How come I am unable to retrieve a field within a method of the same class?

Here is a snippet of the code from my component:

export class RootComponent {
  isActive = true;

  setVal(j) {
    if (j == 0) {
      isActive = false;
    }
  }
}

I am new to Angular and I have a question that might seem basic. Why am I unable to access or modify the isActive field within the same class method, such as setVal?

Answer №1

Employ this method for accessing the variable/field that follows

export class mainComponent{
   isDisabled = false;

   updateValue(x){
    if(x==0){
    this.isDisabled = true;
    }
 }

}

Answer №2

If you want to modify the value of a class-level variable within a class method, you must utilize the this keyword. This keyword specifies the scope in which the function should update variable values. Failing to include it will confine the scope to the function itself.

For instance, this.isActive = false;
