/**
|
|
## Render props
|
|
|
|
To use the `<InView>` component, you pass it a function. It will be called
|
|
whenever the state changes, with the new value of `inView`. In addition to the
|
|
`inView` prop, children also receive a `ref` that should be set on the
|
|
containing DOM element. This is the element that the IntersectionObserver will
|
|
monitor.
|
|
|
|
If you need it, you can also access the
|
|
[`IntersectionObserverEntry`](https://developer.mozilla.org/en-US/docs/Web/API/IntersectionObserverEntry)
|
|
on `entry`, giving you access to all the details about the current intersection
|
|
state.
|
|
|
|
```jsx
|
|
import { InView } from 'react-intersection-observer';
|
|
|
|
const Component = () => (
|
|
<InView>
|
|
{({ inView, ref, entry }) => (
|
|
<div ref={ref}>
|
|
<h2>{`Header inside viewport ${inView}.`}</h2>
|
|
</div>
|
|
)}
|
|
</InView>
|
|
);
|
|
|
|
export default Component;
|
|
```
|
|
|
|
## Plain children
|
|
|
|
You can pass any element to the `<InView />`, and it will handle creating the
|
|
wrapping DOM element. Add a handler to the `onChange` method, and control the
|
|
state in your own component. Any extra props you add to `<InView>` will be
|
|
passed to the HTML element, allowing you set the `className`, `style`, etc.
|
|
|
|
```jsx
|
|
import { InView } from 'react-intersection-observer';
|
|
|
|
const Component = () => (
|
|
<InView as="div" onChange={(inView, entry) => console.log('Inview:', inView)}>
|
|
<h2>Plain children are always rendered. Use onChange to monitor state.</h2>
|
|
</InView>
|
|
);
|
|
|
|
export default Component;
|
|
```
