The JavaScript implementation gets the prev and next method of an element's neighboring sibling nodes _javascript skills

The example in this article describes the Prev and next method of the JavaScript implementation to obtain the neighboring sibling nodes of an element. Share to everyone for your reference, specific as follows:

/**
* Gets the adjacent element
* @param ele reference element
* @param type, the last (1) or next (0)
* @return Returns the found element Dom object, NONE returns null
* *.
function Getnearele (ele, type) {
  type = = Type = 1? "PreviousSibling": "NextSibling";
  var nearele = Ele[type];
  while (Nearele) {
    if (Nearele.nodetype = = 1) {return
      nearele;
    }
    Nearele = Nearele[type];
    if (!nearele) {break
      ;
    }
  }
  return null;
}
/**
* Gets the last element of the current executing object
/function prev () {return
  Getnearele (this, 1);
}
/**
* Gets the next element of the current executing object/
function next () {return
  Getnearele (this, 0);
}
var ele = document.getElementById ("xxx");
var prevelement = Prev.call (ele);
var nextelement = Next.call (ele);
