Newbie question: how to debug JS

DotNetter · Jul 18, 2005

I have the following code:

Code:

<html>
<head>

<title>Untitled</title>

<script>
function checkName(){
	//alert("Hi!")
	var UserName = document.myForm.UserName.value;
	if (UserName == "ME") {
		alert("Hello, YOU!!!");
	else
		alert("Hi, " + UserName + "!");
	}

	return (true);
}
//-->
</script>

</head>

<body>


<form name="myForm" onSubmit="return checkName()">

	<input type ="text" name="UserName">
	<input type ="submit" value="SUBMIT">
	<input type="reset">

</form>
</body>
</html>

I'm getting sytax errors on lines 11 and 25.

1) What's wrong with my syntax?
2) Are there any sites that let you plug in a script and they help you debug them?

Thanks!
Dot

Use FireFox - it has a built-in Javascript Console - which has more meaningful error messages.

You forget the braces fir the else statement.

<html>
<head>

<title>Untitled</title>

<script>
function checkName()
{
var UserName = document.myForm.UserName.value;
if (UserName == "ME")
{
alert("Hello, YOU!!!");
}
else
{
alert("Hi, " + UserName + "!");
}

return (true);
}
//-->
</script>

</head>

<body>

<form name="myForm" onSubmit="return checkName()">

<input type ="text" name="UserName">
<input type ="submit" value="SUBMIT">
<input type="reset">

</form>
</body>
</html>

I find that testing JS in older browsers is the easiest way to debug JS. I normally use NS 3.0, which I find is better than later NS. Unable to use FF, and IE sucks big time.
