Angular 4应用程序中,我有一个输入文本框,其中的值必须从模板存储到json数据,im将其用作模拟数据库。我已经在下面编写了服务和保存功能,但无法将其保存在中。json文件。想法或帮助它工作。

<ng-container *ngFor="let data of displayReasonCodes$ | async;let i = index">
<tr class= "row-break">
 <td>  
    <form>
    <form-group>
  <textbox [readOnly]="isEditable" ngModel="{{data .ReasonCode}}"  name="textbox" ></textbox>
        </form-group>
</form>
</td>
<td>
<form>
<form-group>
 <textbox  [readOnly]="isEditable" ngModel="{{data .Description}}" name="textbox1" ></textbox>
</form-group>
 </form>
  </td>

services.ts
@Injectable()


export class CodesService{ 
    constructor(private httpClient:HttpClient, private apiUrlService : ApiUrlService){}

createReasonCodes(data:IReasonCodes){
        var url = this.apiUrlService.getPostfix("/Codes");
        return this.httpClient.post<IPostHttpResponse>(url,codes);
    }

   COMPONENT.TS
save(){

  let newreasoncodeDefinition: IReasonCodes = this.poolModel.get();

  this.rCodesActions.createCodes(newreasoncodeDefinition).
  subscribe(definitionResponse => {
    if(definitionResponse.responseCode ===1 ){
      console.log("The ReasonCode " + newreasoncodeDefinition.ReasonCode + "Created Successfully");

    }
  })


} 

ReasonCode fromUIModel.ts

poolModel: ReasonCodeFormUIModel;
ngOnInit (){
      this.poolModel = new ReasonCodeFormUIModel();

public get() :IReasonCodes {
    let reasonCodes = new ReasonCodes();
    reasonCodes.Code= this.reasoncode;
    reasonCodes.Description = this.description;
return reasonCodes;
}
}
