I have these two calendar pickers that chooses the date for you, one for arrival and one of departed.
If the user chooses a day in departed calendar that is earlier than the one in arrival calendar, the calendar picker should be either disabled or when choosen - ignore it.
For example: arrival is 2017-03-08, choosen and read in the textbox and same for departed. If I try to pick 2017-03-07 for departed, it should not allow it and not be read in the textbox.
How is this possible with javascript/jquery?
My code:
var CalendarTwo;
function onPopupTxtArrivalDateChanged(sender) { //Function that reads arrival date
var txtArrival = $("#txtArrivalDate");
var date = new Date(sender.getSelectedDate());
var textDate = date.getFullYear() + "-" + (date.getMonth() <= 9 ? "0" + (date.getMonth() + 1)
: (date.getMonth() + 1)) + "-" + (date.getDate() <= 9 ? "0" + date.getDate() : date.getDate());
txtArrival.val(textDate);
onChange(sender, txtArrival, $("#txtDepartureDate")[0], CalendarTwo);
}
function onPopupTxtDepartureDateChanged(sender) { //Function that reads departed date
var txtDeparture = $("#txtDepartureDate");
var date = new Date(sender.getSelectedDate());
var textDate = date.getFullYear() + "-" + (date.getMonth() <= 9 ? "0" + (date.getMonth() + 1)
: (date.getMonth() + 1)) + "-" + (date.getDate() <= 9 ? "0" + date.getDate() : date.getDate());
CalendarTwo = sender;
txtDeparture.val(textDate);
}
function onChange(sender, txt, departed, calendarTwo) { //Function that checks that arrival date and departed is equal
var txtDate = $(txt).val();
var date = new Date(txtDate);
if (departed != undefined) {
CalendarTwo = calendarTwo;
var departedDate = new Date($(departed).val());
if (departedDate < date) {
calendarTwo.setSelectedDate(date);
departed.value = txtDate;
}
}
sender.SetSelectedDate(date);
}
I am trying to get the day 90 days after today. This is my code:
var today = new Date();
var threeMonthsFromToday = new Date(today.setDate(today.getDate() + 90));
When I print threeMonthsFromToday, I get the correct date: 2017-04-24T15:17:42.641Z. However, when I try to reformat the date to be in the form dd/mm/yyyy using this code:
var day = ('0' + threeMonthsFromToday.getDate()).slice(-2);
var month = ('0' + threeMonthsFromToday.getMonth() + 1).slice(-2);
var year = threeMonthsFromToday.getFullYear();
var date = day + '/' + month + '/' + year;
I get a completely different and invalid date: 24/31/2017.
I have been debugging this for hours and still can't seem to figure what I am doing wrong.
Well, '0' + threeMonthsFromToday.getMonth() give you a string : "03" then you add 1 converted to string giving you "031" for month before slice.
Use this :
var month = ('0' + (threeMonthsFromToday.getMonth() + 1)).slice(-2);
You are missing the basic BODMAS rule here please modify your code as follows
var today = new Date();
var threeMonthsFromToday = new Date(today.setDate(today.getDate() + 90));
var day = ('0' + threeMonthsFromToday.getDate()).slice(-2);
var month = ('0' + (threeMonthsFromToday.getMonth() + 1)).slice(-2);
var year = threeMonthsFromToday.getFullYear();
var date = day + '/' + month + '/' + year;
the operations are performed from left to right, so month is getting converted to string before being added to a number. Including a bracket will first perform operation inside bracket and then make it a string
Can you use toLocaleString?
threeMonthsFromToday.toLocaleDateString('en-GB')
Below does the trick for you ...
getMonth() +1 before adding the "0" to it so that you get an arithematic +1
var today = new Date();
var threeMonthsFromToday = new Date(today.setDate(today.getDate() + 90));
var day = ('0' + threeMonthsFromToday.getDate()).slice(-2);
var month = ('0' + (threeMonthsFromToday.getMonth()+1)).slice(-2);
var year = threeMonthsFromToday.getFullYear();
var date = day + '/' + month + '/' + year;
console.log(date);
This should work.
