    Absolute beginner

    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.

      Resulting source code vs rendered HTML

      Dave.

      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.

        Re: Absolute beginner

        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?
