I am trying to do some simple calculations, I need to take a date and add x-months to that date. After searching, I decided to use DateJS to account for edge dates.
I set up a form that allows the user to enter the date and amount of months. On a keyup function, it calculates the new date. The issue is it's not calculating correctly.
I can pass the date from the form to the JS and manually specify the months in JS and it calculates correctly. If I pass both the date and months from the form the calculation is off by a lot. Years in fact!
If I replace $("#monthincrease").val() with a hard coded number the calculation works fine. But not when using data from the form.
<div class="container">
<div class="jumbotron">
<h1>Future Date Calculator</h1>
<p>To calculate a future date, enter a start date and the amount of months to add.</p>
</div>
<div class="row">
<div class="col-lg-12">
<form class="form-inline" role="form">
<div class="form-group">
<label for="startdate">Start Date:</label>
<input type="date" class="form-control" id="startdate">
</div>
<div class="form-group">
<label for="monthincrease"> And Months To Add:</label>
<input type="number" class="form-control" id="monthincrease">
</div>
</form>
<p>Date: <span class="futuredate"></span></p>
<p>Month: <span class="month"></span></p>
</div>
</div>
<script type="text/javascript">
$("#monthincrease").on('keyup',function() {
var newDate = Date.parse( $("#startdate").val() ).addMonths( $("#monthincrease").val() );
$(".futuredate").html(newDate);
$(".month").html( $("#monthincrease").val() );
});
</script>
This is my updated code.
<div class="container">
<div class="jumbotron">
<h1>Future Date Calculator</h1>
<p>To calculate a future date, enter a start date and the amount of months to add.</p>
</div>
<div class="row">
<div class="col-lg-12">

<div class="form-group">
<label for="startdate">Start Date:</label>
<input type="date" class="form-control" id="startdate">
</div>
<div class="form-group">
<label for="monthincrease"> And Months To Add:</label>
<input type="number" class="form-control" id="monthincrease">
</div>
</form>
<p>Date: <span class="futuredate"></span></p>
</div>
</div>
<script type="text/javascript">
$( document ).ready(function() {
$("#monthincrease").on('keyup',function() {
var incMonths = $("#monthincrease").val();
var startDate = $("#startdate").val();
var newDate = new Date.parseExact( startDate, "yyyy-MM-dd" ).addMonths( incMonths );
$(".futuredate").html(newDate);
console.log(incMonths);
console.log(startDate);
console.log(newDate);
});
});
</script>
</div>
I change the var to var incMonths = Number( $("#monthincrease").val() ); which converted the form input into a number. Works now.
Try putting in your event code in document.ready block. Also for correct calculation use parseExact method of DateJS library and specify the format in which date will be entered in textbox. https://code.google.com/p/datejs/wiki/APIDocumentation
Updated:
$( document ).ready(function() {
$("#monthincrease").on('keyup',function() {
var incMonths = $("#monthincrease").val();
var startDate = $("#startdate").val();
var newDate = new Date.parseExact( startDate, "M/d/yyyy" ).addMonths( parseInt(incMonths ));
$(".futuredate").html(newDate);
});
});
I corrected the date format and used parseInt for months field. Try it now.

I have a php page.
There are two date fields on my page and 10 input fields showing various charges.
On selecting check-in and check-out date and clicking submit button, it calculates number of days. Im using moment js for that.
Once number of days are calculated, I want value of all text fields like rent and others to be multiplied by number of days and show the value in respective fields. This is my php page:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
From: <input id="fromDate" type='date' />
To: <input id="toDate" type='date' />
<button id="btn">Submit</button><hr />
<p id="result"></p>
<script>
$("#btn").on('click', function(e) {
var fromDate = $('#fromDate').val(),
toDate = $('#toDate').val(),
from, to, duration;
from = moment(fromDate, 'MM-DD-YYYY');
to = moment(toDate, 'MM-DD-YYYY');
/* using diff */
duration = to.diff(from, 'days')
/* show the result */
$('#result').text(duration + ' days');
});
</script>
Here is one of the fields whose value I want to be updated
<div class="form-group">
<div class="row">
<div class="control-label col-sm-4"><b>Room Rent :</b></div>
<div class="col-sm-4">
<input text="text" name="ipt_item_1" id="ipt_item_1"
value="1500">
<div class="col-sm-2"><input type="checkbox" name="chk_item_1"
class="chk-amount" data-target="ipt_item_1"></div>
</div>
</div>
</div>
I don't know how to do it.
