The API§

You can play with the picker API to extend and create custom functionality:

var $input = $('.datepicker').pickadate()

// Use the picker object directly.
var picker = $input.pickadate('picker')
picker.methodName(argument1, argument2, ...)
picker.objectName

// Or pass through the element’s plugin data.
$input.pickadate(methodName, argument1, argument2, ...)
$input.pickadate(objectName)

Methods§

There are eleven methods available on the picker:

1. open
2. close
3. start
4. stop
5. render
6. clear
7. get
8. set
9. on
10. off
11. trigger

All these methods (except get) return the picker object and are therefore chainable:

picker.open().clear().close()...

Objects§

There are four objects available through the picker:

1. $node
2. $root
3. _hidden
4. component

The Methods§

Open and Close§

Open and close the picker holder. To check if it’s already open, use the get method.

picker.open()
picker.close()

// If a “click” is involved, prevent the event bubbling.
event.stopPropagation()

// If we want to maintain focus on the input,
// prevent the default action on “mousedown”.
event.preventDefault()

Open

Close with focus§

Close the picker while keeping focus on the input element by passing a truth-y argument.

picker.close(true)

Close with focus

Open without focus§

Open the picker without focusing onto the input element by passing false as the first argument. Opening the picker this way, there’s a few things to note:

(1) The only way to close it is with a separate custom binding – in this example, on document click.

(2) The “opening” events are still triggered – however, using the get method to see if the picker is open will return false.

(3) If any of the picker elements is focused/clicked, it resumes normal behavior.

picker.open(false)
$(document).on('click', function() {
    picker.close()
})

Open without focus

Start and Stop§

Destroy and rebuild the picker. To check if it’s already started, use the get method.

picker.stop()
picker.start()

Stop

Render§

Refresh the picker after adding something to the holder.

picker.render()

Add stuff

By default, only the “face” of the picker (i.e. the box element), has it’s contents re-rendered. To render the entire picker from the root up, pass true as the first argument:

picker.render(true)

Clear§

Clear the value in the picker’s input element.

picker.clear()

Clear

This is a shorthand that uses the set method behind the scenes.

Get§

Get the properties, objects, and states of the picker.

picker.get(thing)

The thing argument is an optional string and can be one of the following:

• value (default)
• select *
• highlight *
• view *
• min *
• max *
• open
• start
• id
• disable
• enable

* Item Objects§

The things denoted in the list above with an asterisk (*) return a picker item object that can be formatted by passing a second string argument using the date or time formatting rules:

picker.get(thing, format)

Each “date” or “time” within the picker has an item object accompanying it behind the scenes.

Here’s a date picker item object for 20 April, 2013:

{
    // The full year.
    year: 2013,

    // The month with zero-as-index.
    month: 3,

    // The date of the month.
    date: 20,

    // The day of the week with zero-as-index.
    day: 6,

    // The underlying JavaScript Date object.
    obj: { 'Sat, 20 Apr 2013 04:00:00 GMT' },

    // The “pick” value used for comparisons.
    pick: 1366430400000
}

Here’s a time picker item object for 4:20 PM:

{
    // Hour of the day from 0 to 23.
    hour: 16,

    // The minutes of the hour from 0 to 59 (based on the interval).
    mins: 20,

    // The “pick” value used for comparisons.
    pick: 980
}

Get value§

Returns the string value of the picker’s input element.

picker.get() // Short for `picker.get('value')`.

Log the value

Get select§

Returns the item object or formatted string of the date that is visually selected.

Defaults to null when there’s no value.

picker.get('select')
picker.get('select', 'yyyy/mm/dd')

Log the selectLog the select formatted

Get highlight§

Returns the item object or formatted string of the date that is visually highlighted.

Defaults to “today” (or “now” for the time picker) when there’s no value.

picker.get('highlight')
picker.get('highlight', 'yyyy/mm/dd')

Log the highlightLog the highlight formatted

Get view§

Returns the item object or formatted string of the date that determines the current view.

Defaults to the first day of the current month (or “now” for the time picker) when there’s no value.

picker.get('view')
picker.get('view', 'yyyy/mm/dd')

Log the viewLog the view formatted

Get min§

Returns the item object or formatted string of the date that determines the lower limit.

