一、按鈕Button

• pages->ui->button.js：對應路由/admin/ui/buttons

import React from 'react';
import {Card, Button, Radio} from 'antd'
import './ui.less'

class Buttons extends React.Component{

  state = {
      loading: true,
      size: 'default'
  }  
   
  handleCloseLoading = () =>{
      this.setState({
          loading: false
      })
  } 

  handleChange = (e) => {
      this.setState({
          size: e.target.value
      })
  }

  render(){
      return(
          <div>
              <Card title="基礎按鈕" className="card-wrap">
                    <Button type="primary">提交</Button>  
                    <Button>普通</Button>
                    <Button type="dashed">非重要功能</Button>  
                    <Button type="danger">刪除</Button>
                    <Button disabled>禁用</Button>             
              </Card>
              <Card title="圖形按鈕" className="card-wrap">
                    <Button icon="plus">創建</Button>  
                    <Button icon="edit">編輯</Button>
                    <Button icon="delete">刪除</Button>  
                    <Button shape="circle" icon="search"></Button>
                    <Button type="primary" icon="search">搜索</Button>
                    <Button type="primary" icon="download">下載</Button>               
              </Card>
              <Card title="Loading按鈕" className="card-wrap">
                    <Button type="primary" loading={this.state.loading}>確定</Button>  
                    <Button type="primary" shape="circle" loading={this.state.loading}></Button>
                    <Button loading={this.state.loading} >點擊加載</Button>  
                    <Button shape="circle" loading={this.state.loading}></Button>
                    <Button type="primary" onClick={this.handleCloseLoading}>關閉</Button>               
              </Card>
              <Card title="按鈕組" style={{marginBottom:10}}>
                    <Button.Group>
                        <Button type="primary" icon="left">返回</Button>
                        <Button type="primary" icon="right">前進</Button>
                    </Button.Group>              
              </Card>
              <Card title="按鈕尺寸" className="card-wrap">
                    <Radio.Group size={this.state.size} onChange={this.handleChange}>
                        <Radio value="small">小</Radio>
                        <Radio value="default">中</Radio>
                        <Radio value="large">大</Radio>
                    </Radio.Group>
                    <Button type="primary" size={this.state.size}>Imooc</Button>  
                    <Button size={this.state.size}>Imooc</Button>
                    <Button type="dashed" size={this.state.size}>Imooc</Button>  
                    <Button type="danger" size={this.state.size}>Imooc</Button>               
              </Card>
          </div>
      );
  }
}
export default Buttons;

• Button組件

1. type屬性 ：表示按鈕類型
2. disable屬性：表示禁用按鈕
3. icon屬性：表示按鈕圖標樣式   icon圖標集合
4. shape屬性：表示按鈕形狀（circle表示圓形）
5. loading屬性：為{true}表示加載中（此時按鈕不能點擊）
6. size屬性：表示組件大小
7. Button.Group按鈕組組件：表示包含的Button組件是一個組

• Card組件

1. title屬性用於標注卡片上方標題

• Radio組件

1. 外部需要用Radio.Group組件包裹
2. 通過外部組件對象可以獲得內部Radio組件的value值(通過e.target.value)

• 坑：Route頁面內容超過屏幕時，會出現滾動條，左側下方出現空白區
• 解決：ui.less中給main添加overflow:auto; 當渲染頁面高度超過當前屏幕時，自動滾動

   

二、彈框Modal

• pages->ui->modals：對應路由/admin/ui/modals

import React from 'react';
import {Card, Button, Modal} from 'antd'
import './ui.less'

