I have the following function that is using a promise to return data from asynchronous ajax call:
$("#mySelect").on('change', function() {
var mySelectValue = $('#mySelect').val();
var promise = getAvailableDates(mySelectValue);
promise.done( function(data) { // tested and returning data
var array = data;
$('#a_date').datepicker({ // this function not working
dateFormat: "yy-mm-dd",
beforeShowDay: function (date) {
var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
return [array.indexOf(string) >= 0 ]
}
});
});
});
Why the $('#a_date').datepicker() function doesn't work inside another function?
It doesn't respond to my dateFormat and beforeShowDay settings based on data returned from my Ajax call.
How can I adjust Datepicker settings from inside a returned promise?
You have to destroy the first datetimepicker object created before reinitialize it, by the following statement:
$("#datepicker").datepicker("destroy");
see follow:
$( function() {
$( "#datepicker" ).datepicker({
dateFormat: "yy-mm-dd"
});
$("#btn1").click(function(){
$("#datepicker").datepicker("destroy");
$("#datepicker").datepicker({
dateFormat: "dd/mm/yy"
});
console.log("Format changed, try to select a new date");
});
} );<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
