Namun beberapa pengguna, khususnya yang belum (bukan tidak) paham dengan script HTML, akan sedikit ragu, jangan-jangan script tersebut malah membuat tampilan atau load blognya semakin lambat. Hal ini sebenarnya bisa diantisipasi dengan melakukan back up terlebih dahulu jika hendak melakukan perubahan.
Apapun itu, sebenarnya ada cara paling mudah untuk memasang script tombol back to top di blogspot.
Bagi Anda yang belum mengerti apa itu tombol back to top atau kembali ke atas adalah tombol sorcut yang disediakan di bilah kanan blog. Tombol ini akan memudahkan pembaca untuk kembali ke atas halaman, jika telah jauh melakukan scroll ke bawah. Jadi dengan menekan tombol ini, pengunjung tak perlu lagi menekan scroll ke atas.
Lalu bagaimana memasang tombol back to top ini dengan mudah?
Caranya dengan mengcopy script berikut ke sidebar blog Anda. Lakukan seperti menambahkan script lainnya di halaman dasboard. Klik Tata Letak, lalu pilih Tambahkan Gadget dan pilih THML/JavaScript.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" >
var scrolltotop={
//startline: Integer. Number of pixels from top of doc scrollbar is scrolled before showing control
//scrollto: Keyword (Integer, or "Scroll_to_Element_ID"). How far to scroll document up when control is clicked on (0=top).
setting: {startline:100, scrollto: 0, scrollduration:1000, fadeduration:[500, 100]},
controlHTML: 'Paste URL Back To Top Anda Disini" />', //HTML for control, which is auto wrapped in DIV w/ ID="topcontrol"
controlattrs: {offsetx:5, offsety:5}, //offset of control relative to right/ bottom of window corner
anchorkeyword: '#top', //Enter href value of HTML anchors on the page that should also act as "Scroll Up" links
state: {isvisible:false, shouldvisible:false},
scrollup:function(){
if (!this.cssfixedsupport) //if control is positioned using JavaScript
this.$control.css({opacity:0}) //hide control immediately after clicking it
var dest=isNaN(this.setting.scrollto)? this.setting.scrollto : parseInt(this.setting.scrollto)
if (typeof dest=="string" && jQuery('#'+dest).length==1) //check element set by string exists
