菜单绑定渲染懒加载路由

/**
 * @interface 权限菜单定义
 * @description page 表示唯一路由，label 表示菜单中文名
 */
export
interface subMenus_t {
  label: string;
  page: string;
  icon?: string;
  subMenus?: subMenus_t[];
  menuApi?: any;
}


const menus: subMenus_t[];
// 之后赋值到menus 


// 一个渲染懒路由的示例
class A extends React.Component {


  render() {

    return (
      <>
      {
        dynamic_renders_routers(menus, {
          "page1": { // <Route /> 组件属性 和其它扩展属性
            "path": "page1", // 相对路由，跟随之前的路由
            "toload": [() => import("../page1.jsx"), { other: "附加属性" }]
          },
          "page2": {
            "path": "/page2", // 绝对路由
            "toload": () => import("../page2.jsx")
          },
          "*": {
            "path": "/404",
            "toload": () => import("../404.jsx")
          }
        }, {
          with_switch: {
            // <Switch />组件属性
          },
          with_Redirect: {
            // <Redirect />组件属性
          }
        })
      }
      </>
    )

  }
}

懒加载路由，单组件

import { LazyRoute } from "leadmap-web-front-end";

const Detail = () => import("../../common/work_order_detail/index.jsx");

function() {

  return (
    <Switch>
      <Route exact path={match.url} render={rest => <Ywgdgl {...rest} menu={menu} snapshot={ref.current} />} />
      <LazyRoute path={match.url + "/查看详情"} renderFactory="component" toload={[Detail, { aaa: 1022 }]} />
      <LazyRoute path={match.url + "/确认处理情况"} renderFactory="component" toload={[Detail, { aaa: 1022 }]} />
      <Redirect to={match.url} />
    </Switch>
  )
  
}
