var Count = React.createClass({ getInitialState:function(){ return{ count:0 } }, componentDidMount:function(){ this.timer =setInterval(function(){ $.get('http://ip/apishow/pv.php',function(data){ var obj = eval('(' + data + ')'); this.setState({count:obj[0]['value']});
}.bind(this)) }.bind(this),1000) }, render:function(){ return (
<div>
<a>PV: {this.state.count} </a>
</div>
); } }); ReactDOM.render(
