Check if div is descendant of another

javascript

Solution

// x is the element we are checking
while (x = x.parentNode) { 
    if (x.id == "a") console.log("FOUND");
}

Problem

Best way to find out if element is a descendant of another there is another question, very similiar to this one but its jquery. so, how do I do it in js ? I have divs a, b, c, d nested in this order. also, not sure if matters, there is another a, b, c... and another. its not just a single element. there is many by same id/class. so I want to see if d has a parent(no matter how deep it is nested, as long as there is some parent on top its ok) called a. edit: also, I had this idea that I could check childnodes of "a" and see if "d" is one of them, but couldnt implement it. if someone can get it working, itd be awesome.
