I have dropdown <select> with id my_dropdown. I allow multi-select. I know how to pull the selected value(s) using jquery:
var values = $('#my_dropdown').val();
This will return an array of values if I select multiple. I also need to get all the values in the dropdown regardless of what is selected. How can I use jquery similarly to get all the values in the dropdown given that id?
How about something like:
var values = [];
$('#my_dropdown option').each(function() {
values.push( $(this).attr('value') );
});
Looks like:
var values = $('#my_dropdown').children('option').map(function(i, e){
return e.value || e.innerText;
}).get();

Reference: .map()
map function +1Example: http://jsfiddle.net/FadHu/
var opts = $('#my_dropdown')[0].options;
var array = $.map(opts, function( elem ) {
return (elem.value || elem.text);
});
The <select> element has a list of the options in its options property. Then use $.map(), which returns an array, to get either the option's value or text property.
(Note the $.map() behaves a little differently from $(element).map(). Can be a little tricky.)
value for some reason is an empty string. Otherwise, most browsers will give you the text if there isn't a value attribute present.
