Value inserted in global var not able to use outside the function
0
I'm trying to access the value of var Login inside submit(), but not able to do so.Maybe because of race-condition.Why am I not able to access the value of var Login?
Code :
class ABC {
Login : any;
send(){
this.preview.send().subscribe(
(data =>{
this.Login = data;
console.log("This is the new list in send function",this.Login); //Printing value of this.Login
})
);
submit(value) {
// let Log : any = this.Login_Object['login'];
console.log('Inside submit function',this.Login);// Not printing value of this.Login
}
}

You need to bind the this parameter to the function. In the send function you are using an arrow function which binds this automatically. Otherwise you need to call function.bind in the constructor.

Bind the this to the callback function:
send(){
this.preview.send().subscribe(
(data =>{
this.Login = data;
console.log("This is the new list in send function",this.Login); //Printing value of this.Login
}).bind(this)
);
