Why Does My Login Form Disappear Instead of Submitting on \'Enter\'?

Submitting a Form on 'Enter' using jQuery

When dealing with a standard login form in an AIR project utilizing HTML/jQuery, pressing 'Enter' may cause unexpected behavior, such as vanishing form contents without submitting. To address this issue, it's essential to understand potential underlying causes.

The provided code snippet attempts to handle the 'Enter' key event using the '.keypress()' function, but it fails to resolve the disappearing form issue and prevent submission. One potential reason could be the lack of an 'action' attribute in the form.

To resolve this issue effectively, modify the event handler code as follows:

$('.input').keypress(function (e) {
  if (e.which == 13) {
    $('form#login').submit();
    return false;    // Add this line
  }
});

The key addition here is the 'return false' statement. Adding this line essentially prevents the default behavior associated with the 'Enter' key press, which in this case is preventing the form from submitting due to conflicting actions.

As mentioned in the linked StackOverflow answer, 'return false' functions similarly to 'e.preventDefault()' and 'e.stopPropagation()', suppressing default browser behavior and facilitating custom handling of the event.

With this modification, pressing 'Enter' within the login form should correctly submit the form, resolving the initial issue encountered.
