Answer 1

in your submit button handler:

ev.preventDefault();
ev.stopPropagation();
var checked = document.querySelectorAll('input[type=checkbox]:checked');
var values = [];
for(var i = 0; i < checked.length; i++) {
  values.push(checked[i].value);
}

window.location = "example.com?values=["+values.join(",")+"]";
