How to get parent object tag of selected text?

Question

JavaScript

Please tell me how to get the tag of the parent object of the selected text. I have codec:

let range = window.getSelection().getRangeAt(0);
parObj = getContainingP(range.commonAncestorContainer);
return alert(parObj ? parObj.id : 'null' );

function getContainingP(node) {
    while (node) {
        if (node.nodeType == 1 && node.tagName.toLowerCase() == "p") {
            return node;
        }
        node = node.parentNode;
    }
}

...well, how do I get the name of the parent tag? Thanks to.
