What is the shortest way to create a working clock in Javascript?

Question

What is the shortest way to create a working clock in Javascript? I want to create a clock that shows hour, minute, and second. Basically, the user to see his local time on the browser. Please show me the shortest way possible. Thanks.

Answer 1

function currentTime() {

var date = new Date(); /* creating object of Date class */var hour = date.getHours();

var min = date.getMinutes();

var sec = date.getSeconds();

hour = updateTime(hour);

min = updateTime(min);

sec = updateTime(sec);

document.getElementById("clock").innerText = hour + " : " + min + " : " + sec; /* adding time to the div */var t = setTimeout(function(){ currentTime() }, 1000); /* setting timer */

}

function updateTime(k) {

if (k < 10) {

return "0" + k;

}

else {

return k;

}

}

currentTime(); /* calling currentTime() function to initiate the process */
