## Installation

    bower i --save air-datepicker

Or you can download files directly from GitHub

## Usage

Include styles and scripts from`/dist`directory:

    <html>
        <head>
            <link href="dist/css/datepicker.min.css" rel="stylesheet" type="text/css">
            <script src="dist/js/datepicker.min.js"></script>

            <!-- Include English language -->
            <script src="dist/js/i18n/datepicker.en.js"></script>
        </head>
    </html>

Datepicker will automatically initialize on elements with class`.datepicker-here`, options may be sent via`data`attributes.

    <input type='text' class="datepicker-here" data-position="right top" />

### Manual initialization

    // Initialization
    $('#my-element').datepicker([options])
    // Access instance of plugin
    $('#my-element').data('datepicker')

## Examples

### Initialization with default options

Example

    <input type='text' class='datepicker-here' data-language='en' />

### Selecting multiple dates

Pass parameter`{multipleDates: true}`for selection of multiple dates. If you want to limit the number of selected dates, pass the desired number`{multipleDates: 3}`.

Example

    <input type="text"
           class="datepicker-here"
           data-language='en'
           data-multiple-dates="3"
           data-multiple-dates-separator=", "
           data-position='top left'/>

### Permanently visible calendar

Initialize plugin on non text input element, such as`<div> … </div>`,or pass the parameter`{inline: true}`.

Example

    <div class="datepicker-here" data-language='en'></div>

### Month selection

Example

    <input type="text"
           class="datepicker-here"
           data-language='en'
           data-min-view="months"
           data-view="months"
           data-date-format="MM yyyy" />

### Minimum and maximum dates

To limit date selection, use`minDate`and`maxDate`, they must receive JavaScript Date object.

Example

    $('#minMaxExample').datepicker({
        language: 'en',
        minDate: new Date() // Now can select only dates, which goes after today
    })

### Range of dates

Use`{range: true}`for choosing range of dates. As dates separator`multipleDatesSeparator`will be used.

For possibility to select same date two times, you should set`{toggleSelected: false}`.

Example

    <input type="text"
        data-range="true"
        data-multiple-dates-separator=" - "
        data-language="en"
        class="datepicker-here"/>

### Disable days of week

For disabling days, use`onRenderCell`.

Example

    // Make Sunday and Saturday disabled
    var disabledDays = [0, 6];

    $('#disabled-days').datepicker({
        language: 'en',
        onRenderCell: function (date, cellType) {
            if (cellType == 'day') {
                var day = date.getDay(),
                    isDisabled = disabledDays.indexOf(day) != -1;

                return {
                    disabled: isDisabled
                }
            }
        }
    })

### Custom cells content

Air Datepicker allows you to change contents of cells like you want. You could use`onRenderCell`for this purpose. Lets add extra elements to several dates, and show `lorem` text when selecting them.

Example

    var eventDates = [1, 10, 12, 22],
        $picker = $('#custom-cells'),
        $content = $('#custom-cells-events'),
        sentences = [ … ];

    $picker.datepicker({
        language: 'en',
        onRenderCell: function (date, cellType) {
            var currentDate = date.getDate();
            // Add extra element, if `eventDates` contains `currentDate`
            if (cellType == 'day' && eventDates.indexOf(currentDate) != -1) {
                return {
                    html: currentDate + '<span class="dp-note"></span>'
                }
            }
        },
        onSelect: function onSelect(fd, date) {
            var title = '', content = ''
            // If date with event is selected, show it
            if (date && eventDates.indexOf(date.getDate()) != -1) {
                title = fd;
                content = sentences[Math.floor(Math.random() * eventDates.length)];
            }
            $('strong', $content).html(title)
            $('p', $content).html(content)
        }
    })

    // Select initial date from `eventDates`
    var currentDate = currentDate = new Date();
    $picker.data('datepicker').selectDate(new Date(currentDate.getFullYear(), currentDate.getMonth(), 10))

### Showing and hiding calendar

For adding some actions while datepicker is showing or hiding, use`onShow`and`onHide`callbacks.

