Hey Proboarders, I''m currently taking a Computing class and we were just introduced to a few things in JavaScript such as alerts and prompts.
However I'm having a problem; the +yourname is displaying as NaNa
<html>
<head>
<title>
Homework 7
</title>
</head>
<body>
<script type="text/javascript" language="javascript">
<!--
yourname = prompt("What is your favorite sport?" );
document.write( + yourname + " is my favorite sport too");
// -->
</script>
</body>
</html>
</html>
Another thing, i'm trying to get +yourname in italics. I've tried using the <i> </i> tags but it isn't working:
<html>
<head>
<title>
Homework 7
</title>
</head>
<body>
<h2>
<script type="text/javascript" >
yourname = prompt("What day is it today?" );
document.write("Today is " <i> + yourname + </i> " Have a nice day!");
</script>
</h2>
</body>
</html>

The prompt function takes two parameters with the second being the default value. It's normally left blank like this.
var yourname = prompt("What day is it today", "");
Also, you don't need the concatenation operator before the variable on this line.
document.write( + yourname + " is my favorite sport too");
And the <i>'s are strings, so they need to be in quotes like this.
document.write("Today is <i>" + yourname + "</i> Have a nice day!");

Hey Jordan, I understood everything except the first part:
What exactly is left blank? We didn't go over terms that heavily, so I may be confused at that part.

You forgot your default value, I believe. If you just had var yourname = prompt("What day is it today?", ""); If you add something to the second set of quotations, it will show up in the prompt before you enter anything  |
