react-问卷星项目（6）

实战

React常用UI组件库

Ant Design国内最常用组件库，稳定，强大
Material UI国外流行
TailWind UI 国外流行，收费

Ant Design

这一章基本内容就是使用UI重构页面，也没有什么知识点，直接上代码

下载

npm install antd --save

安装icon组件包

npm install @ant-design/icons --save

router/index.tsx

// 导出常用路由
export const LOGIN_PATHNAME = "/login";
export const REGISTER_PATHNAME = "/register";
export const HOME_PATHNAME = "/home";
export const MANAGER_INDEX_PATHNAME = "/manager/list";

大致更新的顺序为组件 -> 布局 -> 页面

组件当前结构如下

Logo.tsx

TypeScript 复制代码

import React, { FC } from "react";
import { Space, Typography } from "antd";
import { FormOutlined } from "@ant-design/icons";
import { Link } from "react-router-dom";
import styled from "./Logo.module.scss";
const { Title } = Typography;

const Logo: FC = () => {
  return (
    <div className={styled.container}>
      <Link to="/">
        <Space>
          <Title>
            <FormOutlined />
          </Title>
          <Title>小木问卷</Title>
        </Space>
      </Link>
    </div>
  );
};
export default Logo;

Logo.module.scss

TypeScript 复制代码

.container{

QuestionCard.module.scss

TypeScript 复制代码

.container{

  padding: 12px;
  border-radius: 3px;
  background-color: white;

  &:hover{

UserInfo.tsx

TypeScript 复制代码

import React, { FC } from "react";

import { LOGIN_PATHNAME } from "../router";

const UserInfo: FC = () => {
  return (
    <>
      <Link to={LOGIN_PATHNAME}>登录</Link>
    </>
  );
};
export default UserInfo;

布局这一块的样式我和视频里老师的写法不一致，能实现效果就行

MainLayout.tsx

css 复制代码

import React, { FC } from "react";
import { Outlet } from "react-router-dom";
import { Layout } from "antd";
import styled from "./MainLayout.module.scss";
import Logo from "../components/Logo";
import UserInfo from "../components/UserInfo";

const { Header, Content, Footer } = Layout;

const MainLayout: FC = () => {
  return (
    <Layout>
      <Header className={styled.header}>
        <div className={styled.left}>
          <Logo />
        </div>
        <div className={styled.right}>
          <UserInfo />
        </div>
      </Header>
      <Layout className={styled.main}>
        <Content>
          <Outlet />
        </Content>
      </Layout>
      {/* <Content className={styled.main}>
        <Outlet />
      </Content> */}
      <Footer className={styled.footer}>
        小木问卷 &copy; 2023-present. Created by 双
      </Footer>
    </Layout>
  );
};

export default MainLayout;

MainLayout.module.scss

css 复制代码

  display: flex;
  justify-content: space-between;
  align-items: center;
  font-size: 20px;

  .left{
    float: left;

  min-height: calc(100vh - 64px - 71px);
}

.footer{

  border-top: 1px solid #e8e8e8;
}

ManagerLayout.tsx

css 复制代码

import React, { FC } from "react";
import { Outlet, useNavigate, useLocation } from "react-router-dom";
import styled from "./MangerLayout.module.scss";

import { Button, Space, Divider } from "antd";
import {

  console.log(pathname);

  return (

      <div className={styled.left}>
        <Space direction="vertical">
          <Button type="primary" size="large" icon={<PlusOutlined />}>
            新建问卷
          </Button>
          <Divider style={{ border: "none" }} />
          <Button
            type={pathname.startsWith("/manager/list") ? "default" : "text"}
            size="large"
            icon={<BarsOutlined />}
            onClick={() => nav("/manager/list")}
          >

          </Button>
          <Button

            onClick={() => nav("/manager/trash")}
          >
            回收站
          </Button>
        </Space>
      </div>
      <div className={styled.right}>
        <Outlet />
      </div>
    </div>
  );
};
export default MangerLayout;

