Answer 1

You can do the following way. Initially set a variable, lets say checked as false. Then set it to true if the following condition met. Use an if statement to check the variable. Take note: Here submit is the id of the button, main is the id of the form.

$("#submit").click(function() {
  var checked = false;
  if (jQuery('#main input[type=checkbox]:checked').length) {
    checked = true;
  }
  if (!checked) {
    //Do something
  }
});
