    Methods

    • Type Parameters

      Parameters

      • type: new (...args: any[]) => T
      • strict: boolean | Element = true
      • from: ClosestOrigin = ClosestOrigin.target

      Returns T

      Returns the closest element of the provided type to the target (Searches through the element and all its parents to find one of matching type).
