React 折腾记 - (9) 基于Antd+react-router-breadcrumbs-hoc封装一个小巧的面包屑组件

React 16.4 / UmiJS 2.2 / Antd 3.x / react-router-breadcrumbs-hoc 2.x : API简洁易懂

效果图

• 非 antd 风格

• antd 风格

源码及实现

暴露的 props :

• data : 面包屑的映射关系,数组( react-router-breadcrumbs-hoc 要求的那种)

比如 : const routes = [{ path: '/', breadcrumb: '首页' }] ;

若是不传递的情况下,高阶组件( react-router-breadcrumbs-hoc )会自动获取路径名字为面包屑的名字

Breakcrumbs

import Link from 'umi/link';
import withBreadcrumbs from 'react-router-breadcrumbs-hoc';
import { Breadcrumb, Badge, Icon } from 'antd';

// 更多配置请移步 https://github.com/icd2k3/react-router-breadcrumbs-hoc
const routes = [{ path: '/', breadcrumb: '首页' }];

const Breadcrumbs = ({ data }) => {
  if (data && Array.isArray(data)) {
    const AntdBreadcrumb = withBreadcrumbs(data)(({ breadcrumbs }) => {
      return (
        <Breadcrumb separator={<Icon type="double-right" />} classNames="spread">
          {breadcrumbs.map((breadcrumb, index) => (
            <Breadcrumb.Item key={breadcrumb.key}>
              {breadcrumbs.length - 1 === index ? (
                <Badge status="processing" text={breadcrumb} />
              ) : (
                <Link
                  to={{
                    pathname: breadcrumb.props.match.url,
                    state: breadcrumb.props.match.params ? breadcrumb.props.match.params : {},
                    query: breadcrumb.props.location.query ? breadcrumb.props.location.query : {},
                  }}
                >
                  {breadcrumb}
                </Link>
              )}
            </Breadcrumb.Item>
          ))}
        </Breadcrumb>
      );
    });
    return <AntdBreadcrumb />;
  }
  const DefaultBreadcrumb = withBreadcrumbs(routes)(({ breadcrumbs }) => (
    <div>
      {breadcrumbs.map((breadcrumb, index) => (
        <span key={breadcrumb.key}>
          <Link
            to={{
              pathname: breadcrumb.props.match.url,
              state: breadcrumb.props.match.params ? breadcrumb.props.match.params : {},
              query: breadcrumb.props.location.query ? breadcrumb.props.location.query : {},
            }}
          >
            {breadcrumb}
          </Link>
          {index < breadcrumbs.length - 1 && <i> / </i>}
        </span>
      ))}
    </div>
  ));
  return <DefaultBreadcrumb />;
};

export default Breadcrumbs;
