Membuat Slider Carousel Otomatis Berdasarkan Label

Membuat Slider Carousel Otomatis Berdasarkan Label

 

Tutorial kali ini saya akan membahas bagaimana membuat slider Carousel otomatis berdasarkan label. Prinsip kerja dari slider ini sama seperti pada slider otomatis berdasarkan kategori. Anda tinggal mengganti dengan label anda dan slider ini akan bekerja sesuai dengan label yang anda masukkan. Slider Carousel yang saya buat kali ini sangat sederhana dan hanya menggunakan jCarousellite script tanpa menambahkan efek easing dan mousewheel.

1 Setelah semua langkah diatas anda lakukan, letakkan kode berikut ini diatas kode ]]></b:skin>

#carousel{width:auto;height:180px;margin-bottom:0px;position:relative;display:block} #carousel .container{position:absolute;left:39px;width:895px;height:180px;overflow:hidden;background:url(#) repeat center} #carousel #previous_button{position:absolute;width:35px;height:180px;background:url(http://3.bp.blogspot.com/-APGScJbAlLM/T5LDZ9LDgkI/AAAAAAAAAr4/vGy7EquPGME/s1600/prev.png) center;z-index:100;cursor:pointer;border-right:1px solid #ccc} #carousel #previous_button:hover{background:url(http://3.bp.blogspot.com/-4wNqeM6eRvY/T5LGCrdA9iI/AAAAAAAAAsE/4rjwULz47WU/s1600/prev.png) center} #carousel #next_button{position:absolute;right:0;width:40px;height:180px;background:url(http://1.bp.blogspot.com/-pSHFy8ff1R0/T5LDZHkHIzI/AAAAAAAAArw/PCfZ762nK3E/s1600/next.png) center;z-index:100;cursor:pointer;border-left:1px solid #ccc} #carousel #next_button:hover{background:url(http://2.bp.blogspot.com/-vSaPjyDhEMI/T5LGB-g1_lI/AAAAAAAAAsA/wyUPBLWY15E/s1600/next.png) center} #carousel ul{width:100000px;position:relative;margin-top:10px} #carousel ul li{background:#fff url(http://3.bp.blogspot.com/-NsKF7TyEX7I/T418sIGTo7I/AAAAAAAAAnc/OdQmhV73piY/s1600/main.png) repeat-x top;display:inline;float:left;text-align:center;font-weight:700;font-size:.9em;line-height:1.2em;border:1px solid #ccc;width:100px;height:150px;margin:0 4px 20px 3px;padding:6px;-webkit-border-radius:4px;-moz-border-radius:4px;border-radius:4px;} #carousel ul li:hover{filter:alpha(opacity=75);opacity:.75;} #carousel ul li a.slider_title{color:#222;display:block;margin-top:5px} #carousel ul li a.slider_title:hover{color:#cd1713} #carousel a img{display:block;background:#fff;margin-top:0}

2 selanjutnya masih pada posisi Edit HTML, masukkan kode berikut ini diatas kode </head> :

<script type='text/javascript'>
//<![CDATA[
imgr = new Array();
imgr[0] = "http://2.bp.blogspot.com/-uitX7ROPtTU/Tyv-G4NA_uI/AAAAAAAAFBY/NcWLPVnYEnU/s1600/no+image.jpg";
showRandomImg = true;

aBold = true;

summaryPost = 1400;
summaryTitle = 25;
numposts1 = 12;

function removeHtmlTag(strx,chop){
var s = strx.split("<");
for(var i=0;i<s.length;i++){
if(s[i].indexOf(">")!=-1){
s[i] = s[i].substring(s[i].indexOf(">")+1,s[i].length);
}
}

s = s.join("");
s = s.substring(0,chop-1);
return s;
}
function showrecentposts(json) {
j = (showRandomImg) ? Math.floor((imgr.length+1)*Math.random()) : 0;

}

if ("content" in entry) {
var postcontent = entry.content.$t;}

//cmtext = (text != 'no') ? '<i><font color="'+acolor+'">('+pcm+' '+text+')</font></i>' : '';

3 selanjutnya masih pada posisi Edit HTML, masukkan kode berikut ini diatas kode </head> :

<script src='https://rawgit.com/danikece/adanitutorialcid/master/slider-jquery-tutorialcid.min.js' type='text/javascript'/>
<script src='https://rawgit.com/danikece/adanitutorialcid/master/menu-slider-tutorialcid.js' type='text/javascript'/>

4 Langkah selanjutnya adalah memanggil slider tersebut agar muncul di blog kita. Cari kode <div id='main-wrapper'>, kemudian letakkan kode berikut ini diatasnya :

<div id='carousel'>
<div id='previous_button'/>
<div class='container'>
<script>
document.write(&quot;&lt;script src=\&quot;/feeds/posts/default?max-results=&quot;+numposts1+&quot;&amp;orderby=published&amp;alt=json-in-script&amp;callback=showrecentposts\&quot;&gt;&lt;\/script&gt;&quot;);
</script>
<div class='clear'/>
</div>
<div id='next_button'/>
</div>
<script type='text/javascript'>
(function($) {     $(document).ready(function(){
$(&quot;#carousel .container&quot;).jCarouselLite({
    auto:4000,
    scroll: 1,
    speed: 800,
    visible: 4,
    start: 0,
    circular: true,
    btnPrev: &quot;#previous_button&quot;,
    btnNext: &quot;#next_button&quot;
    });
    })})(jQuery)
</script>
