Answer 1

Since you are using javascript why don't you just add a property to the div:-

var divs = document.getElementByTagName("div");
for (var i = 0, length = divs.length; i < length; i++)
{
    if (!divs[i].hasBeenRead)
    {       
         fnReadDiv(divs[i]);
         divs[i].hasBeenRead = true;
    }
}
