Inside my Component ts file , I' ve a "connexion" method:
export class MyClass {
isOpen = false
openConnection(url) {
this.socketClient.connect(this.tokenheader, (response) => {
this.isOpen = true;
this.getResponse()
},
this.errorCallBack
);
}
errorCallBack(error) {
this.isOpen = false; // CANNOT READ 'isopen' of undefined
console.log("Connexion failure" + error);
}
}
This method returns several callbacks for "response" and "error".
As you can see i ve the call of "this.errorCallBack" when error
it's used to print the error message ;
but i ve to set my class variable to false (this.isOpen = false;)
but i get :
CANNOT READ 'isopen' of undefined
Sugesstions ??
