Cara Membuat Tombol Back To Top di Blog

       Terkadang jika kita sudah membaca sebuah postingan blog yang panjang, kita ingin kembali lagi ke bagian atas, tapi akan memakan waktu lama jika hanya dgn scrolling. Oleh karena itu kalian bisa menggunakan trik ini untuk mempermudah visitor blog anda berpindah ke bagian paling atas postingan.

1. Masuk ke akun blogger anda

2. Pergi ke tata letak -> tambah gadget -> html/javascript

3. Masukkan script ini ke kotak yang besar (kotak judul dikosongi saja)

<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: '<img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgWX2RC1lvqdk_t2D_G9XkFqkXJax6jpDCUETQFq_bJmWyuLeUNK0UeMvdIXGP52yZPyuQcy3N6st_8Uf2w4uHBgAreufcHTs3H91HyxgslBoSmUKnNrjhDY8RE31TwRYaXLaP9T7oB-2Vc/s1600/navigate-up-icon.png" />', //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.$control.css({opacity:0}) //hide control immediately after clicking it var dest=isNaN(this.setting.scrollto)? this.setting.scrollto : parseInt(this.setting.scrollto) if (typeof dest=="string" && jQuery('#'+dest).length==1) //check element set by string exists dest=jQuery('#'+dest).offset().top else dest=0 this.$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 mainobj.togglecontrol() $('a[href="' + mainobj.anchorkeyword +'"]').click(function(){ mainobj.scrollup() return false }) $(window).bind('scroll resize', function(e){ mainobj.togglecontrol() }) }) } } scrolltotop.init() </script>

Text yang berwarna merah bisa anda ganti dengan url gambar yang lain

4. Klik "simpan"

5. Nah sekarang anda check blog anda, maka tombol back to top akan muncul di pojok kanan bawah. Dengan begitu jika di klik akan scroll otomatis ke atas.

Selamat mencoba :D
