How to get all checked checkboxes

Answer 1

A simple for loop which tests the checked property and appends the checked ones to a separate array. From there, you can process the array of checkboxesChecked further if needed.

// Pass the checkbox name to the function
function getCheckedBoxes(chkboxName) {
  var checkboxes = document.getElementsByName(chkboxName);
  var checkboxesChecked = [];
  // loop over them all
  for (var i=0; i 0 ? checkboxesChecked : null;
}

// Call as
var checkedBoxes = getCheckedBoxes("mycheckboxes");
