    Exclamation The Object Tag...

    Hello again ,

    I do not completely understand how the object tag in HTML works, for example here is a script that uses the object tag to bring up a color box -

    <html>
    <body>
    <object id="myDhelper"
    classid="clsid:3050f819-98b5-11cf-bb82-00aa00bdce0b">
    </object>
    <button onclick="myDhelper.chooseColorDlg();">Show color dialog</button>
    </body>
    </html>

    Some how without any code it brings up an color thing that would take hundreds of lines of code to do, how does this work ???...

    I think I once read that the classid has unique ids that have certain functions added to them (even if this is true please give ALL the details of that code abpve and possibly extra if there is anything extra)...

    Thanks

    The classid attribute is a URI (if the "magic GUIDs" IE uses can be called URIs) to a piece of code elsewhere. In this case, I'm guessing that GUID refers to an ActiveX control of some kind.

    Note that this (ab)use of the <object> tag will work only in IE, and that accessing elements by using their IDs as identifiers in the global namespace is very deprecated, and should never be used.

    Since it's IE-only (and Microsoft have never been lovers of documentation), documentation appears to be scarce.

    Yes, he is . Remember, it's IE only, and that's not user-friendly

    no, the object tag is supported in all browsers, otherwise you couldn't use java in FF...
    This preticular use is IE only.

    Come back once it validates: HTML, CSS, JS.
