function commonParentNode(oNode1, oNode2) {
if (oNode1 === oNode2) {
return oNode1;
}
const parent1 = oNode1.parentNode;
const parent2 = oNode2.parentNode;
if (parent1 === oNode2 || parent1 === parent2) {
return parent1;
}
else if (parent2 === oNode1) {
return parent2;
}
return commonParentNode(parent1, parent2);
}
