前面几篇文章将项目配置以及部分功能实现,这篇主要把前端的路由跳转功能实现一下,话不多说,直接开始盘

说到路由,菜单栏是必不可少的。

  • 首先在心中构思一下数据管理的结构,管理系统一般是顶部菜单和侧边菜单,这里我们用侧边栏进行路由

  • 来做基本的架子,在antd找到layout布局

  • 将四个部分分别做成组件,放到component中,头和脚内容不多,直接跳过,开始实现侧边栏功能,直接复制一下官方的组件,在上头加个logo就好了,但是由于侧边栏需要实现路由功能,所以将其配置数据剥离出来,新建menuList.js文件,放在config文件夹中(当然,也可以添加图标,这里主要因为懒(◍´꒳`◍),所以没加)
export default class MenuList {
  static leftMenu = [
    {
      name: "商品管理",
      list: [
        { name: "查找商品", route: "/admin/findshop" },
        { name: "新增商品", route: "/admin/addshop" },
        { name: "修改商品", route: "/admin/updatashop" }
      ]
    },
    {
      name: "用户管理",
      list: [
        { name: "用户列表", route: "/admin/userlist" },
      ]
    }
  ];
}
  • 在侧边栏组件中引入menuList并开始实现界面
import React from "react";
import "./left.less";
import { Menu } from "antd";
import { Link } from "react-router-dom";
import MenuData from "../../config/menuList";

const { SubMenu } = Menu;
export default class Left extends React.Component {
  createMenu(data) {
    return data.map((item) => {
      if (item.list) {
        //递归生成子项
        return (
          <SubMenu key={item.name} title={item.name}>
            {this.createMenu(item.list)}
          </SubMenu>
        );
      } else {
        return (
          <Menu.Item key={item.name} title={item.name}>
            <Link to={item.route}>{item.name}</Link>
          </Menu.Item>
        );
      }
    });
  }
  render() {
    return (
      <div className="leftBox">
        <Menu
          defaultSelectedKeys={["1"]}
          defaultOpenKeys={["sub1"]}
          mode="inline"
          theme="dark"
        >
          {this.createMenu(MenuData.leftMenu)}
        </Menu>
      </div>
    );
  }
}

  • 侧边栏实现后,我们需要配置一下路由,和侧边栏相似,新建routeList用于配置路由数据,将所有界面引入到routeList(需要新建所有的界面,在render中随便返回一个标识就好了)
import FindShop from "../page/shop/findItem/find";
import AddShop from "../page/shop/addItem/add";
import UpdataShop from "../page/shop/findItem/find";
import UserList from "../page/user/userList/userList";
export default class RouteList {
  static leftMenu = [
    { name: "查找商品", route: "/admin/findshop", comp: FindShop },
    { name: "新增商品", route: "/admin/addshop", comp: AddShop },
    { name: "修改商品", route: "/admin/updatashop", comp: UpdataShop },
    { name: "用户列表", route: "/admin/userlist", comp: UserList },
  ];
}
  • 接着是构建路由
import React from "react";
import {
  HashRouter as Router,
  Route,
  Switch,
  Redirect
} from "react-router-dom";
import RouteList from "../config/routeList";
import Login from "../page/login/login";
import Home from "../page/home/home";
import NotFind from "../page/errpage/404";
export default class RoutrModel extends React.Component {
  render() {
    return (
      <Router>
        <Switch>
          <Route exact path="/">
            <Redirect to="login"></Redirect>
          </Route>
          <Route path="/login" component={Login}></Route>
          <Route exact path="/admin">
            <Redirect to="/admin/findshop"></Redirect>
          </Route>
          <Route
            path="/admin"
            render={props => {
              return (
                <Home {...props}>
                  <Switch>
                    {this.createRoute()}
                    <Route component={NotFind}></Route>
                  </Switch>
                </Home>
              );
            }}
          ></Route>
          <Route component={NotFind}></Route>
        </Switch>
      </Router>
    );
  }
  createRoute = props => {
    return RouteList.leftMenu.map(item => {
      return (
        <Route path={item.route} component={item.comp} key={item.route}></Route>
      );
    });
  };
}
  • 在App.js中引入route组件,将之前固定的login界面替换成route组件,达到以下效果

import React from "react";
import Route from "./route/route";
function App() {
  return (
    <div className="App">
      <Route></Route>
    </div>
  );
}
export default App;

总结 

组件化开发的核心是组件复用,同一个组件配置项和传递参数不同,其效果功能也不同
