1、问题背景

     点击按钮,记录点击次数


2、实现源码

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title>React记录按钮点击次数</title>
		<link rel="stylesheet" href="../css/base.css" />
		<script type="text/javascript" src="../js/react.js" ></script>
		<script type="text/javascript" src="../js/react-dom.js" ></script>
		<script type="text/javascript" src="../js/browser.min.js" ></script>
		<script type="text/babel">
		    var BtnCounter = React.createClass({
		        getInitialState: function () {
		          return { count: 0 };
		    },
		    handlerClick: function () {
		          this.setState({
		            count: this.state.count + 1,
		          });
		    },
		    render: function () {
		          return (
		            <button onClick={this.handlerClick}>
		              	点击: {this.state.count}
		            </button>
		          );
		        }
		    });
		    ReactDOM.render(
		        <BtnCounter />,
		        document.getElementById("divContainer")
		    );
	    </script>
	</head>
	<body>
		<div id="divContainer" style="cursor: pointer;">
			点击我!
		</div>
	</body>
</html>

3、实现结果

 

4、注意事项

(1)编写js中的type是"text/babel"

(2)函数BtnCounter首字母大写