Defaults to a -Infinity item object when it is not explicitly set in the options or through the picker’s API.

picker.get('min')
picker.get('min', 'yyyy/mm/dd')

Log the minLog the min formatted

Get max§

Returns the item object or formatted string of the date that determines the upper limit.

Defaults to an Infinity item object when it is not explicitly set in the options or through the picker’s API.

picker.get('max')
picker.get('max', 'yyyy/mm/dd')

Log the maxLog the max formatted

Get open§

Returns a boolean value of whether the picker is open or not.

picker.get('open')

Log the open state

Get start§

Returns a boolean value of whether the picker has started or not.

picker.get('start')

Log the start stateStop picker

Get id§

Returns a unique string that is the ID of the picker and it’s element. If the element has no ID, it is set to something random.

picker.get('id')

Log the picker ID

Get disable and enable§

Both these things work together to determine which item objects to disable on the picker:

// Array passed in options to disable dates
var datesToDisable = [ 1, 4, 7, [2013,3,8], [2013,3,19], new Date(2013,3,26) ]

// Returns `1` to represent a base “enabled” state
picker.get('enable')

// Returns the collection of dates to disable
picker.get('disable')

Log the base state and collection

However, when all dates are disabled and a select few are enabled, it behaves differently:

// Array passed in options to disable all dates except a few
var datesToDisable = [ true, 1, 4, 7, [2013,3,8], [2013,3,19], new Date(2013,3,26) ]

// Returns `-1` to represent a base “flipped” state
picker.get('enable')

// Returns the collection of dates to *not* disable
picker.get('disable')

Log the base state and collection

Set§

Set the properties, objects, and states of the picker.

// One at a time
picker.set(thing, value)

// Multiple at once
picker.set({
    thing: value,
    thing: value,
    thing: value
})

The value is based on the thing being set. The thing, is a string that can be:

• clear
• select *
• highlight *
• view
• min *
• max *
• disable *
• enable *
• interval (time picker only) *

* cascading changes§

When the things denoted in the list above with an asterisk (*) are set, they cascade into updating other things using the same value.

muted callbacks§

By default, any callbacks bound with the on method will be fired when it’s relevant thing is set. To silenty set a thing, pass an options object with the muted parameter set to true:

// One at a time
picker.set(thing, value, { muted: true })

// Multiple at once
picker.set({
    thing: value,
    thing: value,
    thing: value
}, { muted: true })

Set clear§

Clear the value in the picker’s input element.

picker.set('clear')

Clear

This is the full form of the clear method.

Set select§

Setting select has cascading changes that update the highlight, the view, and the value of the input element based on the settings format.

Select a date item object§

// Using arrays formatted as [YEAR,MONTH,DATE].
picker.set('select', [2013,3,20])

You can disable sets of dates and then enable the entire set or specific dates within those sets by the following methods:

• Specific dates:

  picker.set('disable', [
  
      // Using a collection of arrays formatted as [YEAR,MONTH,DATE]
      [2014,9,3], [2014,9,9], [2014,9,20],
  
      // Using JavaScript Date objects
      new Date(2013,9,13), new Date(2013,9,24)
  ])
  picker.set('enable', [
      [2014,9,9],
      [2014,9,13],
      new Date(2013,9,20)
  ])

  Disable specific datesEnable specific dates

• Ranges of dates:

  picker.set('disable', [
  
      // Using integers as the days of the week (1 to 7)
      1, 4, 7,
  
      // Using a range object with a “from” and “to” property
      { from: [2014,2,14], to: [2014,2,27] }
  ])
  picker.set('enable', [
      4,
      { from: [2014,2,24], to: [2014,2,27] }
  ])

Disable/enable times §

You can disable sets of times and then enable the entire set or specific times within those sets by the following methods:

• Specific times:

  picker.set('disable', [
  
      // Using a collection of arrays formatted as [HOUR,MINUTES]
      [2,30], [4,30], [9,0],
  
      // Using JavaScript Date objects
      new Date(2013,9,13,6), new Date(2013,9,13,12,30)
  ])

