1.因为jsx将两个花括号之间的内容渲染为动态值，只需要引用对应的变量即可
<!DOCTYPE html>
<html>
<head>
<title>React JS</title>
<script src="../build_0.13/react.js"></script>
<script src="../build_0.13/JSXTransformer.js"></script>
</head>
<body>
<div > </div>
<script type="text/jsx">
var h1 = "question";
var Divider = React.createClass({
render:function(){
return (<div className="divider">
<h1>{h1}</h1>
</div>
);
}
});
//将组件加到对应的元素上
React.render( <Divider />, document.getElementById('example') );
</script>
</body>
</html>
