Checking Number Of Selected Checkboxes

I saw the is function in jQuery, and it returns me, for example, if any of the checkboxes are selected. I need to do a check for how many checkboxes had been selected by the user,

Solution 1:

To get the amount of checkboxes checked and bind to the submit button:

$("#yourButton").click(function(e){
  var n = $("input:checked").length;  //Checkbox count, may need refinedif(n<2) //using n from above.
  {
    e.preventDefault(); 
  }
});

Solution 2:

$(".submitBtn").click(function(event) {
    if ($(":checked").length < 2) {
        event.preventDefault();
    } else {
        $('form').submit();
    }
});
