Membuat Breaking News Menarik Dibawah Navigasi Menu

Written By Direktur Iklan on Senin, 26 Desember 2011 | 05.09

Pada artikel kali ini saya akan menjelaskan bagaimana membuat breaking news atau berita berjalan yang biasanya terdapat di bawah navigasi menu pada sebuah blog atau biasa disebut newsticker. Banyak sudah artikel yang membahas mengenai newsticker ini di internet, misalnya dengan menambah efek marquee sehingga teks tersebut dapat berjalan, tapi kali ini saya akan menjelaskan cara memasang breking news dengan sentuhan jQuery sehingga hasilnya akan lebih menarik dan yang pasti dapat mempercatik blog anda.

news ticker Download Disini

Pertama kali saya melihat tampilan breaking news ini pada template Sporty Magazine 2 buatan Borneo Template, waktu itu template masih berbayar sekarang sepertinya sudah gratis di download. Disini saya akan memodifikasi sedikit tampilannya sehingga tampilannya seperti tampak pada gambar diatas, demonya anda bisa lihat disini. (http://martin-big.blogspot.com)

Ternyata cara memasangnya sangat gampang sekali, dan jika Anda tertarik berikut ini langkah-langkah untuk membuatnya :
  1. Login ke blogger dengan akun anda
  2. Kemudian klik Tata Letak > pilih Edit HTML
  3. Jangan lupa backup dulu template anda dengan mengklik Download Template Lengkap.
  4. Letakkan kode berikut di atas kode ]]></b:skin>
    /* News Ticker Wrapper
    ---------------------------------------------*/
    .newspic {background:#000 url(http://4.bp.blogspot.com/-vqHATrTDsY8/TvguMe2lBTI/AAAAAAAAEUk/L8UwRygGp9s/s1600/news.gif) no-repeat top left;width:970px;margin:0 auto;padding:0 auto;height:32px;color:#fff;}
    .news {width: 970px;margin:0 auto;padding:0 auto;line-height: 1.4em;text-align:left;font-family:Arial;font-size:11px;color:#fff;overflow:hidden;clear:both;}
    .news a:link, .news a:visited{color:#fff;text-decoration:none;}
    .news a:hover {color:#ddd;text-decoration:underline;}
  5. Masih dalam dalam posisi Edit HTML. Sekarang letakkan kode berikut ini di atas kode </head>

    </script>
    <style type='text/css'>
    .titlefield{ /*CSS for RSS title link in general*/
    text-decoration: none;}
    .labelfield{ /*CSS for label field in general*/
    color:#aaa;font-size: 100%;}
    .datefield{ /*CSS for date field in general*/
    color:#aaa;font:normal 14px Arial;text-transform:none;}

    #example1 a:hover {color:#C8D3F2;text-decoration:none;}
    </style>
  6. Kemudian cari kode dibawah ini, atau kode yang biasa dipakai untuk meletakkan navigasi menu
    <div class='menu horizontal'>
    ...........................................
    ...........................................
    </div>
  7. Jika sudah ketemu letakkan kode berikut tepat dibawah kode </div> yang dipakai untuk menutup kode navigasi menu pada template Anda.
    <div class='newspic'>

    <div style='float:left;width:780px;padding:6px 0 6px 180px; position:relative; overflow:hidden;'>
    <script type='text/javascript'>
    var cssfeed=new gfeedrssticker(&quot;example1&quot;, &quot;example1class&quot;, 4000, &quot;_new&quot;)
    cssfeed.addFeed(&quot;Download Disini&quot;, &quot;http://Download Disini.blogspot.com/feeds/posts/default&quot;) //Specify &quot;label&quot; plus URL to RSS feed
    cssfeed.displayoptions(&quot;date&quot;) //show the specified additional fields
    cssfeed.setentrycontainer(&quot;div&quot;) //Wrap each entry with a DIV tag
    cssfeed.filterfeed(10, &quot;date&quot;) //Show 10 entries, sort by date
    cssfeed.entries_per_page(1)
    cssfeed.init()
    </script>
    </div>
    <div style='clear:both;'/>
    </div>
  8. Ganti URL yang saya beri warna merah dengan URL blog anda dan jika blog anda masih baru newsticker ini biasanya tidak mau jalan karena google belum mengenal feed di blog Anda. Solusinya gampang Anda mesti buat API key sendiri di googlecode, atau langsung saja disini. Masukkan URL blog anda, kemudian ganti kode javascript paling atas pada langkah nomer 5 dengan kode yang barusan dapet dari googlecode (bener nggak sih ngomongku...... )
  9. Langkah terakhir save/simpan, lihat dibawah navigasi menu anda, kalau cara memasangnya sudah benar pasti akan muncul breaking news itu.
Agar lebih ramping simpan kode javascript newsticker diatas (no.5) di tempat penyimpanan googlecode Anda. Mudah kan? Jika ada yang mau ditanyakan silahkan isi pada kolom komentar dibawah. Selamat mencoba dan semoga bermanfaat.