export default class Buttons extends React.Component{
    state = {
       showModal1: false,
       showModal2: false,
       showModal3: false,
       showModal4: false
    }
    handleOpen = (type) => {
        this.setState({
           [type]: true
        }) 
    }
    handleConfirm = (type) => {
        Modal[type]({
            title: '確認？',
            content:'你確認你學會了React了嗎？',
            onOk() {
                console.log('ok')
            },
            onCancel() {
                console.log('Cancel')
            }
        })
    }
    render(){
        return (
            <div>
                <Card title="基礎模態框" className="card-wrap">
                    <Button type="primary" onClick={() => this.handleOpen('showModal1')}>Open</Button>
                    <Button type="primary" onClick={() => this.handleOpen('showModal2')}>自定義頁腳</Button>
                    <Button type="primary" onClick={() => this.handleOpen('showModal3')}>頂部20px頁腳</Button>
                    <Button type="primary" onClick={() => this.handleOpen('showModal4')}>水平垂直居中</Button>
                </Card>
                <Card title="信息確認框" className="card-wrap">
                    <Button type="primary" onClick={() => this.handleConfirm('confirm')}>Confirm</Button>
                    <Button type="primary" onClick={() => this.handleConfirm('info')}>Info</Button>
                    <Button type="primary" onClick={() => this.handleConfirm('success')}>Success</Button>
                    <Button type="primary" onClick={() => this.handleConfirm('warning')}>Warning</Button>
                </Card>
                <Modal 
                    title="React" 
                    visible={this.state.showModal1} 
                    onCancel={() => {
                        this.setState({
                            showModal1: false
                        })
                    }}>
                    <p>歡迎使用柳柳版彈框</p>
                </Modal>
                <Modal 
                    title="React" 
                    visible={this.state.showModal2} 
                    okText="好的"
                    cancelText="算了"
                    onCancel={() => {
                        this.setState({
                            showModal2: false
                        })
                    }}>
                    <p>歡迎使用柳柳版彈框</p>
                </Modal>
                <Modal 
                    title="React" 
                    style={{top:20}}
                    visible={this.state.showModal3} 
                    onCancel={() => {
                        this.setState({
                            showModal3: false
                        })
                    }}>
                    <p>歡迎使用柳柳版彈框</p>
                </Modal>
                <Modal 
                    title="React" 
                    wrapClassName="vertical-center-modal"
                    visible={this.state.showModal4} 
                    onCancel={() => {
                        this.setState({
                            showModal4: false
                        })
                    }}>
                    <p>歡迎使用柳柳版彈框</p>
                </Modal>
                
            </div>
        )
    }
}

• Modal組件

1. title屬性：作為標題顯示
2. visible屬性：參數為{true|false}，為true則顯示，false則不顯示
3. onCancel屬性：值為一個函數，執行當點擊模態框的×或cancel選項時執行的方法
4. Model內部填寫的內容將作為模態框的正文內容

• Model自定義頁腳實現方式

1. visible屬性：{true}或{false}實現是否顯示
2. okText屬性：設置OK選項的顯示內容
3. cancelText屬性：設置Cancel選項顯示內容

• Model頂部20px彈框實現方式

1. style屬性：值為{{top:20}}設定距頂部20px

• Model水平居中實現方式

1. 利用Model組件的wrapClassName設定樣式名稱

• React監聽事件方法時手動綁定this

1. 除了使用xxx.bind(this)外，直接使用箭頭函數定義方法會自動綁定this到當前React實例上

   handleConfirm = (type) => {
           Modal[type]({
               title: '確認？',
               content:'你確認你學會了React了嗎？',
               onOk() {
                   console.log('ok')
               },
               onCancel() {
                   console.log('Cancel')
               }
           })
   }　　

• React事件調用方法並傳參

1. onClick事件內容若為this.handleConfirm('confirm')表示一開始就會自動調用，無法傳參；
2. 當需要傳參時，需要將onClick中的內容變為：箭頭函數返回代參的調用方法，從而實現點擊時執行函數並傳參調用方法

   onClick={() => this.handleConfirm('confirm')}

3. 傳遞的參數如果想作為對象的鍵時，需要用[]進行包裹，如果沒包裹直接放置鍵的位置則視為變量而報錯　　

 

三、加載中Spin　

　　

