Track ALL clicked elements using JavaScript

Question

I want to track ALL elements that are clicked on a HTML-page. I need a good way to reference exactly which element was clicked (so I will be able to replay the clicks on a identical separate HTML-page later on).

Is there a good way to reference which element that was clicked?

I could add unique id's and classnames to every single element on the page. But I figure there must be another way?

The HTML-page which I will be replaying the clicks on will be identical.

Something like this (but more exact information which element it was, maybe that's possible to collect)...

Code to track which element was clicked

var arrayWithElements = new Array();

document.onclick = clickListener;

function clickListener(e) {
    var clickedElement;
    if(e == null) {
        clickedElement = event.srcElement;
    } else {
        clickedElement = e.target;
    }
    arrayWithElements.push(clickedElement)
    alert(arrayWithElements);
}

Code that will be used on a identical HTML-page

document.someHowGetTheElement().onclick();

I guess you are looking for something like this:

---

var arrayWithElements = new Array();

function clickListener(e) 
{   
    var clickedElement=(window.event)
                        ? window.event.srcElement
                        : e.target,
        tags=document.getElementsByTagName(clickedElement.tagName);

    for(var i=0;i<tags.length;++i)
    {
      if(tags[i]==clickedElement)
      {
        arrayWithElements.push({tag:clickedElement.tagName,index:i}); 
        console.log(arrayWithElements);
      }    
    }
}

document.onclick = clickListener;

---

It will store on every click an object that contains the tagName of the element and the index. So you may access this element in another "instance" of this document by using

document.getElementsByTagName(item.tag)[item.index]

(where item is an item of arrayWithElements)
