Jquery get values of all checked rows in table gridview

Answer 1

You should do

$(document).ready(function() {
    var tableControl= document.getElementById('mytable');
   var arrayOfValues = [];
    $('#jqcc').click(function() {
        $('input:checkbox:checked', tableControl).each(function() {
            arrayOfValues.push($(this).closest('tr').find('td:last').text());
        }).get();
    });
});

arrayOfValues will hold the text inside the last td.

EDIT of course you could also use map

$(document).ready(function() {
    var tableControl= document.getElementById('mytable');
   var arrayOfValues = [];
    $('#jqcc').click(function() {
          arrayOfValues =  $('input:checkbox:checked', tableControl).map(function() {
            return $(this).closest('tr').find('td:last').text();
        });
    });
});
