Angular 5 select option value forced to string












0















I've defined a simple select bound to a variable like so:



<select id="client" name="client" [(ngModel)]="order.clientId">

    <option *ngFor="let client of clients" [value]="client.id">

        {{ client.name }}

    </option>

</select>


and the clients is a simple class with a numeric id value:



export class NameAndId {

    id: number;

    name: string;



    constructor(id: number, name: string) {

        this.id = id;

        this.name = name;

    }

}


So I would expect that the value is a number, not a string. And the order.clientId is also defined as a number. However, when I pass the order object through an HttpClient post call like so, it's encoding the value as a string:



return this.http.post<HttpResponse<any>>(this.baseUrl, order, {observe: 'response'});


Why isn't it appearing as a numeric value?
