Make Label/Category Use HTML5 Canvas Tag Cloud

Sebelumnya Koben mau kasih tau, jangan dipakai hack make error page 404 100% for blogger! Karena ternyata kode yang dihapusnya itu termasuk kode buat menampilkan label/kategori juga #-o Maaf maaf Koben tidak tahu :D Saya ngeuh ketika mempraktekan tutorial tentang HTML5 Canvas Tag Cloud.
Sebelumnya postingan label/catefory cloud for blogger with jQuery dan flash animated category/label cloud for blogger sama² menampilkan efek cloud-cloud :p Ada satu lagi deng label/kategori with cumulus technique :d
TagCanvas atau Tag Canvas merupakan JavaScript dimana hasil tampilan akan berupa cloud serta berbasis tag HTML5.

Canvas Tag Cloud kreasi goat1000 terdapat 2 versi, versi pertama yaitu tagcanvas murni javascript & tagcanvas plugin jQuery versi. Koben disini akan berbagi cara bagaimana memasukan tag-canvas jQuery plugins version ke dalam blog!
Langkah pertama yang musti dilakuin adalah Download Full Template. Selanjutnya Expand Widget Templates
Kemudian download script jquery.tagcanvas.js version 1.11.1 or [Minified] pilih salah satu saja!
Letakkan script hasil download dibawah jQuery inti, atau bisa juga diatas/sebelum tagging </body>
Template dalam keadaan Expand, carilah kode berikut<b:widget id='Label1' locked='false' title='Labels' type='Label'>

demo

Kode tersebut merupakan code label pada blogger. Jadi jika sobat belum punya widget label/category buat dulu sana. Karena tutorial berikut berjalan jika ada itu :)) Bila sudah ketemu letakkan syntax HTML berikut<canvas height='300' id='myCanvas' width='300'>tepat diatas code<b:if cond='data: display == &quot;list&quot;'>
<b:widget id='Label1' locked='false' title='Labels' type='Label'>
<b:includable id='main'>
<b:if cond='data:title'>
<h2><data:title/></h2>
</b:if>
<div expr:class='&quot;widget-content &quot; + data: display + &quot;-label-widget-content&quot;'>
<canvas height='300' id='myCanvas' width='300'>
<b:if cond='data: display == &quot;list&quot;'>
<ul>
<b: loop values='data: labels' var='label'>
<li>
. . . . . . . . .
Scroll kebawah temukan kembali kode </b:includable> Masukan tag penutup canvas berikut </canvas>
. . .  . . .  . . .
<b:if cond='data:showFreqNumbers'>
<span class='label-count' dir='ltr'>(<data: label.count/> )</span>
</b:if>
</span>
</b: loop>
</b:if>
</canvas>
<b:include name='quickedit'/>
</div>
</b:includable>
Langkah² diatas sudah dilakukan maka saatnya memasukan script pemanggil. Letakinnya ya tepat dibawah kalian menyimpan script jquery.tagcanvas.js

jQuery Script Plugin

<script type='text/javascript'>
//<![CDATA[
$(document).ready(function() {
$('#myCanvas').tagcanvas({
textColour : '#000',
outlineColour : '#555',

Untuk option script bisa dilihat pada web sumber :D Good luck :)