var day = threeMonthsFromToday.getDate()
if(day < 10){
day = '0' + day
}
var month = threeMonthsFromToday.getMonth()+1
if(month<10){
month = '0' + month
}
var year = threeMonthsFromToday.getFullYear()
var date = day + '/' + month + '/' + year
Use Simple toLocaleDateString method
The toLocaleDateString() method returns a string with a language sensitive representation of the date portion of this date.
var today = new Date();
var threeMonthsFromToday = new Date(today.setDate(today.getDate() + 90));
var date = threeMonthsFromToday.toLocaleDateString();
console.log(date);
//result in console : "24/04/2017"
Try it out on your console.
I'm new to javascript and I'm trying to generate a date that is:
A.) Formatted (mm/dd/yyyy)
B.) Displayed as three months later than the actual date.
I've spliced together a few things I could find and is seems to work to return the correct date, but I'm concerned it will break later in the year. Is there a better way to accomplish what I'm trying to do? The script is below, thanks in advance for the help.
<script type="text/javascript">
var dt = new Date();
var month = dt.getMonth();
var day = dt.getDate();
var year = dt.getFullYear();
if (month == 9) { var dt = new Date();
var month = dt.getMonth()-8;
var day = dt.getDate();
var year = dt.getFullYear();
var next_year = dt.getFullYear()+1;
document.write(month + '-' + day + '-' + next_year)}
else if (month == 10) { var dt = new Date();
var month = dt.getMonth()-8;
var day = dt.getDate();
var year = dt.getFullYear();
var next_year = dt.getFullYear()+1;
document.write(month + '-' + day + '-' + next_year)}
else if (month == 11) { var dt = new Date();
var month = dt.getMonth()-8;
var day = dt.getDate();
var year = dt.getFullYear();
var next_year = dt.getFullYear()+1;
document.write(month + '-' + day + '-' + next_year)}
else { var dt = new Date();
var month = dt.getMonth()+4;
var day = dt.getDate();
var year = dt.getFullYear();
document.write(month + '-' + day + '-' + year);}
</script>
The date object has methods that allows not only to set month, date and year, but get too.
function getMyDate() {
var date = new Date();
date.setMonth(date.getMonth() + 3);
return (date.getMonth() + 1) + '-' + date.getDate() + '-' + date.getFullYear();
}
document.write(getMyDate());
P.S. The scope of var is the function, not block {}. So, if you declared var dt at the top of your scope, you mustn’t use var dt in if statement. It’s a mistake.
You don't need to worry about dealing with the last three months of the year. Adding three months to a a date that causes it to 'overflow' will correctly set it to next year (eg adding three months to November 2015 will produce a date in February 2016).
var dt = new Date();
dt.setMonth(dt.getMonth() + 3);
document.write((dt.getMonth() + 1) + "-" + dt.getDate() + "-" + dt.getFullYear();
For what it's worth, your code looks correct. Just unnecessarily complex.
