### Input
|
|
|
|
Renders an `<input>` 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 `<input>` element.
|
|
* Render an `<input>` element with the appropriate attributes and use the `callback` function in the `onChange` event to pass the value of the input to the parent.
|
|
|
|
```jsx
|
|
function Input({ callback, type = 'text', disabled = false, readOnly = false, placeholder = '' }) {
|
|
return (
|
|
<input
|
|
type={type}
|
|
disabled={disabled}
|
|
readOnly={readOnly}
|
|
placeholder={placeholder}
|
|
onChange={({ target: { value } }) => callback(value)}
|
|
/>
|
|
);
|
|
}
|
|
```
|
|
|
|
```jsx
|
|
ReactDOM.render(
|
|
<Input type="text" placeholder="Insert some text here..." callback={val => console.log(val)} />,
|
|
document.getElementById('root')
|
|
);
|
|
```
