Hi all.

Have literally just begin to look at JavaScript and am just past the "Hello World" stage and have encountered a problem.

I have the code:

<html>
<head>Test</head>
<body>
<script language="JavaScript">
document.write("No line after this")
document.writeln("A line after this")
document.write("No line after this")
</script>
</body>
</html>

When I browse the html file I get the output:

No line after thisA line after thisNo line after this

without the line break I expected from the .writeln method.

Can someone please tell me what I'm doing wrong here.

Thanks in advance.

Russell.

<html>
<head></head>

Test
<script language="JavaScript">
document.write("No line after this")
document.write("A line after this<br>")
document.write("No line after this")
</script>
</body>
</html>

Thanks for your email.

I'm not sure if I do understand the distinction.

More explicitly, I guess, I don't understand what the "resulting source code" in fact is.

My html file reads the same to me whether I look at it using Notepad or browse it as an HTML document using IE.

Under what conditions would I want to use document.writeln() if <br> is required to give me a new line on a browsed page?

Thanks again.

Russell.

The resulting source code for this:

<html>
<head>Test</head>
<body>
<script language="JavaScript">
document.write("No line after this")
document.writeln("A line after this")
document.write("No line after this")
</script>
</body>
</html>

is:

<html>
<head>Test</head>
<body>
No line after thisA line after this
No line after this
</script>
</body>
</html>

The rendered HTML is:

No line after thisA line after thisNo line after this


While the resulting code for this:

<html>
<head></head>
<body>
Test
<script language="JavaScript">
document.write("No line after this")
document.write("A line after this<br>")
document.write("No line after this")
</script>
</body>
</html>

is:

<html>
<head></head>
<body>
Test
No line after thisA line after this<br>No line after this
</script>
</body>
</html>

The rendered HTML is:

No line after thisA line after this
No line after this


The resulting source code is the HTML source generated. Code generated by document.write's are not shown when you click View-Source in the browser, but internally it generated the output discussed above.
Rendered HTML is the generated output when the browser interprets the resulting source code.

Hope I discussed it clearly. :)

Do you see the distinction now?

I understand the distinction now. Thanks for your very clear explanation.
