[jQuery] reverse, each 거꾸로 읽어서 삭제

# [jQuery] reverse, each 거꾸로 읽어서 삭제.

1. reverse

- 테이블의 tr을 뒤에서 읽어면서 삭제 처리함.

2. each

- tr 수만큼 반복.

3. remove

- 첫번째 tr은 삭제하지 않음.

$($("#tesTable tr").get().reverse()).each( function() {

var num = $(this).attr("id").replace("tr", "");

if(num>1) {

$(this).attr("id", "tr" + num).remove();

} 

});
