|
|
## When To Use
|
|
|
|
- When the system has more than two layers in a hierarchy.
|
|
- When you need to inform the user of where they are.

- When the user may need to navigate back to a higher level.

|
|
```jsx
|
|
import { Link } from 'react-router';
|
|
|
|
const routes = [
|
|
{
|
|
path: 'index',
|
|
breadcrumbName: 'home',
|
|
},
|
|
{
|
|
path: 'first',
|
|
breadcrumbName: 'first',
|
|
children: [
|
|
{
|
|
path: '/general',
|
|
breadcrumbName: 'General',
|
|
},
|
|
{
|
|
path: '/layout',
|
|
breadcrumbName: 'Layout',
|
|
},
|
|
{
|
|
path: '/navigation',
|
|
breadcrumbName: 'Navigation',
|
|
},
|
|
],
|
|
},
|
|
{
|
|
path: 'second',
|
|
breadcrumbName: 'second',
|
|
},
|
|
];
|
|
function itemRender(route, params, routes, paths) {
|
|
const last = routes.indexOf(route) === routes.length - 1;
|
|
return last ? (
|
|
<span>{route.breadcrumbName}</span>
|
|
) : (
|
|
<Link to={paths.join('/')}>{route.breadcrumbName}</Link>
|
|
);
|
|
}
|
|
|
