React Forms - Textarea
Textarea
The textarea element in React is slightly different from ordinary HTML.
In HTML the value of a textarea is the text between the start tag
<textarea>
and the end tag </textarea>.
<textarea>
Content of the textarea.
</textarea>In React the value of a textarea is placed in a value attribute, just like with the input element.
We'll use the useState Hook to manage the value of the textarea:
Example:
React uses the value attribute to control the textarea:
import { createRoot } from 'react-dom/client'
import { useState } from 'react'
function MyForm() {
const [mytxt, setMytxt] = useState("");
function handleChange(e) {
setMytxt(e.target.value);
}
return (
<form>
<label>Write here:
<textarea
value={mytxt}
onChange={handleChange}
/>
</label>
<p>Current value: {mytxt}</p>
</form>
)
}
createRoot(document.getElementById('root')).render(
<MyForm />
);By making these changes to the <textarea> element,
React is able to handle it as any other input element.
