Answer 1

I am wondering why you need the index of that node ?

You can assign

var trNode = document.getElementsByTagName("td")[291].parentNode;

Answer 2

var parent = document.getElementsByTagName("td")[291].parentNode;
var index = -1;
for (var i = 0; i < parent.childNodes.length; i++) {
  if (parent.childNodes.item(i) == tr) {
    index = i;
    break;
  }
}
