Question

做一个基本示例，但引导程序样式不适用于来自React组件的按钮。它适用于HTML文件中的按钮。我在HTML文件中提供了CDN的bootstrap css。在一个简单的python Web服务器上运行（python -m http.server 8001）。是什么给了什么？

example1.jsx：

// example1.jsx:
var MyPulldown = React.createClass({
    render: function () {
        return <div class="dropdown">
             <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
               Second Dropdown
             </button>
             <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
               <a class="dropdown-item" href="#">Action</a>
               <a class="dropdown-item" href="#">Another action</a>
               <a class="dropdown-item" href="#">Something else here</a>
             </div>
           </div>
    }
});


React.render(
  <div>
     <MyPulldown/>
  </div>,
  document.getElementById('container')
);

Answer 1

在反应中class道具是保留的。您需要使用className

的className

要指定CSS类，请使用className属性。这适用于   所有常规DOM和SVG元素，如<div>，<a>和其他。

var MyPulldown = React.createClass({
    render: function () {
        return <div className="dropdown">
             <button className="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
               Second Dropdown
             </button>
             <div className="dropdown-menu" aria-labelledby="dropdownMenuButton">
               <a className="dropdown-item" href="#">Action</a>
               <a className="dropdown-item" href="#">Another action</a>
               <a className="dropdown-item" href="#">Something else here</a>
             </div>
           </div>
    }
});

无法使用Bootstrap样式将React组件格式化
