    Hi all,
    Although I am a developer - I never coded in javascript.

    Now, here I am trying to order a laptop from the Dell online shop but
    everytime I try to press 'continue' after picking the options, I get
    an error message in the lower left hand corner of the browser.
    I'm using WIN 98SE with java enabled on my laptop.

    The error log says:
    Line: 1
    Char: 1
    error: object expected
    code: 0

    And this is the line which pops up when I place the cursor on the
    'continue' button causing the above error:

    javascript:next_page('1','c=us&cs=19&kc=6V602&l=en&oc=5100FS&s=dhs');

    I would assume there's a bug in that line. Although there's little I
    can do about it other than forward it to the Dell folks - my pgming
    background has me curious as to what's causing this!
    Perhaps I have some settings set wrong on my laptop.

    Thanks ....

    Aren't 'puters fun?;-))

    That error message usually relates to event handling code. Mozilla and
    Opera both generate better (more informative (usually)) error messages
    than IE (in their JavaScript consoles).

    It is a pity that you have omitted the HTML context so that we cannot
    tell whether this is an HREF abuse or an onclick handler. It is probably
    the latter, in which the "javascript:" prefix is usually
    unnecessary/meaningless (but also harmless).

    The only object that is referred to is the - next_page -function, so
    that identifier cannot be resolved. That should not happen and certainly
    should have shown up in QA testing.

    Interestingly, this code represents Dell making their online purchasing
    needlessly dependent on JavaScript, I wonder how much this decision is
    costing them in lost business even without the code being erroneous.

    It is unfortunately the case that there is a (mistaken) attitude that
    any fool can write JavaScript, which manifests itself in fools often
    being given the task of writing JavaScript. This fool is costing Dell
    more than they are loosing due to their decision to make purchases
    needlessly dependent on JavaScript(assuming it actually was a decision
    rather than just another consequence of assigning the task to someone
    who knew no better).

    The failure to resolve the identifier as a reference to a function
    implies that the error is elsewhere, but if the function code is missing
    then there is not much that can be doe about it. If the function
    reference is being overwritten, or the function definition is in some
    way incorrect then there may be some remedial action that you could take
    (at least if you knew JavaScript/HTML well enough).

    Perhaps I have some settings set wrong on my laptop.

    No, you have done nothing wrong. The fault is entirely with Dell, and
    you should maybe ask yourself whether it is a good idea to be doing
    computer related business with a company that cannot even implement a
    web purchasing system properly, there is no shortage of competition in
    the computer retailing world.

    What browsers display the onclick handler upon mouseover? 99.99% of the
    time, if it shows that in the status bar (or a tooltip), it is generally
    a sign of this:

    <a href="javascript:.......">

    Good point! Its HREF abuse, though the error report sounded more like an
    event handler. Though I don't see error reports from javascript: pseudo
    protocol code often because I never use them ;-)

    Richard,
    That's because it's a large piece of code ;-))
    (won't fit in the notebook!)
    Here's the line that contains the probllem line:

    ....<a name="bottom_anchor"></a></td><td width=10>&nbsp;</td>
    <td width=125><a
    href="javascript:next_page('1','c=us&cs=19&kc=6V603&l=en&oc=5150FS&s=dhs');"
    class="lnk"><img
    src="http://img.dell.com/img.aspx?p=cnvEY3QAxpmMra5pPAKeMiksUgDeqQR3YLPndy9bnjR9ajxW1LVMblr%2frCZ7VpcpNHVNYdSpXUtd5KImew3M"

    URL? It could be that the JS isn't loading properly and the next_page()
    functions doesn't exist.

    I don't know why you're replying to me, but there is no previous line -
    this code is in the href of a link.
