I have a JavaScript issue?
I'm working the examples in my textbook (and I don't have the data files with the correct format) but I can't seem to get my output to show correctly.
The issue is that it's not concatenating the customer name and displaying the lower information after computing the cost.
// Welcome the user
// Ask for ordering information
document.write("Welcome to Bulk Is Best!" + BR);
firstName = prompt("Enter your name",ES);
lastName = prompt("Enter your last name",ES);
numPkgs = prompt("Enter number of packages",ES);
state = prompt("State to ship to",ES);
// Concatentate first and last name
custName = firstName + " " + lastName;
// Compute per package price and shipping cost
if (numPkgs >= 6) {
pkgPrice = "2.00";
}
else {
pkgPrice = "2.50";
}
if (state == "ID") {
shipCost = "0.00";
}
else {
shipCost = "4.00";
}
// Compute and document.write order totals
totPkgCost = pkgCost * numPkgs;
totOrderCost = totPkgCost + shipCost;
document.write("Order Summary for " + custName + BR);
document.write("Number packages ordered: " + numPkgs + BR);
document.write("Price per package: " + pkgPrice + BR);
document.write("Subtotal: " + totPkgCost + BR);
document.write("Order will be shipped to: " + state + BR);
document.write("Shipping cost: " + shipCost + BR);
document.write("Order total: " + totOrderCost + BR);
I couldn't fit the entire code in.
// Declare variables
var numPkgs;
var pkgPrice;
var totPkgCost;
var shipCost;
var totOrderCost;
var firstName;
var lastName;
var custName;
var state;
// Declare constants
var BR = "<br />";
var ES = "";

BR, ES, and pkgCost are undefined. I see them being used but they don’t have any values set in the code posted.
I get an unclosed string error from these two lines.
var BR = "
";
I assume that this isn't like this in your code, but the correct code is:
var BR = "";
pkgCost is still not defined. ^_^; I think you mean to write pkgPrice instead of pkgCost. The code breaks here so it never gets to writing the stuff to the screen due to the error.
