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.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
