Prevent double clicking submit button
A typical problem with HTML forms that if you click fast enough, you can submit the form twice - or more, mostly if the server response was slow. CiviCRM is no exception.
- Any page that has a standard form - without Ajax. (e.g. Find Contributions or New Contribution or Some of the result actions).
- Click submit button fast enough.
Any thoughts on this?
