我在 Angular 7 中有一個布爾值，我用它在對象構造函數中設置一個值。布爾值作為參數傳遞，我將其存儲在本地。但是，由于某種原因，布爾值總是評估為真。這是有問題的代碼：  ngOnInit() {    this.id = this.route.snapshot.params['id'];    this.showPersonal = this.route.snapshot.params['showPersonal'];    console.log("ngOnInit, this.id: " +  this.id);    console.log("ngOnInit, this.showPersonal: " +  this.showPersonal);    // if showPersonal is true, workRelated i.e. last item in constructor, is false    if (this.showPersonal){      console.log("showPersonal is true, setting work related to false")      this.showWorkRelated = false;    }    else {      console.log("showPersonal is false, setting work related to true")      this.showWorkRelated = true;     }console.log("this.showWorkRelated: " + this.showWorkRelated)這是輸出：todo.component.ts:28 ngOnInit, this.showPersonal: falsetodo.component.ts:32 showPersonal is true, setting work related to falsetodo.component.ts:40 this.showWorkRelated: false我嘗試了很多不同的方法，但它總是評估為真。這段代碼有什么問題？
