Is there anything equivalent to php’s Domdocument class for javascript or Angularjs?

Question

Situation: Given the url, you would need all the classes used inside the page.

There is a class method DomDocument that I would need to use (->loadHTMLFile($url)).

There is something equivalent to this class for javascript or angularjs?

• I needed to carry a url and then do a search for tags (I would like to get only the classes)

  $dom = new DOMDocument;
  $dom->loadHTMLFile('https://www.youtube.com/'); // a url vai aqui
  $elements = $doc->getElementsByTagName('input');
  
  foreach($elements as $el){
      //retorna todas as classes referente aos inputs
      echo $el->getAttribute('class')."\n";
  }
  

In javascript it is possible to only search for the current page (where the script is inserted), for example:

• I wanted to make a die url and give the search for classes

  var $elements = document.getElementsByTagName('input');
  var show = "";
  for(var i = 0; i < $elements.length; i++){
      var tagClass = $elements[i].getAttribute('class');
      if( tagClass !== null){
          show += tagClass ;
      }
  }
  alert(show);
