完成例子： https://github.com/wuyunqiang/RNApp rn端：
//接收来自H5的消息 onMessage = (e)=>{ Log('WebView onMessage 收到H5参数：',e.nativeEvent.data); let params = e.nativeEvent.data; params = JSON.parse(params); Log('WebView onMessage 收到H5参数 json后：',params); }; onLoadEnd =(e)=>{ Log('WebView onLoadEnd e：',e.nativeEvent); let data = { source:'from rn', }; this.web&&this.web.postMessage(JSON.stringify(data));//发送消息到H5 }; <WebView ref={(webview) => { this.web = webview }} style={{width: '100%', height: '100%', justifyContent: 'center', alignItems: 'center'}} source={require('../data/testwebview.html')} onLoadEnd={this.onLoadEnd}//加载成功或者失败都会回调 onMessage={this.onMessage} javaScriptEnabled={true}//指定WebView中是否启用JavaScript startInLoadingState={true} //强制WebView在第一次加载时先显示loading视图 renderError={(e) => { return <View/>; }} />
