How to Submit a Form on Enter Key Press in an AIR Project Using jQuery?

Handling Form Submission on 'Enter' Press with jQuery

Problem:
In an AIR project using HTML/jQuery, submitting a standard login form doesn't work when pressing "Enter." The form contents vanish without being submitted. Is this a Webkit issue or a configuration problem?

Code Example:
The following code was attempted but failed to prevent the clearing behavior or submit the form:

$('.input').keypress(function (e) {
  if (e.which == 13) {
    $('form#login').submit();
  }
});

Solution:
To prevent the default behavior and submit the form on "Enter" press, add the following line to the provided code:

return false;

The modified code:

$('.input').keypress(function (e) {
  if (e.which == 13) {
    $('form#login').submit();
    return false;    // Prevent default behavior
  }
});

Explanation:
"return false" in this context serves the same purpose as calling e.preventDefault() and e.stopPropagation(). It prevents the default behavior of the browser from clearing the form contents and stops event propagation, ensuring that the form submission occurs as intended.
