如何获取第一行并将其附加到jQuery DataTables？

Question

I'm getting my first row:

var lFirstRow = self.table.fnGetData($('#' + self.idResultGrid() + ' tbody tr:eq(0)')[0]);

And trying to append to my table:

$('#' + self.idResultGrid() + ' tbody').append(lFirstRow);

Doesn't work, any idea why?

Answer 1

Generally, you should avoid manipulating the table directly unless really necessary and use appropriate API methods.

SOLUTION

Use fnAddData (DataTables 1.9) or row.add() (DataTables 1.10) to add data to the table:

var lFirstRow = self.table.fnGetData($('#' + self.idResultGrid() + ' tbody tr:eq(0)'));
self.table.fnAddData(lFirstRow);
