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

|
||
import { Link } from 'react-router';
|
||
|
||
const routes = [{
|
||
path: 'index',
|
||
breadcrumbName: 'home'
|
||
}, {
|
||
path: 'first',
|
||
breadcrumbName: 'first'
|
||
}, {
|
||
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>;
|
||
}
|
||
|
||
return <Breadcrumb itemRender={itemRender} routes={routes} />;
