events (as a json feed)
=======================

A URL of a JSON feed that the calendar will fetch [Event Objects](Event_Object) from.

FullCalendar will visit the URL whenever it needs new event data.
This happens when the user clicks prev/next or changes views.
FullCalendar will determine the date-range it needs events for and will
pass that information along in GET parameters.

The GET parameter names will be determined by the [startParam]() and [endParam]() options.
(`"start"` and `"end"` by default).

The value of the parameters will always be UNIX timestamps (seconds since 1970).

Consider the following script:

	$('#calendar').fullCalendar({
		events: '/myfeed.php'
	});
	
Here is a URL that FullCalendar might visit:
	
`/myfeed.php?start=1262332800&end=1265011200&_=1263178646`

The `_` parameter is automatically inserted to prevent the browser from
caching the result ([more below](#caching)).

If you need to access a feed that is in a different domain, you can use JSONP
with a `?` in your URL (see the JSONP discussion in [$.ajax](http://api.jquery.com/jQuery.ajax/)).

Extended Form
-------------

Since version 1.5, you are able to specify [Event Source options](Event_Source_Object#options).
This often comes in handy when you are using the [eventSources]() option to
specify multiple event sources and you want certain options to only apply to certain sources.
However, to do this, you must write things a little differently:

	$('#calendar').fullCalendar({
		
		eventSources: [
		
			// your event source
			{
				url: '/myfeed.php', // use the `url` property
				color: 'yellow',    // an option!
				textColor: 'black'  // an option!
			}
			
			// any other sources...
		
		]
		
	});
	
A list of general Event Source options can be found [here](Event_Source_Object#options).
<span id='options'>However, there are additional options that apply specifically to JSON feeds:</span>

<table>
<tr>
<th>
startParam
</th>
<td markdown='1'>
Sets the [startParam]() option, but only for this source.
</td>
</tr>
<tr>
<th>
endParam
</th>
<td markdown='1'>
Sets the [endParam]() option, but only for this source.
</td>
</tr>
</table>

jQuery $.ajax options
---------------------

You can also specify any of the [jQuery $.ajax](http://api.jquery.com/jQuery.ajax/) options within the same object!
This allows you to easily pass additional parameters to your feed script, as well as
listen to ajax callbacks:

	$('#calendar').fullCalendar({
		
		eventSources: [
		
			// your event source
			{
				url: '/myfeed.php',
				type: 'POST',
				data: {
					custom_param1: 'something',
					custom_param2: 'somethingelse'
				},
				error: function() {
					alert('there was an error while fetching events!');
				},
				color: 'yellow',   // a non-ajax option
				textColor: 'black' // a non-ajax option
			}
			
			// any other sources...
			
		]
	
	});

Here is the same example, but using the single-source `events` option instead:

	$('#calendar').fullCalendar({
		
		events: {
			url: '/myfeed.php',
			type: 'POST',
			data: {
				custom_param1: 'something',
				custom_param2: 'somethingelse'
			},
			error: function() {
				alert('there was an error while fetching events!');
			},
			color: 'yellow',   // a non-ajax option
			textColor: 'black' // a non-ajax option
		}
	
	});
	
Caching
-------

<span id='caching'></span>
By default, FullCalendar will insert a `_` parameter into the URL of the request to prevent
the browser from caching the response.
FullCalendar achieves this internally by setting the $.ajax parameter to `false`.

If you would like to counteract this and prevent the `_` parameter, you can set the `cache` option to `true`:


	$('#calendar').fullCalendar({
		
		events: {
			url: '/myfeed.php',
			cache: true
		}
	
	});
