I have search input where user will enter value and matched records will be shown. I am calling getSearchResults in ngOnit.

I need to show result when found else if api status is false then need to show 'No results found.'

But when I get api response true then it first shows 'No results found' and then data found.

How can I avoid showing 'No results found' first if api status is true?

I have tried different *ngIf conditions but nothing working as expected.

Ts

  searchResults:any;
  searchResultsFlag:boolean = false;
  horseResults:any;
  userResults:any;

  getSearchResults(){
    this.SpinnerService.show();  
    this.horseService.SearchProfile(this.searchValue).subscribe((results) => {
    
      if (results['status'] === false) {
        this.SpinnerService.hide();  
        this.searchResultsFlag = false;
      } else {
        this.SpinnerService.hide();  
        this.searchResultsFlag = true;
        this.searchResults = results['data'];
        this.horseResults = this.searchResults.horses;
        this.userResults =this.searchResults.users;

      }

    });
  }

HTML

<div  *ngIf="searchResultsFlag">
    <h5  *ngIf="userResults && userResults.length>0">Matched User Results</h5>
    <div >          
   
      <div  *ngFor="let user of userResults">
        ....
      </div>
      
    </div>
    <h5  *ngIf="horseResults && horseResults.length>0">Matched Horse Results</h5>
    <div >   
      
      <div  *ngFor="let horse of horseResults">
      ....
      </div>
    </div>
   
  </div>
  <p *ngIf="!searchResultsFlag">No results found.</p>

It happens because while the http request to the API occurs, your searchResultsFlag os setted as false.

To fix it, you should create a loading flag:

searchResults:any;
  searchResultsFlag:boolean = false;
  loadingFlag = false;
  horseResults:any;
  userResults:any;

  getSearchResults(){
    this.SpinnerService.show();  
    this.loadingFlag = true;
    this.horseService.SearchProfile(this.searchValue).subscribe((results) => {
    
      if (results['status'] === false) {
        this.SpinnerService.hide();  
        this.searchResultsFlag = false;
      } else {
        this.SpinnerService.hide();  
        this.searchResultsFlag = true;
        this.searchResults = results['data'];
        this.horseResults = this.searchResults.horses;
        this.userResults =this.searchResults.users;

      }

      this.loadingFlag = false:

    });
  }

HTML

<div  *ngIf="searchResultsFlag">
    <h5  *ngIf="userResults && userResults.length>0">Matched User Results</h5>
    <div >          
   
      <div  *ngFor="let user of userResults">
        ....
      </div>
      
    </div>
    <h5  *ngIf="horseResults && horseResults.length>0">Matched Horse Results</h5>
    <div >   
      
      <div  *ngFor="let horse of horseResults">
      ....
      </div>
    </div>
   
  </div>
  <p *ngIf="!searchResultsFlag && !loadingFlag">No results found.</p>

You should initialize loadingFlag=true, by default you are loading data, so you wont show text of No Result Data until you get response and modify loadingFlag=false
