How to use it

The main files of this plugin are caleran.min.js and caleran.min.css, which are generated by compiling and minifying caleran.js and caleran.css. The plugin relies on jQuery and moment.js libraries, also needs to be included before including caleran.min.js.

The font used on this plugin is Roboto, and the icons are provided by Font Awesome which are included remotely from their CDN's. You can change it anyway you want.

The example configuration which can be found in the base index file is:

<link
  href="https://fonts.googleapis.com/css?family=Roboto:300,400,400i,500,700"
  rel="stylesheet"
/>
<link
  href="http://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css"
  rel="stylesheet"
/>
<script
  type="text/javascript"
  src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"
></script>
<script>
  window.jQuery ||
    document.write(
      '<script src="js/jquery-2.1.4.min.js" type="text/javascript"><\/script>'
    );
</script>
<!-- .caleran includes -->
<link href="build/css/caleran.min.css" rel="stylesheet" />
<script src="build/js/moment.min.js"></script>
<script src="build/js/caleran.min.js"></script>
<!-- .end caleran includes -->

Then, to attach a caleran object to an element you desire, use this:

$(".caleran").caleran();

You can customize your plugin with options you provide to the initializing function,

$(".caleran").caleran({ inline: true, startOnMonday: true });

or the element's data-plugin-options property.

<input
  class="caleran"
  data-plugin-options='{"calendarCount":1,"showHeader":true,"showFooter":true}'
  name="calendar-input"
  type="text"
  value="08.08.2017 - 08.09.2017"
/>

Once initalized, you can access the caleran object like this:

var caleran = $(".caleran:eq(3)").data("caleran");
caleran.config.startDate = new Date();
caleran.reDrawCalendars();

Properties

Once you've got the caleran instance object, you can access these properties:

elem [DOM node object]: The HTML dom node which the instance is created on.
$elem [jQuery Object]: jQuery object of the dom node. Equals to $(caleran.elem)

Please Note that if you've chosen a different target element, you will be accessing the initiator element by calling caleran.$elem. Your actual target element would be caleran.config.target.

For example,

var caleran = $("#elem1").caleran();
// caleran.elem will be equal to document.getElementById("elem1") or $("#elem1").get(0);
// caleran.$elem will be equal to $("#elem1");

config [JS Object]: The instance's configuration object. Consists of merging default values and user defined settings. The details of it is explained in the Options section.

These properties are also defined, but not recommended to tinker on.

container [jQuery Object]: This refers to the outermost container element of the instance dropdown or inline instance and the input itself.
header [jQuery Object]: This refers to the header part of the plugin.
footer [jQuery Object]: This refers to the footer part, - not the mobile buttons part - the ranges part of the plugin.
input [jQuery Object]: This refers to the first child of the container, which contains everything except the input which is caleran instantiated on.

Important Notes

I left the caleran object fully accessible to the inner variables, so you can alter the object's config in any event. For example, you can alter the max date of the calendar after first selection like this (limiting the user to select max 7 days of the first selection):

onfirstselect: function(caleran, startDate){
    caleran.config.maxDate = startDate.clone().add(7,"days");
},
onafterselect: function(caleran, startDate, endDate){
    caleran.config.maxDate = null;
}

or another example, disabling previous date selection:

onfirstselect: function(caleran, startDate){
    caleran.config.minDate = startDate.clone();
},
onafterselect: function(caleran, startDate, endDate){
    caleran.config.minDate = null;
}

The cloning is very important when adding or subtracting, because they modify the reference element too! As you can see in the above examples, the startDate and the endDate elements are cloned when defining the maxDate and minDate values. If you don't want to modify the startDate or endDate intentionally, use cloning.
~~Mobile only supports modal like interface. Dropdowns and inline options currently don't work on mobile phones.~~ Added inline support on mobile on version 1.3.1.
~~Mobile versions only show 1 calendar. If you want it to support multiple calendars on mobile or inline support, let me know how it should be designed, and I'll try to put it on the next release.~~ Thanks to ginharja, it's now implemented.
Only one event can be bound using the initialize config object. Multiple events are not supported.
