'Click' function not working within typescript/angular after finding element using 'document.querySelector'


'Click' function not working within typescript/angular after finding element using 'document.querySelector'

it fixes the issue You should avoid using native JavaScript API as much as possible when using Angular.
Try this instead:
code :
//In your component class properties
@ViewChildren('el') elList: QueryList<ElementRef>;

//In the relevant part of your code
this.elList.find(x => x.nativeElement.getAttribute('data-convo-id') == currentID).click();

Why is document.querySelector not working on pseudo element?

This might help you If you want to style pseudo elements from javascript you have to use the CSSOM to inject the rules. It's not trivial, but it's possible.
code :
var sheet = document.styleSheets[0]; //get style sheet somehow
var rules = sheet.rules; 
sheet.insertRule('div:before { display: none; }', rules.length);

wish help you to fix your issue You can use querySelectorAll() to get multiple element references matching a selector
code :
angular.element(document.querySelectorAll('.x'))

hope this fix your issue You can get a reference to the video element by using a local variable and @ViewChild
code :
@Component({
  selector: 'my-app',
  template : `<video #my-video></video>`
})
export class App implements AfterViewInit {

  // myVideo == #my-video
  @ViewChild('myVideo') myVideo: any;

  afterViewInit() {
    let video = this.myVideo.nativeElement;
    video.src = URL.createObjectURL(yourBlob);
    video.play();
  }

it helps some times Your question is missing a lot of details but can you try to explicitly cast it as an HTMLElement:
code :
let yourElem= <HTMLElement>document.querySelector('.class');
yourElem.click();

With these it helps The reason why it's working also in the first way is that you included jQuery before AngularJS, so actually when you call angular.element angular returns to you an instance of $, and you are able to use angular.element with selectors too.
Otherwise AngularJS has a built-in version of jQuery that is jQlite, and you need to pass the HTML element inside angular.element in order to get back a jQlite object, that is a standard jQlite object with some more properties added by AngularJS.
code :
console.log(angular.element('#test'));
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="test">
  ciao
</div>
console.log(angular.element('#test'));

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div id="test">
  hello

console.log(angular.element(document.querySelector('#test')));
