我按照一些教程如
http://www.html5rocks.com/en/tutorials/frameworks/angular-websockets/在我的node.js服务器和angular.js客户端实现socket.io,一切正常.
TS2496: The 'arguments' object cannot be referenced in an arrow function in ES3 and ES5. Consider using a standard function expression.
关于以下服务代码:
on(eventName:string,callback) { this.socket.on(eventName,() => { var args = arguments; // <-- here the compilation error this.$rootScope.$apply(() => { callback.apply(this.socket,args); }); }); } emit(eventName:string,data,callback?) { this.socket.emit(eventName,() => { var args = arguments; // <-- here the compilation error this.$rootScope.$apply(() => { if (callback) { callback.apply(this.socket,args); } }); }); }
我尝试了不同的解决方案,比如https://github.com/Microsoft/TypeScript/issues/1609的第一篇文章中描述的那个,它修复了编译但是破坏了socket.io“on”功能(json对象不再被解释).
知道如何修复或忽略这个打字稿编译错误吗?
使用函数代替()=>
on(eventName:string,callback) { var self = this; this.socket.on(eventName,function() { var args = arguments; self.$rootScope.$apply(() => { callback.apply(self.socket,args); }); }); }
