    //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).

    state: {isvisible:false, shouldvisible:false},
    scrollup:function(){
    if (!this.cssfixedsupport) //if control is positioned using JavaScript
    this.$control.css({opacity:0}) //hide control immediately after clicking it
    var dest=isNaN(this.setting.scrollto)? this.setting.scrollto : parseInt(this.setting.scrollto)
    if (typeof dest=="string" && jQuery('#'+dest).length==1) //check element set by string exists
    dest=jQuery('#'+dest).offset().top
    else
    dest=0
    this.$body.animate({scrollTop: dest}, this.setting.scrollduration);
    },
    keepfixed:function(){
    var $window=jQuery(window)
    var controlx=$window.scrollLeft() + $window.width() - this.$control.width() - this.controlattrs.offsetx
    var controly=$window.scrollTop() + $window.height() - this.$control.height() - this.controlattrs.offsety
    this.$control.css({left:controlx+'px', top:controly+'px'})
    },
    togglecontrol:function(){
    var scrolltop=jQuery(window).scrollTop()
    if (!this.cssfixedsupport)
    this.keepfixed()
    this.state.shouldvisible=(scrolltop>=this.setting.startline)? true : false
    if (this.state.shouldvisible && !this.state.isvisible){
    this.$control.stop().animate({opacity:1}, this.setting.fadeduration[0])
    this.state.isvisible=true
    }
    else if (this.state.shouldvisible==false && this.state.isvisible){
    this.$control.stop().animate({opacity:0}, this.setting.fadeduration[1])
    this.state.isvisible=false
    }
    },
    init:function(){
    jQuery(document).ready(function($){
    var mainobj=scrolltotop
    var iebrws=document.all
    mainobj.cssfixedsupport=!iebrws || iebrws && document.compatMode=="CSS1Compat" && window.XMLHttpRequest //not IE or IE7+ browsers in standards mode
    mainobj.$body=(window.opera)? (document.compatMode=="CSS1Compat"? $('html') : $('body')) : $('html,body')
    mainobj.$control=$('<div id="topcontrol">'+mainobj.controlHTML+'</div>')
    .css({position:mainobj.cssfixedsupport? 'fixed' : 'absolute', bottom:mainobj.controlattrs.offsety, right:mainobj.controlattrs.offsetx, opacity:0, cursor:'pointer'})
    .attr({title:'Scroll Back to Top'})
    .click(function(){mainobj.scrollup(); return false})
    .appendTo('body')
    if (document.all && !window.XMLHttpRequest && mainobj.$control.text()!='') //loose check for IE6 and below, plus whether control contains any text
    mainobj.$control.css({width:mainobj.$control.width()}) //IE6- seems to require an explicit width on a DIV containing text
    inobj.togglecontrol()
    $('a[href="' + mainobj.anchorkeyword +'"]').click(function(){
    mainobj.scrollup()
    return false
    })
    $(window).bind('scroll resize', function(e){
    mainobj.togglecontrol()
    })
    })
    }
    }
    scrolltotop.init()
    </script>
    Terakhir Save dan Lihat hasilnya

    Gambar icon Back to Top nya bisa sobat ganti sendiri kalau tidak suka bisa searching di google dengan keyword "back to top" lalu uploud gambarnya dan copas kodenya ke script yang berwarna "merah" tsb.

    Semoga Bermanfaat
