[javascript] Can you target an elements parent element using event.target?

I am trying to change the innerHTML of my page to become the innerHTML of the element I click on, the only problem is that i want it to take the whole element such as:

<section class="homeItem" data-detail="{"ID":"8","Name":"MacBook Air","Description":"2015 MacBook A…"20","Price":"899","Photo":"Images/Products/macbookAir.png"}"></section>

Whereas the code that i have written in javascript:

function selectedProduct(event){
  target = event.target;
  element = document.getElementById("test");
  element.innerHTML = target.innerHTML;
}

will target the specific element that i click on.

What i would like to achieve is when i click on anywhere in the <section> element, that it will take the innerHTML of the whole element rather than the specific one that i have clicked.

I would presume it is something to do with selecting the parent element of the one that is clicked but i am not sure and can't find anything online.

If possible i would like to stay away from JQuery

handleEvent(e) {
  const parent = e.currentTarget.parentNode;
}

$(document).on("click", function(event){
   var a = $(event.target).parents();
   var flaghide = true;
    a.each(function(index, val){
       if(val == $(container)[0]){
           flaghide = false;
        }
    });
    if(flaghide == true){
        //required code
    }
})

To use the parent of an element use parentElement:

function selectedProduct(event){
  var target = event.target;
  var parent = target.parentElement;//parent of "target"
}

function getParent(event)
{
   return event.target.parentNode;
}

Examples: 1. document.body.addEventListener("click", getParent, false); returns the parent element of the current element that you have clicked.

2. If you want to use inside any function then pass your event and call the function like this : function yourFunction(event){ var parentElement = getParent(event); }

var _RemoveBtn = document.getElementsByClassName("remove");
for(var i=0 ;  i<_RemoveBtn.length ; i++){
    _RemoveBtn[i].addEventListener('click',sample,false);
}
function sample(event){
    console.log(event.currentTarget.parentNode);    
}
