1、问题背景
利用React生成组件类，并显示类中属性以及属性值
2、实现源码
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>React生成组件类</title>
<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 Person = React.createClass({
render:function(){
return <h3>姓名：{this.props.username},年龄：{this.props.age}</h3>
}
});
ReactDOM.render(
<Person username="胡立新" age="23"/>,
document.getElementById("per")
);
</script>
</head>
<body>
<div id="per"></div>
</body>
</html>
