Back to top 버튼 달기

사용자가 웹페이지에서 스크롤을 내리다가 다시 위로 올라가기 편하게 달아주는 것이 'Back to Top' 버튼이다.

코드를 찾아보다가 간편하게 한 덩어리로 갖다 붙일 수 있는 코드들이 있는 곳을 발견했다.
http://www.scrolltotop.com/

그곳에서 좀 괜찮아 보이는 몇개를 가져와봤다. 간단하게 붙일 수 있는 Back to Top 버튼 코드들인데, 웹페이지 소스에서 </html>앞에만 붙여주면 된다.

단점은 jquery.js를 불러들이기 때문에 만약 해당 웹페이지에서 어짜피 jquery.js를 로딩하고 있다면 크게 상관없겠지만 기존에는 jquery.js를 로딩하지 않았는데 이 버튼을 달기 위해 로딩한다면 그만큼 (얼마안되지만) 사용자들의 데이터를 낭비하는 꼴이 될 수 있다.

두번째 단점은 이 Back to Top 버튼의 위치가 브라우저의 우측 맨 하단인데, 아이폰 사파리의 경우 우측 맨 하단을 누르면 자동으로 사파리 메뉴가 올라오게 되기 때문에 Back to Top버튼을 먹히게 하려면 두번 터치해야 하는 부분이다.

하지만 그런대로 간단하게 쓸만하기 때문에 이 블로그에도 이 버튼 중 하나를 적용시켜 보았다.
