Javascript: Adding digits without Sum?

Question

Javascript: Adding digits without Sum?

I'm basically trying to get the hours, minutes, and seconds of a date in javascript to read like this: '123456'. I am doing this with the following code:

var date;
date = new Date();
var time = date.getUTCHours() + date.getUTCMinutes() + date.getUTCSeconds();

Only problem is when I add them together, I keep getting the sum, not a nice line of 6 numbers like I want.

Any Suggestions?

javascript
node.js
time

Answer 1

Convert the numerical value to a string:

var date;
date = new Date();
var time = date.getUTCHours().toString() + date.getUTCMinutes().toString() + date.getUTCSeconds().toString();

If you want it to always be 6 characters long, you need to pad the values if they are < 10. For example:

var hours = date.getUTCHours();
if (hours < 10)
     hours = '0' + hours.toString();
else hours = hours.toString();

var mins = date.getUTCMinutes();
if (mins < 10)
     mins = '0' + mins.toString();
else mins = mins.toString();

var secs = date.getUTCSeconds();
if (secs < 10)
     secs = '0' + secs.toString();
else secs = secs.toString();

var time = hours + mins + secs;

Answer 2

var time = '' + date.getUTCHours() + date.getUTCMinutes() + date.getUTCSeconds();

edit: To account for zero-padding you can do something like:

function format(x){
    if (x < 10) return '0' + x;
    return x;
}

var date;
date = new Date();
var time = '' + format(date.getUTCHours()) + format(date.getUTCMinutes()) + format(date.getUTCSeconds());

That's happening because those functions return an Integer type. If you want to add the digits themself togheter, try converting every variable to string using toString()
