Form validation is a process of checking the correctness of the information entered by the user. The form would send an alert message to the user if they entered some invalid information (or something different than the typical input; else, it would proceed with the registration or signup process.
We can validate the form in reactjs by using the “handleChange” function. Whenever users enter some input element, the “onChange” event handler function will create an event object and pass it to the handleChange function.
Let us understand this by taking a real-life example. Suppose we have a form with five inputs:
Now, we can create a function to check the maximum length for the name, phone number, or the correct email format. Also, we can create a function that will be called if any invalid information is found and will throw an error message.
Here is an example of how to create form validation using ReactJS;
