感谢无私的程序员们分享

我们边看效果边看代码

项目运行出来的效果



先看Home页面

轮播

//src\pages\Home\model\Carousel.js
import React, { Component } from 'react'
import { Carousel } from 'antd-mobile'
import img from '@/images/banner/1.jpg'
import img2 from '@/images/banner/2.jpg'
import img3 from '@/images/banner/3.jpg'

class app extends Component {
  state = {
    data: ['1', '2', '3'],
    imgHeight: 176,
  }

  componentDidMount() {
    // simulate img loading
    setTimeout(() => {
      this.setState({
        data: [img, img2, img3],
      });
    }, 100);
  }

  render() {
    return (
      <Carousel
        autoplay={false}
        infinite
        beforeChange={(from, to) => console.log(`slide from ${from} to ${to}`)}
        afterChange={index => console.log('slide to', index)}
      >
        {this.state.data.map((val, index) => (
          <a
            key={index}
            style={{ display: 'inline-block', width: '100%', height: this.state.imgHeight }}
          >
            <img
              src={val}
              alt="val"
              style={{ width: '100%', verticalAlign: 'top', height: this.state.imgHeight }}
              onLoad={() => {
                // fire window resize event to change height
                // 若用非手机模式打开，imgheight会因为整个浏览器的长度100%自适应造成100%全屏，手机模式加载则没影响
                window.dispatchEvent(new Event('resize'));
                this.setState({ imgHeight: 'auto' })
              }}
            />
          </a>
        ))}
      </Carousel>
    )
  }
}

export default app

这里也是封装成组件做的

//src\components\Card\index.js
import React, { Component } from 'react'
import PropTypes from 'prop-types'
import style from './index.less'

class app extends Component {
  PropTypes={
    list: PropTypes.array,
    className:PropTypes.string,
  }
  static defaultProps ={
    list :[],
  }

  state = {
  }
componentDidMount(){
}
componentWillReceiveProps(nextProps){
}

close=()=>{
  this.setState({open:false})
  this.props.onClose()
}

  render() {
    const {list,className} = this.props
      return (
        <div className={`${style["card-wrap"]} ${className}`}>
          {
          list.map((x,index)=>(
            <div className={style.card} key={index}>
              <div className="card-img">
                <img src={x.src} alt="" />
              </div>
              <div className="title">
                {x.title}
              </div>
            </div>
          ))
        }
        </div>
      )
  }
}

export default app

看整体的代码是这个

//src\pages\Home\index.js
import React, { Component } from 'react'
import { InputItem, Button, WhiteSpace, WingBlank, NoticeBar } from 'antd-mobile'
//轮播组件
import Carousel from './model/Carousel'
import Card from '@/components/Card'
import img from '@/images/moon.png'

class app extends Component {
  state = {
    title: '欢迎来到叭哩叭哩,github-https://github.com/1067011734/balibali！！！！'
  }
  cardList = [
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
    { title: '团员中秋', src: img },
  ]
  render() {
    const { title } = this.state
    return (
      <div className="page">
        <NoticeBar marqueeProps={{ loop: true, style: { padding: '0 7.5px' } }}>
          {title}
        </NoticeBar>
        <Carousel />
        <Card list={this.cardList}/>
      </div>
    )
  }
}

export default app

在index.js中我们引用app

//src\pages\index.js
import React, { Component } from 'react'
import { connect } from 'dva'
import Transiton from '@/components/Transition'
import '@/styles/base.less'

class app extends Component {
  state = {
  }

  componentDidMount(){

  }

  render() {
    return (
      <Transiton {...this.props}>
        {this.props.children}
      </Transiton>
    )
  }
}

export default app

//src\components\Transition\index.js
import React, { Component } from 'react'
import PropTypes from 'prop-types'
import ReactCSSTransitionGroup from 'react-addons-css-transition-group'
import StaticContainer from 'react-static-container'
import style from './index.less'

class app extends Component {
  PropTypes={
    open: PropTypes.bool,
    onClose: PropTypes.func,
  }

  state = {
    previousPathname:null,
  }

componentWillMount() {
  document.body.style.margin = "0px";
  // 这是防止页面被拖拽
  document.body.addEventListener('touchmove', (ev) => {
    ev.preventDefault();
  });
}

componentWillReceiveProps(nextProps, nextContext) {
  if (nextProps.location.pathname !== this.props.location.pathname) {
      this.setState({ previousPathname: this.props.location.pathname })
  }
}

componentDidUpdate() {
    if (this.state.previousPathname) {
        this.setState({ previousPathname: null })
    }
}

  render() {
    const {location,children,history} =this.props
    const {action} =history
    //goback:pop,push:push
    const className = action==='POP'?'translation-arrow-right':'translation-arrow-left'
    // const className = 'translation-arrow-left'
    const {pathname} =location
    const key = (pathname!=="/user")?'':"pathname"
      return (
        <ReactCSSTransitionGroup
          component="div"
          className={`translation-wrap ${className}`}
          transitionName="translation"
          transitionEnterTimeout={300}
          transitionLeaveTimeout={300}
          // transitionLeave={false}
        >
          {/* 用key控制滑动权限----- 苍天啊 */}
          <div key={key} className={`${pathname} translation-content`}>
            {children}
          </div>
        </ReactCSSTransitionGroup>
      )
  }
}

export default app

其实我很好奇，下面的切换页面在哪里

下面的是login页面

//src\pages\Login.js
import React, { Component } from 'react'
import { InputItem, Button, WhiteSpace, Toast } from 'antd-mobile'
import { createForm } from 'rc-form'
import { connect } from 'dva'

import avataSrc from '@/images/icon/avatar.png'
import loginUserSrc from '@/images/icon/login_user.png'
import loginPassSrc from '@/images/icon/login_pass.png'
@createForm()
@connect(({ login, loading }) => ({
  login,
  submitting: loading.effects['login/login'],
}))
class app extends Component {
  state = {
  }

  submit = () => {
    const { getFieldProps, getFieldError } = this.props.form
    this.props.form.validateFields((error, values) => {
      if (error) {
        const msg = `请输入${getFieldError('user') || ''}${getFieldError('password') || ''}`
        Toast.info(msg, 1);
        return
      }
      // this.props.history.push({ pathname: '/home' })
      const { dispatch } = this.props
      dispatch({
          type: 'common/login',
          payload: {
            ...values,
          },
        })
    })
  }
  normalize = (val, prev) => {
    if (!loginReg.test(val)) {
      Toast.info('不能包含中文和大写', 1);
      return prev
    }
    return val
  }
  render() {
    let errors
    const { getFieldProps } = this.props.form
    return (
      <div className={`page ${style.login}`}>
        <div className={`${style["page-header"]}`}>
          <label>进入叭哩叭哩</label><img src={avataSrc} alt=""/>
        </div>
        <InputItem
          type="text"
          placeholder="账号为admin"
          maxLength="10"

          clear
          {...getFieldProps('user', {
            rules: [{ required: true, message: '账号', }],
            normalize: this.normalize,
          })}
        >
        <img src={loginUserSrc} className='icon' />
            </InputItem>
        <InputItem
          type="password"
          placeholder="密码为admin"
          maxLength="10"
          clear
          {...getFieldProps('password', {
            rules: [{ required: true, message: '密码', }],
            normalize: this.normalize
          })}
        >
        <img src={loginPassSrc} className='icon' />
            </InputItem>
        <WhiteSpace size="xl"/>
        <WhiteSpace size="xl"/>

路由也是会骗人的
