<Alert message="在 4.24.0 版本后,我们提供了 <Breadcrumb.Item menu={{ items: [...] }}> 的简写方式,有更好的性能和更方便的数据组织方式,开发者不再需要自行拼接 JSX。同时我们废弃了原先的写法,你还是可以在 4.x 继续使用,但会在控制台看到警告,并会在 5.0 后移除。"></Alert>

### 和 browserHistory 配合
|
|
|
|
|
|
|
|
|
|
和 react-router 一起使用时,默认生成的 url 路径是带有 `#` 的,如果和 browserHistory 一起使用的话,你可以使用 `itemRender` 属性定义面包屑链接。
|
|
|
|
|
|
|
|
|
|
```jsx
|
|
|
|
|
import { Link } from 'react-router';
|
|
|
|
|
|
2019-05-06 12:04:39 +08:00
|
|
|
|
const routes = [
|
|
|
|
|
{
|
|
|
|
|
path: 'index',
|
|
|
|
|
breadcrumbName: 'home',
|
|
|
|
|
},
|
|
|
|
|
{
|
|
|

|
|

},

|
{

|
|
|
|
|
) : (

<Link to={paths.join('/')}>{route.breadcrumbName}</Link>
|
|
|
|
|
);
