Could you explain the usecase for this?

IIUC, when using: showOn:'both' there is no way for a user to erase the value and specify no date with a blank entry.

But there might be a method I missed, in my case (1.6rc6) I switched to showOn:'button'

example usecase is clearing a date when input field is readonly (the reason for doing it readonly as here: http://dev.jqueryui.com/ticket/4079#comment:3)

Clear functionality is definitely needed. I spent half a day Googling and trying to find some workaround to clear the selected dates. Without this functionality there is no way I can reset the form, and I think this is a serious shortcoming.

Please add this functionality, as it seems a lot of people need it.

I would really like to see this feature added, too. I might have to switch to a different calendar that supports this.

I've seen some discussion that this feature isn't needed because the user can just clear the field - NOT TRUE. On most of the sites I've worked on that use a date picker the field is READ ONLY. Often times the server expects the date in a certain format so the user isn't allowed to just type in whatever they want - instead they are forced to use the date picker. So we need a clear option please. :-)

I think it is necessary to implement this option, given that the field is read only once you enter a date can not be erased, thanks

here is my solution, you can use done button as clear with the following hack

$(".datepicker").datepicker({

showButtonPanel: true, closeText: 'Clear',

});

$.datepicker._generateHTML_Old = $.datepicker._generateHTML; $.datepicker._generateHTML = function(inst) {

res = this._generateHTML_Old(inst); res = res.replace("_hideDatepicker()","_clearDate('#"+inst.id+"')"); return res;

}

I created a fork of jquery which supports the clear option. You have to enable the button bar and also add { showClearButton : true } to the options.

I sent a pull request to the jquery-ui maintainers; hopefully they will reconsider the removal of this feature and merge my pull request.

Using 2 DatePicker? that are tied together to define a date range. Clearing the text from either text input does not clear the date in the underlying DatePicker? object or the restrictions that are imposed by the previously selected date.
