DatePicker date is not updated when value of underlying input field has been set programically

[Ondřej Kaláb]

Hi,

I am updating value of the underlying input field in some back events (form reset to default values), but the selected date in DatePicker when opened remains the previous one before input value reset.

Yes, I can make the DatePicker to update explicitly by $('#my-datepicker').datepicker('update'), but - is there a reason why DatePicker does not update itself on value change? 

Thanks.

I already know, it's standard in DOM that the change event is invoked bz user.

So I use - reluctantly - this workaround:

// Workaround:

// DatePicker doesn't know about programmic change of input's value.

// - jQuery docs (http://api.jquery.com/change/): "Note: Changing the value of an input element using JavaScript, using .val() for example, won't fire the event."

// - DOM Level 2 Event Specification (https://www.w3.org/TR/2000/REC-DOM-Level-2-Events-20001113/events.html): "The change event occurs when a control loses the input focus and its value has been modified since gaining focus."

// - here the problem in some forum: https://stackoverflow.com/questions/2247386/jquery-textbox-valxxxx-not-causing-change-to-fire

Meteor.defer(function() {

$('#my-datepicker').datepicker('update');

});