  // Enable all the dates
  picker.set('enable', true)
  picker.set('disable', false)

  Disable all timesEnable all times

Enable an element within a disabled range §

When a date or time you want to enable falls within a disabled range, add the inverted property to the item:

picker.set('disable', [

    // Disable all Mondays, except November 17th, 2013.
    1, [2013, 10, 17, 'inverted'],

    // Disable all dates from March 2nd, 2014 to March 28th, 2014
    // except for March 10th and all between March 14th and March 23rd.
    { from: [2014, 2, 2], to: [2014, 2, 28] },
    [2014, 2, 10, 'inverted'],
    { from: [2014, 2, 14], to: [2014, 2, 23], inverted: true }
])

picker.set('disable', [

    // Disable all times from 1:00 AM to 1:59 AM, except 1:30 AM.
    1, [1, 30, 'inverted'],

    // Disable all times from 3:00 AM to 6:00 PM except
    // for 4:30 AM and all between 7:30 AM and 11:30 AM.
    { from: [3,0], to: [18,0] },
    [4, 30, 'inverted'],
    { from: [7,30], to: [11,30], inverted: true }
])

Set interval§

For the time picker only, you can change the interval between each time display.

Setting interval has cascading changes on the select, highlight, and view only when the particular item object goes out of range.

// Using integers representing the interval length in minutes
picker.set('interval', 15)
picker.set('interval', 20)
picker.set('interval', 120)

Set it to 15Set it to 20Set it to 120

The Events and Callbacks§

Event on§

Bind callbacks to get fired off when the relative picker method is called (unless if the callback is “muted”):

// One at a time
picker.on(methodName, function() { … })

// Multiple at once
picker.on({
    methodName: function() { … },
    methodName: function() { … },
    methodName: function() { … }
})

The methodName can be open, close, render, start, stop, or set.

Within scope of these callbacks, this refers to the picker object – and for most events, no arguments are passed.

The only exception is the set method, which is passed an argument that provides more context as to what is being “set”.

Event callbacks as bindings§

After the picker has been initiated, callbacks to events can be set using the on method:

picker.on({
    open: function() {
        console.log('Opened up!')
    },
    close: function() {
        console.log('Closed now')
    },
    render: function() {
        console.log('Just rendered anew')
    },
    stop: function() {
        console.log('See ya')
    },
    set: function(thingSet) {
        console.log('Set stuff:', thingSet)
    }
})

Stop

Event callbacks as options§

Before the picker has initiated, callbacks to events can be set by passing them as options when invoking the picker:

$('.datepicker').pickadate({
    onOpen: function() {
        console.log('Opened up!')
    },
    onClose: function() {
        console.log('Closed now')
    },
    onRender: function() {
        console.log('Just rendered anew')
    },
    onStart: function() {
        console.log('Hello there :)')
    },
    onStop: function() {
        console.log('See ya')
    },
    onSet: function(thingSet) {
        console.log('Set stuff:', thingSet)
    }
})

Stop

Event off§

Unbind callbacks that are bound using the on method:

picker.off(methodName, methodName, methodName, ...)

The methodName can be open, close, render, start, stop, or set.

picker.on('open', function() {
    console.log('Even when I’m opened, I’m not logged..')
})
picker.off('open')

Event trigger§

Trigger an event’s callbacks that have been queued up:

picker.on('open', function() {
    console.log('This logs without opening!')
})
picker.trigger('open')

Trigger open callback

Optionally, you can also pass some data to the method being triggered:

picker.on('open', function(data) {
    console.log('This logs without opening with this data:', data)
})
picker.trigger('open', { some: 'value' })

Trigger open callback with data

The Objects§

Object $node§

This is the picker’s relative input element wrapped as a jQuery object.

picker.$node

Get the node

Object $root§

This is the picker’s relative root holder element wrapped as a jQuery object.

picker.$root

Get the root

Object _hidden§

This is the picker’s relative hidden element, which is undefined if there’s no formatSubmit option.

There should be no reason to use this – it’s mostly for internal use. If you have a valid reason for using this, please mention it in the Issues.

Object component§

This is the picker’s relative component constructor that builds the date or time picker. This API is in flux – so avoid using it for now.
