There are so much warnings , please bear with me and please open the output in new tab. Thank You,
Read the docs about the Date Object: http://www.w3schools.com/jsref/jsref_obj_date.asp.
Everything you need is described there.
Have a look at the following code:
<!DOCTYPE html>
<html>
<body>
<input id="dateInput" type="text"></input>
<button id="convertButton">Convert to string</button>
<a id="dateString"></a>
<script type="text/javascript">
var dateInput = document.getElementById("dateInput");
var button = document.getElementById("convertButton");
var dateString = document.getElementById("dateString");
var date;
button.onclick = function() {
var year = 2000+ parseInt(dateInput.value.split("/")[2]);
var month = dateInput.value.split("/")[0];
var day = dateInput.value.split("/")[1];
date = new Date(year, month, day);
dateString.innerHTML = date.toDateString();
}
</script>
</body>
</html>
This html page does exactly what you want.

I'm using a CMS system that works alongside a backend that we must use. I'm trying to have it display a production lead time date such as www.customink.com. Current day +10 business days I'm using a HTML widget in this custom CMS, so I'm not sure if that is relevant. I'm struggling getting it to show up, and I really have no idea what I'm doing. I tried my best lol. Here's what I have thus far.
EDIT: Also, If I want it to only display M-F how do I go about that? I want it to read - Guaranteed by Fri, Oct 11.
<html>
<body>
<script>
document.getElementById("p1").innerHTML = newDate;
function addDays(theDate, days) {
return new Date(theDate.getTime() + days*24*60*60*1000);
}
var newDate = addDays(new Date(), 10);;
</script>
</body>
</html>
document.getElementById("p1").innerHTML = newDate;
In this statement, what you are doing is trying to find the DOM element with id p1 and then setting the value of newDate variable as its value. Therefore you should define an element with such id before your script block.
Then you are declaring and setting the value of the newDate after you have set the value for the above element. But you should do it before that.
See the fixed code below.
(I have used a <div> element as the p1 element. But you can use any other options such as <span>, <h1>, <h2>, etc. based on your requirement.)
<html>
<head>
<script src='https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js'></script>
</head>
<body>
<div id='p1'></div>
<script>
var newDate = addDays(new Date(), 10);
document.getElementById("p1").innerHTML = formatDate(newDate);
function addDays(theDate, days) {
//return new Date(theDate.getTime() + days*24*60*60*1000);
return moment(theDate).add(days, 'd').toDate();
}
function formatDate(date) {
return moment(date).format('[Guaranteed by] ddd, MMM DD');
}
</script>
</body>
</html>
I need to add a date and time clock to a website. It should display the date and time in a very specific format, taking up two lines and using an intended timezone of GMT-4; for example:
Sat, Mar 23 2019
10:33:56 PM
This happens to be for a school project, but I have limited knowledge of Javascript. I've tried looking up some examples and have found some interesting stuff, but I'm unable to adapt those examples to generate the output in the desired format.
Please Try This
function display_c(){
var refresh=1000; // Refresh rate in milli seconds
mytime=setTimeout('display_ct()',refresh)
}
function display_ct() {
var CDate = new Date()
var NewDate=CDate.toDateString();
NewDate = NewDate + " - " + CDate.toLocaleTimeString();
document.getElementById('ct').innerHTML = NewDate;
display_c();
}
<html>
<head> </head>
<body onload=display_ct();>
<span id='ct' ></span>
</body>
</html>
For Change Date Or Time Format Please Refer this link
Get currentDate by toDateString() method and get current time by toLocaleTimeString and append both in your DOM . And call this every 1000 ms to get updated value .
