问题 I'd like to track how often users download files using Analytics' events, but even though the events seem to have been sent, the tracking .gif doesn't seem to be arriving properly. To download files, users are required to fill out a brief form.

问题 Using jQuery Validate, is there a way to determine if a form is valid without revalidating the form.
