How to create object like angularjs in angular4

Question

I am using new angular 4 for learning and created project but I need help how to create object like anglarjs $scope.Param = {}; $scope.Param.MyId = "2231dddd";

How to do this in angular4 and post data into service please check below code

export class HomeComponent {
  public forecasts: WeatherForecast[];
  public EntityTypeList: EntityTypeList[];
  public Param: { id: string; };

  CreateDb() {
        this.Param.id = this.selectedValue;
        this.http.post('http://localhost:1101/api/db/CreateDb', this.Param).subscribe(result => {

        }, error => console.error(error));
    }
}

you can directly use public Param = {} and then add property dynamically in it or can create model/interface to define type of object and then use it — jack

You can then declare property like this

public Param : any = {};

Or if your param object is a key value pair of string, you can use:

public param: {[key: string]: string};
