Hey everyone,

I’ve been mucking around with FullCalendar recently and decided to share one of the prototypes I’ve ended up with. It basically lets the user change the events without having to do a postback. A user simply has to click the event, type in the changes and hit update.

I’ve posted the code below, however there’s also a zip which is a little easier to manage. Note that you’ll probably want to clean it up a little if you plan to use it in production. The following libraries and plugins are also used:
– jQuery
– jQuery UI
– jQuery FullCalendar
– jQuery miniColors

What it Looks Like:

How to Use It:

It’s all pretty straight forward, but just in case any one runs into issues there are two parts to this example. First, you generate an event template. You can then drag and drop this template onto the calendar as many times as you want.

The second part allows you to edit existing events without posting back to the server. To do this, simply click an event and then make the necessary adjustments using the top panel on the right. Once you’re done, just press update event.

The example uses the standard title property, but also includes a few others: descriptions, price, available. You can change/remove these to suit your needs, just remember to pull them out of the JavaScript as well.
