How do I clear/reset the selected dates on the jQuery UI Datepicker calendar?

Question

How do I reset the datepicker calendar values?.. The min and max date restrictions?

The problem is that when I clear the dates (by deleting the textbox values), the previous date restrictions are still applied.

I've been sorting through the documentation and nothing jumped out as a solution. I also wasn't able to find a quick fix on a SO/google search

Solution:

// from & to input textboxes with datepicker enabled
var dates = $("input[id$='dpFrom'], input[id$='dpTo']");

// #clearDates is a button to clear the datepickers
$('#clearDates').on('click', function(){
    dates.attr('value', '');
    dates.each(function(){
        $.datepicker._clearDate(this);
    });
});​​

_.clearDate() is a private method of the DatePicker object. You won't find it in the public API on jQuery UI's website, but it works like a charm.

Answer 1

I was trying to accomplish this very thing, that is, empty the datepicker so that filters entered by the user could be removed. Googling a bit I found this sweet piece of code:

You can add the clear feature even on read only fields. Just add the following code to your datepicker:

}).keyup(function(e) {
    if(e.keyCode == 8 || e.keyCode == 46) {
        $.datepicker._clearDate(this);
    }
});

People will be able to highlight (even Read Only fields) and then use backspace or delete key to remove the date using _clearDate function.

Answer 2

Did you try:

$('selector').datepicker('setDate', null);

That should work according to the API documentation

Answer 3

you just need to set the options again to null:

dates.datepicker( "option" , {
    minDate: null,
    maxDate: null} );

I've changed your jsfiddle: http://jsfiddle.net/tF5MH/9/

Answer 4

$('.date').datepicker('setDate', null);

Answer 5

Try changing the clearing code to:

$('#clearDates').on('click', function(){
    dates.attr('value', '');
    $("input[id$='dpFrom'], input[id$='dpTo']").datepicker( "option", "maxDate", null );
    $("input[id$='dpFrom'], input[id$='dpTo']").datepicker( "option", "minDate", null );
});

Answer 6

Try This, This Will Add Clear Button On Jquery Calender That Will Clear Date.

$("#DateField").datepicker({
    showButtonPanel: true,
    closeText: 'Clear',
         onClose: function (dateText, inst) {
        if ($(window.event.srcElement).hasClass('ui-datepicker-close'))
        {
            document.getElementById(this.id).value = '';
        }
    }
});

Answer 7

Reset the max date attributes on your datepicker when you click clear.

From jquery website

Get or set the maxDate option, after init.

    //getter
    var maxDate = $( ".selector" ).datepicker( "option", "maxDate" );
    //setter
    $( ".selector" ).datepicker( "option", "maxDate", '+1m +1w' );

Answer 8

The obvious answer was the one that worked for me.

$('#datepicker').val('');

where $('#datepicker') is the id of the input element.

Answer 9

I know it's a bit too late, but here's a simple peace of code that did it for me:

$('#datepicker-input').val('').datepicker("refresh");

A modified version of Leniel Macaferi's solution to account for the backspace key being a "page back" shortcut in IE8 when a text field does not have focus (which appears to be the case when datepicker is open).

It also uses val() to clear the field since _clearDate(this) did not work for me.

$("#clearDates").datepicker().keyup(function (e) {
    // allow delete key (46) to clear the field
    if (e.keyCode == 46)
        $(this).val("");

    // backspace key (8) causes 'page back' in IE8 when text field
    // does not have focus, Bad IE!!
    if (e.keyCode == 8)
        e.stopPropagation();
});

My datepicker initialization looks like:

    dateOptions = {
                changeYear: true,
                changeMonth: true,
                dateFormat: 'dd/mm/yy',
                showButtonPanel: true,
                closeText: 'Clear',
            };

So, the default 'Done' button will have 'Clear' text.

Now, inside datepicker.js find internal function '_attachHandlers' It looks like:

 _attachHandlers: function (inst) {
            var stepMonths = this._get(inst, "stepMonths"),
                id = "#" + inst.id.replace(/\\\\/g, "\\");
            inst.dpDiv.find("[data-handler]").map(function () {
                var handler = {
                    prev: function () {...},
                    next: function () {...},
                    hide: function () {
                        $.datepicker._hideDatepicker();
                    },
                    today: function () {...}
                    ... 

And change hide function to look like:

                   ...
                   hide: function () {
                        $.datepicker._clearDate(id);
                        $.datepicker._hideDatepicker();
                    },
                    ...

Answer 12

I use this code to clear the field and all shenannigans. I Needed an empty field for my use case

jQuery.datepicker._clearDate(window.firstDay);
window.firstDay.datepicker('setDate',null);
window.firstDay[0].value = '';

For some reason .val('') wouldn't work for me. But bypassing jQuery did it. In my opinion its a flaw that there is no .datepicker('clear') option.

Answer 13

My way to solve this problem

Change var 'controls' on ui.js

controls = (!inst.inline ? "<button type='button' class='ui-datepicker-close ui-state-default ui-priority-primary ui-corner-all' data-handler='hide' data-event='click'>" +
        this._get(inst, "closeText") + "</button>" + "<button type='button' class='ui-datepicker-close ui-datepicker-clear ui-state-default ui-priority-primary ui-corner-all' data-handler='hide' data-event='click'>" +
        this._get(inst, "clearText") + "</button>" : "");

Then add a clearText var

    this.regional[""] = { // Default regional settings
    closeText: "Done", // Display text for close link
    clearText: "Clear", // Display text for close link
    prevText: "Prev", // Display text for previous month link

And before show function

$(".i_date").datepicker
(
    {
        beforeShow: function (input, inst)
        {
            setTimeout
            (
                function () 
                { 
                    $('.ui-datepicker-clear').bind('click', function() { $(input).val(''); });
                }, 
                0
            );
        }
    }
);

Answer 14

$("#datepicker").datepicker({            
        showButtonPanel: true,
        closeText: 'Clear', 
        onClose: function () {
            var event = arguments.callee.caller.caller.arguments[0];                
            if ($(event.delegateTarget).hasClass('ui-datepicker-close')) {
                $(this).val('');
            }
        }
    });

Answer 15

In Firefox it does job for me in form (programmatically), where datepicker control is disabled by default:

$("#txtDat2").prop('disabled', false); //temporary enable controls<br>
$("#txtDat2").val("YYYY-MM-DD"); //reset date to dd.mm.yyyyy
$("#txtDat2").prop('disabled', true); //back to default state
