如何在angular9中重新分配变量？

Question

I have a func which calling in ngDoCheck() . That func calls several another func who reassign my variable. But variable change does only in funcs, not a global variable. myVariable allways 0.

myVariable = 0;

ngDoCheck(): any {
    const word: string = this.form.get('word').value;
    this.PasswordStrengthMeter(word, this.myVariable);
    console.log('Value: ' + this.myVariable);
  }


Mainfunc(word: string, myVariable: number): any {
    this.SecondaryFunc(word, myVariable);
    this.AnotherSecondaryFunc(word, myVariable);
    
  }

Answer 1

If it is in the same component, why do you passing that variable to each function? just use it in that function as it's a global variable.

Answer 2

The value of myVariable is being passed to Mainfunc , not a reference .

If you'd like to change the global variable, use this.myVariable directly from your other SecondaryFunc and AnotherSecondaryFunc .

myVariable = 0;

...

Mainfunc(word: string): any {
    this.SecondaryFunc(word);
    this.AnotherSecondaryFunc(word);
}

SecondaryFunc(word: string): any {
    this.myVariable = 5;
}

AnotherSecondaryFunc(word: string): any {
    this.myVariable = 6;
}