Any suggestions would be appreciated.
Thanks
I am setting up a website that adds event start and end dates/times to a database. I would like to dynamically set minDate (for the end date/time) based on the input from the previous event start.
I am using https://www.jqueryscript.net/time-clock/Date-Time-Picker-Bootstrap-4.html for my date/time picker and bootstrap 4.
<div class="form-group row">
<label for="eventStart" class="col-3 col-form-label">Event start date and time</label>
<div class="col-5">
<div class="input-group date" id="datetimepicker1">
<input id="eventStart" name="eventStart" type="text" required="required" class="form-control here">
<div class="input-group-addon append"><i class="fa fa-calendar"></i>
</div>
</div>
</div>
<script type="text/javascript">
$(function () {
$('#datetimepicker1').datetimepicker({
format: 'DD/MM/YYYY HH:mm',
stepping: 15
});
});
</script>
</div>
<div class="form-group row">
<label for="eventEnd" class="col-3 col-form-label">Event end date and time</label>
<div class="col-5">
<div class="input-group date" id="datetimepicker2">
<input id="eventEnd" name="eventEnd" type="text" required="required" class="form-control here">
<div class="input-group-addon append"><i class="fa fa-calendar"></i></div>
</div>
</div>
<script type="text/javascript">
$(function () {
$('#datetimepicker2').datetimepicker({
format: 'DD/MM/YYYY HH:mm',
stepping: 15,
minDate: '2019/1/23 20:00'
});
});
</script>
</div>
I can set minDate manually (as above) but not sure how to take the value from the previous text input (datepicker1) with perhaps 'onblur'?
you can call the datetime api methods like this
$('#datetimepicker').data("DateTimePicker").minDate('2019/1/23')
and call the api dynamic
$('#datetimepicker1').on('change',function(){
var newdate=$(this).val();
if(newdate){
$('#datetimepicker2').data("DateTimePicker").minDate(newdate)
}
});
have a try
The answer to your question is clearly stated on the documentation https://www.jqueryscript.net/time-clock/Date-Time-Picker-Bootstrap-4.html
Basically, you can dynamically set minDate for the second datetimepicker by setting an event listener on the first datetimepicker that fires an event whenever user select the first datetime.
$('#datetimepicker1').datetimepicker(... your options ...).on( "dp.change", function(e) {
// Fired when the date is changed.
// Get the datetime value
console.log(e.target.value);
})
Then you can reset the minDate of second datetimepicker using this API function:
// Takes a minDate string, Date, moment, boolean:false parameter and disallows the user to select a moment that is before that moment. If a boolean:false value is passed the options.minDate parameter is cleared and there is no restriction to the miminum moment the user can select.
$('#datetimepicker2').data("DateTimePicker").minDate(minDate)
I would like to insert date-picker into my form, which shows me automatically today's date without choosing a date. The from below makes you choose the date, any one can help me please with that..
<div class="form-group">
<label class="container" for="name">Erän saapumispäivä :</label>
<div class="col-sm-5">
<input type="date" class="form-control" id="Entery_Date"
[(ngModel)]="addProduct.Entery_Date" name="Entery_Date" #Entery_Date="ngModel">
<div *ngIf="Entery_Date.errors && (Entery_Date.dirty || Entery_Date.touched)" class="alert alert-danger">
<div [hidden]="!Entery_Date.errors.required">
Erän saapumispäivä on pakollinen!
</div>
</div>
</div>
It is a good idea to use material Date Picker (https://material.angular.io/components/datepicker/overview)
It should meet all your requirements
Please take a look to the below example.
<input name="dateInput" type="date" ng-model="date"/>
Now, in your controller use the below code:
var d=new Date();
var year=d.getFullYear();
var month=d.getMonth()+1;
if (month<10){
month="0" + month;
};
var day=d.getDate();
$scope.date=year + "-" + month + "-" + day;
Hope this will work :)
I'm sure this is simple and it's my understanding of jquery/javascript that is holding me back - but I can't get this to work.
All I need to do - is - When a button on the screen is clicked, clear some of the input field on the form back to their original values.
This is working fine, for all fields except a datetimepicker field.
