    JavaScript and CSS Classes

    Can you change with code the CSS class of an object after the web page has been downloaded? Does anybody know how?!

    Thank you!

    You can in DOM 3. I'm not sure about the current standards.

    As always, RTFM.

    WWW Standards: HTML 4.01, CSS Level 2, ECMA 262 Bindings to DOM Level 1, JavaScript 1.3 Guide and Reference
    Perl: Learn Perl, Llama, Camel, Cookbook, Perl Monks, Perl Mongers, O'Reilly's Perl.com, ActiveState, CPAN, TPJ, and use Perl;
    YBMS, but Mozilla doesn't.

    Its the Document Object Modal, a way of addressing an element/Tag on a HTML Page.

    If you had this code...

    <body>
    <input type="text" name="text1">
    </body>

    ... you can use the DOM and a scripting language such as Javascript to get the value in the text...

    alert (document.all("text1").value);

    ...This would display a popup msg with the contents or text1.

    document indicates the page your working on
    all("text1") searching all elements on a page until it finds a item named 'text1'. all is only really used in Internet Explorer 4 +, I prefer getElementById but only modern browsers support it
    value returns/sets the value of item

    Set the "className" attribute of an HTML element.

    Get these: Mozilla Opera OpenBSD
    I have books for sale: "MCSD in a Nutshell" and "VB Distributed Exam Cram" - PM me for details. Will also trade for a decent ATX Pentium 2 MB/CPU/RAM combo.
