Prompted name document.writes as NaN

Kamma1124 · 02-26-2013, 03:18 AM

Hello everyone, very sorry upfront for the poor code. I need the script to spit out the person name not NaN. Basically what is happening is the script asks for a number and your name. The program is supposed to spit out your commission rate and your name. The script will spit out the commission rate just fine but the name shows up as NaN. please explain what I am doing wrong so that I may learn. Thank you.

Code:

<html>
<head>
<title>Patrick  - assignment03 - Exercise 2<</title>
</head>
<body bgcolor="DeepSkyBlue" text="wheat">
<script language="JavaScript" type="text/javascript">
alert("Welcome to Commission Calculator")	
	var num1 = prompt("Please enter your Total Sales Amount: ", "" );
	var name= prompt("Please enter your Name: ", "" );
document.write("===== Sales Commission Script ======", "<br>")
document.write("====== by Patrick  ===========", "<br>")
	if (num1 <= 9999)
document.write( +name+ " Your commission is " , (num1) * .02, "<br>")
	else if (num1 >= 10000)
document.write( +name+ " Your commission is $" , (num1) * .05 + 200, "<br>")
</script>
</body>
</html>

I guess I figured it out because I got my script to work. If anyone does look at this post at all. Can someone please chime in and let me know if they know of any good sources to read that could make things like this easier for me. It would be very greatly appreciated.

Code:

<html>
<head>
<title>Patrick - assignment03 - Exercise 2<</title>
</head>
<body bgcolor="DeepSkyBlue" text="wheat">
<script language="JavaScript" type="text/javascript">
alert("Welcome to Commission Caculator")	
	var num1 = prompt("Please enter your Total Sales Amount: ", "" );
	var name = prompt("Please enter your Name: ", "" );
	
document.write("===== Sales Commission Script ======", "<br>")
document.write("====== by Patrick ===========", "<br>")
	if (num1 <= 9999) 
	{
document.write( name, " Your commission is " , (num1) * .02, "<br>")
	}
	else if (num1 >= 10000)
	{
document.write( name, " Your commission is $" , (num1) * .05 + 200, "<br>")
	}
</script>
</body>
</html>

The first thing you need to do is to forget almost everything you have in your code.

document.write is completely obsolete and should no longer be used.

prompt and alert should only be used for debugging and should be removed before you upload a scrip to the web.

I have a few hundred example scripts on javascriptexample.net that start with some for beginners to learn the basics.
