react入门之使用react-bootstrap当轮子造车(二)

上一篇我们谈了谈如何配置react的webpack环境

react入门之搭配环境(一)

可能很多人已经打开过官方文档学习了react的基础知识

不管有没有,在介绍react之前,我想先介绍一下react-bootstrap

先懂得使用别人造的轮子,就能更快成为老司机。


好的,源代码奉上:

git clone https://github.com/lingjiawen/react_bootstrap_demo.git

cd react_bootstrap_demo

npm install

npm run dev
打开浏览器输入:localhost:8080

               现在就让我们来看看它能干什么吧!


一、Button

使用Button声明一个按钮,bsSize有如下四个属性,可以分别有大、中、小、超小四种大小的按钮,再用ButtonToolbar包裹起来

                <ButtonToolbar>

<Button bsStyle="primary" bsSize="large">Large button</Button>

<Button bsSize="large">Large button</Button>

</ButtonToolbar>

<ButtonToolbar>

<Button bsStyle="primary">Default button</Button>

<Button>Default button</Button>

</ButtonToolbar>

<ButtonToolbar>

<Button bsStyle="primary" bsSize="small">Small button</Button>

<Button bsSize="small">Small button</Button>

</ButtonToolbar>

<ButtonToolbar>

<Button bsStyle="primary" bsSize="xsmall">Extra small button</Button>

<Button bsSize="xsmall">Extra small button</Button>

</ButtonToolbar>

使用效果如下:


使用well将按钮包裹起来,可以实现如下效果:(well在后面介绍)

<div className="well" style={wellStyles}>

<Button bsStyle="primary" bsSize="large" block>Block level button</Button>

<Button bsSize="large" block>Block level button</Button>

</div>


使用 bsStyle属性可以调整按钮的状态颜色:

<Button>Default</Button>

<Button s>Primary</Button>

<Button bsStyle="success">Success</Button>

下图bsStyle属性分别为:info、warning、danger、link


使用按钮实现点击loading,等待结果的功能:

class LoadingButton extends React.Component{

constructor(props) {

super(props);

this.handleClick = this.handleClick.bind(this);

this.state = { isLoading: false }

}

handleClick() {

this.setState({isLoading: true});

// This probably where you would have an `ajax` call

setTimeout(() => {

// Completed of async action, set loading state back

this.setState({isLoading: false});

}, 2000);

}

render() {

let isLoading = this.state.isLoading;

return (

<Button

bsStyle="primary"

disabled={isLoading}

onClick={!isLoading ? this.handleClick : null}>

{isLoading ? 'Loading...' : 'Loading state'}

</Button>

);

}

}

点击之后会变为loading...,可以自己点击一下


实现按钮的下拉和上拉:

在title中使用Dropdown属性,用DropdownButton包裹下拉,使用Dropup为上拉

//下拉

<ButtonGroup>

<Button>1</Button>

<Button>2</Button>

<DropdownButton title="Dropdown" >

<MenuItem eventKey="1">Dropdown link</MenuItem>

<MenuItem eventKey="2">Dropdown link</MenuItem>

</DropdownButton>

</ButtonGroup>

//上拉

<ButtonToolbar>
<SplitButton title="Dropup" dropup >
<MenuItem eventKey="1">Action</MenuItem>
<MenuItem eventKey="2">Another action</MenuItem>
<MenuItem eventKey="3">Something else here</MenuItem>
<MenuItem divider />
<MenuItem eventKey="4">Separated link</MenuItem>
</SplitButton>
</ButtonToolbar>


二、List

简单列表:

                <ListGroup>

<ListGroupItem href="#" active>Link 1</ListGroupItem>

<ListGroupItem href="#">Link 2</ListGroupItem>

<ListGroupItem href="#" disabled>Link 3</ListGroupItem>

</ListGroup>

使用ListGroup包裹, ListGroupItem就是它的子元素

active:已选中

disable:可以取消它的点击事件


表格:

              <Table striped bordered condensed hover>

<thead>

<tr>

<th>#</th>

<th>First Name</th>

<th>Last Name</th>

<th>Username</th>

</tr>

</thead>

<tbody>

<tr>

<td>1</td>

<td>Mark</td>

<td>Otto</td>

<td>@mdo</td>

</tr>

<tr>

<td>2</td>

<td>Jacob</td>

<td>Thornton</td>

<td>@fat</td>

</tr>

<tr>

<td>3</td>

<td colSpan="2">Larry the Bird</td>

<td>@twitter</td>

</tr>

</tbody>

</Table>


可以点击隐藏的面板:

class CollapsiblePanel extends React.Component {

constructor(props) {

super(props);

this.state = {

open: true

};

}

render() {

return (

<div>

<Button onClick={ ()=> this.setState({ open: !this.state.open })}>

点我隐藏/显示

</Button>

<Panel collapsible expanded={this.state.open}>

Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid.

Nihil anim keffiyeh helvetica, craft beer labore wes anderson cred nesciunt sapiente ea proident.

