Read More with jQuery Like Expandable Posts with Peekaboo

Sebenarnya mosting artikel berikut rada-rada kebelinger juga. Soalnya kebanyakan blogger sudah pada pakai trik read more yang menggunakan tag waktu memosting <span class="fullpost"> Tapi tidak apa-apa, siapa tauk ada yang mau pakai lah :D Kali ini Beben si bloglang anu ganteng kalem tea akan berbagi bagaimana cara membuat read more menggunakan jQuery ;;) Untuk lebih jelasnya silahkan lihat live demo ini http://www.jsfiddle.net/devcurry_com/sxXn2/ dan original article http://www.devcurry.com/2010/12/add-read-more-link-using-jquery.html Kalau pada postingan aslinya meletakan script sebelum tag </head> tapi setelah Beben praktekan disimpan sebelum tag </body> berjalan dengan baik juga kok, atur-atur saja deh yah ;))

Pemakaian ketika akan memosting sobat hanya tinggal melakukan tag

<div class="readmore">

... ISI POSTINGAN ...

</div>Letakan seluruh script jQuery berikut sebelum tag </head> atau </body>
