how to display object values inside a form in angular?

Question

I want to display individual value of json object into form in angular. How to do that?

output

{
  "Order": {
    "active": true,
    "Orders_Entrydate": "2017-12-31T18:30:00.000Z",
    "LastTouchDateTime": "2018-05-10T05:46:38.702Z",
    "_id": "5af07544eb26f918e0e2ff74",
    "Orders_Name": "Test1",
    "Orders_Number": "1011",
    "Orders_LoanNumber": 1328,
    "Orders_PropertyAddress1": "test address1",
    "Orders_PropertyAddress2": "test address 1",
    "Orders_PropertyCity": "testCity",
    "Orders_Propertyzipecode": 1236,
    "Orders_Countyfee": 500,
    "Orders_Additionalfee": 100,
    "Orders_Customerpricing": 150
  }
}

view-order.ts

export class countyViewOrderComponent implements OnInit {
  orders: any[];

  constructor(private orderService: countyvieworder, private router: Router, private cookie_service: CookieService) {

  }
  getorder() {
    this.orderService.getOrders().subscribe(response => {
      this.orders = response.json();


    })
  }


  onSelect(selectedItem: any) {
    this.cookie_service.put('key', selectedItem._id)
    // this.cookie_service.get('key')
    this.router.navigate(['pages/home/County/orderEntrybyCounty']);


  }



  ngOnInit() {

    this.getorder()


  }


}

getOrderbyOrderNo() service

getOrderbyOrderNo() {
        this.id = this.cookie_service.get('key');
        return this.http.get('http://localhost:8080/View/'+ this.id)

    }

Getting this error:

Argument of type 'Response' is not assignable to parameter of type 'string'.

Please share orderService.getOrderbyOrderNo() code as well. There is a type mismatch. What is the type of the response being returned by getOrderByOrderNo? — Aamir Khan

getOrderbyOrderNo() { this.id = this.cookie_service.get('key'); return this.http.get('localhost:8080/View/'+ this.id) } — rina

Please post the whole function, including the return type, in the original post, not as a comment. — Aamir Khan

Suggest you to make use of HttpClient , that will do conversation for you . HTTPClient is new module in angular which replaced old HTTP one.

import HttpClientmodule in your module

import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    HttpClientModule,
  ],

change in service.ts

   import { HttpClient } from '@angular/common/http';
  constructor(private httpClient: HttpClient) { }

  getOrderbyOrderNo() :Observable<any> {
        this.id = this.cookie_service.get('key');
        return this.httpClient.get('http://localhost:8080/View/'+ this.id)
    }

view-order.ts

 order: any;//no array as you are expecting only one element 
 getorder() {
    this.orderService.getOrders().subscribe(response => {
      this.order = response;
    })
  }

in your code you are using array that is also cause problem

Change the getorder function subscribe to subscribe((response: any))

getorder() {
    this.orderService.getOrderbyOrderNo().subscribe((response: any) => {    
         console.log(response);          
        this.orders=response

    })
}

You are not parsing your response so here this code may be help you

 this.orders=JSON.parse(response);

or you can also do this in your service

return this.http.get('http://localhost:8080/View/'+ this.id).map(data => data.json());

@vikas it will works fine if you use HttpClientModule

Rajan Desai Over a year ago

yes i'm using httpclientModule . import {Http, RequestOptions, Headers} from "@angular/http"; constructor(private _http: Http) { }

Rajan Desai Over a year ago

@Vikas i tried and its working in my machine and if you have any query with your code then share me so i can try it on my machine and help you to find solution

chandrakant Over a year ago

@rajan i am sure that you have first define HttpModule and then after override HttpClientModule, is it right ????

Vikas Over a year ago

I don't have any query all I wanted to convey is HttpModule is deprecated if OP is using Angular version> 4.3 then he should be using HttpClientModue which by default formats the response to JSON so you do not require resposne.json()
