### TextArea
|
|
|
|
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')
|
|
);
|
|
```
