详解react使用react-bootstrap当*造车

上一篇我们谈了谈如何配置react的webpack环境

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*，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：

点击之后会变为loading...，可以自己点击一下

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>
    );
  }
}

 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" id="bg-nested-dropdown">
     <menuitem eventkey="1">dropdown link</menuitem>
     <menuitem eventkey="2">dropdown link</menuitem>
  </dropdownbutton>
</buttongroup>

//上拉
<buttontoolbar>
  <splitbutton title="dropup" dropup id="split-button-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="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" active>link 1</listgroupitem>
          <listgroupitem href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" >link 2</listgroupitem>
          <listgroupitem href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" 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" id="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 id="overload-left">tooltip overload!</tooltip>
        </overlay>
        <overlay {...sharedprops} placement="top">
          <tooltip id="overload-top">tooltip overload!</tooltip>
        </overlay>
        <overlay {...sharedprops} placement="right">
          <tooltip id="overload-right">tooltip overload!</tooltip>
        </overlay>
        <overlay {...sharedprops} placement="bottom">
          <tooltip id="overload-bottom">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）

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
