Simulating enter key after selecting date (jquery)

I've got a form field using the jQuery datepicker function on a Wordpress website using a product customizer plugin. The form field by default was never intended to be a date picker, I added that later. While I can get the date picker working fine with the field itself, the only way it'll actually show on the product is if you press enter in the field after selecting the date. I'd like this to happen automatically so it appears after the user selects a date, or when the datepicker box loses focus. I've attempted to simulate the enter key being pressed using this but it didn't do anything (console log worked though):
jQuery(function () {
var e = jQuery.Event( "keydown", { keyCode: 13 } );
jQuery("#ui-datepicker-div").focusout(function() {
jQuery("#date-of-birth-field").focus();
jQuery("#date-of-birth-field").trigger( e );
console.log("test");
});
#ut-datepicker-div is the datpicker calendar element, while #date-of-birth-field is the input ID where the date appears.
Any other way of achieving this? I also tried the 'load' function but that didn't work either.

Try this in your definition:
jQuery(function($) {
$("#date-of-birth-field, #date-of-death-field, #companioin-2-date-of-birth-field, #companioin-2-date-of-death-field").datepicker({
changeMonth: true,
changeYear: true,
yearRange: "c-100:c+0",
showButtonPanel: true,
dateFormat: 'M dd yy',
onSelect: function(dt, obj) {
$(this).trigger($.Event("keypress", {
which: 13
}));
}
});
$("#component-5ed524ac8d83c, #component-5ed671ac50881").click(function() {
$(this).addClass("maxSize");
});
});
When a Date is selected, it should trigger an Enter keypress.

Bootstrap datepicker close function

I am trying to make function call on bootstrap datepicker when user clicks outside of calendar.
When user selects date datepicker closes automatically, same when user clicks outside of the datepicker div, it closes itself.
So my question is how can I understand when its closed? I know there is an event called onClose but it only works when page loads
fiddle

Use the .on("hide"... event.
From the docs:
$('.datepicker').datepicker()
.on(picker_event, function(e) {
// `e` here contains the extra attributes
});
For your example... picker_event will be hide.
Something like:
var checkin = $('#date-from').datepicker({
format: 'dd/mm/yyyy',
startDate: '+1d',
weekStart: 1,
beforeShowDay: function(date) {
return date.valueOf() >= now.valueOf();
},
autoclose: true
}).on('changeDate', function(ev) {
alert("changed");
}).on('hide', function(ev) { // <-----------
alert("hide");
});
Updated fiddle
bootstrap-datepicker events
bootstrap-datepicker hide event

As per the documentation here: https://bootstrap-datepicker.readthedocs.io/en/latest/events.html#hide
$('.datepicker').datepicker()
.on('hide', function(e) {
// `e` here contains the extra attributes
});
Or
$('.datepicker').datepicker()
.on('hide', myFunction);
And then create myFunction
function myFunction(e) {
// whatever you want :)
}
Here is your example with little modify https://jsfiddle.net/mr3dxj5p/6/ here you can see I just change changeDate to hide to fire alert message

bootstrap datepicker change date event doesnt fire up when manually editing dates or clearing date

<script type="text/javascript">
// When the document is ready
$(document).ready(function () {
$('.datepicker').datepicker({
format: "yyyy-mm-dd",
}).on('changeDate', function(ev){
// do what you want here
$(this).datepicker('hide');
}).on('changeDate', function(ev){
if ($('#startdate').val() != '' && $('#enddate').val() != ''){
$('#period').text(diffInDays() + ' d.');
} else {
$('#period').text("-");
}
});
});
</script>
So here's what my datepicker looks like. So basically when I change date by clicking mouse it works good, however when I manually change date with keyboard or manually clear the date change date event doesn't get called. Is this a bug or am I doing something wrong here ?

