## Options

Note All options are accessed via the `data` attribute e.g. `$('#datetimepicker').data("DateTimePicker").OPTION()`

### options()

Returns the components current options object. Note that the changing the values of the returned object does not change the components actual configuration. Use `options(options)` to set the components options massively or the other methods for setting config options individually.

### options([options])

Takes an object variable with option key:value properties and configures the component. Use this to update multiple options on the component.

### date

Returns the component's model current date, a `moment` object or `null` if not set.

#### date([newDate])

Takes `string, Date, moment, null` parameter and sets the components model current moment to it. Passing a `null` value unsets the components model current moment. Parsing of the newDate parameter is made using moment library with the `options.format` and `options.useStrict` components configuration.

##### Throws

- `TypeError` - in case the `newDate` cannot be parsed

##### Emits

- `dp.change` - In case `newDate` is different from current moment

### format

    Default: false

See momentjs' docs for valid formats. Format also dictates what components are shown, e.g. `MM/dd/YYYY` will not display the time picker.

#### format()

Returns the component's `options.format` `string`

#### format(format)

Takes a moment.js format `string` and sets the components `options.format`. This is used for displaying and also for parsing input strings either from the input element the component is attached to or the `date()` function. The parameter can also be a `boolean:false` in which case the format is set to the locale's `L LT`.

Note: this is also used to determine if the TimePicker sub component will display the hours in 12 or 24 format. (if 'a' or 'h' exists in the passed `string` then a 12 hour mode is set)

### dayViewHeaderFormat

    Default: 'MMMM YYYY'

Changes the heading of the datepicker when in "days" view.

#### dayViewHeaderFormat()

Returns a `string` variable with the currently set `options.dayViewHeaderFormat` option.

#### dayViewHeaderFormat(string)

Takes a `string` value.

Used to customize the header of the day view.

### extraFormats

    Default: false

Allows for several input formats to be valid. See this PR.

#### extraFormats()

Returns a `boolean` or array with the `options.extraFormats` option configuration

#### extraFormats(formats)

Takes an array of valid input moment format options.

### stepping

    Default: 1

Number of minutes the up/down arrow's will move the minutes value in the time picker

#### stepping()

Returns a `number` with the `options.stepping` option configuration

#### stepping(number)

Takes a `number`. This be the amount the up/down arrows move the minute value with a time picker.

### min/maxDate

    Default: false
    Accepts: date, moment, string

Prevents date/time selections before this date. Will override `defaultDate` and `useCurrent` if either of these settings are the same day since both options are invalid according to the rules you've selected.

#### minDate()

Returns the currently set moment of the `options.minDate` or `false` if not set

#### minDate(minDate)

Takes a minDate `string, Date, moment, boolean:false` parameter and disallows the user to select a moment that is before that moment. If a `boolean:false` value is passed the `options.minDate` parameter is cleared and there is no restriction to the miminum moment the user can select.

Note: If the minDate parameter is after the currently selected moment the currently selected moment changes to minDate parameter

##### Throws

- `TypeError` - if minDate parameter cannot be parsed using the `options.format` and `options.useStrict` configuration settings

- `TypeError` - if minDate parameter is after `options.maxDate`

##### Emits

- `dp.change` - if the new minDate is after currently selected moment (waiting for #472 to close in order to finalize this part)

- `dp.error` - if the new minDate is after currently selected moment (waiting for #472 to close in order to finalize this part)

#### maxDate()

Returns the currently set moment of the `options.maxDate` or `false` if not set

#### maxDate(maxDate)

Takes a maxDate `string, Date, moment, boolean:false` parameter and disallows the user to select a moment that is after that moment. If a `boolean:false` value is passed `options.maxDate` is cleared and there is no restriction to the maximum moment the user can select.

Note: If maxDate is before the currently selected moment the currently selected moment changes to maxDate

##### Throws

- `TypeError` - if maxDate parameter cannot be parsed using the `options.format` and `options.useStrict` configuration settings

- `TypeError` - if maxDate parameter is before `options.minDate`

##### Emits

- `dp.change` - if the new maxDate is after currently selected moment (waiting for #472 to close in order to finalize this part)

- `dp.error` - if the new maxDate is after currently selected moment (waiting for #472 to close in order to finalize this part)

### useCurrent

    Default: true

On `show`, will set the picker to the current date/time.

#### useCurrent()

Returns a `boolean` or `string` with the `options.useCurrent` option configuration

#### useCurrent(boolean or string)

Takes a `boolean` or `string`. If a `boolean` true is passed and the components model moment is not set (either through `setDate` or through a valid value on the input element the component is attached to) then the first time the user opens the datetimepicker widget the value is initialized to the current moment of the action. If a false `boolean` is passed then no initialization happens on the input element. You can select the granularity on the initialized moment by passing one of the following strings (`'year', 'month', 'day', 'hour', 'minute'`) in the variable.

If for example you pass `'day'` to the `setUseCurrent` function and the input field is empty the first time the user opens the datetimepicker widget the input text will be initialized to the current datetime with day granularity (ie if currentTime = `2014-08-10 13:32:33` the input value will be initialized to `2014-08-10 00:00:00`)

Note: If the `options.defaultDate` is set or the input element the component is attached to has already a value that takes precedence and the functionality of `useCurrent` is not triggered!

### collapse

    Default: true

Using a Bootstraps collapse to switch between date/time pickers.

#### collapse()

Returns a `boolean` of the `options.sideBySide`.

#### collapse(collapse)

#### locale(newLocale)

Takes a `string` of any valid moment locale e.g. `de` for German.

##### Throws

### defaultDate

    Default: false
    Accepts: date, moment, string

#### disabledDates()

Returns an array with the currently set disabled dates on the component.

#### disabledDates(dates)

Takes an `[` `string` or `Date` or `moment` `]` of values and disallows the user to select those days. Setting this takes precedence over `options.minDate`, `options.maxDate` configuration. Also calling this function removes the configuration of options.enabledDates if such exist.

Note: These values are matched with `Day` granularity.

#### enabledDates()

Returns an array with the currently set enabled dates on the component.

#### enabledDates(dates)

Takes an `[` `string` or `Date` or `moment` `]` of values and allows the user to select only from those days. Setting this takes precedence over `options.minDate`, `options.maxDate` configuration. Also calling this function removes the configuration of options.disabledDates if such exist.
