Disini saya ingin berbagi bagaimana cara membuat featured post slide random lengkap dengan gambar. Slide random dimaksudkan gambar ataupun posts yang ditampilkan nantinya akan berupa acak.
Bagi yang ingin memasangnya bisa ikuti tutorial berikut ini. Ini juga saya pakai karena dianggap baik dan berguna untuk saya sendiri. Featured posts ini saya dapatkan dari komunikasipraktis.com
Berikut langkah - langkahnya :
Cara membuat featured posts slide
1. Pastikan di template blog sobat sudah ada kode jQuary
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js' type='text/javascript'/>Jika belum silahkan tempelkan di atas kode </head>
2. Langkah selanjutnya tempelkan kode CSS dan javasScript tempatkan pula di atas kode </head>

//]]>
</script>
<!-- Featured Random Posts Slider End -->
3. Buat kode HTML untuk posisi wiget
Simpan di bawah kode <div id='main-wrapper'> or similar with that code. Pokoknya, posisinya di bawah Navigasi Menu atau di atas Blog Post.<!-- Featured Random Post Slider Start -->
<b:if cond='data:blog.pageType != "static_page"'>
<b:if cond='data:blog.pageType != "item"'>
<div id='top-main'>
<b:section class='main' id='top-main1' preferred='yes'>
</b:section>
</div>
</b:if></b:if>
<!-- Featured Random Post Slider End -->
4. Simpan template sobat
Langkah berikutnya untuk Membuat Featured Post Thumbnail di Halaman Depan Blog5. Koden HTML/JavaScript untuk Pasang Widgetnya
- Layout > Add a Gadget > HTML/Javascript- Copas kode berikut ini ke dalam konten. Judul kosongkan!
<div id="randompostxx"></div>Catatan :
<script type='text/javascript'>
//<![CDATA[
$(document).ready(function () {
RandomPost({
MaxPost:4,
RandompostActive:false,
idcontaint:"#randompostxx",
ImageSize:200,
tagName:false
});
});
//]]>
</script>
Jika ingin memasang untuk label silahkan ganti tagName:false dengan tagName:nama label sobat
MaxPost juga bisa dirubah sesuai kebutuhan sobat.
Dan jangan lupa gunakan gunakan tag kondisional pada wiget agar tampil hanya di halaman depan saja.
Berikut langkahnya : Cara menempatkan tag kondisional pada wiget
Misal, kita akan menampilkan sebuah widget hanya di halaman depan.
- Template > Edit HTML
- Temukan kode widget di dalam template yang diawali dengan kode <b:widget ... > dan diakhiri dengan </b:widget>
- Masukkan kode <b:if cond='data:blog.url == data:blog.homepageUrl'> setelah kode <b:includable id='main'> dan kode penutup </b:if> sebelum kode penutup widget/sebelum kode </b:includable>
Demikianlah langkahnya semoga berhasil dengan baik.
