A jQuery datepicker is wrappped in a Vue component. The component emits an update message used to update the app model.
The app has two datepicker input fields:
startDate
adjustmentDate
When startDate is modified, adjustmentDate is to be updated to the next first or fifteenth of the month. However, the adjustmentDate datepicker component is not being notified of the update.
Expected behaviour:
startDate datepicker onSelect triggers the Vue component emit which is captured by Vue method updateStartDate
method updateStartDate sets model property adjustmentDate
It was hoped this would trigger the adjustmentDate component update since the adjustmentDate model attribute is bound to the datepicker componentDate property which has a watch.
But changing the model doesn't have the affect of notifying the component.
Any suggestions how to do this properly and show the newly calculated adjustmentDate when the startDate is changed?

You need to remove the v-once directive from your adjustment date component as it prevents re-rendering when the data changes.
Additionally, you can simply put _calculateAdjustmentDate into a computed property, see Computed Properties.
See your updated example here: https://codepen.io/anon/pen/VQYarZ
There are some other issues with your code, I suggest you look into the Vue guide, especially at Method Event Handlers and Computed Properties as well as into Reactivity in Depth.
Also, _calculateAdjustmentDate does not really do what you describe, so you might look into this as well. You might consider Moment.js

I am trying to create a chrome extension but having problems with DOMContentLoaded as it is not firing.
Note: my code was taken from a different website.
Basically, I have create an HTML file with a button:
<head>
<title>GTmetrix Analyzer</title>
<script src="popup.js"></script>
</head>
<body>
<h1>GTmetrix Analyzer</h1>
<button id="checkPage">Check this page
now!</button>
</body>
And this is the JS file (popup.js):
document.addEventListener
('DOMContentLoaded',
function() {
console.log("f")
var checkPageButton =
document.getElementById('checkPage');
checkPageButton.addEventListener('click',
function() {
chrome.tabs.getSelected(null,
function(tab) {
d = document;
var f = d.createElement('form');
f.action = 'http://gtmetrix.com/analyze.html?bm';
f.method = 'post';
var i = d.createElement('input');
i.type = 'hidden';
i.name = 'url';
i.value = tab.url;
f.appendChild(i);
d.body.appendChild(f);
f.submit();
});
}, false);
}, false);
I added the console.log event in order to check if the event is executed, so this is how I verified that it isn't working.
I also added run_at": "document_start
but then I got
Uncaught TypeError: Cannot read property 'addEventListener' of null
For the "click" event, so I guess that the event was triggered before the button was created.
Help, please!
I need to show a datepicker allowing customer to choose multiple dates based on below criteria and also based on business logic that number of Orders can delivery per day.
Show T + 5 days only where T is current date and customer can choose only 5dates in datepicker for delivery. Other dates will be de activated
No Sundays
There will be threshold limit for order delivery. If for example no of orders on specific date met the threshold limit, then that date should be disabled from choosing and show next date for customer to choose for delivery.
$(document).ready( function() {
var threshold_orderlimit = 100; // limit for orders to accept
var tdays = 5; // show today + 5 days
var noOfOrdersPlaced = 40; // current order count
if(noOfOrdersPlaced >= threshold) {
tdays = tdays +1; // next 5 days
}
$("#date").datepicker( {
minDate: +tdays,
maxDate: '+5D', // show only 5 days
beforeShowDay: function(date) { // No sundays
var day = date.getDay();
return [(day != 0), ''];
}
});
});
Can some one help me to check if it is achievable in Jquery Date Picker
In case of using the Jquery Datepicker, its not possible to select multiple dates. Need to add a plugin jQuery MultiDatePicker.
var date = new Date();
var threshold_reached_dates = [date.setDate(15), date.setDate(29),date.setDate(18)];
var today = new Date();
var maximumdays_limit = 5;
var pickable_range = 6;
$("#datepicker").multiDatesPicker({
minDate:today,
beforeShowDay : function(date){ return [date.getDay()!=0,'']},
maxPicks : maximumdays_limit,
pickableRange : pickable_range,
adjustRangeToDisabled: true,
addDisabledDates : threshold_reached_dates
});
function getSelectedDates()
{
console.log($("#datepicker").multiDatesPicker("getDates"))
}

