How to get an object instance ?

**geemeetheway** · 11-14-2008, 08:47 PM

I'm using stickmanlabs.com's accordion and I want to get the active accordion to do some manipulation.

I need to do something like this :

Code:

var activeAccordion = GetInstanceActiveAccordionOrSomewayToDoIt("AcdordionName");
activeAccordion.activate($$('#vertical_container .accordion_toggle')[0]);

Thank you

Well, I'm not too sure about what would constitute the active accordion. However, if you want to access a given accordion, you would need to create it with a reference, ex:

Code:

var myAccordion = new accordion('#myId');

Once you have that, you can do some things with it using other script code as shown on the demo page.

If you want to somehow have Accordion v2.0 keep track of which of several accordions on a given page was last to be activated by the user, that would be a bit more complex. Unless the author has made some provision for it, it would require additional coding, at the very least a listener for the page.

When I do this, I got two instances of the same object and the accordion got weird beheviors like opening container many time.

If someone can help me make a singleton we that.

That sounds like you have either defined the same accordion more than once or have more than one accordion with the same variable reference. To see what's going on, I would need to see a page that demonstrates the problem:

Please post a link to the page on your site that contains the problematic code so we can check it out.

Please also tell me what to do on your page to get it to misbehave.

Alternatively, you could donate five bucks to the author. It is my understanding (though I could be wrong about this) that's all it would take for him to give you this type of support in a timely manner.

Author's forum is down for now.

I'll try to make a temporary online of this mistake soon. It's on beta version for now.

Thanks!

here the link : http://www.plandematchcommunication.com/temporaire/

If you click on accordion's red tabs, everything is fine. Now, click on the bottom black links to open specific tabs a few time. After, click on the red tabs again and look at the weird behevior.

I think that is because that every time, I got a new instance when this line is proceed :

Code:

var bottomAccordion = new accordion('vertical_container');

How can I open specific tab without make a new instance ?

By declaring it in the global scope to begin with:

Notes: I made some other changes in your code, returning (false) onclick of the 'external toggles', for example. Mid section of page unchanged, removed in the above for brevity.
