How we can create a date-picker using JavaScript or any JS library? Solution: See this JavaScript Datepicker With jQuery and CSS UI, Form Input Datepicker JS.

Previously I have shared a jQuery UI datepicker, but this program is complete is based on JS (jQuery) without any special library. Basically, datepicker is a type of hidden calendar, which appears on action or click event. When we put our DOB in any form, after clicking on the DOB input field a calendar becomes appear for the select date, month, and year, which is called a datepicker.

Today you will learn to create a form input date picker with JS. Basically, there is a form with 3 fields name, email, and birth date, the first two inputs are basic text inputs. But the third select birth date input has a calendar for choosing your date of birth or any event. When you click on the birth date input, then a calendar will appear with slightly down animation. The calendar has navigation buttons for changing months and years, you can choose your desired date.

So, Today I am sharing JavaScript Datepicker With jQuery and CSS UI design. This program is completely based on JS codes which are powered by jQuery, If we use pure JavaScript then code will little complicated and take more time. This is a complete datepicker program that can be used anywhere as you want, and it has a material type design using CSS.

If you are thinking now how this date picker actually is, then see the preview given below.

Preview Of Date-Picker JS for Forms

See this video preview to getting an idea of how this date picker looks like.

Live Demo

Now you can see this visually, also you can see it live by pressing the button given above. If you like this program, then get the source code of its.

JavaScript Datepicker With jQuery and CSS UI Source Code

Before sharing source code, let’s talk about it. First I have created a form and put a heading, a text, 3 text inputs, some divs, and a submit button inside it. There I have used simple HTML form tag and <input type="text"> for creating the fields. For placing icons I have used font-awesome library and put pre-built CSS codes inside divs.

Now using CSS I have placed all the elements in the right place, as you can see in the preview. With CSS I have done basic styling like margin, padding, position, size, color, etc. There I have used some google fonts for text and headings. For creating the little animation effect I have used CSS transition command.

The JavaScript part has the main feature of the program. I have created a whole calendar dynamically using JS which is based on the jQuery library. I have stored months in a variable and did many calculations. The whole calendar structure is created using the JavaScript DOM program. Later the calendar styled using CSS.

Left all other things you will understand after getting the codes, I can’t explain all in writing. For creating this program you have to create 3 files. First file for HTML, second for CSS, and the third file for JavaScript. Follow the steps to creating this program without any error.

index.html

Create an HTML file named ‘style.css‘ and put these codes given below.
