Tutorial kali ini saya akan membahas bagaimana membuat slider
Carousel otomatis berdasarkan label. Prinsip kerja dari slider ini sama
seperti pada slider otomatis berdasarkan kategori. Anda tinggal mengganti
dengan label anda dan slider ini akan bekerja sesuai dengan label yang anda
masukkan. Slider Carousel yang saya buat kali ini sangat sederhana dan hanya menggunakan Carousellite script
tanpa menambahkan efek easing dan mousewheel.
Cara pemasangannyapun sangat mudah, jika anda sudah pernah mempraktekkan
artikel saya terdahulu yang berjudul membuat slider otomatis berdasarkan
kategori tertentu, tutorial kali ini terasa sangat mudah, karena
langkah-langkah pembuatannya hampir sama. Langsung saja di bawah ini
langkah-langkah untuk membuatnya :
- Login ke blogger dengan akun Anda
- Setelah itu pilih blog yang ingin anda tambahkan slider ini.
- Masuk ke template >> Edit HTML, kemudian centang expand widget templates
- Untuk berjaga-jaga agar tidak terjadi kesalahan dalam pengeditan nantinya, backup dulu template anda.
- Setelah semua langkah diatas anda lakukan, letakkan kode berikut ini diatas kode ]]></b:skin> :

Perhatikan kode
warna biru diatas, itu
adalah lebar dan tinggi slider pada demo yang saya buat, silahkan Anda
sesuaikan dengan ukuran template Anda.

Keterangan :
Perhatikan URL script
warna merah diatas, itu adalah kode script jQuery.min.js seri
terbaru yang saya gunakan untuk membuat slider ini. Jika pada template Anda
sudah terdapat jQuery.min.jswalaupun serinya berbeda, kode warna merah
diatas tidak perlu lagi Anda masukkan. Cukup satujQuery.min.js yang
ada di template, terserah mau seri berapa, kalau bisa versi yang terbaru.
Sedangkan kode
warna biru : 15 adalah jumlah
slider yang ditampilkan. Dan news adalah label
yang ditampilkan pada slider nantinya (Ingat besar kecil huruf harus sama
dengan label yang sudah Anda buat).
- Langkah selanjutnya adalah memanggil slider tersebut agar muncul di blog kita. Cari kode <div id='main-wrapper'>, kemudian letakkan kode berikut ini diatasnya :
<b:if
cond='data:blog.pageType != "item"'>
<div id='carousel'>
<div id='previous_button'/>
<div class='container'>
<script>
<div id='carousel'>
<div id='previous_button'/>
<div class='container'>
<script>
document.write("<script
src=\"/feeds/posts/default/-/"+label1+"?max-results="+numposts1+"&orderby=published&alt=json-in-script&callback=showrecentposts\"><\/script>");
</script>
<div class='clear'/>
</div>
<div id='next_button'/>
</div>
<script type='text/javascript'>
(function($) { $(document).ready(function(){
$("#carousel .container").jCarouselLite({
auto:4000,
scroll: 1,
speed: 800,
visible: 5,
start: 0,
circular: true,
btnPrev: "#previous_button",
btnNext: "#next_button"
});
})})(jQuery)
</script>
</b:if>
<div class='clear'/>
</div>
<div id='next_button'/>
</div>
<script type='text/javascript'>
(function($) { $(document).ready(function(){
$("#carousel .container").jCarouselLite({
auto:4000,
scroll: 1,
speed: 800,
visible: 5,
start: 0,
circular: true,
btnPrev: "#previous_button",
btnNext: "#next_button"
});
})})(jQuery)
</script>
</b:if>
Kode diatas bisa juga
anda letakkan dibawah atau diatas navigasi menu Anda atau bisa juga diletakkan
diatas footer.
- Langkah terakhir, save templates dan lihat hasilnya. Jika Anda ikuti langkah diatas dengan benar, slider Carousel itu akan muncul di blog Anda.
Sangat mudah ya, anda tinggal ikuti langkah-langkah diatas dan baca dengan
teliti jangan terburu-buru, Jika masih ada yang kurang jelas silahkan
tinggalkan pesan pada kotak komentar yang ada di bawah. Itu tadi tutorial
singkat tentang bagaimana cara membuat slider Carousel otomatis
berdasarkan kategori atau label kali ini, selamat mencoba dan semoga
bermanfaat.
