Change confirmation

The Change Confirmation watches for changes on the given form and display a confimation message to the user when leaving the page with unsaved changes.

Initialize the change confirmation on a form:

$('form').changeConfirmation();

Options:

You can specify the message displayed to the user, in the Javascript call:

$('form').changeConfirmation({ message: 'My confirmation message' });

Or with the data-confirmation-message HTML attribute:

<form data-confirmation-message="My confirmation message">
    <!-- ... -->
</form>

If you don't specify anything, the default message will be: You have unsaved changes. Are you sure you want to quit?

Notes:

• The class changed will be added to the label of the changed field.
• If a form field goes back to its default value, it will be considered as unchanged.