Here is the relevant bits of code, that defines the input field :
<div class='form-group' id='START_DATEFormGroup'>
<label for='START_DATE' class='col-sm-2 control-label' data-toggle='tooltip' data-placement='top' title=''>Start Date</label>
<div class='col-sm-8'>
<div class='input-group date form_date col-sm-3' data-date-format='dd M yyyy' data-link-field='START_DATE' data-link-format='yyyy-mm-dd'>
<input class='form-control' size='16' type='text' />
<input type='hidden' id='START_DATE' name='START_DATE' />
<span class='input-group-addon'>
<span class='glyphicon glyphicon-calendar'>
</span> // group-addon
</span> // calendar
</div> // form_date
</div> // col-sm-8
</div> // form-group
I am initializing datetimepicker as follows :
function enableDatepicker(){
$( document ).ready(function() {
$('.form_date').datetimepicker({
format: 'dd M yyyy',
minView: 2,
autoclose: 1,
})
});
}
To clear the input fields down I have :
function clearActionForm(){
// code here to clear the various input fields to null or their initial values.
// Need statements to clear the datetimepicker field to null.
}
So, can someone give me the line(s) of code I need to insert into clearActionForm() in order to clear the START_DATE field to null.
Thanks.
If you are using the eonasdan datetimepicker use the following:
// clears
$("#form_date").data("DateTimePicker").date(null);
// updates with date
$("#form_date").data("DateTimePicker").date(new Date());
// or update with string
var myCoolDate = "27 05 1975";
$("#form_date").data("DateTimePicker").date(myCoolDate);
// or update with a moment
var moment = moment().add(2, 'd');
$("#form_date").data("DateTimePicker").date(moment);
Below is a demo of using different types of changes.
$(function() {
$('#datetimepicker1').datetimepicker({
format: 'dd M YYYY',
});
});
$('#clear').click(function() {
$("#datetimepicker1").data("DateTimePicker").date(null);
})
$('#date').click(function() {
var sysdate = new Date();
$("#datetimepicker1").data("DateTimePicker").date(new Date());
})
$('#string').click(function() {
var myCoolDate = "27 05 1975";
$("#datetimepicker1").data("DateTimePicker").date(myCoolDate);
})
$('#moment').click(function() {
var now = moment().add(2, 'd');
$("#datetimepicker1").data("DateTimePicker").date(now);
})

Easy way to rest the selected date as well as highlighted date by below concept
$('#txtWQApprovalDate').datepicker('setDate', null).datepicker('fill');
Assuming that you are using the datetimepicker plugin from xdsoft.net/jqplugins/datetimepicker, one quick way to clear the datetimepicker's current value would be the following:
$('.form_date').val('');
As an alternative (this sets the value of the datetimepicker to the current time):
$('.form_date').datetimepicker({
value: (new Date()).toLocaleString()
});
This value does not not match the format of the datetimepicker, but will be converted to the correct format automatically when the datetimepicker is used.
If you are using the eonasdan datetimepicker use the following:
// clears
$j(".form_date").data("DateTimePicker").setDate(null);
// updates to now
$j(".form_date").data("DateTimePicker").setDate(new Date());
// or update to a given date
var myCoolDate = "05/27/1975";
$j(".form_date").data("DateTimePicker").setDate(myCoolDate);
I have a code of calender in java script. Its in working, want it to automaticaly select current date .its Possible.
Javascript code:
<script>
$(function() {
$( "#interview_on" ).datepicker();
});
</script>
Custom Form:
<form method="POST" action="/interviewvalue/" class="form-horizontal" id="userform" name="uform" enctype="multipart/form-data">{% csrf_token %}
<div class="control-group formSep">
<label for="u_fname" class="control-label">Interview On</label>
<div class="controls">
<input type="text" class="input-xlarge" name="interviewon" id="interview_on" readonly="true" />
</div>
</div>
<div class="control-group">
<div class="controls">
<button class="btn btn-gebo" type="submit" name="asubmit">Submit</button>
<input type="reset" name="reset" value="Cancel" class="btn btn-gebo" />
</div>
</div>
If you want the actual field to be filled with the current date just use the setDate after creating the datepicker. Like this
<script type="text/javascript">
$(function() {
$("#interview_on").datepicker();
$("#interview_on").datepicker('setDate', new Date());
});
</script>
In case you want to restrict the selectable dates to only today, Tobo's suggestion is correct, just do
<script type="text/javascript">
$(function() {
$("#interview_on").datepicker({minDate: 0, maxDate: 0});
$("#interview_on").datepicker('setDate', new Date());
});
</script>
You can restrict the selectable range of the Datepicker like this
$( "#datepicker" ).datepicker({
minDate: -10D, maxDate: "+10D"
});
which shows 10 days of the past and 10 days of the future.
