In this tutorial we will create a Simple Digital Clock using Javascript. JavaScript is a scripting or programming language that allows you to implement complex things on web pages. It is widely used in designing a stunning website. It is an interpreted programming language that has a capabilities of Object-Oriented. This code can be used to your system that needed a timestamp. So Let's do the coding.
Before we started:
First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html.
And this is the link for the bootstrap that has been used for the layout of the calculator https://getbootstrap.com/.
The Main Interface
This code contains the interface of the application. This code will render application and display a digital clock. To create this just write these block of code inside the text editor and save this as index.html
Creating the Script
This code contains the script of the application. This code will render a digital clock that runs base on you computer clock. To do this just copy write the code as shown below inside the text editor and save it as clock.js
There you have it we successfully created a Simple Digital Clock using Javascript. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!!!

Creating the Script
This code contains the script of the application. This code will render a digital clock that runs base on you computer clock. To do this just copy write the code as shown below inside the text editor and save it as clock.js
- function
DisplayTime(
)
{
- var
date =
new
Date
(
)
;
- var
hour =
date.getHours
(
)
;
- var
minute =
date.getMinutes
(
)
;
- var
seconds =
date.getSeconds
(
)
;
- var
day =
"AM"
- if
(
hour ==
0
)
{
- hour =
12
;
- }
- if
(
hour >
12
)
{
- hour-=
12
;
- day =
"PM"
- }
- hour =
(
hour <
10
)
?
"0"
+
hour :
hour;
- minute =
(
minute <

)
?
"0"
+
minute :
minute;
- seconds =
(

day;
- document.getElementById

)
.innerText
