How To Change Date Format Received From Input Field Using JavaScript

In today's guide, we will address a common challenge faced by web developers: changing the date format received from an input field using JavaScript. Many applications require specific formats for date values, especially when dynamically generating image URLs based on user input. In this article, we'll guide you through the solution, making just a few minor adjustments to your JavaScript code.

The Challenge

Imagine you have an HTML form that allows users to select a city and a date. The user input might be in the format YYYY-MM-DD (e.g., 2023-01-13), but you want to convert it to DD-MM-YYYY (i.e., 13-01-2023) for constructing dynamic image source URLs. This is the core of the problem we are going to solve.

Solution Overview

To solve this issue, we need to follow these steps:

Capture the date input value from the user.

Split the date string into its components (year, month, day).

Reverse the order of the components to get the desired format.

Construct the new date string and use it as part of the image URLs.

Step-by-Step Breakdown

Step 1: HTML Form Setup
