NEW: AJAX Collapsible Wiki.Tree

[blakeh]

First of all, thanks go to NeilW for his AMAZING CollapsibleTree template. Without which, I wouldn't have even attempted. Anyway, it's pretty much been rewritten... Same comments and structure though.
I had a lot of fun doing it, and I hope you enjoy.
What this does:
It loads the first level of sub-pages and sets their bullets to +. When clicked, it will ask the server for subpages and load them below that item. Simple.
You can use the current page (default) or send in a root page. And, of course, you can specify the slide effect (default: off)

Nice!

Two points:

• Can you make it not add a + if you have no children on that node?
• This is exactly what is needed to do the MSDN style layout that people are asking for!

I can make that happen, but that requires an ajax request for each sub-node. I decided to skip this because it would take far too long to load a list of 100 subpages (We have a 'Glossary' page that has many definitions).

Edit:
Also, I just fixed the XML parsing so it should work in all major browsers.

Isn't there an API which tells you how many pages each child node off a given page has? Could have sworn I saw it somewhere.

http://developer.mindtouch.com/Deki/API_Reference/GET: pages//{pageid}//subpages
Does, but that also returns every page. This takes time. It could take upwards of 1, 2 seconds for 100 or more pages. I can add it... but I don't really want to because of the latency. Now if that api had a limit parameter, it could take very little time.

Edit: I'll post a version in a subpage for testing this.

blakeh - The subpages feature does actually have limit/offset (but it looks like our documentation isn't up to date).

[DreamFeatureParam("offset", "int?", "Number of subpages to skip. Default: 0")]
[DreamFeatureParam("limit", "int?", "Number of subpages to retrieve. (default: 100)")]

For example:
http://developer.mindtouch.com/@api/...mit=2&offset=0

Excellent! Then I can go ahead and play with that.

I'm really not worth humouring, but:

http://developer.mindtouch.com/@api/...PeteE/subpages

(scroll right and see the bolded bit - I guess this is what you get to build the first level anyway?)

<subpages totalcount="45" count="45" href="http://developer.mindtouch.com/@api/deki/pages/1232/subpages">
    <page.subpage id="24925" href="http://developer.mindtouch.com/@api/deki/pages/24925?redirects=0" terminal="false" subpages="false">
        <uri.ui>http://developer.mindtouch.com/User:PeteE/AttachmentTest2</uri.ui>
        <title>AttachmentTest2</title>
        <path>User:PeteE/AttachmentTest2</path>
        <namespace>user</namespace>
    </page.subpage>
    <page.subpage id="29919" href="http://developer.mindtouch.com/@api/deki/pages/29919?redirects=0" terminal="true" subpages="false">
        <uri.ui>http://developer.mindtouch.com/User:PeteE/Bugs</uri.ui>
        <title>Bugs</title>
        <path>User:PeteE/Bugs</path>
        <namespace>user</namespace>
    </page.subpage>

You certainly are worth humoring!
Here's your example. It will be pushed into stable when I can figure out how to add depth to it (instead of just using the boring black dot for every level.)
I limited it to 0 because I saw that there is an attribute on subpages called "totalcount" so I checked to see that there are more than 0. That way only like 50 letters are actually sent. It's so fast!

Edit: I see what you are saying CRB. I'll look into that.

Done and done.
mcraven was having some trouble with his template, and I'm not sure what could be wrong. Here's his post:

When I try and use the template I get the following error:
MindTouch.Deki.Script.DekiScriptBadTypeException: map is not valid; expected uri: line 1, column 8
at MindTouch.Deki.Script.DekiScriptCall.Evaluate(Deki ScriptEnv env)

He has 9.02, the code is in a dekiscript block and he has installed the deki api extension.
