Jquery iterating table

I am using following code to iterate table rows with id

$('#resultingTableOfSaveDataJS tr').each(function () { //line 1
    var rowID = $(this).id.charAt(6); //line 2
    if (rowID == currentID) { //line 3
        $('#this td').slice(diff); //line 4
    }
});

At line 2 i am trying to get the character at 6th position of my each row's id. But I am getting a Undefined error at line 2.

Please help me to get this code right.

each() has parameters that you can use:

$('#resultingTableOfSaveDataJS tr').each(function(index, elem){
    var rowID = elem.id.charAt(6);
    if (rowID == currentID){
         $('td', elem).slice(diff);
    }
});

You're using DOM methods on jQuery objects. To get the id from a jQuery object:

$(this).attr('id').charAt(6);

Or:

$(this).prop('id').charAt(6);

Without jQuery (and JQuery is needless, and over-expensive for this), using the DOM/'plain' JavaScript:

this.id.charAt(6);

It's either

$(this).attr('id').charAt(6); // jQuery

Or

this.id.charAt(6); // non-jQuery
