var n = 0;
function save() {
var rtn = document.getElementById('rtn');
rtn.innerHTML = ' Data submitted';
console.log(n + 1);
}

Option 3 Add the disable part in the submit event
$(document).ready(function () {
$("#yourFormId").submit(function () {
$(".submitBtn").attr("disabled", true);
return true;
});
});This doesn’t work if the <button> has a value="" attribute – browsers don’t submit disabled controls (input, button, select, textarea) if they’re disabled, and that happens right after the onsubmit event, not before it.
