无法以角形

Question

我在同一TypeScript（.ts）文件中使用两个类。

有两个类 Class1 和 Class2 。我在 Class2 中调用 Class1 函数以根据 Class2 的响应设置值。我可以在同一功能中（通过控制台）设置值，但无法在 Class1 函数中获取值。

下面是我的 Class1 ：

@Component({
  selector: 'app-new-mission',
  changeDetection: ChangeDetectionStrategy.OnPush,
  templateUrl: './new-mission.component.html',
  styleUrls: ['./new-mission.component.css']
})

export class NewMissionComponent implements OnInit {
   public data_option_id:any ;
   public data_option_label:any;

   dataOptionLabelAdd(dataoptionid, label) {

     this.data_option_id = dataoptionid;
     this.data_option_label = label;
     console.log(this.data_option_id) // I can see values setted here 
     console.log(this.data_option_label) // I can see values setted here 

     addDataField() {
       console.log(this.data_option_id) // I want to get values here
       console.log(this.data_option_label) 
     }
 } }

下面是我的 Class2 ：

@Component({
  selector: 'modal-list.component',
  templateUrl: 'modal-list.component.html',
})

export class FormDialogComponent  {
   // This is to get object from **Class1**
   private missionObj: any;

   constructor(
     private formb: FormBuilder,private 
     newmissionServiceM:NewMissionService,

     public dialogRef: MatDialogRef<FormDialogComponent>,
     //adding parameters for new mission component.
     private http: HttpClient,private route: ActivatedRoute,private 
     router: Router,private fb: FormBuilder,
     private commonService:CommonService,
     private newmissionService:NewMissionService,
     private localeService: BsLocaleService,
     private viewContainerRef: ViewContainerRef,
     private ref: ChangeDetectorRef,
     private atp: AmazingTimePickerService,
     public datepipe: DatePipe,public dialog: MatDialog
     ) { }

     // In this function im calling **Class1** function
     addDataFieldOptions() {
         let dropdownId = 1;
         let data_type_label = "label";
         //creating object for NewMissionComponent
         this.missionObj = new NewMissionComponent(this.http, this.route, this.router, this.fb, this.commonService, this.newmissionService, this.localeService, this.viewContainerRef, this.ref, this.atp, this.datepipe, this.dialog);
      // Calling function
      this.missionObj.dataOptionLabelAdd(dropdownId, data_type_label);

我可以调用 Class2 中的 Class1 的dataOptionLabelAdd函数。在调用函数（dataOptionLabelAdd）时，我可以看到分配的值（在控制台中）。但是我无法在addDataField函数中获取值。我不知道是什么问题。或者，请向我建议其他方法来实现这一目标。预先感谢。
