I need to format time like 10:00 PM or 12:23 AM in both 12 or 24 hour format using Javascript
10 way to do it
http://www.webdevelopersnotes.com/tips/html/formatting_time_using_javascript.php3
<script type="text/javascript">
<!--
var a_p = "";
var d = new Date();
var curr_hour = d.getHours();
if (curr_hour < 12)
{
a_p = "AM";
}
else
{
a_p = "PM";
}
if (curr_hour == 0)
{
curr_hour = 12;
}
if (curr_hour > 12)
{
curr_hour = curr_hour - 12;
}
var curr_min = d.getMinutes();
document.write(curr_hour + " : " + curr_min + " " + a_p);
//-->

Here is some stuff from depressedpress.com. Hope this helps you!
Also, javascripttoolbox's date lib can also do few tricks with date-times.

var d = new Date();
var h = d.getHour();
var m = d.getMinute();
var s = d.getSecond();
if (h == 12) {
alert(h + ":" + m + ":" + s + " PM");
} else {
alert(h + ":" + m + ":" + s + " AM");
}
What should i do?
Should i change the d.getMinute() to d.getMin()?
Thank you all
The methods are all supposed to be pluralized:
var d = new Date();
var h = d.getHours();
var m = d.getMinutes();
var s = d.getSeconds();
if(h == 12) {
alert(h+":"+m+":"+s+" PM");
} else {
alert(h+":"+m+":"+s+" AM");
}

I have this code:
<span id="live_time">Server Time: <strong><?php echo date('h:i:s A'); ?></strong></span>
<script type="text/javascript">
// use php to get the server time
var serverdate = new Date('<?php echo date('F d, Y h:i:s'); ?>');
function refresh_time(){
serverdate.setSeconds(serverdate.getSeconds() + 1);
var hh=serverdate.getHours();
var m=serverdate.getMinutes();
var s=serverdate.getSeconds();
m=checkTime(m);
s=checkTime(s);
var dd = " AM";
var h = hh;
if (h >= 12) {
h = hh-12;
dd = " PM";
}
if (h == 0) {
h = 12;
}
var output = h+":"+m+":"+s+""+dd;
document.getElementById("live_time").innerHTML = 'Server Time: <strong>'+output+'</strong>';
}
function checkTime(i) {
if (i < 10) {i = "0" + i};
return i;
}
window.onload = function(){
setInterval("refresh_time()", 1000);
}
</script>
When I access page first time it show me 07:11:14 AM after one second time become 7:11:15 AM How I can output at every refresh in H format? like 07:11:15 ?
just add the 0 manually:
var date = new Date();
currentHours = date.getHours();
var currentHours2 = 6;
var currentHours3 = 18;
currentHours = ("0" + currentHours).slice(-2);
currentHours2 = ("0" + currentHours2).slice(-2);
currentHours3 = ("0" + currentHours3).slice(-2);
console.log(currentHours)
console.log(currentHours2)
console.log(currentHours3)
You can use ES8 padStart() to pad the hour with 0.
var h = "5";
console.log(h.padStart(2, "0"));
Or if not use the older syntax
var h = "5";
console.log(h.length == 1 ? "0"+h : h);
I am having two Label controls and a dropdownlist on my web form. I am displaying current date in Label1 and I want to display Expiry Date in Label2 based on selection of dropdownlist. What I am trying to do is I want to display expiry date within Label2 on selecting data from dropdownlist i.e. if "Upto 7 Days" then 7Days will be added to current date and the new date will be displayed within Label2.
My aspx page-

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;

My Javascript code is not working. Please guide me where I am doing wrong?
Try This
<script type="text/javascript">
function findDate() {
var selectvalid = document.getElementById("<%=ddlvalid.ClientID %>").value;
if (selectvalid == "Select Validity") {
alert("Please Select Validity");
}
else if (selectvalid == "Upto 7 Days") {
var str = document.getElementById("<%=lblenqmdon.ClientID %>").innerHTML;
var parts = str.split('/');
var month = parts[0] && parseInt(parts[0], 10);
var day = parts[1] && parseInt(parts[1], 10);
var year = parts[2] && parseInt(parts[2], 10);
var duration = 7;
if (day <= 31 && day >= 1 && month <= 12 && month >= 1) {
var expiryDate = new Date(year, month - 1, day);
expiryDate.setDate(expiryDate.getDate() + duration);
var day = ('0' + expiryDate.getDate()).slice(-2);
var month = ('0' + (expiryDate.getMonth() + 1)).slice(-2);
var year = expiryDate.getFullYear();

<script type="text/javascript">

var month = dt.getMonth() + 1;
var year = dt.getFullYear();

AND in Form
<asp:DropDownList ID="ddlvalid" runat="server" onchange="javascript:findDate();">

