## Examples

- Basic Initializations
- Using Timezones
- Slider Modifications
- Alternate Fields
- Time Restraints
- Utilities

### Basic Initializations

Add a simple datetimepicker to jQuery UI's datepicker

    $('#basic_example_1').datetimepicker();

Add only a timepicker:

    $('#basic_example_2').timepicker();

Format the time:

    $('#basic_example_3').datetimepicker({
    	timeFormat: "hh:mm tt"
    });

### Using Timezones

Simplest timezone usage:

    $('#timezone_example_1').datetimepicker({
    	timeFormat: 'hh:mm tt z'
    });

Define your own timezone options:

    $('#timezone_example_2').datetimepicker({
    	timeFormat: 'HH:mm z',
    	timezoneList: [
    			{ value: -300, label: 'Eastern'},
    			{ value: -360, label: 'Central' },
    			{ value: -420, label: 'Mountain' },
    			{ value: -480, label: 'Pacific' }
    		]
    });

You may also use timezone string abbreviations for values. This should be used with caution. Computing accurate javascript Date objects may not be possible when trying to retrieve or set the date from timepicker (see setDate and getDate examples below). For simple input values however this should work.

    $('#timezone_example_3').datetimepicker({
    	timeFormat: 'HH:mm z',
    	timezone: 'MT',
    	timezoneList: [
    			{ value: 'ET', label: 'Eastern'},
    			{ value: 'CT', label: 'Central' },
    			{ value: 'MT', label: 'Mountain' },
    			{ value: 'PT', label: 'Pacific' }
    		]
    });

### Slider Modifications

Add a grid to each slider:

    $('#slider_example_1').timepicker({
    	hourGrid: 4,
    	minuteGrid: 10,
    	timeFormat: 'hh:mm tt'
    });

Set the interval step of sliders:

    $('#slider_example_2').datetimepicker({
    	timeFormat: 'HH:mm:ss',
    	stepHour: 2,
    	stepMinute: 10,
    	stepSecond: 10
    });

Add sliderAccess plugin for touch devices:

    $('#slider_example_3').datetimepicker({
    	addSliderAccess: true,
    	sliderAccessArgs: { touchonly: false }
    });

Use dropdowns instead of sliders. By default if slider is not available dropdowns will be used.

    $('#slider_example_4').datetimepicker({
    	controlType: 'select',
    	timeFormat: 'hh:mm tt'
    });

Create your own control by implementing the create, options, and value methods. If you want to use your new control for all instances use the $.timepicker.setDefaults({controlType:myControl}). Here we implement jQueryUI's spinner control (jQueryUI 1.9+).

    var myControl=  {
    	create: function(tp_inst, obj, unit, val, min, max, step){
    		$('<input class="ui-timepicker-input" value="'+val+'" style="width:50%">')
    			.appendTo(obj)
    			.spinner({
    				min: min,
    				max: max,
    				step: step,
    				change: function(e,ui){ // key events
    						// don't call if api was used and not key press
    						if(e.originalEvent !== undefined)
    							tp_inst._onTimeChange();
    						tp_inst._onSelectHandler();
    					},
    				spin: function(e,ui){ // spin events
    						tp_inst.control.value(tp_inst, obj, unit, ui.value);
    						tp_inst._onTimeChange();
    						tp_inst._onSelectHandler();
    					}
    			});
    		return obj;
    	},
    	options: function(tp_inst, obj, unit, opts, val){
    		if(typeof(opts) == 'string' && val !== undefined)
    			return obj.find('.ui-timepicker-input').spinner(opts, val);
    		return obj.find('.ui-timepicker-input').spinner(opts);
    	},
    	value: function(tp_inst, obj, unit, val){
    		if(val !== undefined)
    			return obj.find('.ui-timepicker-input').spinner('value', val);
    		return obj.find('.ui-timepicker-input').spinner('value');
    	}
    };

    $('#slider_example_5').datetimepicker({
    	controlType: myControl
    });

### Alternate Fields

Alt field in the simplest form:

    $('#alt_example_1').datetimepicker({
    	altField: "#alt_example_1_alt"
    });

With datetime in both:

    $('#alt_example_2').datetimepicker({
    	altField: "#alt_example_2_alt",
    	altFieldTimeOnly: false
    });

