Setelah browsing cari cara membuat widget tidak menggunakan Jquery yang bisa menyebabkan render blocking js akhirnya ketemu juga Tutorialnya dari Mas Adhy Suryadi. Sobat blogger di postingan kali ini saya akan berbagi sekaligus menjawab pertanyaan dari Mas Ade si empunya Blog Kuliner Jalanan.

Sebenarnya saya bukan alergi dengan Jquery tapi sering timbul masalahnya itu loh kadang menyebabkan masalah render blocking js di blog di postingan ini akan dibahan Cara Membuat Animated News Ticker di Recent Post Blogger dengan menggunakan Javascript jadi lumayan bisa mengurangi render blocking js tadi. 

Dan akhirnya ketemu juga tampilannya seperti Gambar diatas, News Ticker Recent post yang tampilannya animasi saat mengetik, bagi sobat sobat yang ingin mencobanya silahkan simak berikut ini.

Kode Javascript

Silahkan sobat salin dan simpan kode Javascript ini lalu letakkan tepat diatas kode </body>

Perhatikan kode yang ditandai, silahkan rubah

• http://blogsobat.blogspot.com dengan alamat url blog sobat
• silahkan rubah Blogger dengan nama label yang sobat mau
• Jika ingin menampilkan featured Post maka dihapus saja kode /-/Blogger
• Kode  displayTime : 5000 fungsinya untuk mengatur kecepatan loading title postkalau mau ditampilkan lebih lama di rubah saja angkanya lebih besar.
• Kode numResults : 10 fungsinya untuk menampilkan berapa banyak post yang akan ditampilkan

Kode CSS

Selanjutnya silahkan sobat salin kode CSS ini letakkan diatas kode ]]></b:skin> atau </style>

.hot-title,.recent-news{font-family: 'Roboto', sans-serif;box-sizing:border-box;height:40px}
.recent-news{width:100%;background:#ddd;padding:0 20px 0 0;margin:0;line-height:40px;-moz-box-sizing:border-box;-webkit-box-sizing:border-box;overflow:hidden;}
.hot-title{display:inline;float:left;width:130px;height:40px;line-height:40px;margin-top:0px;background:#222;font-size:16px;font-weight:500;color:#fff;padding-left:20px;-moz-box-sizing:border-box;-webkit-box-sizing:border-box}
.gfg-root{width:100%;height:auto;position:relative;margin:0 auto}
.gfg-title{display:none}
.gfg-entry{display:block;padding:0;margin:0 0 0 140px;height:40px;line-height:40px;}
.gf-title a{text-transform:capitalize;text-decoration:none;color:#333;font-size:16px;font-weight:300;white-space:nowrap;overflow:hidden;text-overflow:ellipsis;display:block;width:100%;animation: type 8s steps(60, end)}
.gf-author,.gf-snippet,.gf-spacer,.gfg-list,.gfg-subtitle{display:none!important}
.gf-relativePublishedDate{display:inline;float:right;margin-top:-40px;font-size:16px;font-weight:300;}
#feedGadget{font-size:16px;font-weight:300;}
@keyframes type{
  from { width: 0; }
}
@media screen and (max-width:800px){
    .gf-relativePublishedDate{display:none!important}
}
@media screen and (max-width:480px){
    .recent-news{display:none!important}
}

Perhatikan kembali kode yang ditandai itu adalah jenis font yang dipakai kalau sobat mau ganti silahkan sesuaikan saja.


Kode HTML
Nah ini langkah terakhir setelah kode Javascript dan CSS terpasang, silahkan sobat salin dan letakkan kode HTML ini letakkan bebas dimana sobat nantinya akan menampilkan news ticker-nya bisa diletakkan di atas atau pun di bawah header.

    <div class="recent-news">
    <div class="hot-title">Recent News:</div>
<div id="feedGadget">&amp;nbsp; Loading...</div>
    </div>

Yang perlu diperhatikan adalah kode-kode script diatas itu teritegrasi dengan Jsapi atau Google API Loader hal ini tergantung Template blog yang sobat gunakan kalau di template yang saya pakai ini tidak perlu menggunakan.

Nah jika ini terjadi di blog sobat News Ticker-nya tidak bisa tampil atau jalan saya ada solusinya silahkan sobat salin dan letakkan kode script dibawah ini simpan di atas kode </body>.

<script>
  //<![CDATA[
  (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = '//www.google.com/jsapi'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();
//]]>
</script>

Dan...Selesai, Selamat Mencobanya.