</Panel>

</div>

);

}

}


三、Overlays

点击弹出的窗口:

class StaticMarkup extends React.Component {

constructor(props) {

super(props);

this.state = {dpName:false};

this.onDisplayOverlays = this.onDisplayOverlays.bind(this);

this.onCloseOverlays = this.onCloseOverlays.bind(this);

}

onDisplayOverlays() {

this.setState({

dpName:true

});

}

onCloseOverlays() {

this.setState({

dpName:false

});

}

render() {

if(this.state.dpName)

return (

<div>

<Button

bsStyle="primary"

onClick={this.onDisplayOverlays}>

弹出框

</Button>

<div className="static-modal" >

<Modal.Dialog>

<Modal.Header>

<Modal.Title>Modal title</Modal.Title>

</Modal.Header>

<Modal.Body>

One fine body...

</Modal.Body>

<Modal.Footer>

<Button onClick={this.onCloseOverlays}>Close</Button>

<Button bsStyle="primary">Save changes</Button>

</Modal.Footer>

</Modal.Dialog>

</div>

</div>

);

else

return (

<div>

<Button

bsStyle="primary"

onClick={this.onDisplayOverlays}>

弹出框

</Button>

</div>

);

}

}

以及点击显示、隐藏的overload

class CustomOverlays extends React.Component{

constructor(props) {

super(props);

this.state = {show: true};

this.toggle = this.toggle.bind(this);

}

toggle() {

this.setState({ show: !this.state.show });

}

render() {

const sharedProps = {

show: this.state.show,

container: this,

target: () => ReactDOM.findDOMNode(this.refs.target)

};

return (

<div style={{ height: 100, paddingLeft: 150, position: 'relative' }}>

<Button ref="target" onClick={this.toggle}>

Click me!

</Button>

<Overlay {...sharedProps} placement="left">

<Tooltip >Tooltip overload!</Tooltip>

</Overlay>

<Overlay {...sharedProps} placement="top">

<Tooltip >Tooltip overload!</Tooltip>

</Overlay>

<Overlay {...sharedProps} placement="right">

<Tooltip >Tooltip overload!</Tooltip>

</Overlay>

<Overlay {...sharedProps} placement="bottom">

<Tooltip >Tooltip overload!</Tooltip>

</Overlay>

</div>

);

}

}


四、轮播

class CarouselInstance extends React.Component {

constructor(props) {

super(props);

}

render() {

return (

<Carousel>

<Carousel.Item>

<img width={900} height={500} alt="900x500" src="http://123.207.238.196/bridge.jpg"/>

<Carousel.Caption>

<h3>First slide label</h3>

<p>Nulla vitae elit libero, a pharetra augue mollis interdum.</p>

</Carousel.Caption>

</Carousel.Item>

<Carousel.Item>

<img width={900} height={500} alt="900x500" src="http://123.207.238.196/bridge.jpg"/>

<Carousel.Caption>

<h3>Second slide label</h3>

<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>

</Carousel.Caption>

</Carousel.Item>

<Carousel.Item>

<img width={900} height={500} alt="900x500" src="http://123.207.238.196/bridge.jpg"/>

<Carousel.Caption>

<h3>Third slide label</h3>

<p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>

</Carousel.Caption>

</Carousel.Item>

</Carousel>

);

}

}


五、一些有用的图标

class MiscellaneousInstance extends React.Component {

constructor(props) {

super(props);

}

render() {

return (

<div>

<div>

<ButtonToolbar>

<ButtonGroup>

<Button><Glyphicon glyph="align-left" /></Button>

<Button><Glyphicon glyph="align-center" /></Button>

<Button><Glyphicon glyph="align-right" /></Button>

<Button><Glyphicon glyph="align-justify" /></Button>

</ButtonGroup>

</ButtonToolbar>

<ButtonToolbar>

<ButtonGroup>

<Button bsSize="large"><Glyphicon glyph="star" /> Star</Button>

<Button><Glyphicon glyph="star" /> Star</Button>

<Button bsSize="small"><Glyphicon glyph="star" /> Star</Button>

<Button bsSize="xsmall"><Glyphicon glyph="star" /> Star</Button>

</ButtonGroup>

</ButtonToolbar>

</div>

<div>

<h1>Label <Label>New</Label></h1>

<h2>Label <Label>New</Label></h2>

<h3>Label <Label>New</Label></h3>

<h4>Label <Label>New</Label></h4>

<h5>Label <Label>New</Label></h5>

<p>Label <Label>New</Label></p>

</div>

</div>

);

}

}


六、表单

表单基础的类函数为:

function FieldGroup({ id, label, help, props }) {

return (

<FormGroup controlId={id}>

<ControlLabel>{label}</ControlLabel>

<FormControl {...props} />

{help && <HelpBlock>{help}</HelpBlock>}

</FormGroup>

);

}

然后使用FieldGroup包裹:

          <FieldGroup

id="formControlsText"

type="text"

label="Text"

placeholder="Enter text"

/>

便可以轻松实现表单!如果你对react有了解,便知道原生的表单是不能直接用的。这个组件简化了许多,但我没用实际用过,所以不知道效果如何。


我写的这些只是抛砖引玉,只是希望大家稍微了解到react-bootstrap大概能做的事

更详细的方法和属性请进入官方网址浏览文档,打开源代码自行研究

有些官方demo没有给完全,可以运行前面的我给的demo,再查看源代码理解(不过我也没有写全,而且结构比较乱)

如果有错误,谢谢各位指出!

如果有更好的资料,也请各位大神不吝赐教!
