javascript - React 组件之间的通信

Question

在尝试使用 React 时，我遇到了架构问题。我想使用 React JS 以最可重用的方式切换选项卡。

因此，理想情况下，我正在寻找一种方法，在单击 TabHeading 时，我停用 TabHeader 标题中的其他 TabHeading，并激活 TabContent 中相应的 TabPane(来自 this.props.target)。

$(".tab-pane").hide();
$(React.findDOMNode(this.props.target)).show();

我想避免上述解决方案。我不想在任何地方使用 classNames，或者将父组件作为 prop 传递。Angular 有 $parent 或某种变量来调用父组件上的函数吗？是否有类似的方法而不显式传递父级？有没有办法和 sibling 沟通？请帮忙。

<Tabs>
    <TabHeader>
        <TabHeading active="active" target={self.refs.pane1}>
            Heading 1
        </TabHeading>
        <TabHeading target={self.refs.pane2}>
            Heading 2
        </TabHeading>
    </TabHeader>
    <TabContent>
        <TabPane active="active" ref="pane1">
            Pane 1
        </TabPane>
            <TabPane ref="pane2">
               Pane 2
            </TabPane>
    </TabContent>
</Tabs>

我找到了没有 Flux 的答案。请随时提出改进方法。

Tabs.js

var React = require("react");
var $ = require("jquery");


var TabHeading = React.createClass({

render : function(){
        var view  ;

        return (
                <div onClick={this.props.handleClick} className={this.props.active? "active tab-heading" : "tab-heading"}>
                        {this.props.children}
                    </div>      
            );
    }   
 });



var TabPane = React.createClass({
render : function(){

        return (
            <div className={this.props.active? "active tab-pane" : "tab-pane"}>
                    {this.props.children}
                </div>
            );
    }   
});

var Tabs = React.createClass({

handleClick:function(){
    this.props.active = arguments[0];
    this.forceUpdate();
},
render : function(){
    var self = this;
    console.log("rendering");
    var tabHeadings = this.props.tabHeadings.map(function(item,index){
         active = (index==self.props.active);
         return <TabHeading key={index} handleClick={self.handleClick.bind(self,index)} index={index} active={active}>{item}</TabHeading>
    });
    var tabPanes= self.props.tabPanes.map(function(item,index){
         active = (index==self.props.active);
         return <TabPane key={index} active={active}>{item}</TabPane>

    });

    return (
                <div className="tab">
                    <div className="tab-header">
                            {tabHeadings}
                    </div>
                    <div className="tab-content">
                            {tabPanes}
                    </div>
                </div>
        );
}
});

module.exports = Tabs;

render:function(){

    var self = this;

    var tabHeading1 = (
            <p> Heading 1 </p>
