Perl webpage with some JS, need help please!

[markus414]

Hello,

I have invested in a numberplate making system which uses perl scripts to allow the user to design and order numberplates. I have no access to the server or to the scripts which run it, as it is a turnkey system.

I am trying to allow the user to only design the plate (stage 1 or 5 in the maker), after which I want to interrupt the system and divert it to another webpage, whilst saving the details.

The best way I can come up with, to keep the system working yet give me control over most code, is to copy all the page's code into my own html document, and then sit an iframe in the page showing only the preview pane. I then tell the form on my page to submit the details to the iframe. This way, I get the server side scripts still automatically updating the plate as I design it, but have control over the design and functionality.

Here is the page I am working on:
http://www.pristine-plates.co.uk/ebay/test/

Ok, so the problem is this. When I add a left or right logo, the other logo disappears, i.e you can have left or right, but not both. The system normally lets you have both. I guess this is something to do with unique sessions, mainly because every time I add a logo, it restarts part of the system.

Adding the badge is controlled via javascript. You add them by pressing left or right on the badge you want.

Does anyone have any suggestion on how I can get both badges to display at the same time, looking at that link? Or any suggestions about how I can go about doing what I need?

Thank you all in advance

The only thing that comes to mind is to delegate the clicks to the objects in the frame, i.e. when a link is clicked, trigger the click event on the corresponding link in the frame.

But that's a blind try for a workaround, not an insightful solution.

I think that should do the trick Sixtease, thank you for the idea.

Do you have any idea how I would go about doing it? I have tried things like:

<a href="javascript:window.document.getElementById('preview'). forms['options'].elements['option'].value='sidebadgeright-UK_Ireland_Identifiers/ Union-UK.Png';window.getElementById('preview').forms['options']. elements['option'].submit();"


.... but no such luck. I also wonder if using javascript to control an external page, is there away around the "access denied" problem which I think may arise?

Any input would be greatly appreciated

Well... I thought about something like
document.getElementById('preview').getElementsByTagName('a')[
index_of_corresponding_link_in_iframe
].onclick();
The problem is that document.getElementById('preview').getElementsByTagName('a') gives me an empty array... Dunno why, maybe a security issue (those always bug me).

Update: Side thought: This looks more like fit for the JavaScript forum. No Perl issue here.
