jQuery: make checkboxes act like radio buttons?

Question

Is there a way to make checkboxes act like radio buttons? I assume this could be done with jQuery?

Answer 1

Updated the script (via answer from Tomislav) so you also can uncheck ALL checkboxes. Just added a .not(this) and removed the line where the the current checkbox is checked.

$('form').each(function() { // iterate forms
  var $this = $(this);
  $this.find('input:checkbox').click(function() {
    var group = 'input:checkbox[name="' + $(this).attr('name') + '"]';
    $this.find(group).not(this).attr('checked', false).prop('checked', false); // also use prop, for real Property change
  });
});
