Events : quick edit schedule data

[agilare]

It would ease a lot update of events by organizers if schedule values could be edited inline and saved by ajax, directly in pages agenda, lieu, organisateur, copier...

Table : evenements
Fields : horaire_debut, horaire_fin, horaire_complement

For each event :

• onclick horaire area : show 3 form inputs (start, end type time & 1 complement type text) filled with val of horaire from html, and a submit "Enregistrer" button
• onclick out of the form area : hide and empty form inputs and submit buttons then restore horaire html
• onsubmit : ajax save 3 input values+ hide form + replace in html val of horaire with new values + show horaire html
