Function elementExists

  • elementExists(target: undefined | null | Target): boolean

  • Checks if the specified target exists in the DOM.

    Parameters

    • target: undefined | null | Target

      Element, EventTarget, or CSS selector.

    Returns boolean

    true if the specified target exists.

    Remarks

    We allow null or undefined as well because a null or undefined element technically doesn't exist.

      <li id="item-2">Item 2</li>
