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();
});
});
});