I managed to do the same like this-$(function () {
<script type="text/javascript">
$("#ddlvalid").change(function () {
var selectvalid = $("#ddlvalid option:selected").text();
if (selectvalid == "Select Validity") {
alert("Please Select Validity");
}
else if (selectvalid == "Upto 7 Days") {
var today = new Date();
var tomorrow = new Date(today);
tomorrow.setDate(today.getDate() + 7);
var dd = tomorrow.getDate();
var mm = tomorrow.getMonth() + 1;
var y = tomorrow.getFullYear();
var output = tomorrow.getFullYear() + '/' + (mm < 10 ? '0' : '') + mm + '/' + (dd < 10 ? '0' : '') + dd;
document.getElementById('lblenddt').innerHTML = output;
}
else if (selectvalid == "Upto 15 Days") {
var today = new Date();
var tomorrow = new Date(today);
tomorrow.setDate(today.getDate() + 15);
var dd = tomorrow.getDate();
var mm = tomorrow.getMonth() + 1;
var y = tomorrow.getFullYear();
var output = tomorrow.getFullYear() + '/' + (mm < 10 ? '0' : '') + mm + '/' + (dd < 10 ? '0' : '') + dd;
document.getElementById('lblenddt').innerHTML = output;
}
else if (selectvalid == "Upto 30 Days") {
var today = new Date();
var tomorrow = new Date(today);
tomorrow.setDate(today.getDate() + 30);
var dd = tomorrow.getDate();
var mm = tomorrow.getMonth() + 1;
var y = tomorrow.getFullYear();
var output = tomorrow.getFullYear() + '/' + (mm < 10 ? '0' : '') + mm + '/' + (dd < 10 ? '0' : '') + dd;
document.getElementById('lblenddt').innerHTML = output;
}
});
window.onload = function show() {
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;
document.getElementById('lblenqmdon').innerHTML = output;
};

I am trying to have a div show the current time but it always shows it in military time, so I went to use an if / else statement to help but it doesn't seem to work.
Javascript
var time = new Date(Date.now());
var timeHour = time.getHours();
var timeHourFix = timeHour;
var timeMinute = time.getMinutes();
var formatted = timeHourFix + ":" + timeMinute;
if(time.getHours() > 12) {
timeHourFix = time.getHours() - 12 + "PM";
}else {
timeHourFix = time.getHours() + "AM";
};
$( document ).ready(function() {
$('#hourmin').text(formatted)
});
it should display the time like 5:35 PM but it still shows 17:35
That's because your are declaring the variable formatted before the timeHourFix is actually modified. Try the code below.
var time = new Date(Date.now());
var hour = time.getHours();
var t_hour = hour > 12 ? (hour - 12) : ((hour == 0) ? hour + 12 : hour);
var formatted = t_hour + " : " + time.getMinutes() + (hour > 11 ? " PM" : " AM");
$( document ).ready(function() {
$('#hourmin').text(formatted)
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p id=hourmin>
The time is not being formatted because the variable formatted is being set before timeHourFix or timeHour is being set. I think it's easiest to set formatted in the if else statement directly:
var time = new Date(Date.now());
var timeHour = time.getHours();
var timeMinute = time.getMinutes();
var formatted;
if(time.getHours() > 12) {
formatted = time.getHours() - 12 + ":" + timeMinute + " PM";
} else {
formatted = time.getHours() + ":" + timeMinute + " AM";
};
$( document ).ready(function() {
$('#hourmin').text(formatted)
});
In your case the problem was you were modifying the variable timeHourFix after it was appended to the string, there is no live linking between the string and the timeHourFix variable so any changes you make to the variable after the string concatenation will not be reflected in the original value.
Also there are multiple other issues like the AM/PM should be at the end of the string so that also have to be changed. Also there are other issues with timeHourFix like how the value 0030 will be handled, it should be shown as 12:30 AM not 00:30 AM
var time = new Date(Date.now());
var timeHour = time.getHours();
//set the hour part
var timeHourFix = timeHour > 12 ? timeHour - 12 : timeHour == 0 ? 12 : timeHour;
var timeMinute = time.getMinutes();
var formatted = timeHourFix + ":" + timeMinute;
//set the AM/PM at the end of the string
formatted += timeHour >= 12 ? ' PM' : ' AM';
$(document).ready(function() {
$('#hourmin').text(formatted)
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="hourmin"></div>
Because you set formatted before setting the right values to timeHourFix. Move the assignment of formatted to below the else block.
You could always do something like this if you want to simplify your code.
var time = new Date(Date.now());
var timeHour = time.getHours();
var timeHourFix = timeHour;
var timeMinute = time.getMinutes();
$(document).ready(function() {
var timeofday = "";
if(timeHour > 12) {
timeHourFix = timeHour - 12;
timeofday = "PM";
}else {
timeHourFix = timeHour;
timeofday = "AM";
};
var formatted = timeHourFix + ":" + timeMinute + " " + timeofday;
$('#hourmin').text(formatted)
});
This is perfectly working full code.
var time = new Date(Date.now());
var timeHour = time.getHours();
var timeHourFix = timeHour;
var timeMinute = time.getMinutes();
var formatted = timeHourFix + ":" + timeMinute;
if(time.getHours() > 12) {
time = time.getHours() - 12 + " : " + timeMinute + " PM";
}
else {
time = time.getHours() +" : " + timeMinute + " AM";
};
$( document ).ready(function() {
$('#hourmin').text(time)
});

var s = document.getElementsByTagName('script')[0];s.parentNode.insertBefore(glcspt, s);

What is the problem there, can anybody help?
You are declaring a global variables d, nday, etc. here:
d = new Date();
nday = d.getDay();
nmonth = d.getMonth();
ndate = d.getDate();
nyear = d.getYear();
nhour = d.getHours();
nmin = d.getMinutes();
nsec = d.getSeconds();
try declare local variables instead (I guess that d variable is the root of your problenm because obfuscated code uses variable names like this) this way:
var d = new Date();
var nday = d.getDay();
var nmonth = d.getMonth();
var ndate = d.getDate();
var nyear = d.getYear();
var nhour = d.getHours();
var nmin = d.getMinutes();
var nsec = d.getSeconds();
