Get all values of a Dropdownlist which is not multiple enabled

Get all values of a Dropdownlist which is not multiple enabled

Hi all, 

I was wondering if it is possible to retrieve all values of a dropdownlist which is not MULTIPLE enabled.
This is the code i have that may work on a multiple enabled dropdownlist.
But in my case, i dont want to allow the user to select more than one value from the dropdownlist. 

var values = []; $('#my_dropdown option').each(function() { values.push( $(this).attr('value') ); });

And on submit, i want to post the entire array of content on the dropdownlist. Is it possible? Someone please guide me.

Thanks in advance!
