jQuery combobox Ever needed a combobox? I mean a real one (ie, you can type into it AND select items)? Here is an excellent blog, explaining the finer details of how it works: http://www.learningjquery.com/2010/06/a-jquery-ui-combobox-under-the-hood
And, then, when you put it in a form, and it doesn’t work, you’ll need this:

Form with nested resources
I don’t do this very often, and I hadn’t used form_for with nested resources before. It seems this doesn’t work:
form_for @post, @comment
But this does:
form_for [@post, @comment]
D’Oh! That one took me a while to find. The example from this link pointed me in the right direction:

jQuery again - val() on a hidden select doesn’t work
Ok, this is really fucking annoying. How is anyone supposed to figure out that this doesn’t work when the select is hidden:
$(“myselect”).val()
But this does:
$(“myselect option:selected”).val()
Do you know how many hours that cost me?!?!?!? P.S. If you are using the combobox (above) this may be important to you.