To print todays date you should concat the date values:
var d = new Date();
var str = (d.getMonth() + 1) + '/' + d.getDate() + '/' + d.getFullYear();
if you want to add months to your date:
var d = new Date();
var threeMonthsFromToday = new Date(new Date(d).setMonth(d.getMonth()+3));
var str = (d.getMonth() + 1) + '/' + d.getDate() + '/' + d.getFullYear();
I am trying to get a date to refresh on a page so I don't have to go and manually refresh it everyday. I have this code in place, but it doesn't seem to be working. The date displays, but it doesn't update when the day changes. For reference, this is being used on a BrightSign display. Can anyone tell me what I'm doing wrong? I'm kind of a JavaScript beginner so nothing too complex :)
<script type="text/javascript">
<!--
function clockTick() {
currentTime = new Date();
month = currentTime.getMonth() + 1;
day = currentTime.getDate();
year = currentTime.getFullYear();
setInterval(clockTick, 1000);
return (month + "/" + day + "/" + year);
}
document.write(clockTick());
//-->
</script>
You will want to take the setInterval out of the function and set the time on the page inside the function so that it refreshes every second:
function clockTick() {
var currentTime = new Date(),
month = currentTime.getMonth() + 1,
day = currentTime.getDate(),
year = currentTime.getFullYear(),
hours = currentTime.getHours(),
minutes = currentTime.getMinutes(),
seconds = currentTime.getSeconds(),
text = (month + "/" + day + "/" + year + ' ' + hours + ':' + minutes + ':' + seconds);
// here we get the element with the id of "date" and change the content to the text variable we made above
document.getElementById('date').innerHTML = text;
}
// here we run the clockTick function every 1000ms (1 second)
setInterval(clockTick, 1000);
<span id="date"></span>
you can try this:call clockTick() from outside.
function clockTick() {
currentTime = new Date();
month = currentTime.getMonth() + 1;
day = currentTime.getDate();
year = currentTime.getFullYear();
// alert("hi");
document.getElementById('date').innerHTML=month + "/" + day + "/" + year;
}
setInterval(function(){clockTick();}, 1000);//setInterval(clockTick, 1000); will also work
<div id="date"></div>
I want to know how to use the Date() function in jQuery to get the current date in a yyyy/mm/dd format.
Date() is not part of jQuery, it is one of JavaScript's features.
See the documentation on Date object.
You can do it like that:
var d = new Date();
var month = d.getMonth()+1;
var day = d.getDate();
var output = d.getFullYear() + '/' +
(month<10 ? '0' : '') + month + '/' +
(day<10 ? '0' : '') + day;
See this jsfiddle for a proof.
The code may look like a complex one, because it must deal with months & days being represented by numbers less than 10 (meaning the strings will have one char instead of two). See this jsfiddle for comparison.
If you have jQuery UI (needed for the datepicker), this would do the trick:
$.datepicker.formatDate('yy/mm/dd', new Date());
jQuery is JavaScript. Use the Javascript Date Object.
var d = new Date();
var strDate = d.getFullYear() + "/" + (d.getMonth()+1) + "/" + d.getDate();
Using pure Javascript your can prototype your own YYYYMMDD format;
Date.prototype.yyyymmdd = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
var dd = this.getDate().toString();
return yyyy + "/" + (mm[1]?mm:"0"+mm[0]) + "/" + (dd[1]?dd:"0"+dd[0]); // padding
};
var date = new Date();
console.log( date.yyyymmdd() ); // Assuming you have an open console
In JavaScript you can get the current date and time using the Date object;
var now = new Date();
This will get the local client machine time
Example for jquery LINK
If you are using jQuery DatePicker you can apply it on any textfield like this:
$( "#datepicker" ).datepicker({dateFormat:"yy/mm/dd"}).datepicker("setDate",new Date());
function GetTodayDate() {
var tdate = new Date();
var dd = tdate.getDate(); //yields day
var MM = tdate.getMonth(); //yields month
var yyyy = tdate.getFullYear(); //yields year
var currentDate= dd + "-" +( MM+1) + "-" + yyyy;
return currentDate;
}
Very handy function to use it, Enjoy. You do not require any javascript framework. it just works in with plain javascript.
I know I am Late But This Is All You Need
var date = (new Date()).toISOString().split('T')[0];
toISOString() use built function of javascript.
cd = (new Date()).toISOString().split('T')[0];
console.log(cd);
alert(cd);
Since the question is tagged as jQuery:
If you are also using jQuery UI you can use $.datepicker.formatDate():
$.datepicker.formatDate('yy/mm/dd', new Date());
See this demo.
