If jQuery is an option, you can get an array of the values using .map() like this:

var vals = $("input[name=c1]:checked").map(function(i, cb) {
  return $(cb).val();
}).get();
alert(vals);

vals would contain an array of the values of the checked checkboxes, e.g. [12, 14] if A and C were checked in this:

<input name="c1"  type="checkbox" value="12" /> mediaA
<input name="c1"  type="checkbox" value="13" /> mediaB
<input name="c1"  type="checkbox" value="14" /> mediaC
