How do I handle form submission in React?
In React, you can handle form submission by using the onSubmit event handler. You typically define a function that processes the form data.
Can you show me a simple example?
Sure! Here's a basic example:
function MyForm() {
const handleSubmit = (event) => {
event.preventDefault(); // Prevent the default form submission
const formData = new FormData(event.target);
console.log('Form data:', Object.fromEntries(formData));
};
return (
<form onSubmit={handleSubmit}>
<input type="text" name="name" placeholder="Your Name" required />
<button type="submit">Submit</button>
</form>
);
}
What if I want to validate the form before submission?
You can add validation logic inside the handleSubmit
function before processing the form data. For example, check if fields are filled out correctly.