• pages->ui->loadings：對應路由/admin/ui/loadings

import React from 'react';
import {Card, Spin, Icon, Alert} from 'antd'
import './ui.less'

export default class Loadings extends React.Component{
    render() {
        const icon = <Icon type="loading" style={{fontSize:24}}/>
        return (
            <div>
                <Card title="Spin用法" className="card-wrap">
                    <Spin size="small"/>
                    <Spin style={{margin:'0 10px'}}/>
                    <Spin size="large"/>
                    <Spin indicator={icon} style={{marginLeft:10}}/>
                </Card>
                <Card title="內容遮罩" className="card-wrap">
                    <Alert 
                        message="React"
                        description="歡迎使用柳柳版信息框"
                        type="info"
                    />
                    <Spin>
                        <Alert 
                            message="React"
                            description="歡迎使用柳柳版警告框"
                            type="warning"
                        />
                    </Spin>
                    <Spin tip="加載中">
                        <Alert 
                            message="React"
                            description="歡迎使用柳柳版警告框"
                            type="warning"
                        />
                    </Spin>
                    <Spin indicator={icon}>
                        <Alert 
                            message="React"
                            description="歡迎使用柳柳版警告框"
                            type="warning"
                        />
                    </Spin>
                </Card>
            </div>
        )
    }
}

• Spin組件

1. indicator屬性：加載指定的圖標indicator={icon}

   const icon = <Icon type="loading"/>;
   <Spin indicator={icon}/>

2. size屬性：設置大小
3. tip屬性：當作為包裹元素時，可以自定義描述文案

   tip:"加載中" 
   

4. style={{fontSize:24}}  調整顯示圖標的大小

• 樣式注意

1. style={{marginLeft:10}}，marginLeft:xx ，xx是數字可以省略px
2. 如果是style={{margin:'0 10px'}}，xx 是字符串的情況,則不能省略px

• Alert組件

1. type屬性：表示提示的樣式，有四種選擇 success、info、warning、error
2. message屬性：表示提示內容(設置標題信息)
3. description屬性：表示提示的輔助性文字介紹(設置具體描述的內容)

• 任意組件蒙板加載效果

1. <Spin>組件內嵌套自閉合組件（如<Alert />）

 

四、通知提醒Notification　　

　　

• pages->ui->notice.js：對應路由/admin/ui/notification

import React from 'react';
import {Card, Button, notification} from 'antd'
import './ui.less'

export default class Notice extends React.Component{
    openNotification = (type, direction) => {
        if(direction){
           notification.config({
               placement: direction
           })
        }
        notification[type]({
            message:'發工資了',
            description:'上個月考勤22天，遲到12天，實發工資2500，請笑納'
        })
    }
    render(){
        return (
            <div>
                <Card title="通知提醒" className="card-wrap">

              notification.config({
                  placement: direction
              })
           }

               description:'上個月考勤22天，遲到12天，實發工資2500，請笑納'
           })
    }　　

 

五、全局提示框Message　　

• pages->ui->messages：對應路由/admin/ui/messages

import React from 'react';
import {Card, Button, message} from 'antd'
import './ui.less'

export default class Messages extends React.Component{
       showMessage = (type) => {
           message[type]("恭喜你，React課程晉級成功");

        let lastIndex;
        this.state.panes.forEach((pane, i) => {

        const panes = this.state.panes.filter(pane => pane.key !== targetKey);
        if (lastIndex >= 0 && activeKey === targetKey) {
          activeKey = panes[lastIndex].key;
        }
        this.setState({ panes, activeKey });
    }

    render() {
        return (
            <div>
                <Card title="Tab頁簽" className="card-wrap">

                                return <TabPane 
                                     tab = {panel.title}
                                     key = {panel.key}     
                                >{panel.content}</TabPane>
                            })
                        }
                    </Tabs>
                </Card>
            </div>
        )
    }
}

• Tabs組件

1. type屬性：頁簽的基本樣式
2. activeKey屬性：當前激活頁簽的key
3. defaultActiveKey屬性：初始化選中面板的 key，如果沒有設置 activeKey
4. hideAdd屬性：是否隱藏加號圖標，在 type="editable-card" 時有效
5. onChange方法：切換面板的回調
6. onEdit方法：新增和刪除頁簽的回調，在 type="editable-card" 時有效

• Tabs.TabPane

1. 頁簽面板：使用Tabs組件時必須先初始化TabPane

   const TabPane = Tabs.TabPane; 

