 MEMBINA "WIDGETIZED TABBED BOX" |
| June 28, 2009 Posted by: Fauzie |
Dalam tutorial ini, kita akan cuba belajar membina atau membuat apa yang dipanggil "tabbed content box" di dalam blogger minima template. Kod-kod yang digunakan ialah kod CSS, XHTML dan Javascript. Di bawah ini ialah screenshot "tabbed content box". Widget ini sesuai diletakkan di bahagian sidebar
Script yang digunakan untuk membuat tabber ini telah di download dari link ini dan dicipta oleh Patrick Fitzgerald. Anda boleh download script ini atau copy & paste kod dan script yang tertera di bawah ini. Scriptnya agak panjang dan anda dinasihatkan supaya berhati-hati sewaktu copy dan paste.

Langkah pertama ialah copy kod/script di bawah ini. Klik Layout->klik Edit HTML->klik Expand Widget Template. Cari </head> dan paste atau masukkan kod/script ini di atas </head>.

</script>
Kedudukan script di atas apabila anda paste adalah seperti berikut:
<script type='text/javascript'>
//<![CDATA[
document.write('<style type="text/css">.tabber{display:none;}</style>');
/* paste script/kod tabber di atas di sini */
//]]>
</script>
</head>
Kemudian cari pula kod ini: <div id='sidebar-wrapper'. Di bahagian bawahnya taip atau copy & paste kod-kod berikut.
<div class='tabber'>
<b:section class='tabbertab' id='tab1' maxwidgets='1'/>
<b:section class='tabbertab' id='tab2' maxwidgets='1'/>
<b:section class='tabbertab' id='tab3' maxwidgets='1'/>
</div>
Untuk contoh dalam tutorial ini, kita telah membuat 3 tab. Jika anda inginkan mempunyai lebih dari 3 tab, apa yang anda perlu buat ialah taip atau copy & paste <b:section class...... dan letakkan di bawah section class tab 3 dan tukar id kepada tab 4 seperti berikut.
<div class='tabber'>
<b:section class='tabbertab' id='tab1' maxwidgets='1'/>
<b:section class='tabbertab' id='tab2' maxwidgets='1'/>
<b:section class='tabbertab' id='tab3' maxwidgets='1'/>
<b:section class='tabbertab' id='tab4' maxwidgets='1'/>
</div>
Sekarang kita perlu tambah atau masukkan kod CSS pula. Copy & paste kod seperti di bawah ini di bahagian atas body {
/* start tab styles */
.tabberlive{
margin:0;
padding:5px;
clear:both;
background:$tbbxbgcolor;
border:1px solid $tbbxbrcolor;
}
.tabbernav {
margin:0;
padding: 3px 0;
border-bottom: 1px solid $tbbxbrcolor;
font-family:Arial,Helvetica,sans-serif;
font-size:12px;
font-weight:bold;
}
.tabbernav li {
list-style:none;
margin:0;
display:inline;
}
.tabbernav li a {
padding:3px 0.5em;
margin-right:1px;
border:1px solid $tbbxbrcolor;
border-bottom:none;
background:$tbbxcolor2;
text-decoration:none;
color:$tbbxcolor1;
}
.tabbernav li a:hover {
color:$tbbxcolor2;
background:$tbbxcolor1;
border-color:$tbbxbrcolor;
text-decoration:none;
}
.tabbernav li.tabberactive a,
.tabbernav li.tabberactive a:hover {
background:$tbbxcolor1;
color:$tbbxcolor2;
border-bottom: 1px solid $tbbxcolor1;
}
.tabberlive .tabbertab {
padding:5px;
border:1px solid $tbbxbrcolor;
border-top:0;
background:$tbbxcolor1;
}
.tabberlive .tabbertab h2,
.tabberlive .tabbertabhide {
display:none;
}
.tabbertab .widget-content ul{
list-style:none;
margin:0 0 10px 0;
padding:0;
}
.tabbertab .widget-content li {
border-bottom:1px solid $tbbxbrcolor;
margin:0 5px;
padding:2px 0 5px 0;
}
/* end tab styles */
Di dalam kod ini terdapat 4 "variable" yang diberi nama sebagai tbbxbgcolor, tbbxbrcolor, tbbxcolor1 dan tbbxcolor2. Ini adalah merujuk kepada warna background, warna border dan warna kotak tab. Anda boleh menukar kod-kod in kepada kod warna hexadecimal untuk mendapatkan warna yang anda suka.
Langkah terakhir ialah memasukkan pula atau menambah kod-kod "definition" seperti di bawah ini. Tempat untuk paste kod-kod ini ialah di bahagian bawah
/* Varible definitions
==============
<Variable name="tbbxbgcolor" description="Tab box Background Color" type="color" default="#f8f8f8" value="#f8f8f8">
<Variable name="tbbxbrcolor" description="Tab box Border Color" type="color" default="#dcdcdc" value="#dcdcdc">
<Variable name="tbbxcolor1" description="Tab box Color 1" type="color" default="#ffffff" value="#ffffff">
<Variable name="tbbxcolor2" description="Tab box Color 2" type="color" default="#5588aa" value="#5588aa">
