Hello Friends My Name Is Viraj,Today I Will Display Clock On Your Web Page.We can display a clock which will be showing the local time of the client computer by using JavaScript. Note that this time displayed is taken from user computer and not from the server.We have seen in our date object example how to display current date and time where the current date and time is displayed once. Here we will try to display changing clock or real time change in date and time by using setTimeout function. This setTimeout function we have used to trigger the time display function in a refresh rate of 1000 mill seconds ( 1 Sec ). This refresh rate can be changed to any other value. By changing the value to 5000 the clock will refresh and show the exact time once in every 5 seconds. Here you can build your own HTML-based clock widget in just a few clicks, paste it into your webpage or blog and display time and date of the selected time zone or location. The clock is based on HTML and JavaScript and the service is entirely free of charge.This generator allows you to create the Javascript code necessary to put a text clock on your website that can display the current time (and date). The clock keeps updating in real time. Multiple time and date formats to choose from.In this article, I am going to show you how to design a simple animated Digital Clock in JavaScript. Since, a browser executes a JavaScript program at the client side, the script will pick up the time of the client’ computer and display it.JavaScript Date object is used to work with dates and times. Date object is created with new Date(). Using Date object, you can create a digital clock in JavaScript. In this article, we’ll show the simplest way to make a digital clock with date using JavaScript. Our easy to use JavaScript code helps to create a digital clock in your web project instantly.In startTime() function, new Date() is used to define the current Date object. Hours, Minutes, Seconds, Day, Date, Month, and Year are extracted from the Date object using getHours(), getMinutes(), getSeconds(), getDay(), getDate(), getMonth(), and getFullYear() respectively.At the end of startTime() function, setTimeout() method is used to calls startTime() function every 500 milliseconds. On page load startTime() is executed by the <body> onload event attribute.Here you can get three types of clock format, clock with 24 hours, clock with 12 hours, and clock with current date. At first, the javaScript code is provided and then the HTML code.Here In This Html Tutorial We Will Create To Display Clock In Html/Css/Javascript Code.
