How to access variables inside a function from outside in another function in typescript?

In my html page onchange, im just calling a method by passing parameters. After retrieving the value, onclick of another button Im calling function2. I need to use the variable from function in function2 in the same class. Im using angular 6 & typescript. My ts file is given below.

export class component extends Lifecycle
cc1: string;
constructor ()
Function (cc1,cc2)

this.cc1 = cc1;
// return cc1;


Function2 ()
console.log(cc1);




Can somebody help me with this?

use this keyword inside any method to access to any property or method related to class.

this

export class component extends Lifecycle
cc1: string;
constructor()
super();

Function(cc1, cc2)
this.cc1 = cc1;
// return cc1;


Function2()
console.log(this.cc1);




You have to call super if you extend the class

super

In Function2, you would use this.cc1 as shown below (note that I renamed the parameters passed to Function1 to clarify their difference from the class-level variable)

Function2

this.cc1

Function1

export class component extends Lifecycle
cc1: string;

constructor ()
super();


Function1 (_cc1, _cc2)
this.cc1 = _cc1;


Function2 ()
console.log(this.cc1);




In Function 2

Function2 ()
console.log(this.cc1);

}
