Question

在我的IDE＆amp;上点击save后在我的浏览器上点击refresh来测试prompt()文件中的index.js功能，我的整个页面都空白，导致我看不到任何内容，只是一个白色的屏幕。我可以发誓我的功能在语法上是正确的。除了包含prompt()函数外，其他所有工作都很完美。

这是我的index.html文件：

<!DOCTYPE html>
<html>

  <head>
     <title>name name</title>
     <meta charset="utf-8">
     <meta name="viewport" content="width=device-width, initial-scale=1">
     <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
     <link rel="stylesheet" href="index.css">
     <link rel="stylesheet" href="body.css">
     <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
     <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
     <script src="https://unpkg.com/react@15/dist/react.js"></script>
     <script src="https://unpkg.com/react-dom@15/dist/react-dom.js"></script>
     <script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.6.16/browser.js"></script>
  </head>

  <body>
    <div id="firstBar"></div>
    <div id="body"></div>

    <script type="text/babel" src="index.js"></script>
    <script type="text/babel" src="body.js"></script>
  </body>

</html>

这是我的index.js文件：

 var TitleBar = React.createClass({
  prompt: function() {
    alert("This works!");
  }

  render: function() {
    return(
     <div className="jumbotron">
      <div className="container">
      <kbd className="fullName"name name/kbd>
        <button onClick={this.prompt} type="button" className="btn btn-primary portfolio">Portfolio</button>
        <button type="button" className="btn btn-primary about">About</button>
        <button type="button" className="btn btn-primary contact">Contact</button>
      </div>
      </div>
    );
  }
});

ReactDOM.render(<TitleBar/>, document.getElementById('firstBar'));

这是我得到的error：

在,属性

之后添加prompt

var TitleBar = React.createClass({
  prompt: function() {
    alert("This works!");
  },

  render: function() {
    ...
  }
})

为什么我的页面空白？