Here is method top get current Day, Year or Month
new Date().getDate() // Get the day as a number (1-31)
new Date().getDay() // Get the weekday as a number (0-6)
new Date().getFullYear() // Get the four digit year (yyyy)
new Date().getHours() // Get the hour (0-23)
new Date().getMilliseconds() // Get the milliseconds (0-999)
new Date().getMinutes() // Get the minutes (0-59)
new Date().getMonth() // Get the month (0-11)
new Date().getSeconds() // Get the seconds (0-59)
new Date().getTime() // Get the time (milliseconds since January 1, 1970)
See this.
The $.now() method is a shorthand for the number returned by the expression (new Date).getTime().
Moment.js makes it quite easy:
moment().format("YYYY/MM/DD")
this object set zero, when element has only one symbol:
function addZero(i) {
if (i < 10) {
i = "0" + i;
}
return i;
}
This object set actual full time, hour and date:
function getActualFullDate() {
var d = new Date();
var day = addZero(d.getDate());
var month = addZero(d.getMonth()+1);
var year = addZero(d.getFullYear());
var h = addZero(d.getHours());
var m = addZero(d.getMinutes());
var s = addZero(d.getSeconds());
return day + ". " + month + ". " + year + " (" + h + ":" + m + ")";
}
function getActualHour() {
var d = new Date();
var h = addZero(d.getHours());
var m = addZero(d.getMinutes());
var s = addZero(d.getSeconds());
return h + ":" + m + ":" + s;
}
function getActualDate() {
var d = new Date();
var day = addZero(d.getDate());
var month = addZero(d.getMonth()+1);
var year = addZero(d.getFullYear());
return day + ". " + month + ". " + year;
}
HTML:
<span id='full'>a</span>
<br>
<span id='hour'>b</span>
<br>
<span id='date'>c</span>
JQUERY VIEW:
$(document).ready(function(){
$("#full").html(getActualFullDate());
$("#hour").html(getActualHour());
$("#date").html(getActualDate());
});
EXAMPLE
//convert month to 2 digits<p>
var twoDigitMonth = ((fullDate.getMonth().length+1) === 1)? (fullDate.getMonth()+1) : '0' + (fullDate.getMonth()+1);
var currentDate = fullDate.getFullYear()+ "/" + twoDigitMonth + "/" + fullDate.getDate();
console.log(currentDate);<br>
//2011/05/19
You can achieve this with moment.js as well.
Include moment.js in your html.
<script src="moment.js"></script>
And use below code in script file to get formatted date.
moment(new Date(),"YYYY-MM-DD").utcOffset(0, true).format();
FYI - getDay() will give you the day of the week... ie: if today is Thursday, it will return the number 4 (being the 4th day of the week).
To get a proper day of the month, use getDate().
My example below... (also a string padding function to give a leading 0 on single time elements. (eg: 10:4:34 => 10:04:35)
function strpad00(s)
{
s = s + '';
if (s.length === 1) s = '0'+s;
return s;
}
var currentdate = new Date();
var datetime = currentdate.getDate()
+ "/" + strpad00((currentdate.getMonth()+1))
+ "/" + currentdate.getFullYear()
+ " # "
+ currentdate.getHours() + ":"
+ strpad00(currentdate.getMinutes()) + ":"
+ strpad00(currentdate.getSeconds());
Example output: 31/12/2013 # 10:07:49If using getDay(), the output would be 4/12/2013 # 10:07:49
This will give you current date string
var today = new Date().toISOString().split('T')[0];
Try this....