function callDateTime(){
var currentDate=(new Date()).toDateString();
var currentTime=(new Date()).toLocaleTimeString();
document.getElementById('watch').innerHTML=`${currentDate}-${currentTime}`;
}
setInterval(function(){ callDateTime() }, 1000);
<p id="watch"></p>
You can add an HTML to your the body of your document:
Also, you can add a JavaScript similar to this before </body>:
Code:
function clock(){
window.rt=1000;r=0;
document.getElementById('t-0').textContent=new Date().toLocaleDateString(); // today
var m=setInterval(function(){
if(r>84600){clearInterval(m);}
r++;
document.getElementById('t-2').textContent=new Date().toLocaleTimeString(); // clock
}, window.rt);
}
<!DOCTYPE html>
<html lang="en">
<title>Clock</title>
<body onload="clock();">
<div style="text-align:center;">
📅
<b id="t-0">00/00/0000</b>
⏰
<b id="t-2">00:00:00</b>
</div>
</body>
</html>
I have 2 Date Objects. One is from and another contains to.
The date format used is "YYYY-MM-DD".
My problem is that I am using a charting tool and I have to map dates
on charting tool based on data.
So I need to divide this From and To Date based on data
if I have a selection from 2015-10-9 to 2015-12-23
I can break this down into n number of selection. Usually data length to be represented on x axis is 10 at max.
Yes, here's working code.
function test(){
var a=new Date(2015, 00, 01);
var b=new Date(2015, 05, 07);
ret=divideDates(a, b);
document.getElementById("results").innerHTML+="Start Date was: "+a.toString()+"<br/><hr />";
for(var key in ret){
document.getElementById("results").innerHTML+="<br />"+ret[key];
}
document.getElementById("results").innerHTML+="<br/><hr />End Date was: "+b.toString();
}
function divideDates(startDate, endDate){
var thediff=endDate-startDate;
var thetenth=thediff/10;
var resp = [];
for(i=1; i<=10; i++){
var toAdd=thetenth*i;
resp[i]=new Date(startDate.getTime()+toAdd);
}
return resp;
}
and here is a test HTML page i used (obv.ly call the js file "func.js"):
<html>
<head>
<script language="JavaScript" src="func.js"></script>
</head>
<body>
<input type="button" onclick="javascript:test();" value="testIT">
<div id="results">
</div>
</body>
</html>
<html>
<head>
<title>Test Environment</title>
</head>
<body>
<script>
document.bgColor="#222222";
document.fgColor="#11EE11";
document.writeln("Test Environment.");
document.writeln("Last Update: " + document.lastModified);
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
if(dd<10) {
dd='0'+dd
}
if(mm<10) {
mm='0'+mm
}
today = dd+'/'+mm+'/'+yyyy;
function enterExpenses(){
var _desc = window.prompt("What kind of expenses?");
var _amount = window.prompt("Amount spent?");
var _entry = {type:_desc amount:_amount date:today};
document.writeln(_entry.date);
document.writeln(_entry.type);
document.writeln(_entry.amount);
}
</script>
<form>
<button onclick="enterExpenses()">Click me</button>
</form>
</body>
</html>
I hate to be the guy asking others to do my work but I can't figure out why it doesn't work. I'm trying to learn javascipt and I've completed the codecademy course. Now I'm actually trying to work with it and put it to use and I can't figure out why my script is not executed.
Anyone's expertise I can borrow for a second?
Maybe it is because of a typo in this line
var _entry = {type:_desc amount:_amount date:today};
You should separate object properties by a comma
var _entry = {type:_desc, amount:_amount, date:today};
Aside form Muhammad's answer, use this for your button:
<button type="button" onclick="enterExpenses()">Click me</button>
Not specifying the "type" attribute for buttons will make it a submit button, sending your form to the form's action page.
