How can I implement dynamic fields in a React form?
You can use state to manage the fields and map over an array to render them dynamically. Would you like a code example?
Yes, please provide a code example.
Here's a simple example:
import React, { useState } from 'react';
const DynamicForm = () => {
const [fields, setFields] = useState(['']);
const handleAddField = () => {
setFields([...fields, '']);
};
const handleChange = (index, value) => {
const newFields = [...fields];
newFields[index] = value;
setFields(newFields);
};
return (
<div>
{fields.map((field, index) => (
<input
key={index}
value={field}
onChange={(e) => handleChange(index, e.target.value)}
/>
))}
<button onClick={handleAddField}>Add Field</button>
</div>
);
};
This will allow you to add input fields dynamically.
How do I handle form submission with these dynamic fields?
You can handle form submission by creating a function that collects the values from the fields and processes them. Would you like to see an example?