You have to use the change event on the input itself if you want to respond to manual input, because the changeDate event is only for when the date is changed using the datepicker.
Try something like this:
$(document).ready(function() {
$('.datepicker').datepicker({
format: "yyyy-mm-dd",
})
//Listen for the change even on the input
.change(dateChanged)
.on('changeDate', dateChanged);
});
function dateChanged(ev) {
$(this).datepicker('hide');
if ($('#startdate').val() != '' && $('#enddate').val() != '') {
$('#period').text(diffInDays() + ' d.');
} else {
$('#period').text("-");
}
}

changeDate has been renamed to change.dp so changedate was not working for me
$("#datetimepicker").datetimepicker().on('change.dp', function (e) {
FillDate(new Date());
});
also needed to change css class from datepicker to datepicker-input
<div id='datetimepicker' class='datepicker-input input-group controls'>
<input id='txtStartDate' class='form-control' placeholder='Select datepicker' data-rule-required='true' data-format='MM-DD-YYYY' type='text' />
<span class='input-group-addon'>
<span class='icon-calendar' data-time-icon='icon-time' data-date-icon='icon-calendar'></span>
</span>
</div>
Date formate also works in capitals like this data-format='MM-DD-YYYY'
it might be helpful for someone it gave me really hard time :)

The new version has changed.. for the latest version use the code below:
$('#UpToDate').datetimepicker({
format:'MMMM DD, YYYY',
maxDate:moment(),
defaultDate:moment()
}).on('dp.change',function(e){
console.log(e);
});

Try this:
$(".datepicker").on("dp.change", function(e) {
alert('hey');
});

I found a short solution for it.
No extra code is needed just trigger the changeDate event. E.g.
$('.datepicker').datepicker().trigger('changeDate');

Try with below code sample.it is working for me
var date_input_field = $('input[name="date"]');
date_input_field .datepicker({
dateFormat: '/dd/mm/yyyy',
container: container,
todayHighlight: true,
autoclose: true,
}).on('change', function(selected){
alert("startDate..."+selected.timeStamp);
});

This should make it work in both cases
function onDateChange() {
// Do something here
}
$('#dpd1').bind('changeDate', onDateChange);
$('#dpd1').bind('input', onDateChange);

Depending which date picker for Bootstrap you're using, this is a known bug currently with this one:
Code: https://github.com/uxsolutions/bootstrap-datepicker
(Docs: https://bootstrap-datepicker.readthedocs.io/en/latest/)
Here's a bug report:
https://github.com/uxsolutions/bootstrap-datepicker/issues/1957
If anyone has a solution/workaround for this one, would be great if you'd include it.

I have this version about datetimepicker https://tempusdominus.github.io/bootstrap-4/ and for any reason doesn`t work the change event with jquery but with JS vanilla it does
I figure out like this
document.getElementById('date').onchange = function(){ ...the jquery code...}
I hope work for you

I was using AngularJS and AngularStrap 2.3.7 and trying to catch the 'change' event by listening to a <form> element (not the input itself) and none of the answers here worked for me. I tried to do:
$(form).on('change change.dp dp.change changeDate' function () {...})
And nothing would fire. I ended up listening to the focus and blur events and setting a custom property before/after on the element itself:
// special hack to make bs-datepickers fire change events
// use timeout to make sure they all exist first
$timeout(function () {
$('input[bs-datepicker]').on('focus', function (e){
e.currentTarget.focusValue = e.currentTarget.value;
});
$('input[bs-datepicker]').on('blur', function (e){
if (e.currentTarget.focusValue !== e.currentTarget.value) {
var event = new Event('change', { bubbles: true });
e.currentTarget.dispatchEvent(event);
}
});
})
This basically manually checks the value before and after the focus and blur and dispatches a new 'change' event. The { bubbles: true } bit is what got the form to detect the change. If you have any datepicker elements inside of an ng-if you'll need to wrap the listeners in a $timeout to make sure the digest happens first so all of your datepicker elements exist.
Hope this helps someone!