I have tried to implement the date picker in android. I want it to get the data and show it in the text format
<html>
<head>
<script type="text/javascript" charset="utf-8" src="cordova-2.5.0.js"></script>
<script type="text/javascript" charset="utf-8" src="datePickerPlugin.js"></script>
<script type="text/javascript" charset="utf-8">
function dateTest() {
var myNewDate = new Date();
window.plugins.datePicker.show({
date : myNewDate,
mode : 'date', // date or time or blank for both
allowOldDates : true
}, function(returnDate) {
var newDate = new Date(returnDate);
currentField.val(newDate.toString("dd/MMM/yyyy"));
// This fixes the problem you mention at the bottom of this script with it not working a second/third time around, because it is in focus.
currentField.blur();
});
}
</script>
</head>
<body bgcolor="#ffffff">
<hr>DatePicker Test<hr><br>
<input type="button" onClick ="dateTest()" value ="Today's Date!!" />
<div id="view"></div>
</body>
</html>
I am getting it as an alert...but unable to store it as a string on the same page
Why loose ur head?
A <input type="date"> will allways deppend on device's interpretation of it, in some android devices it doesn't even work,
There is plenty of plugins, addons, whatever, for it,
I personally like, and use mobiscroll: Link
Edit: Mobiscroll is now paid but there are loads of free frontend mobile frameworks and probably all of them have a datepicker, such as jQuery Mobile-datepicker.
It seems that your currentField is undefined. Did you check the chrome console before running it on AVD ? Pls try to post the element in which you are trying to display the date as well.
For now, I am assuming that you are trying to do what the following code does
$('.nativedatepicker').focus(function(event) {
var currentField = $(this);
var myNewDate = new Date(Date.parse(currentField.val())) || new Date();
// Same handling for iPhone and Android
window.plugins.datePicker.show({
date : myNewDate,
mode : 'date', // date or time or blank for both
allowOldDates : true
}, function(returnDate) {
var newDate = new Date(returnDate);
var newString = newDate.toString();
newString = newString.substring(0,15);
currentField.val(newString);
// This fixes the problem you mention at the bottom of this script with it not working a second/third time around, because it is in focus.
currentField.blur();
});
});
The element is as follows
<input type="text" class="nativedatepicker" readonly value = "Fri Jun 21 2013"/>
Works like a charm !! Hope it helps !!
What I want to happen is simple - I just want a datepicker to display when I click a certain field.
However, the same as Aleks, I don't know what to put in my html, how to use it in html, and what should I put in the html to invoke the datepicker on some input.
The documentation from the plugin is incomplete.
I found a solution from this test project.
Steps are as follows:
Pre-requisite: phonegap/cordova-cli installed
Install Cordova's device plugin: $ cordova plugin add org.apache.cordova.device
Install Dirk's datepicker plugin: $ cordova plugin add https://github.com/DURK/cordova-datepicker-plugin
Copy the nativedatepicker.js from the test project and place it on your project's js folder. This file has showDatePicker(), showDateTimePicker() convenience functions.
Add the ff. to index.html code:
Note: The datepicker won't show when you test it in your browser
....
<div class="form-group">
<label>Appointment</label>
<input type="text" class="form-control datepicker" id="appointment">
</div>
....
<script src="js/nativedatepicker.js"></script>
<script src="cordova.js"></script>
<script type="text/javascript">
(function($){
$(document).ready(function () {
$(document).on('click', '.datepicker', function () {
showDatePicker($(this), 'date');
});
$(document).on('click', '.timepicker', function () {
showDatePicker($(this), 'time');
});
$(document).on('click', '.datetimepicker', function () {
if (device.platform === "Android")
showDateTimePicker($(this));
else
showDatePicker($(this), 'datetime');
});
});
})(jQuery);
</script>
This is my working implementation. Input type is text, readonly.
$('.nativedatepicker').focus(function(event) {
var currentField = $(this);
var myNewDate = new Date();
window.plugins.datePicker.show({
date : myNewDate,
mode : 'date',
allowOldDates : true
}, function(returnDate) {
var array = returnDate.split("/");
var day = array[2], month = array[1];
if (day <= 9)
day = "0" + day;
if (month <= 9)
month = "0" + month;
currentField.val(array[0] + "/" + month + "/" + day);
currentField.blur();
});
});
Why would you want to implement a custom date picker if there is an ative one available ?
You can simply use <input type="date"> to create the commonly known iOS date picker.
