Doesn't set class and data- attribute about fancyselect HOT 11 CLOSED

This isn't documented at the moment, but you can pass classes along using a data-class attribute. I'm considering what to do about other data-* attributes, but haven't landed on a solution quite yet. Can you describe your use case for needing to send these along? It might help me figure out a good solution.

from fancyselect.

I was gonna pass those data-* attributes so I can check on the selected option and the value of this attribute and change some part of the page I'm working with...

from fancyselect.

You don't need to use data attributes to check the selected option. Just check it on the select itself as per usual:

$('#my-select').val();

from fancyselect.

not the value of option itself, I use that somewhere else, I needed data-* attrs specially to specify something else than the value of option itself, you can imagine the value of an option is "iPod" and the value of data-category is "Music Player" or something like that...

thanks for the fast response

from fancyselect.

Ah, I see. Now that I'm thinking about it, there's probably no need to pass along data attributes other than data-class anyhow, since you can just access them directly on the select:

var mySelect = $('#my-select');

mySelect.fancySelect();

var someData = mySelect.data('whatever');

Any reason that wouldn't work for your use case?

from fancyselect.

what does this going to return?
var someData = mySelect.data('whatever');
I'm asking this since the list item generated by fancySelect doesn't have the exact attributes that each option itself has

from fancyselect.

If:

<select id="mySelect" data-whatever="something">
    <option>Foo</option>
</select>

Then:

var mySelect = $('#my-select');

mySelect.fancySelect();

var someData = mySelect.data('whatever');
// someData == 'something'

Exactly like using jQuery's data normally.

from fancyselect.

you see It was my mistake if I didn't describe my problem right,

the problem is that I assign some kinda data-* attrs to 'option' elements not the 'select' element itself, just like the example: option is 'iPod' and data-cat of that specific option is 'Music Player'...
your solution returns the data attribute of select element, please tell me where I'm mistaken...

from fancyselect.

Oh, I see. I guess I misunderstood.

You could do something like this:

$('#my-select').on('change', function() {
    var el = $(this),
        cat = el.find('option:selected').data('cat')
});

Again, pretty similar to what you'd to do with a normal select.

EDIT: Updated with cleaner code. Also, working code.

from fancyselect.

I see, I can mange something with that,

thanks, for the time and effort

from fancyselect.

I'm going to leave this open for a bit to remind me to update the docs. Glad I could help.