Example

    $('#example-show-hide-callbacks').datepicker({
        language: 'en',
        onShow: function(dp, animationCompleted){
            if (!animationCompleted) {
                log('start showing')
            } else {
                log('finished showing')
            }
        },
        onHide: function(dp, animationCompleted){
            if (!animationCompleted) {
                log('start hiding')
            } else {
                log('finished hiding')
            }
        }
    })

## Timepicker

To enable timepicker use option`{timepicker: true}`- it will add current time and a couple of range sliders by which one can pick time.

By default current user time will be set. This value can be changed by`startDate`parameter.

Example

    <div class="datepicker-here" data-timepicker="true" data-language='en'></div>

More detailed info about timepicker parameters you can find in Options.

### Time format

Time format is defined in localization object or in`timeFormat`parameter. By default (in Russian language) 24 hours format is used. For enabling 12 hours mode you must add`aa`or`AA`symbol in`timeFormat`. After what 'AM' and 'PM' sings will appear in timepicker widget.

Lets use 12 hours mode in Russian language:

Example

    <div class="datepicker-here" data-timepicker="true" data-time-format='hh:ii aa'></div>

### Actions with time

For setting max/min hours or minutes values use`maxHours`,`minHours`,`maxMinutes`,`minMinutes`. You also could set time in`minDate`and`maxDate`. For setting hours you must use values between 0 and 23, event if 12 hours mode is on. Plugin will automatically transform given values to 12 hours format.

Lets create calendar where user can choose time between 09:00 am and 06:00 pm on working days and on Saturday and Sunday between from 10:00 am to 04:00 pm.

Example

    <input type='text' id='timepicker-actions-exmpl' />
    <script>
        // Create start date
        var start = new Date(),
            prevDay,
            startHours = 9;

        // 09:00 AM
        start.setHours(9);
        start.setMinutes(0);

        // If today is Saturday or Sunday set 10:00 AM
        if ([6, 0].indexOf(start.getDay()) != -1) {
            start.setHours(10);
            startHours = 10
        }

        $('#timepicker-actions-exmpl').datepicker({
            timepicker: true,
            language: 'en',
            startDate: start,
            minHours: startHours,
            maxHours: 18,
            onSelect: function (fd, d, picker) {
                // Do nothing if selection was cleared
                if (!d) return;

                var day = d.getDay();

                // Trigger only if date is changed
                if (prevDay != undefined && prevDay == day) return;
                prevDay = day;

                // If chosen day is Saturday or Sunday when set
                // hour value for weekends, else restore defaults
                if (day == 6 || day == 0) {
                    picker.update({
                        minHours: 10,
                        maxHours: 16
                    })
                } else {
                    picker.update({
                        minHours: 9,
                        maxHours: 18
                    })
                }
            }
        })
    </script>

## Localization

You can add your localization to object`$.fn.datepicker.language["my-lang"]`and pass it name to parameter`language`

    // Add custom localization
    $.fn.datepicker.language['my-lang'] = {...}

    // Initialize datepicker with it
    $('.my-datepicker').datepicker({
        language: 'my-lang'
    })

You can also pass localization object directly in`language`

    $('.my-datepicker').datepicker({
        language: {
            days: [...]
            ...
        }
    })

If some fields are missing, they will be taken from default localization object ('Russian').

### Example of localization object

    $.fn.datepicker.language['en'] = {
        days: ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'],
        daysShort: ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'],
        daysMin: ['Su', 'Mo', 'Tu', 'We', 'Th', 'Fr', 'Sa'],
        months: ['January','February','March','April','May','June', 'July','August','September','October','November','December'],
        monthsShort: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
        today: 'Today',
        clear: 'Clear',
        dateFormat: 'mm/dd/yyyy',
