One must start from somewhere....

Hi, I'm learning JS, and I need help. Here is my code:

//This object is going to be used
//so that at the end of the calcCost function,
//the client can see the subtotal, tax, and grandtotal
//in a portion of the webpage. Like a console, mayhaps.
var dataWindow=new Object();
dataWindow.height=80;
dataWindow.width=500;
//This is the function that takes the subtotal, tax and grandtotal and simply displays them in 
//the data window.
dataWindow.showResults=function(subtotal,tax,grandtotal){
	return "Subtotal" + subtotal;
	return "Tax" + tax;
	return "Grandtotal" + grandtotal;
}
//This is the function that calculates the subtotal, tax and grandtotal.
function calcCost(){
var itemCost=prompt("Enter the cost of the item here.");
	var subtotal=itemCost;
		document.write("Subtotal" + subtotal);
	var tax=.0825;
		document.write("Tax Charge" + tax);
	var grandtotal=(subtotal*tax);
		document.write("Grand Total" + grandtotal);
	dataWindow.showResults();//this call of the function should take the   subtotal,tax and grandtotal
	//and display them in the dataWindow.
}

I truly appreciate the help, and realize this is probably the stupidest code you've all laid eyes on. I apologize, but one must start from SOMEWHERE.

function calcCost() {
var cost = prompt("Enter the cost of the item here.");
var tax = 0.0825;
alert("Subtotal: "+cost+"\nTax Charge: "+(cost*tax)+"\nGrand Total: "+((1+tax)*cost)); }

Is that what you were looking for?

the

function calcCost

isn't what I had the problem with, its the

dataWindow

object. I made the object because i wanted to be able to have it dynamically update with the subtotal,grandtotal and tax parameters.

You may want to look into the uses of "window.showModalDialog"