Format the altField differently:

    $('#alt_example_3').datetimepicker({
    	altField: "#alt_example_3_alt",
    	altFieldTimeOnly: false,
    	altFormat: "yy-mm-dd",
    	altTimeFormat: "h:m t",
    	altSeparator: " @ "
    });

With inline mode using altField:

    $('#alt_example_4').datetimepicker({
    	altField: "#alt_example_4_alt",
    	altFieldTimeOnly: false
    });

### Time Restraints

Set the min/max hour of every date:

    $('#rest_example_1').timepicker({
    	hourMin: 8,
    	hourMax: 16
    });

Set the min/max date numerically:

    $('#rest_example_2').datetimepicker({
    	numberOfMonths: 2,
    	minDate: 0,
    	maxDate: 30
    });

Set the min/max date and time with a Date object:

    $('#rest_example_3').datetimepicker({
    	minDate: new Date(2010, 11, 20, 8, 30),
    	maxDate: new Date(2010, 11, 31, 17, 30)
    });

Restrict a start and end date by using onSelect and onClose events for more control over functionality:

For more examples and advanced usage grab the Handling Time eBook.

    var startDateTextBox = $('#rest_example_4_start');
    var endDateTextBox = $('#rest_example_4_end');

    startDateTextBox.datetimepicker({
    	timeFormat: 'HH:mm z',
    	onClose: function(dateText, inst) {
    		if (endDateTextBox.val() != '') {
    			var testStartDate = startDateTextBox.datetimepicker('getDate');
    			var testEndDate = endDateTextBox.datetimepicker('getDate');
    			if (testStartDate > testEndDate)
    				endDateTextBox.datetimepicker('setDate', testStartDate);
    		}
    		else {
    			endDateTextBox.val(dateText);
    		}
    	},
    	onSelect: function (selectedDateTime){
    		endDateTextBox.datetimepicker('option', 'minDate', startDateTextBox.datetimepicker('getDate') );
    	}
    });
    endDateTextBox.datetimepicker({
    	timeFormat: 'HH:mm z',
    	onClose: function(dateText, inst) {
    		if (startDateTextBox.val() != '') {
    			var testStartDate = startDateTextBox.datetimepicker('getDate');
    			var testEndDate = endDateTextBox.datetimepicker('getDate');
    			if (testStartDate > testEndDate)
    				startDateTextBox.datetimepicker('setDate', testEndDate);
    		}
    		else {
    			startDateTextBox.val(dateText);
    		}
    	},
    	onSelect: function (selectedDateTime){
    		startDateTextBox.datetimepicker('option', 'maxDate', endDateTextBox.datetimepicker('getDate') );
    	}
    });

### Utilities

Get and Set Datetime with the getDate and setDate methods. This example uses timezone to demonstrate the timepicker regonizes the timezones and computes the offsets when getting and setting.

    var ex13 = $('#utility_example_1');

    ex13.datetimepicker({
    	timeFormat: 'hh:mm tt z',
    	separator: ' @ ',
    	showTimezone: true
    });

    $('#utility_example_1_setdt').click(function(){
    	ex13.datetimepicker('setDate', (new Date()) );
    });

    $('#utility_example_1_getdt').click(function(){
    	alert(ex13.datetimepicker('getDate'));
    });

Use the utility function to format your own time. $.datepicker.formatTime(format, time, options)

format
  required - string represenation of the time format to use
time
  required - hash: { hour, minute, second, millisecond, timezone }
options
  optional - hash of any options in regional translation (ampm, amNames, pmNames..)

Returns a time string in the specified format.

    $('#utility_example_2').text(
    	$.datepicker.formatTime('HH:mm z', { hour: 14, minute: 36, timezone: '+2000' }, {})
    );

Use the utility function to parses a formatted time. $.datepicker.parseTime(format, timeString, options)

format
  required - string represenation of the time format to use
time
  required - time string matching the format given in parameter 1
options
  optional - hash of any options in regional translation (ampm, amNames, pmNames..)

Returns an object with hours, minutes, seconds, milliseconds, timezone.

    $('#utility_example_3').text(JSON.stringify(
    	$.datepicker.parseTime('HH:mm:ss:l z', "14:36:21:765 +2000", {})
    ));
