如何选择要导出为CSV文件的列？我尝试隐藏不需要添加到CSV文件中的列，但它仍然获取隐藏的数据。我在这里使用codeigniter和jquery将表格HTML导出到CSV文件中。我这里不使用数据库只是CSV文件和表格html。
下面是我导出CSV文件的代码。这是在VIEW
$(document).ready(function () {
function exportTableToCSV($table, filename) {
var $rows = $table.find('tr:has(td)'),
tmpColDelim = String.fromCharCode(11),
tmpRowDelim = String.fromCharCode(0),
colDelim = '","',
rowDelim = '"\r\n"',
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) + '"',
csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csv);
$(this)
.attr({
'download': filename,
'href': csvData,
'target': '_blank'
});
}
$(".export").on('click', function (event) {
exportTableToCSV.apply(this, [$('#dvData>table'), 'pdw_table.csv']);
});
});

答案 0 :(得分：0)
尝试将一些特殊属性或类推送到您不想导出的列，例如，推送类“hidden_col” 然后，改变
$cols = $row.find('td');
到
$cols = $row.find('td:not(.hidden_col)');
