Question

I want to export my html table to csv file. I have found java script as per follow. Table is getting downloaded but data are not there in the table. Can anyone tell me where is the problem. exact code is working here http://jsfiddle.net/terryyounghk/KPEGU/

$(document).ready(function () {

        function exportTableToCSV($table, filename) {

            var $rows = $table.find('tr:has(td)'),

            // Temporary delimiter characters unlikely to be typed by keyboard
            // This is to avoid accidentally splitting the actual contents
            tmpColDelim = String.fromCharCode(11), // vertical tab character
            tmpRowDelim = String.fromCharCode(0), // null character

            // actual delimiter characters for CSV format
            colDelim = '","',
            rowDelim = '"\r\n"',

            // Grab text from table into CSV formatted string
            csv = '"' + $rows.map(function (i, row) {
                var $row = $(row),
                $cols = $row.find('td');

                return $cols.map(function (j, col) {
                    var $col = $(col),
                    text = $col.text();

                    return text.replace('"', '""'); // escape double quotes

                }).get().join(tmpColDelim);

            }).get().join(tmpRowDelim)
            .split(tmpRowDelim).join(rowDelim)
            .split(tmpColDelim).join(colDelim) + '"',

            // Data URI
            csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);

            $(this)
            .attr({
                'download': filename,
                'href': csvData,
                'target': '_blank'
            });
        }

        // This must be a hyperlink

        $(".export").on('click', function (event) {
            // CSV
            exportTableToCSV.apply(this, [$('#dvData>table'), 'export.csv']);

            // IF CSV, don't do event.preventDefault() or return false
            // We actually need this to be a typical hyperlink
        });
    });
