react-添加页面容器

效果

在这里插入图片描述

1. index.ts

import style from './index.less'
import { history } from 'umi';

  children: any
  route: any
  location: any

 * 路由信息
 */
interface RouteInfo {
  // 路由路径
  path: string,

  // 路由名称
  name: string,

}

/**
 * 页面容器
 */
export default (props: Props) => {
  // 全部路由数据
  const [routeList, setRouteList] = useState<RouteInfo[]>([])
  // 当前选中的路由
  const [checkRouteList, setCheckRouteList] = useState<RouteInfo[]>([])
  // 当前选中的路径
  const [currentPath, setCurrentPath] = useState<string>('')

  // 获取路由全部数据
  useEffect(() => {
    let routeList: any = []
    recurGetRoutes(props.route, routeList)
    setRouteList(routeList)
  }, [])
  let pathName = props.location.pathname
  /**
   * 当路由数据加载完毕后,如果当前路径和当前所在路由不同,则需要判断是否已经push到选中的路由中。
   * 如果已经选中则不需要重复push。
   */
  if (routeList?.length) {
    if (currentPath !== pathName) {
      setCurrentPath(pathName)
      if (!checkRouteList.some(item => item.path === pathName)) {
        let currentRoutes: RouteInfo[] = routeList.filter(item => item.path === pathName)
        if (currentRoutes?.length) {
          checkRouteList.push(currentRoutes[0])
        }
      }
    }
  }

  return <>
