Renders a `<textarea>` element that uses a callback function to pass its value to the parent component.
|
|
|
|
- Use object destructuring to set defaults for certain attributes of the `<textarea>` element.
|
|
- Render a `<textarea>` element with the appropriate attributes and use the `callback` function in the `onChange` event to pass the value of the textarea to the parent.
|

|
```jsx
|
|
function TextArea({
|
|
callback,
|
|
cols = 20,
|
|
rows = 2,
|
|
disabled = false,
|
|
readOnly = false,
|
|
placeholder = ''
|
|
}) {
|
|
return (
|
|
<textarea
|
|
cols={cols}
|
|
rows={rows}
|
|
disabled={disabled}
|
|
readOnly={readOnly}
|
|
placeholder={placeholder}
|
|
onChange={({ target: { value } }) => callback(value)}
|
|
/>
|
|
);
|
|
}
|
|
```
|
|
|
|
```jsx
|
|
ReactDOM.render(
|
|
<TextArea placeholder="Insert some text here..." callback={val => console.log(val)} />,
|
|
document.getElementById('root')
|
|
);
