Which of the following would not set a class on a DOM element?

Answer: To answer this question, let’s consider several common JavaScript methods and properties related to setting classes on a DOM element:

  1. element.className: This directly sets the class of an element. For example:

    element.className = "new-class";

    This will set the class new-class on the element, replacing any existing classes.

  2. element.classList.add(): This method adds one or more classes to an element without removing existing classes. For example:

    element.classList.add("new-class");

    This will add new-class to the existing class list.

  3. element.setAttribute(): This method can be used to set any attribute of an element, including the class attribute:

    element.setAttribute("class", "new-class");

    This will set the class to new-class just like className.

  4. element.style: This property is used to apply inline styles to an element, not to set classes. For example:

    element.style.backgroundColor = "blue";

    This changes the inline style, not the class.

Based on the explanations above, using element.style would not set a class on a DOM element.

Summary: Among the discussed methods, element.style is used to set styles and does not set a class on a DOM element. Other methods like className, classList.add(), and setAttribute() do set or change classes on elements.
