React Js Input url Validation
React Js Url Validation:In React.js, input type URL validation can be achieved using regular expressions (regex) and event handlers.
The first step is to create a regex pattern that matches a valid URL format. Then, an event handler is assigned to the input field to capture user input and check it against the regex pattern.
If the input matches the pattern, it is considered a valid URL; otherwise, an error message can be displayed to the user.
This approach ensures that the input adheres to the expected URL format and provides a seamless user experience by validating the input in real-time.

How can I perform URL validation using React.js?
The provided code is a React.js component that implements URL validation. It consists of a form with an input field for entering a URL.
The component uses React hooks (useState) to manage the state of the URL value, validation status, and error message. When the user enters a URL and submits the form, the handleSubmit function is called.
It uses a regular expression to validate the URL format. If the URL is valid, an alert is shown with the URL value. Otherwise, an error message is displayed.
The input field's className is dynamically updated based on the validity of the URL to apply styling.
