我们可以通过打印的方式将他打印出来看看,如下所示:
<!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 {
islink: true
};
},
handleClick:function(e){
console.log(e);
//alert('这么听话啊');
this.setState({
islink:!this.state.islink
});
},
handleMouseOver:function(){
alert('喂你想干嘛?');
},
handleMouseOut:function(){
alert('吓得我一身冷汗');
},
render:function(){
return(
<div>
<h1>test</h1>
<img src="./images/jj.png" onMouseOver={this.handleMouseOver} onMouseOut={this.handleMouseOut} /> <br /><br />
<p>大家喜欢和他叫朋友吗?<b>{this.state.islink?'喜欢':'不喜欢'}</b></p>
<button onClick={this.handleClick}>有种你就点我</button>
</div>
);
}
});
ReactDOM.render(
<Fix />,
document.getElementById('dome')
);
</script>
</body>
</html>
效果如下所示:
比如我想知道button里面的内容:
