In this blog of Code With Bishal, I am going to show you how can you get the current time in JavaScript. So, stay with me till the end and you will get all the downloadable resources and we will create this project using HTML, CSS and JavaScript.
How can we get the current time using JavaScript?
In this blog, The approach I will use is JavaScript Document Object Model (DOM) onload event. The Document Object Model (DOM) onload event runs when an object has been loaded. In this Project, We are going to call a function using the onload event.
Usage Example:
<body onload="function()"></body>
We can also use addEventListener to check if the object has been loaded
Usage Example:
document.addEventListener("load", function);
So Let's see a quick demo of what are we going to create today
Demo
Step by step guide to get current time using JavaScript:
-
Create a file with the name
index.html -
Open
index.html -
Add the Broiler plate of HTML
Broiler Plate of HTML:
<!DOCTYPE html>
<html>
<head>
<title>How to get current time - Code With Bishal</title>
</head>
<!-- created by Code With Bishal - www.codewithbishal.com

-
Create a file
script.js -
Link External JavaScript file with your HTML file
Here is how can you link:
Add these code in the <head> </head> of your HTML document:
<script src="script.js"></script>
Now add some JavaScript code to the script.js file:
function showTime(){
var date = new Date();
var h = date.getHours();
var m = date.getMinutes();
var s = date.getSeconds();
var time = h + ":" + m + ":" + s;
document.getElementById("cwb-time").innerText = time;
document.getElementById("cwb-time").style.color = "#FFCC70";
document.getElementById("cwb-time").style.fontSize = "70px";
setTimeout(showTime, 1000);
}
