fix:
<WebView style={{backgroundColor:'blue',flex:1}} nativeConfig={//关键部分:这个修改错误 { props: { backgroundColor: '#ffffff', flex: 1, } } } ref = {(webview)=>{this.web = webview}} style={{width:'100%',height:'100%',marginTop:this.isIphoneX()?40:Platform.OS==='ios'?20:0}} source={{uri: this.state.url}} domStorageEnabled={true} mixedContentMode={'always'}//指定混合内容模式。即WebView是否应该允许安全链接(https)页面中加载非安全链接(http)的内容,never,always,compatibility onLoadEnd = {this.LoadEnd}//加载成功或者失败都会回调 onError = {this.isConnNet} javaScriptEnabled = {true}//指定WebView中是否启用JavaScript scalesPageToFit={true} onNavigationStateChange={(e) => { console.log("onNavigationStateChange",e) this.onNavigationStateChange(e) }} startInLoadingState={true} //强制WebView在第一次加载时先显示loading视图 bounces={true}//指定滑动到边缘后是否有回弹效果。 scrollEnabled={true}//是否启用滚动 renderLoading={this.renderLoad}//返回一个加载指示器 renderError={ (e) => {//关键部分:这个出错渲染页面 return null; }} />

renderError={(e) => {//这里判断如果加载报错 返回一个视图 if(e=="NSURLErrorDomain"){ console.log("e NSURLErrorDomain",e); return <View style={{width:"100%",height:"100%",justifyContent:'center',alignItems:"center"}}> <TouchableOpacity activeOpacity={0.8} onPress={this.refresh}> <Text style={{fontSize:16,color:"#333333",}}>无法连接</Text> </TouchableOpacity> </View> }else if(e=="WebKitErrorDomain"){ console.log("e WebKitErrorDomain",e); return null; } console.log("e",e); return <View/>; }}
