hide all td in a table excluding the clicked one

Question

I have a fieldset in which I have a table with multiple tr and td . I have to hide all the td upon click event except the td that is clicked inside the fieldset. I tried traversing to the parent tr of the tds that have to be clicked and then set the css to "display:none" . But it seems to hide all the td instead.

Here is my fiddle. Could this be achieved using the same the same traversals .

           $('#fieldset_QCNew table tbody tr td:nth-child('+index+')').css("display","none");

Here is what you need:

$(function() {
    $('td').on('click', function() {
        $(this).closest('table').find('td').not(this).toggle();
    });
});

NOTE: If you'd like the cells to maintain their positions then using .css("visibility", "hidden") rather than .hide() or toggle -- which use .css("display", "none") -- would achieve that.

$(function() {
    $('td').on('click', function() {
        $(this).closest('table').find('td').not(this).toggle();
    });
});
