How to use an hidden character in text string using JavaScript.There is one text string which i read and writes back with the hidden character in it (so rewritten text looks sam

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;
    }
}

Answer 2

To answer the question, keep an array of the divs that have been traversed:

var divsChecked = [];
//code that looks at the div
divsChecked.push(div.getAttribute('id'));

However I think that the method that you are using to traverse the items may not be correct with libraries like jQuery you could loop over each div in turn thereby you shouldn't ever see the same div twice unless you run the loop twice.