I need to use a date picker to work without internet.
I have changed my source links from https links to downloaded files in my local. But then Date picker stops working.
Can someone please let me know how to overcome this issue?
ideal source links :
<link href = "https://code.jquery.com/ui/1.10.4/themes/ui-lightness/jquery-ui.css" rel = "stylesheet">
<script src = "https://code.jquery.com/jquery-1.10.2.js"></script>
<script src = "https://code.jquery.com/ui/1.10.4/jquery-ui.js"></script>
Changed to locally downloaded files
<script src = "jquery-ui.js"></script>
<script src = "jquery-1.10.2.js"></script>
<script src = "jquery-ui.css"></script>
I shall be good if I can assure that even if https links used, it will work fine for my date pickers when internet is not there. Might be through some caching.
Updating my Question with datepickers code:
<span style="float: left;margin-left:2em"> <b>Date Range: </b>
<input type="text" id="datepicker" > <b>to </b>
<input type="text" id="datepicker2"> </span><div id = "Alert" style="float:left;margin-left:2em"> Please select a valid Date Range!</div>
.............................................
var startDate;
var endDate;
var start;
var end;
$(function() {
$("#datepicker").datepicker({
onSelect: function() {
startDate = $(this).datepicker('getDate');
start = formatDate(startDate);
if( start!=null && end!=null && end>=start)
{document.getElementById('Alert').style.visibility = 'hidden';
document.getElementById('canvas-holder').style.visibility = 'visible';
initial(start, end);
}
else {
document.getElementById('Alert').style.visibility = 'visible'; //Will show
document.getElementById('canvas-holder').style.visibility = 'hidden';
}
}
});
$("#datepicker2").datepicker({
onSelect: function() {
endDate = $(this).datepicker('getDate');
end = formatDate(endDate);
alert('skn here s' + startDate);
alert('skn here e' + endDate);
if( start!=null && end!=null && end>=start)
{document.getElementById('Alert').style.visibility = 'hidden';
document.getElementById('canvas-holder').style.visibility = 'visible';
initial(start, end);
}
else {
document.getElementById('Alert').style.visibility = 'visible'; //Will show
document.getElementById('canvas-holder').style.visibility = 'hidden';
}
}
});
});
Please find below error I get in browser console.
Uncaught TypeError: $(...).datepicker is not a function

I have incorporated changes as suggested. In that case date picker shows but not as expected.

you need to load jquery before jquery-ui.js
I have two input text box startdate and enddate
<input type="text" id="startdate"/>
<input type="text" id="enddate"/>
I need two simple things
On click of startdate and selection of start date, need to update
end date with +7 days.
Format needed is mm/dd/yyyy
So if any one click startdate with 01/01/2015 i.e 1st January 2015 , than end date should automatically set with 01/08/2015
On selection of startdate, I need to get enddate open automatically.
The datepicker Library I had used is ALLOYUI datepicker version 3.0
http://alloyui.com/examples/datepicker/
Can anyone please write down code please.
Guys
<script>
var datefrom;
YUI().use(
'aui-datepicker',
function(Y) {
datefrom = new Y.DatePicker(
{
trigger: '#dpfrom',
popover: {
zIndex: 1
},
calendar: {
//maximumDate : new Date(today.getFullYear(),today.getMonth()+1,today.getDate()),
minimumDate : new Date(),
},
on: {
selectionChange: function(event) {
}
}
}
);
}
);
//console.log(james);
</script>
I found the may to set minimum and maximum date but still i donot have the way to set end date +7 days to current date.
Please find similar and working one for me. Please customize it if you need anything.
<input class="form-control" type="text" id="selecteddate" placeholder="Day, Mon dd, yyyy"></input>
YUI().use(
'aui-datepicker',
function(Y) {
var datepicker = new Y.DatePicker(
{
trigger: 'input',
popover: {
zIndex: 1
},
after: {
selectionChange: function(event) {
event.preventDefault();
Y.log(datepicker.getSelectedDates());
var myDate=Y.DataType.Date.addDays(new Date(datepicker.getSelectedDates()),+6);
if (myDate.isValid()) {
$("#selecteddate").val(myDate);
}
}
}
}
);
}
);
Date.prototype.isValid = function () {
// An invalid date object returns NaN for getTime() and NaN is the only
// object not strictly equal to itself.
return this.getTime() === this.getTime();
};
I'm using two DateTimePickers http://tarruda.github.io/bootstrap-datetimepicker/ in my code: one for choosing a date (pickTime disabled) and the other for the time (pickDate disabled).
I've managed to set a startDate for the date, but how can I set a startTime and an endTime, in such a way that the any time before that startTime is disabled?
<script type="text/javascript">
$(function() {
$('#datetimepicker4').datetimepicker({
pickTime: false,
startDate: new Date(2013,9,8)
});
});
</script>
<script type="text/javascript">
$(function() {
$('#datetimepicker3').datetimepicker({
pickDate: false,
startTime: ???
});
});
</script>
This question is OLD but thought it might help some one.
JS
$('.time').datetimepicker({
format: 'LT'
}).on("dp.change",function(e){
var date = e.date;//e.date is a moment object
var target = $(e.target).attr('name');
console.log(date.format("HH:mm:ss"))//get time by using format
})
e.date is a moment object thus time can derived by using format("HH:mm:ss")
