显示当前页面在系统层级结构中的位置，并能向上返回。
|
||
|
||
## 何时使用
|
||
|
||
- 当系统拥有超过两级以上的层级结构时；
|
||
- 当需要告知用户『你在哪里』时；
|
||
- 当需要向上导航的功能时。
|
||
|
||
```jsx
|
||
// >=5.3.0 可用，推荐的写法 ✅
|
||
return <Breadcrumb items={[{ title: 'sample' }]} />;
|
||
|
||
// <5.3.0 可用，>=5.3.0 时不推荐 🙅🏻♀️
|
||
return (
|
||
<Breadcrumb>
|
||
<Breadcrumb.Item>sample</Breadcrumb.Item>
|
||
</Breadcrumb>
|
||
);
|
||
|
||
// 或
|
||
|
||
return <Breadcrumb routes={[{ breadcrumbName: 'sample' }]} />;
|
||
```

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