Memasang Newsticker(Artikel berjalan) via Google API

MAjalahAsik.com - Artikel tutorial kali ini adalah tentang bagaimana cara membuat Newsticker Via Google API .

Langkah pertama, Anda harus mendapatkan kode API key blog Anda terlebih dahulu. Caranya mudah, silahkan menuju ke halaman API key Google Code, lalau masukkan alamat blog Anda dan tekan Generate API key. Maka secara otomatis API key Anda akan muncul. Contohnya seperti di bawah ini :

ABQIAAAAUMsU2d40bO1-m8DeADFRexSdupW3UblI5-uymDD3tToJ_XzTzRTHuyVgfpokD8LoL9kqMyn5QmrKKA

Setelah kode API key sudah Anda dapatkan, silahkan masuk ke halaman tab edit HTML halaman blog Anda (tidak perlu dicentang). Lalu masukkan kode di bawah ini tepat di atas tag </head> :

<script src='http://www.google.com/jsapi?key=your-API-key'/>

<script type='text/javascript'>

</style>

Setelah itu, ganti tulisan berwarna merah Your API Key dengan alamat API key Anda, dan tulisan berwarna biru dengan lebar widget yang Anda inginkan. Langkah berikutnya, buka tab elemen halaman blog Anda, lalu tambahkan gadegt HTML/Java Script dengan kode di bawah ini :

<script type="text/javascript">
var cssfeed=new gfeedrssticker("example1", "example1class", 4000, "_new")
cssfeed.addFeed("Judul", "http://your-url-link/feeds/posts/default") //Specify "label" plus URL to RSS feed
cssfeed.displayoptions("date") //show the specified additional fields
cssfeed.setentrycontainer("div") //Wrap each entry with a DIV tag
cssfeed.filterfeed(10, "date") //Show 10 entries, sort by date
cssfeed.entries_per_page(1)
cssfeed.init()
</script>

Berikutnya, ganti tulisan yang berwarna merah dengan judul dan alamat url link blog Anda. Selesai dan silahkan lihat hasilnya.
