- (void)removeAllUserScripts; //移除所有脚本
- (void)addScriptMessageHandler:(id <WKScriptMessageHandler>)scriptMessageHandler name:(NSString *)name;//添加scriptMessageHandler到所有的frames中,html5中需要添加window.webkit.messageHandlers.<name>.postMessage(<messageBody>)方法，来实现js与oc之间的桥梁
- (void)removeScriptMessageHandlerForName:(NSString *)name;//根据name移除所注入的scriptMessageHandler