var d = new Date();
alert(d.getFullYear()+'/'+(d.getMonth()+1)+'/'+d.getDate());
getMonth() return month 0 to 11 so we would like to add 1 for accurate month
Reference by : https://www.w3schools.com/jsref/jsref_obj_date.asp
you can use this code:
var nowDate = new Date();
var nowDay = ((nowDate.getDate().toString().length) == 1) ? '0'+(nowDate.getDate()) : (nowDate.getDate());
var nowMonth = ((nowDate.getMonth().toString().length) == 1) ? '0'+(nowDate.getMonth()+1) : (nowDate.getMonth()+1);
var nowYear = nowDate.getFullYear();
var formatDate = nowDay + "." + nowMonth + "." + nowYear;
you can find a working demo here
var d = new Date();
var today = d.getFullYear() + '/' + ('0'+(d.getMonth()+1)).slice(-2) + '/' + ('0'+d.getDate()).slice(-2);
The jQuery plugin page is down. So manually:
function strpad00(s)
{
s = s + '';
if (s.length === 1) s = '0'+s;
return s;
}
var now = new Date();
var currentDate = now.getFullYear()+ "/" + strpad00(now.getMonth()+1) + "/" + strpad00(now.getDate());
console.log(currentDate );
console.log($.datepicker.formatDate('yy/mm/dd', new Date()));
Using the jQuery-ui datepicker, it has a handy date conversion routine built in so you can format dates:
var my_date_string = $.datepicker.formatDate( "yy-mm-dd", new Date() );
Simple.
This is what I came up with using only jQuery. It's just a matter of putting the pieces together.
//Gather date information from local system
var ThisMonth = new Date().getMonth() + 1;
var ThisDay = new Date().getDate();
var ThisYear = new Date().getFullYear();
var ThisDate = ThisMonth.toString() + "/" + ThisDay.toString() + "/" + ThisYear.toString();
//Gather time information from local system
var ThisHour = new Date().getHours();
var ThisMinute = new Date().getMinutes();
var ThisTime = ThisHour.toString() + ":" + ThisMinute.toString();
//Concatenate date and time for date-time stamp
var ThisDateTime = ThisDate + " " + ThisTime;
You can do this:
var now = new Date();
dateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT");
// Saturday, June 9th, 2007, 5:46:21 PM
OR Something like
var dateObj = new Date();
var month = dateObj.getUTCMonth();
var day = dateObj.getUTCDate();
var year = dateObj.getUTCFullYear();
var newdate = month + "/" + day + "/" + year;
alert(newdate);
var d = new Date();
var month = d.getMonth() + 1;
var day = d.getDate();
var year = d.getYear();
var today = (day<10?'0':'')+ day + '/' +(month<10?'0':'')+ month + '/' + year;
alert(today);
I just wanted to share a timestamp prototype I made using Pierre's idea. Not enough points to comment :(
// US common date timestamp
Date.prototype.timestamp = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
var dd = this.getDate().toString();
var h = this.getHours().toString();
var m = this.getMinutes().toString();
var s = this.getSeconds().toString();
return (mm[1]?mm:"0"+mm[0]) + "/" + (dd[1]?dd:"0"+dd[0]) + "/" + yyyy + " - " + ((h > 12) ? h-12 : h) + ":" + m + ":" + s;
};
d = new Date();
var timestamp = d.timestamp();
// 10/12/2013 - 2:04:19
Get current Date format dd/mm/yyyy
Here is the code:
var fullDate = new Date();
var twoDigitMonth = ((fullDate.getMonth().toString().length) == 1)? '0'+(fullDate.getMonth()+1) : (fullDate.getMonth()+1);
var twoDigitDate = ((fullDate.getDate().toString().length) == 1)? '0'+(fullDate.getDate()) : (fullDate.getDate());
var currentDate = twoDigitDate + "/" + twoDigitMonth + "/" + fullDate.getFullYear();
alert(currentDate);
function createDate() {
var date = new Date(),
yr = date.getFullYear(),
month = date.getMonth()+1,
day = date.getDate(),
todayDate = yr + '-' + month + '-' + day;
console.log("Today date is :" + todayDate);
You can add an extension method to javascript.
Date.prototype.today = function () {
return ((this.getDate() < 10) ? "0" : "") + this.getDate() + "/" + (((this.getMonth() + 1) < 10) ? "0" : "") + (this.getMonth() + 1) + "/" + this.getFullYear();
}
This one-liner will give you YYYY-MM-DD:
new Date().toISOString().substr(0, 10)
'2022-06-09'
