HTML代码:
<div id="content"></div>
<script src="build/react.min.js"></script>
<script src="build/react-dom.min.js"></script>
<script src="https://cdn.bootcss.com/babel-core/6.1.19/browser.min.js"></script>
<script src="ex1.jsx" type="text/babel"></script>
JSX代码:
// create class
var HelloWord = React.createClass({
render: function () {
return (
<div>
<p>Hello Word!</p>
</div>
);
}
});
// show content
ReactDOM.render(
<HelloWord></HelloWord>, document.getElementById('content')
);
运行后控制台消息:
未捕获的类型错误:无法读取未定义的属性“键”
为什么?
