Submitting a Form on "Enter" with jQuery: Resolving the Vanishing Form Issue
You have encountered an issue where pressing "Enter" on your login form causes the form contents to disappear without submitting. This raises questions about whether it is a Webkit issue or a problem with your code.
To address this behavior, you attempted to use the following jQuery code:
$('.input').keypress(function (e) {
if (e.which == 13) {
$('form#login').submit();
}
});
However, this code did not resolve the issue.
Solution:
To fix this issue, you need to add a crucial line in your jQuery code:
$('.input').keypress(function (e) {
if (e.which == 13) {
$('form#login').submit();
return false; //<---- Add this line
}
});
This line prevents the default behavior of the form, namely clearing its content on "Enter." By adding it, the form will now submit upon pressing "Enter" without disappearing.
Understanding Return False:
The "return false" statement accomplishes the same result as calling both e.preventDefault and e.stopPropagation. It tells the browser not to perform the default action (form clearing) and prevents the event from bubbling up the DOM hierarchy.
