use jQuery to get values of selected checkboxes

Question

I want to loop through the checkboxgroup \'locationthemes\' and build a string with all selected values. So when checkbox 2 and 4 are selected the result would be: \"3,8\"

Answer 1

Using jquery's map function

var checkboxValues = [];
$('input[name=checkboxName]:checked').map(function() {
            checkboxValues.push($(this).val());
});
