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

Map the array is the quickest and cleanest.

var array = $.map($('input[name="locationthemes"]:checked'), function(c){return c.value; })

will return values as an array like:

array => [2,3]

assuming castle and barn were checked and the others were not.
