Answer 1

If you want to add parameters without modifying the form, you have to serialize the form, add your parameters and send it with AJAX:

var formData = $("#commentForm").serializeArray();
formData.push({name: "url", value: window.location.pathname});
formData.push({name: "time", value: new Date().getTime()});

$.post("api/comment", formData, function(data) {
  // request has finished, check for errors
  // and then for example redirect to another page
});

See .serializeArray() and $.post() documentation.
