Question

当我尝试在nodejs中运行我的javascript（firebase.js取自https://firebase.google.com/docs/web/setup）时出现错误 ReferenceError：self未定义：

C:\Program Files\nodejs>node.exe c:\Temp\firebase.js
c:\Temp\firebase.js:535
I.prototype.onTokenRefresh=function(){throw this.a.create("only-available-in-window");};I.prototype.onTokenRefresh=I.prototype.onTokenRefresh;I.prototype.setBac
kgroundMessageHandler=function(){throw this.a.create("only-available-in-sw");};I.prototype.setBackgroundMessageHandler=I.prototype.setBackgroundMessageHandler;I
.prototype.delete=function(){D(this.c)};var J=function(a,b){var c={};return c["firebase-messaging-msg-type"]=a,c["firebase-messaging-msg-data"]=b,c};var K=self,
P=function(a){I.call(this,a);var b=this;this.a=new firebase.INTERNAL.ErrorFactory("messaging","Messaging",x);K.addEventListener("push",function(a){return L(b,a)
},!1);K.addEventListener("pushsubscriptionchange",function(a){return N(b,a)},!1);K.addEventListener("notificationclick",function(a){return O(b,a)},!1);this.b=nu
ll};f(P,I);



ReferenceError: self is not defined
    at Object.<anonymous> (c:\Temp\firebase.js:535:476)
    at Object.<anonymous> (c:\Temp\firebase.js:547:800)

    at startup (bootstrap_node.js:151:9)

我能做些什么来避免它？

Answer 1

K被设置为＆＃39; self＆＃39; （var K = self），但是＆＃39; self＆＃39;尚未定义。如果您从其他来源复制此代码，请确保获得所有这些代码。从它的外观来看，我认为你可以改变自我＆＃39;到这个＆＃39;。

ReferenceError：未定义self
