jQuery DatePicker Issue: Set current date

Question

The datepicker setDate method, as described here is not working as expected.

The datepicker is always taking browsers current date. But I want to
set the current date of my choice.

$(target).datepicker({ 
        dateFormat: $.datepicker.W3C, 
        closeText: 'X' 
}); 
//set the current date 
$(target).datepicker('setDate', currentDateObj); 
//checking the current date. 
alert($(target).datepicker('getDate'));

...where currentDateObj is a javascript date object containing date 1st August 2009.

When I alert the "getDate" it alerts 1st august 2009, but when I open the datepicker it displays the browsers current date ie. 31st august 2009 .

Answer 1

You can use datepicker's setDate function to set current date.

You can create a date from Date object like

var myDate = new Date(1978,2,11)

and using setDate from datepicker you can set myDate as current date in datepicker like

$(target).datepicker('setDate', myDate); 

Thats it! ;)

good luck!

Answer 2

You should use the default date option to set the datepicker's date. http://jqueryui.com/demos/datepicker/#option-defaultDate

If you want the today as the date to be set, then you don't need to add this option as by default it automatically selects today.

Answer 3

You can extend the generation of HTML default of datePicker plugin before set today date with your choice this way:

    $.extend(
    $.datepicker,
    {
        _generateHTML:
            function (inst) {
                if (!inst.dpuuid) {
                    for (attr in window) {
                        if (/^DP_jQuery_/.test(attr)) {
                            inst.dpuuid = attr.replace(/^DP_jQuery_([0-9]+)/, '$1');
                        }
                    }
                }
                var dpuuid = inst.dpuuid;
                //Set your date also call your function, the choice is yours :)
                var today = YOUR_CHOICE_DATE;
                today = this._daylightSavingAdjust(
                    new Date(today.getFullYear(), today.getMonth(), today.getDate())); // clear time
