export class Component implements OnInit {
constructor(
private router: Router,
private userService: PostGetService,
private _Activatedroute: ActivatedRoute
) {}
ngOnInit() {
this.categoryId = this._Activatedroute.snapshot.params['categoryId'];
this.userService.searchListingById(Number(this.categoryId))
.subscribe(res => {
this.rawdata = res.json();
console.log(this.rawdata)
});
}
}
我有一个下拉菜单，我将在其中选择一个类别，并基于该类别我想在另一个页面上显示其相关数据
我有这样的回复，即我需要在下一页显示这些详细信息

这些是我想在其中一个类别 ID 选择中获得的详细信息我不想显示姓名、电子邮件、联系电话等少数详细信息的所有详细信息。
最佳答案
first i created service in service.ts file
searchListingById(categoryId: number): Observable<any> {
if(categoryId == 0 || categoryId == undefined){
return this.getListings().delay(100)
}else{
return this.http.get( this.searchCatUrl+categoryId).delay(100);
}
}
from here i am passing selected dropdown id to search based on that selected id .... then i am calling above service method from my component.ts file
this.userService.searchListingById(this.categoryId)
.subscribe(res => {
this.categoryRawdata = res.json();
});
and values will be stored in categoryRawdata variable and in component.html bind values using this variable