ManagerLayout.module.scss

css 复制代码

.container{
  display: flex;
  padding: 24px 0;
  width: 1200px;
  margin: 0 auto; // 水平居中
  
  .left{
    width: 120px;

  }
  .right{
    flex: 1;
    margin-left: 60px;

  }

}

接下来就是零散的各个页面的布局，下面的图片是管理问卷的大概样式设置，可以按照登录时看到的页面顺序进行样式更新，比如Home -> List -> Star -> Trash，大部分从antd导入的都是文档中能看到的组件，直接用了看效果就行，想更进一步了解的可以去翻阅相关的文档

Home.tsx

TypeScript 复制代码

// 首页
import React, { FC } from "react";
import { useNavigate, Link } from "react-router-dom";
import { Button, Typography } from "antd";
// router中导出的设置好的路径
import { MANAGER_INDEX_PATHNAME } from "../router";
import styled from "./Home.module.scss";

// Typography可以理解为文章组件，可以分解出标题段落等，经常使用

const { Title, Paragraph } = Typography;

const Home: FC = () => {
  const nav = useNavigate();

  // function clickHandler() {
  //   nav({
  //     pathname: "/login", // 路径
  //     search: "b=21", // 路径附加参数，类似get
  //   });
  // }

  return (
    <div className={styled.contain}>
      <div className={styled.info}>
        <Title>问卷调查｜在线投票</Title>
        <Paragraph>已累计创建问卷100份，发布问卷90份，收到答卷989份</Paragraph>
        <div>
          <Button type="primary" onClick={() => nav(MANAGER_INDEX_PATHNAME)}>
            开始使用
          </Button>
        </div>
      </div>
    </div>
  );
};
export default Home;

Home.module.scss

其中background-image就是一个渐变的css设置，颜色可以参考渐变颜色，直接复制即可

css 复制代码

.contain{
  background-color: aqua;
  height: 100vh;
  width: 100vw;
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  background-image: linear-gradient(to top, #5ee7df 0%, #b490ca 100%);
  // background-image: linear-gradient(to top, #9890e3 0%, #b1f4cf 100%);
  
  .info{
    text-align: center;

    button{
      height: 60px;
      font-size: 24px;
    }
    
  }
}

Manager/list.tsx

注意Home界面的跳转导入的路径就是这个list，可以自己命名

css 复制代码

import React, { FC, useState } from "react";
import { useSearchParams } from "react-router-dom";
import QuestionCard from "../../components/QuestionCard";
import styled from "./Common.module.scss";
import { Typography } from "antd";
import { useTitle } from "ahooks";

const { Title } = Typography;

const rawQuestionList = [
  {
    _id: "q1",
    title: "问卷1",
    isPublished: true,
    isStar: false,
    answerCount: 5,
    createAt: "3月10日 13:23",
  },
  {
    _id: "q2",
    title: "问卷2",
    isPublished: false,
    isStar: true,
    answerCount: 15,

    isPublished: false,
    isStar: false,
    answerCount: 98,
    createAt: "3月23日 13:23",
  },
];

const List: FC = () => {
  // const [searchParams] = useSearchParams();
  // console.log("keyword", searchParams.get("keyword"));

  useTitle("小木问卷-我的问卷");

  const [questionList, setQuestionList] = useState(rawQuestionList);
  return (
    <>
      <div className={styled.header}>
        <div className={styled.left}>
            // level 3表示h3
          <Title level={3}>我的问卷</Title>
        </div>
        <div className={styled.right}>搜索</div>
      </div>
      <div className={styled.content}>
        {/* {问卷列表} */}
        {questionList.length > 0 &&
          questionList.map((q) => {
            const { _id } = q;
            return <QuestionCard key={_id} {...q} />;
          })}
      </div>
      <div className={styled.footer}>loadMore 上划加载更多</div>
    </>
  );
};

export default List;