2. tab屬性：選項卡頭顯示文字

3. key屬性：對應activeKey

4. forceRender屬性：被隱藏時是否渲染 DOM 結構　　

• Tabs帶圖頁簽

1. 指定圖標：用Icon組件
2. 注意：JSX語法，{}根對象中不能直接同時套用<Icon />和文字，外層必須包裹一個根元素<span></span>

   tab={<span><Icon type="plus" />增加</span>
   

• Tabs動態頁簽

1. JS變量循環顯示：定義生命周期方法componentWillMount執行 


2. type="editable-card"：指定樣式為可編輯的卡片樣式

3. onChange事件：設置頁簽改變時調用方法,設置激活的key

4. onEdit、add、remove方法：直接從官網復制過來即可

 

七、畫廊gallery　　

• pages->ui->gallery：對應路由/admin/ui/gallery

import React from 'react';
import {Card, Row, Col, Modal} from 'antd'
import './ui.less'

export default class Gallery extends React.Component{
    state = {
        visible: false
    }
    openGallery = (imgSrc) => {
        this.setState({
            visible: true,
            currentImg: '/gallery/'+imgSrc
        })
    }
    render(){
        const imgs = [
            ['1.png','2.png','3.png','4.png','5.png'],
            ['6.png','7.png','8.png','9.png','10.png'],
            ['11.png','12.png','13.png','14.png','15.png'],
            ['16.png','17.png','18.png','19.png','20.png'],
            ['21.png','22.png','23.png','24.png','25.png']
        ]
        const imgList = imgs.map((list) => list.map((item) => 
            <Card
               style={{marginBottom:10}}
               cover={<img src={'/gallery/'+item} onClick={() => this.openGallery(item)}/>}
            >
                <Card.Meta 
                    title="React Admin"
                    description="66 Elena gallery"
                />
            </Card>
        ))
        return (
            <div className="card-wrap">
                <Row gutter={10}>
                   <Col md={5}>
                       {imgList[0]}
                   </Col>
                   <Col md={5}>
                       {imgList[1]}
                   </Col> 
                   <Col md={5}>
                       {imgList[2]}
                   </Col> 
                   <Col md={5}>
                       {imgList[3]}
                   </Col> 
                   <Col md={4}>
                       {imgList[4]}
                   </Col>  
                </Row>
                <Modal 
                    width={300}
                    height={500}
                    visible={this.state.visible}
                    title="圖片畫廊"
                    onCancel={() => {
                        this.setState({
                            visible: false
                        })
                    }}
                    footer={null}
                >
                    {<img src={this.state.currentImg} style={{width:'100%'}}/>}
                </Modal>
            </div>
        )
    }
}

• Card組件

1. cover屬性：卡片封面

• Card.Meta

1. 使Card組件支持更靈活的內容：靈活內容
2. title屬性：表示標題內容
3. description屬性：表示描述內容

• 柵格布局區塊間隔

1. 關鍵：Row 的 gutter 屬性，常使用(16+8n)px作為左右間隙（n為自然數）
2. Col 使用樣式設置間隙：style={{ marginBottom: 10}}

   <Card
           style={{marginBottom:10}}
           cover={<img src={'/gallery/'+item} onClick={() => this.openGallery(item)}/>}
   >
           <Card.Meta 
                     title="React Admin"
                     description="66 Elena gallery"
            />
   </Card>
   

• 點擊查看大圖

1. onClick點擊事件：使用箭頭函數,傳遞 item

2. 關閉底部按鈕：footer={null}

3. 設置Modal寬高：width={300} height={500}

4. 控制Modal顯示：設置visible, onCancel　

 

八、輪播Carousel　　

　　

• pages->ui->carousel：對應路由/admin/ui/carousel

import React from 'react';
import {Card, Carousel} from 'antd'
import './ui.less'

export default class Carousels extends React.Component{
    render(){
        return (
            <div>
                <Card title="文字背景輪播" className="card-wrap">
                    <Carousel autoplay effect="fade">
                        <div><h3>Ant Motion Banner - React</h3></div>
                        <div><h3>Ant Motion Banner - Vue</h3></div>
                        <div><h3>Ant Motion Banner - Angular</h3></div>
                    </Carousel>
                </Card>
                <Card title="圖片輪播" className="card-wrap slider-wrap">
                    <Carousel autoplay>
                        <div><img src="/carousel-img/carousel-1.jpg"/></div>
                        <div><img src="/carousel-img/carousel-2.jpg"/></div>
                        <div><img src="/carousel-img/carousel-3.jpg"/></div>
                    </Carousel>
                </Card>
            </div>
        )
    }
}

