问题
I am implementing a calendar and I have encountered some difficulties because I am learning JavaScript alone and I have not mastered yet.
My problem is this: I can create the event and save it in the database, but the event and the color of it ... do not appear on the calendar ... can someone find out the solution or where is the problem? If possible ... to create events ... being the color of this event always in random color?

回答1:
Your event objects do not conform to the specification laid out at https://fullcalendar.io/docs/event-object .
Here is the problem:
$.each(data, function (i, v) {
events.push({
eventID: v.ID_Reserva,
clienteID: v.ID_Cliente,
quartoID: v.ID_Quarto,
inicio: moment(v.DataEntrada),
fim: v.DataSaida != null ? moment(v.DataSaida) : null,
noites: v.NumeroNoites,
pessoas: v.NumeroPessoas,
preço: v.Preço,
obs: v.Observaçoes
});
});
FullCalendar doesn't speak Portuguese. The event property names have to match the ones in the documentation otherwise it will ignore them. It doesn't magically know that inicio means start, for example. This means it cannot read any start time from your event, and therefore it doesn't know how to display it on the calendar.
Again as per the documentation, your events are also required to have a title, which you didn't appear to include at all.
Try this instead:
$.each(data, function (i, v) {
events.push({
id: v.ID_Reserva,
clienteID: v.ID_Cliente,
quartoID: v.ID_Quarto,
title: '[You need to choose something to put here]',
start: moment(v.DataEntrada),
end: v.DataSaida != null ? moment(v.DataSaida) : null,
noites: v.NumeroNoites,
pessoas: v.NumeroPessoas,
preço: v.Preço,
obs: v.Observaçoes
});
});
I have just changed the properties which matter for displaying the event. For other custom properties, you can call them anything you like, but the ones which have a defined purpose in fullCalendar must be named correctly.
P.S. You may need to change the code in your eventDrop function in a similar way.
