Hi all, for my latest toy [1] I would really like to get the item IDs (Qxxx) for the items in the dropdown box when editing a claim that points to an item. I can get the item IDs for the search dropdown via the link hrefs, but didn't find anything similar in the "role='menuitem'" <li>s for the edit box. Is there a global data structure with the ID list I could access? Are the IDs attached to DOM nodes via jQuery data()? A hook I can add my function to? Or something else I could use? Alternatively, could you add an attribute (e.g. "itemid='Qxxx'") to the <li> nodes? Shouldn't be too hard, as it couldn't really break anything AFAICT. Could be really handy. Thanks, Magnus [1] http://magnusmanske.de/wordpress/?p=64

There is a global data structure in "wikibase.fetchedEntities", though, this one does not contain all entities ever displayed in the drop-down but only those actually selected at some point. Adding some data-attribute to the li-elements would indeed be a good idea I guess. Cheers, Daniel 2013/9/9 Magnus Manske <magnusmanske(a)googlemail.com>om>:

So how is this currently done? Just via callback on click()? (/me too lazy to read the source) Also, if adding a data attribute to the <li>s is the only way to get that information, could that be part of the next rollout please? Should take only a minute for someone who knows the source. Thanks, Magnus On Mon, Sep 9, 2013 at 2:58 PM, Daniel Werner <daniel.werner(a)wikimedia.de>wrote;wrote:

I guess you are referring to the "wikibase.fetchedEntities" being updated when the user selects an entity there? Not via click, there is a more dedicated event called "entityselectorselect". That one is being caught in "jQuery.valueview.experts.wikibase.EntityIdInput" where we store some basic info about the selected item in our global local store. See "/Wikibase/lib/resources/jquery.valueview.experts.wikibase/experts.wikibase.EntityIdInput.js" for details and all the TODOs we have around that bit of code there.

...

Also, if adding a data attribute to the <li>s is the only way to get that information, could that be part of the next rollout please? Should take only a minute for someone who knows the source.

I will bring it up tomorrow and suggest adding it to our current sprint. 2013/9/9 Magnus Manske <magnusmanske(a)googlemail.com>om>:
