Handling Forms and User Input in React
<p>Forms are a essential part of many web applications. They allow users to interact with the application and provide data. In React, there are two ways to handle forms: controlled components and uncontrolled components.</p>
<p>Controlled components are the preferred way to handle forms in React. In a controlled component, the form data is stored in the component’s state. This means that the component is responsible for updating the form data whenever the user changes it.</p>
<p>To do this, you can use the useState hook to create a state variable for each form field. Then, you can bind the onChange event handler of the form field to a function that updates the state variable.</p>
<p>For example, the following code shows how to create a controlled component for a text input field:</p>
<pre>
import React, { useState } from "react";
function InputField() {
const [value, setValue] = useState("");
const handleChange = (e) => {
setValue(e.target.value);
};
return (
<input
type="text"
value={value}
onChange={handleChange}
/>
);
}
</pre>
<p>In this example, the value state variable stores the current value of the text input field. The handleChange function is called whenever the user changes the value of the text input field. This function updates the value state variable with the new value.</p>
