.lastTransactionAmount;
this.lastTransactionAmount = 0;
},
// Create a new method applyStaffDiscount here
applyStaffDiscount: function (employee) {
this.total-=this.total *(employee.discountPrecent / 100);
},

};

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',3);
// Apply your staff discount by passing the 'me' object
// to applyStaffDiscount
cashRegister.applyStaffDiscount('me');

// Show the total bill
console.log('Your bill is '+cashRegister.total.toFixed(2));

I got: Oops, try again. false


Replace this line with your code.


#2

here:

cashRegister.applyStaffDiscount('me');

why is 'me' a string?

you also have a variable me:

var me = new StaffMember("Me",20);

which would make more sense to to give discount, since that is instance of staffmember


#3

thx. I changed 'me' to me and it works


#4

do you also understand why this change is so crucial?
