I have the following code, when I click on the Picker I want to see the date 01/01/2018 selected in the calendar.
I need the calendar to select the date that contains the value of the imput.
$var_date = '01/01/2018';
<input type="text" name="date" name="date" class="datepicker" value="<?php echo $var_date; ?>">
<label for="first_name">Date</label>
This can be done with the help of instance.setDate(new Date()).
<input type="text" class="datepicker">
<script>
document.addEventListener('DOMContentLoaded', function () {
var elems = document.querySelector('.datepicker');
var instance = M.Datepicker.init(elems);
// instance.open(); This will open your datepicker on its own when page is loaded completely
instance.setDate(new Date(2018, 2, 8));
});
</script>
Note- new Date(year, monthIndex [, day [, hours [, minutes [, seconds [, milliseconds]]]]]);
The argument monthIndex is 0-based. This means that January = 0 and December = 11

I currently have a datetime field in my vue application. I want to split it up, but that would mean having to split it up in my database as well, which I am not interested in. I still want to keep the datetime column in my database table.
So my idea was to make it like 3 seperate fields: datetime, date and time. When a user has entered a date and time, these can be merged into the datetime field.
In Python you would do something like: datetime.datetime.combine( date, time )
Is there are similar method in Vue, or is there a better way of getting around this?
<b-form-row>
<b-col lg="6">
<b-form-group :label="$t('check in time')">
<time-picker v-model="guest.checkInDateTime" />
</b-form-group>
</b-col>
</b-form-row>
<b-form-row>
<b-col lg="6">
<b-form-group :label="$t('check in date')">
<date-picker v-model="guest.checkInDateTime" />
</b-form-group>
</b-col>
</b-form-row>
<b-form-row>
<b-col lg="6">
<b-form-group :label="$t('check in time and date')">
<date-time-picker v-model="guest.checkInDateTime"
:format="format"
:show-second="false"
type="datetime"/>
</b-form-group>
</b-col>
</b-form-row>
Working with dates in Javascript can be nuanced. In Javascript, assuming you have both a date value and a time value, you can easily combine these into a date string used by an html date picker like this:
const date = '2022-08-10' // string returned from date input
const time = '15:00:00' // string returned form time input
const checkInDateTime = date + 'T' + time // ISO String
If you're starting with a Date and you want to break it into a date value and a time value, it's almost easier using string manipulations than working with the Date obj, unless you're using a helper library like dayjs.
Examples:
// Assuming we have a date in ISO String format YYYY-MM-DDTHH:mm:ss
const dateFromString = dateValueFromDB.split('T')[0]
const timeFromString = dateValueFromDB.split('T')[1]
// using Date obj
const d = new Date(dateValueFromDB);
const dateFromObj = `${d.getFullYear()}-${('' + (d.getMonth() + 1)).padStart(2, '0')}-${('' + date.getDate()).padStart(2, '0')}`
const timeFromObj = `${d.getHours()}:${('' + d.getMinutes()).padStart(2,'0')}:${('' + d.getSeconds()).padStart(2,'0')}`
// using dayjs library
const dateFromDayjs = dayjs(dateValueFromDB).format('YYYY-MM-DD')
const timeFromDayjs = dayjs(dateValueFromDB).format('HH:mm:ss')
Now to answer your original question. Once we know how we're getting the correct values, in Vue.js, we can easily get and set these date values using a computed property and a custom setter.
<script>
export default {
data() {
return {
guest: {
checkInDateTime: '2022-09-10 15:00:00' // timestamp returned from database
}
}
},
computed: {
time: {
get() {
return dayjs( this.guest.checkInDateTime ).format('HH:mm:ss')
},
set(val) {
this.guest.checkInDateTime = this.date + 'T' + val
}
},
date: {
get() {
return dayjs(this.guest.checkInDateTime).format('YYYY-MM-DD')
},
set(val) {
this.guest.checkInDateTime = val + 'T' + this.time
}
}
}
}
</script>
Here's the html:
<template>
<div class="datetime-pickers">
<p>date: <input type="date" v-model="date" /></p>
<p>time: <input type="time" v-model="time" /></p>
<p>checkInDateTime: <input type="datetime-local" v-model="guest.checkInDateTime" /></p>
</div>
</template>
When any of the three values are set, the other two are updated accordingly. Here's a CodePen showing this in action:
https://codepen.io/ryanhightower/pen/ExLPobY?editors=1010
I have an HTML5 date input element like this:
<input type="date" />
if you choose a date in this input a string will be the value, for example:
"2018-12-31"
In my model I want the date to be presented as the following string:
"2018-12-31T00:00:00.000Z" and not the simplified string.
