Contact Form 7 no longer supports the <code>on_sent_ok</code> and <code>on_submit</code> settings available on the Additional Settings screen as of version 5.0 of CF7. Both settings were deprecated before this release, which was why this plugin was first created. <a href="https://contactform7.com/additional-settings/" rel="nofollow ugc">https://contactform7.com/additional-settings/</a>
This plugin is meant to be a band-aid to quickly get your Additional Settings working. It reads the Additional Settings data and adds a javascript block when the form is output on the page, using DOM Events as suggested by the CF7 author. <a href="https://contactform7.com/dom-events/" rel="nofollow ugc">https://contactform7.com/dom-events/</a>
