您可以通过创建一个负责管理状态的父组件来完成此任务，然后将状态作为道具向下推到子组件。
/** @jsx React.DOM */
var Inputs = React.createClass({
render: function () {
var items = [];
var inputs;
for (var i = 0; i < this.props.count; i++) {
items.push( <input type="text" name={[i]} />);
items.push(<br />);
}
return (
<div className = "col-md-9">
<form action = "/" method = "post" name = "form1">
{items}
<input type="submit" className="btn btn-success" value = "Submit Form" />
</form>
</div>
);
}
});
var Add = React.createClass({
render: function () {
return (<input type = "button" className="btn" value="Add an Input" onClick={this.props.fnClick}/> );
}
});
var Parent = React.createClass({
getInitialState: function(){
return {count:1}
},
addInput: function(){
var newCount = this.state.count + 1;
this.setState({count: newCount});
},
render: function(){
return (
<div>
<Inputs count={this.state.count}></Inputs>
<Add fnClick={this.addInput}/>
</div>
);
}
});
React.renderComponent(<Parent></Parent> , document.body);
