AJAX形式部分起作用

Question

I can submit a form like this and it works:

$(document).on('click', '#someLink', function() {
  var frm = $('#myCustomForm');
  frm.submit();
});

However, when I submit the same form like below, the form is not being submitted:

$(document).on('click', '#someLink', function() {
  var frm = $('#myCustomForm');
  frm.submit(function(e) {
    $.ajax({
      type: 'POST',
      url: '/comments/new/',
      dataType: 'application/json',
      data: frm.serialize(),
      success: function(data) {
        alert('successful');
      },
      error: function(data) {
        alert('something went wrong');
      }
    });
    e.preventDefault();
    return false;
  });
});

What am I doing wrong here?

The two codes are complete opposites. frm.submit(function(e) {}) assigns a function to the form submission so you would need to submit the form again.

You just want to run the Ajax code so just run the code.

$(document).on('click', '#someLink', function(e) {
  var frm = $('#myCustomForm');
  $.ajax({
      ...
  });
  e.preventDefault();
});