• Carousel組件

1. vertical屬性：表示是否垂直顯示
2. dots屬性：表示是否顯示面板指示點
3. autoplay屬性：表示是否自動切換
4. easing屬性：表示動態效果
5. effect屬性：表示動畫效果函數
6. beforeChange：切換面板的回調
7. afterChange：切換面板的回調

• 圖片輪播

1. autoplay：設置自動切換
2. effect="fade"：指定淡入淡出動畫，不指定默認為scalex動畫
3. 輪播組件開始並沒有顯示：需要引入官網demo的樣式或自定義樣式

   /* Carousel For demo */
    .ant-carousel .slick-slide {
     text-align: center;
     height: 160px;
     line-height: 160px;
     background: #364d79;
     overflow: hidden;
   }
   
   .ant-carousel .slick-slide h3 {
     color: rgba(246, 250, 33, 0.966);
   }　　

4. 自定義樣式：修改圖片的默認高度，!important設置優先級

   // 圖片輪播
   .slider-wrap .ant-carousel .slick-slide {
     height: 240px!important;
   }　　

 

九、路由及樣式　　

• router.js：配置Admin組件的子路由

import React from 'react'
import {HashRouter, Route, Switch} from 'react-router-dom'
import App from './App'
import Login from './pages/Login'
import NoMatch from './pages/NoMatch'
import Admin from './admin'
import Home from './pages/Home'
import Buttons from './pages/ui/buttons'
import Modals from './pages/ui/modals'
import Loadings from './pages/ui/loadings'
import Notice from './pages/ui/notice'
import Messages from './pages/ui/messages'
import Tabs from './pages/ui/tabs'
import Gallery from './pages/ui/gallery'
import Carousel from './pages/ui/carousel'

export default class IRouter extends React.Component{

    render() {
        return (
           <HashRouter>
               <App>
                  <Route path="/login" component={Login}></Route>
                  <Route path="/admin" render={() => 
                      <Admin>
                          <Switch>
                            <Route path="/admin/home" component={Home}></Route>
                            <Route path="/admin/ui/buttons" component={Buttons}></Route>
                            <Route path="/admin/ui/modals" component={Modals}></Route>
                            <Route path="/admin/ui/loadings" component={Loadings}></Route>
                            <Route path="/admin/ui/notification" component={Notice}></Route>
                            <Route path="/admin/ui/messages" component={Messages}></Route>
                            <Route path="/admin/ui/tabs" component={Tabs}></Route>
                            <Route path="/admin/ui/gallery" component={Gallery}></Route>
                            <Route path="/admin/ui/carousel" component={Carousel}></Route>
                            <Route component={NoMatch}></Route>
                          </Switch>
                      </Admin>
                  }></Route>
                 <Route path="/order/detail" component={Login}></Route>
               </App>
           </HashRouter>
        )
    }
}

• pages->ui->ui.less：設置ui目錄下所有組件的樣式　　

.card-wrap{
    margin-bottom: 10px;
    button{
        margin-right: 10px;
    }
}
/* modals */
/* use css to set position of modal */
.vertical-center-modal {
    text-align: center;
    white-space: nowrap;
  }
  
  .vertical-center-modal:before {
    content: '';
    display: inline-block;
    height: 100%;
    vertical-align: middle;
    width: 0;
  }
  
  .vertical-center-modal .ant-modal {
    display: inline-block;
    vertical-align: middle;
    top: 0;
    text-align: left;
  }

 /* Carousel For demo */
 .ant-carousel .slick-slide {
  text-align: center;
  height: 160px;
  line-height: 160px;
  background: #364d79;
  overflow: hidden;
}

.ant-carousel .slick-slide h3 {
  color: rgba(246, 250, 33, 0.966);
}

// 圖片輪播
.slider-wrap .ant-carousel .slick-slide {
  height: 240px!important;
}
