Dynamic date and time with moment.js and setInterval

Question

I\'m trying to find out how I can display dynamic date and time using moment.js.

Apparently I can\'t figure out to use setInterval properly.

If possible I\'d pre

Answer 1

I've made a few modifications in your code:

Note that the method update is now outside the ready event handler

code:

var datetime = null,
        date = null;

var update = function () {
    date = moment(new Date())
    datetime.html(date.format('ffffdd, MMMM Do YYYY, h:mm:ss a'));
};

$(document).ready(function(){
    datetime = $('#datetime')
    update();
    setInterval(update, 1000);
});

working demo: jsfiddle

Answer 2

Again, thanks for your answers. The code I ended up with follows. (Note danish i18n)

moment.lang('da');

var datetime = null, date = null;

var datetime_update = function() {
  date = moment(new Date());
  datetime.html(date.format('[Lige nu: ] ffffdd [d.] Do MMMM YYYY [kl.] HH:mm:ss'));
};

$(document).ready(function() {
  datetime = $('#datetime');
  datetime_update();
  setInterval(datetime_update, 1000);
});

EDIT: Here nine months after I asked this quesiton I figured out this way to do it without jQuery (as I initially asked). Here it is:

function date_time() {
  now = moment().format('ffffdd [d.] Do MMMM YYYY [kl.] HH:mm:ss');
  document.getElementById('timer').innerHTML = now;
  setTimeout(function () { date_time(); }, 1000);
}
date_time();

And then of course use it with an HTML ID like:

<span id="timer"></span>

This is how it goes by me and its working u can check it here

HTML

< asp:Label ID="Label1" runat="server" Text='' >

JavaScript
< script language="javascript" type="text/javascript">
function date_time() 
{
var dt = new Date();
document.getElementById('<%=Label1.ClientID%>').innerHTML = dt;
setTimeout(function () { date_time(); }, 1000);
}
date_time();
< /script>

Answer 4

Put

date = moment(new Date());

inside the update function. Now you're just printing the same date every second ;)