jQuery .closest on $(event.target) disables other click events

I have a jQuery plugin project, actually if it helps it's in github and you can see the full code at https://github.com/jondmiles/bootstrap-datepaginator/tree/1.2.0.
So I have an click event handler, one of the first things it does is use jQuery .closest to look up the DOM and find the parent anchor tag that the user has clicked. This is necessary as icons sit in front of some anchors and I want consistency in the element I'm handling.
Here's the code in question, line 273 of /src/bootstrap-datepaginator.js in the project if you want it in context.
_clickedHandler: function (event) {
event.preventDefault();
var target = $(event.target).closest('a');
var classList = target.attr('class') ? target.attr('class').split(' ') : [];
if (classList.indexOf('dp-no-select') !== -1) {
// do nothing
}
else if (classList.indexOf('dp-nav-left') !== -1) {
this._navBack();
}
else if (classList.indexOf('dp-nav-right') !== -1) {
this._navForward();
}
else if (classList.indexOf('dp-item') !== -1) {
this._select(target.attr('data-moment'));
}
},
Now I also have a datepicker (https://github.com/eternicode/bootstrap-datepicker) which is attached to an icon element, added during the rendering process.
It looks like this, line 476 in the project
if (this.$calendar) {
this.$calendar
.datepicker({
autoclose: true,
forceParse: true,
startView: 0,
minView: 0,
todayHighlight: true,
startDate: this.options.startDate.date.toDate(),
endDate: this.options.endDate.date.toDate()
})
.datepicker('update', this.options.selectedDate.date.toDate())
.on('changeDate', $.proxy(this._calendarSelect, this));
}
When the user clicks on the calendar icon the datepicker should appear. It used to, up until a recent change but now nothing happens; no calendar.
I've tracked the issue down to the addition of the .closest() method which was a recent addition. So it appears calling the .closest() on the event target some how suppresses the datepicker, but I can't figure out why, or how to work around this.
So to recap, when it worked line 275 looked like this
var target = $(event.target);
Now it doesn't work, line 275 looks like this
var target = $(event.target).closest('a');
Any ideas?

Launch jQuery .datepicker from Another JS Function

I need to launch .datepicker only if the text entered into a field does not meet a set of criteria. But, I can not figure out how to launch .datepicker other than directly from a field getting focus or a button being presses.
What I'm trying to do...
The HTML
<input type="text" id="userDate" name="userDate" style="width: 100px;" onblur="checkDate(this.id);" />
The JS
function checkDate(theId)
{
var enteredValue = document.getElementById(theId).value;
var checkedValue = evaluateValue(enteredValue); // this checks to see if the text meets the criteria
if (checkedValue == null)
{
// this is where I want to call the .datepicker to have the calendar show up
$("#userDate").datepicker();
}
else
{
document.getElementById(theId).value = checkedValue;
}
}
I know, this would be easier if the calendar just came up when the text field gets focus. But, this is not the way the client wants it to work. They want to accept user input as long as it falls into their desired formats. If not, then they want the calendar and a default, forced format.
Thanks.

If you are using the datepicker in jQuery UI, you would show the datepicker like this:
$("#userDate").datepicker("show");
Edit:
Your code would probably have to look something like this:
$(function(){
$("#userDate").datepicker(); // <-- Create the datepicker on load
});
function checkDate(theId)
{
var enteredValue = document.getElementById(theId).value;
var checkedValue = evaluateValue(enteredValue); // this checks to see if the text meets the criteria
if (checkedValue == null)
{
// this is where I want to call the .datepicker to have the calendar show up
$("#userDate").datepicker("show"); // <-- Show datepicker when needed
}
else
{
document.getElementById(theId).value = checkedValue;
}
}

Okay, after many cans of Pepsi Max and even more hours of research, trial and error; this is what I've come up with... and it meets my needs.
$(document).ready( function()
{
$("#userDate").blur(function()
{
var convertResults = convertMyDate('userDate'); // call to my code that checks the date for accepted formats
if (convertResults == null)
{
$("#userDate").datepicker({
changeMonth: true,
changeYear: true
});
$("#userDate").datepicker("show");
}
else
{
document.getElementById('userDate').value = convertResults.toString('MM/dd/yyyy');
}
});
});
The only problem now is that the client's form has 14 date fields. So... copy this 13 more times in my code!? I just don't have the time right now to figure out a way to roll all this into a single function that will initiate all of them in a loop...
Any suggestions on that would be appreciated.
