少了1个e，在代码部分补回，否则会报错
<!DOCTYPE>
<html>
<head>
<meta charset="utf-8">
<title></title>
<script src="./js/react.js"></script>
<script src="./js/react-dom.js"></script>
<script src="./js/browser.min.js"></script>
<style>
*{ margin:0px; padding:0px;} </style>
</head>
<body>
<div id="dome"></div>
<div id="test"></div>
<script type="text/babel">
var Fix = React.createClass({
getInitialState:function(){
return{
val:''
}
},
handleChange:function(e){
this.setState({
val:e.target.value
})
},
render:function(){
return(
<div>
user:<input type="text" name="user" value={this.state.val} onChange={this.handleChange} />
<br /><br />
name:<input type="text" name="username" defaultValue="updateOK" />
</div>
);
}
});
ReactDOM.render(
<Fix />,
document.getElementById('dome')
);
</script>
</body>
</html>
效果如下所示：
