Smooth Scroll Back To Top Javascript With Animation
Sudah banyak yang sharing cara membuat tombol back to top untuk blog, namun kebanyakan menggunakan jquery. Nah kali ini saya akan membagikan cara membuat back to top dengan gerakan smooth scroll menggunakan pure javascript ditambah css animasi untuk kemunculannya.

Ada 2 macam smooth scroll back to top javascript with animation ini, yang pertama menggunakan tambahan javascript untuk show hide on scroll dengan animasi bounceIn untuk memperhalus munculnya tombol, dan yang kedua tidak menggunakan javascript show hide on scroll, namun hanya menggunakan css animasi bounceIn left untuk kemunculan tombolnya ketika halaman dibuka seperti animasi gif di bawah ini.

Dengan show hide on scroll.

Silahkan simpan kode css ini di atas kode </head>. Tombol hanya ditampilkan di halaman postingan dan dihilangkan di perangkat mobile.


<b:if cond='data:blog.isMobileRequest == &quot;false&quot; and data:blog.pageType == &quot;item&quot;'>
<style type='text/css'>
#backtotop{position:fixed;bottom:20px;right:20px;cursor:pointer}
.ani-dur{-webkit-animation-fill-mode:both;-moz-animation-fill-mode:both;-ms-animation-fill-mode:both;animation-fill-mode:both;-webkit-animation-duration:1s;-moz-animation-duration:1s;-ms-animation-duration:1s;animation-duration:1s}
@-webkit-keyframes bounceIn{0%{opacity:0;-webkit-transform:scale(.9)}
100%{-webkit-transform:scale(1)}}
@-moz-keyframes bounceIn{0%{opacity:0;-moz-transform:scale(.9)}
100%{-moz-transform:scale(1)}}
@-ms-keyframes bounceIn{0%{opacity:0;-ms-transform:scale(.9)}
100%{-ms-transform:scale(1)}}
@keyframes bounceIn{0%{opacity:0;transform:scale(.9)}
100%{transform:scale(1)}}
.ani-name{-webkit-animation-name:bounceIn;-moz-animation-name:bounceIn;-ms-animation-name:bounceIn;animation-name:bounceIn}
</style>
</b:if>

Simpan javascript di bawah ini di atas kode </body>


<b:if cond='data:blog.isMobileRequest == &quot;false&quot; and data:blog.pageType == &quot;item&quot;'>
<script>
//<![CDATA[
function resetScroller(e){var o=window.pageYOffset,n=document.getElementById(e).offsetTop,r=setTimeout("resetScroller('"+e+"')",speed);o>n?(scrollY=o-distance,window.scroll(0,scrollY)):clearTimeout(r)}var appended=!1,bookmark2=document.createElement("div");bookmark2.id="backtotop",bookmark2.innerHTML='<span class="ani-dur ani-name" onclick="return false;" onmousedown="resetScroller(&quot;header-wrapper&quot;);"><i class="fa fa-chevron-circle-up fa-3x"></i></span>',onscroll=function(){var e=document.documentElement.scrollTop||document.body.scrollTop;e>600?appended||(document.body.appendChild(bookmark2),appended=!0):appended&&(document.body.removeChild(bookmark2),appended=!1)};var scrollY=0,distance=40,speed=24;
//]]>
</script>
</b:if>

Silahkan ganti kode header-wrapper jika ada tag id yang lebih atas dari itu. Angka 600 adalah ketiggian scroll untuk memunculkan tombolnya.

Silahkan ganti kode header-wrapper jika ada tag id yang lebih atas dari itu.
