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。
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);jsFiddle