How do I make sure that the date in my model keeps the correct format? I tried using a computed but since I am in a loop this time I cannot use them.
{{eventDate.date}}
<b-form-input
v-bind:value="eventDate.date"
v-on:input="eventDate.date = $event.target.value"
v-bind:id="'event-day-date-' + index"
size="sm"
type="date"
placeholder="2018-12-31"
>
</b-form-input>
As you can see here the eventDate.date is a long string but the input needs the format YYYY-MM-DD. I need to convert it to and from this format some way.
You could use a filter:
filter: {
dateToString(date) {
return date.toString().substr(0,10)
}
}
and then update your template
:value="eventDate.date | dateToString"
This is what I ended up using:
<input
v-validate="'required'"
v-bind:name="'eventdate-' + index"
v-bind:value="eventDate.date | dateToString"
v-on:input="eventDate.date = $event.target.value + 'T00:00:00.000Z'"
v-bind:id="'event-day-date-' + index"
class="form-control form-control-sm"
type="date"
placeholder="2018-12-31"
/>
I receive from a WebAPI a JSON object that has this property:
"BirthDate": "2018-02-14T15:24:17.8177428-03:00",
the HTML:
<input type="date" v-model="BirthDate" />
I bind that object using VueJS, but
VueJS give this message in the console:
The specified value "2018-02-14T15:24:17.8177428-03:00" does not conform to the required format, "yyyy-MM-dd".
On this case the only relevant part is 2018-02-14, I can discard the other information.
I tried to create a Two Way filter to convert that Date Time to the required format but did not have success. See VueJS two way filter
How can I convert and bind that Date/Time format to the required Date Format of the HTML date input ?
Considering myDate is your property, you can use:
<input type="date" :value="myDate && myDate.toISOString().split('T')[0]"
#input="myDate = $event.target.valueAsDate">
Since v-model is only syntactic sugar to :value and #input, you can use them instead. In this case, we used and changed them a little (to format the String that is the output of the date input to a Date object and vice-versa).
Check demo and caveats below.
new Vue({
el: '#app',
data: {
message: 'Hello Vue.js!',
myDate: new Date('2011-04-11T10:20:30Z')
},
methods: {
setMyDateToToday() {
this.myDate = new Date();
},
addADayToMyDate() {
if (this.myDate) // as myDate can be null
// you have to set the this.myDate again, so vue can detect it changed
// this is not a caveat of this specific solution, but of any binding of dates
this.myDate = new Date(this.myDate.setDate(this.myDate.getDate() + 1));
},
}
});
// Notes:
// We use `myDate && myDate.toISOString().split('T')[0]` instead
// of just `myDate.toISOString().split('T')[0]` because `myDate` can be null.
// the date to string conversion myDate.toISOString().split('T')[0] may
// have timezone caveats. See: https://stackoverflow.com/a/29774197/1850609
<script src="https://unpkg.com/vue"></script>
<div id="app">
<p>{{ message }}</p>
<input type="date" :value="myDate && myDate.toISOString().split('T')[0]"
#input="myDate = $event.target.valueAsDate">
<p>

myDate: {{ myDate }}</code>
</p>
<button #click="setMyDateToToday">Set date one to today</button>
<button #click="addADayToMyDate">Add a day to my date</button>
</div>
i think this not related to vueJs , the input type="date" expected a date in YYYY-MM-DD format, or empty
see here : https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/date,
it would be better if you split date object as date and time field
Correction to #acdcjunior in that this shouldn't be off by one day
new Vue({
el: '#app',
data: {
message: 'Hello Vue.js!',
myDate: new Date('2011-04-11T10:20:30Z')
},
methods: {
setMyDateToToday() {
this.myDate = new Date();
},
addADayToMyDate() {
if (this.myDate) // as myDate can be null
// you have to set the this.myDate again, so vue can detect it changed
// this is not a caveat of this specific solution, but of any binding of dates
this.myDate = new Date(this.myDate.setDate(this.myDate.getDate() + 1));
},
getDateClean(currDate) {
// need to convert to UTC to get working input filter
console.log(currDate);
let month = currDate.getUTCMonth() + 1;
if (month < 10) month = "0" + month;
let day = currDate.getUTCDate();
if (day < 10) day = "0" + day;
const dateStr =
currDate.getUTCFullYear() + "-" + month + "-" + day + "T00:00:00";
console.log(dateStr);
const d = new Date(dateStr);
console.log(d);
return d;
}
}
});

I'm in the process of updating an old booking systems views and I am presently stuck on a solution for updating the calendar widget. As the site is responsive I have opted for the bootstrap datepicker supplied by eternicode https://github.com/eternicode/bootstrap-datepicker.
