hot to get role attribute jquery code example

Example 1: jquery attr

$( some_item ).attr( "id", "some-id" );
// for setting multiple attributes, it's similar to the css() property. However, quotes are not always required for attr()
$( some_item ).attr({
  id: "some-id",
  // or others.
  title: "Opens in a new window",
  // attributes which contain dash(-), should be covered in quotes.
  "data-value": "internal link"
});

Example 2: select element as role in jquery

// remove active class from all elements
document.querySelectorAll('[role="presentation"]').forEach(function (el){
el.classList.remove("active");
});

// add class 'active' to last element
document.querySelectorAll('[role="presentation"]:last-of-type')[0].classList.add("active")
