There are 5 li element and one of them say third li is hidden.Is there a way to apply filter before getting index so that fourth element\'s index should show 2 instead of 3.

        <script>
            $(window).load(function() {
                    jQuery('.addchar').live('hover', function(event) {
                        $("#result").html("Index is:" +$(this).index() );

                    <li class="addchar">two </li>

                    <li class="addchar">four </li>
                    <li class="addchar">five </li>
                </ul>
            </div>
            <div id="result"></div>
        </div>
    </body>
</html>

How about using the visible selector:

$('.addchar:visible').live( ...

EDIT:

Too bad, you could try an alternative approach if that is an option for you:

$(function() {
    $('.addchar:visible').each(function(index) {
        $(this).hover(function() {
            $("#result").html("Index is: " + index);
        });
    });
});

As foreach method iterates every element it became slow when element size rises.I searched and got it working.Thanks to this link.

jQuery('.addchar').live('hover', function (event) {
var cInd = $(this).index();//current index including hidden element
var hidLen = $(this).parent().children("li:lt(" + cInd + "):not(:visible)").length;//total hidden before hovered element
var index = cInd - hidLen;
$("#result").html("Current index :" + cInd +"<br>Tot Hidden Before Current:" + hidLen+"<br> Actual Index:"+index);
});