OK here the issue. I have an old Datepicker that splits the checkin & checkout dates into 3 parts and then formats the date for PHP (n = Month no leading zero)) (j = Day no leading zero) & (Y = Year 4 digit numeric).
// Initiate Params
$checkInDate = mktime(0,0,0,date("n"),date("j") + 1,date("Y"));
$checkOutDate = mktime(0,0,0,date("n"),date("j") + 3,date("Y"));
//CheckInDate
if (!isset($daysI)){
$daysI = date("j",$checkInDate);
}
if (!isset($monthsI)){
$monthsI = date("n",$checkInDate);
}
if (!isset($yearI)){
$yearI = date("Y",$checkInDate);
}
//CheckOutDate
if (!isset($daysS)){
$daysS = date("j",$checkOutDate);
}
if (!isset($monthsS)){
$monthsS = date("n",$checkOutDate);
}
if (!isset($yearS)){
$yearS = date("Y",$checkOutDate);
}
The input boxes markup is as below.
<input type='text' id='fulldate' name='fulldate'>
<label>Enter Day of Arrival (in the format DD) </label>
<input type="text" name="daysI" id="daysI" size="6" maxlength="6" />
<label>Enter Month of Arrival (in the format MM) </label>
<input type="text" name="monthsI" id="monthsI" size="6" maxlength="6" />
<label>Enter Year of Arrival (in the format YYYY) </label>
<input type="text" name="yearI" id="yearI" size="6" maxlength="6" />
Here's where I'm having the problem. The following function works with jQuery UI:
$('#fulldate').datepicker({
showAnim: 'fadeIn',
dateFormat: 'd/m/yy',
onSelect: function(dateText, inst) {
var pieces = dateText.split('/');
$('#daysI').val(pieces[0]);
$('#daysI').val(pieces[1]);
$('#daysI').val(pieces[2]);
}
});
However I cannot get a similar solution to work with the bootstrap-datepicker which I am using as a replacement for jQuery UI ie:
$('#fulldate').datepicker({
format: "d/m/yyyy",
todayBtn: "linked",
todayHighlight: true
onSelect: function(dateText, inst) {
var pieces = dateText.split('/');
$('#daysI').val(pieces[0]);
$('#monthsI').val(pieces[1]);
$('#yearI').val(pieces[2]);
}
});
Thank in advance for any solution..
The documentation gives an example of how to capture the date changed event: bootstrap-datepicker Docs - Change Date Event
Something like this should be in the right direction (untested):
$('#fulldate').datepicker()
.on('changeDate', function(ev){
var newDate = new Date(ev.date);
$('#daysI').val(newDate.getDate());
$('#monthsI').val(newDate.getMonth());
$('#yearI').val(newDate.getFullYear());
});
I have a dropdown list with dates, the values are as such:
<select name="DayDate" id="DayDate" data-val-date="The field DayDate must be a date." data-val="true" style="display: inline-block;" class="input-validation-error">
<option value="07/11/2013">donderdag 11 juli 2013</option>
<option value="07/10/2013">woensdag 10 juli 2013</option>
<option value="07/09/2013">dinsdag 9 juli 2013</option>
</select>
#Html.DropDownListFor(m => m.DayDate, Model.Days.Select(r => new SelectListItem
{
Text = r.Date.Value.ToString("D"),
Value = r.Date.Value.ToString("MM/dd/yyyy", CultureInfo.InvariantCulture)
}))
But when I submit I get as a date 7th of November, 7th of October or 7th of September!
The Thread culture is set to NL-nl and this has to remain this way.
So I thought of removing CultureInfo.InvariantCulture but then the model won't accept the date input data-val will be false, with this error: The field DayDate must be a date.
The following is set in the web.config
<globalization culture="nl-NL" uiCulture="nl-NL" />
How can I get the correct dates passed on?
Solved it by adding this piece of Javascript:
$.validator.methods.date = function (value, element) {
return true;
};
