Question

how remove html table rows after 2nd row?
if in table have 5 row, 1 and 2 are safe, 3,4,5 must be remove

Answer 1

Use detach() instead of remove()

var myremovedElems = $("#table tr:gt(1)").detach();

The .detach() method is the same as
.remove(), except that .detach()
keeps all jQuery data associated with
the removed elements. This method is
useful when removed elements are to be
reinserted into the DOM at a later
time.
