Pass data from one component to another in angular

Avatarjulie asked 3 months ago

I am working on a application which contains a search functionality.

Right now I have 2 components in application
1. Navbar
2. SearchGridList

Navbar component contains a text box, in which you type in a search query and hit enter and this component will make a api call and get the data.
When the data comes back, I want to populate this data in an array in SearchGridList component.

I am having a tough time understanding passing data within components in Angular, can someone please take a look at my code and guide me.

navbar.component.ts

import { Component, OnInit, Input, Output } from '@angular/core';
import {DataService} from '../../services/data.service';
import {SearchResults} from '../class/search.class';
import {SearchGridListComponent} from '../search-grid-list/search-grid-list.component';
import { EventEmitter } from '@angular/core';

@Component({
  selector: 'app-navbar',
  templateUrl: './navbar.component.html',
  styleUrls: ['./navbar.component.css']
})
export class NavbarComponent implements OnInit {

  searchQuery : String;
  //searchResultList : Array<any> = [];

  constructor(private dataService :  DataService) { }

  doSearch () : any
  {
    this.dataService.doSQLSearch(this.searchQuery)
    .then ((data:any)=>{
      for (var i =0; i<data.Results.length;i++){
        let searchObj = new SearchResults(data.Results[i]);
        //I want to push data into array from SearchGrid like this 
        resultGridList.push(searchObj);

      }
    });
   }

  ngOnInit() {
  }
}

navbar.component.html

<mat-toolbar class="main-header">
  <a href="/">
  <img src="../../../assets/vms-header-logo.png" id= "header-logo">
  </a>
    <form class="search-box">
      <mat-form-field  class="search-box-full-width">
        <input id ="search-textbox" matInput placeholder="Enter a Barcode, DSID or any search term" name="Search" [(ngModel)]="searchQuery" (keyup.enter)="doSearch()" autocomplete="off">
      </mat-form-field>
    </form>
</mat-toolbar>

search-grid.component.ts

import { Component, OnInit, Input } from '@angular/core';
import {NavbarComponent} from '../navbar/navbar.component';

@Component({
  selector: 'app-search-grid-list',
  templateUrl: './search-grid-list.component.html',
  styleUrls: ['./search-grid-list.component.css'],
})
export class SearchGridListComponent implements OnInit {
  resultGridList : Array <any> = [];
  constructor() { }

  ngOnInit() {
  }

}
