I have a select multiple with some options.
Each option has multiple data- attributes.
I would like to create an array that contains each of its data- values.
For example my code looks a lot like this:

<select multiple id='my_select'>

<option data-my_id='1' data-my_parent='3' data-my_name='option1'>My first option</option>

<option data-my_id='2' data-my_parent='3' data-my_name='option2'>My second option</option>

<option data-my_id='3' data-my_parent='3' data-my_name='option3'>My third option</option>

</select>

And the result I am looking for needs to be something like this:

[1,3,option1], [2,3,option2], [3,3,option3]

I have researched how to create an array with one of the data- attribute value for each of the options, giving me this [1,2,3], but I have been unsuccessful in coming up with what I need.

Thanks a lot!
