Label Clouds

常常我們會很羨慕Yahoo時尚的Label Clouds
但是如今我們自己的blog也能做到

使用此套件前,請先增加"標籤"原件
強烈建議使用前請先存檔備份
以及做以下動作時,不用展開小裝置範本

Step1.在"]]>"之前加入CSS樣式表

/* Label Cloud Styles
----------------------------------------------- */
#labelCloud {text-align:center;font-family:arial,sans-serif;}
#labelCloud .label-cloud li{display:inline;background-image:none !important;padding:0 5px;margin:0;vertical-align:baseline !important;border:0 !important;}
#labelCloud ul{list-style-type:none;margin:0 auto;padding:0;}
#labelCloud a img{border:0;display:inline;margin:0 0 0 3px;padding:0}
#labelCloud a{text-decoration:none}
#labelCloud a:hover{text-decoration:underline}
#labelCloud li a{}
#labelCloud .label-cloud {}
#labelCloud .label-count {padding-left:0.2em;font-size:9px;color:#000}
#labelCloud .label-cloud li:before{content:"" !important}

在</head>之前，加入程式碼

<script type='text/javascript'>
// Label Cloud User Variables
var cloudMin = 1;
var maxFontSize = 20;
var maxColor = [0,0,255];
var minFontSize = 10;
var minColor = [0,0,0];
var lcShowCount = false;
</script>

最後請確定已經新增Blogger官方的元件"標籤"，之後再收尋下面字樣。（不用展開小裝置範本）

<b:widget id='Label1'
locked='false' title='標籤' type='Label'/>

把下面的程式碼取代成上面的程式碼

<b:widget id='Label1' locked='false' title='Label Cloud' type='Label'>
<b:includable id='main'>
 
<b:if cond='data:title'>
   
<h2><data:title/></h2>
 
</b:if>

 
<div class='widget-content'>
 
<div id='labelCloud'/>
<script type='text/javascript'>

// Don't change anything past this point -----------------
// Cloud function s() ripped from del.icio.us
function s(a,b,i,x){
     
if(a &gt;b){
         
var m=(a-b)/Math.log(x),v=a-Math.floor(Math.log(i)*m)
            
}
     
else{
         
var m=(b-a)/Math.log(x),v=Math.floor(Math.log(i)*m+a)
         
}
     
return v
  
}


var c=[];
var labelCount = new Array();  
var ts = new Object;
<b:loop values='data:labels' var='label'>
var theName = &quot;<data:label.name/>&quot;;
ts[theName] = <data:label.count/>;
</b:loop>

for (t in ts){
    
if (!labelCount[ts[t]]){
          
labelCount[ts[t]] = new Array(ts[t])
          
}
       
}
var ta=cloudMin-1;
tz = labelCount.length - cloudMin;
lc2 = document.getElementById('labelCloud');
ul = document.createElement('ul');
ul.className = 'label-cloud';
for(var t in ts){
   
if(ts[t] &lt; cloudMin){
      
continue;
      
}
   
for (var i=0;3 &gt; i;i++) {
            
c[i]=s(minColor[i],maxColor[i],ts[t]-ta,tz)
             
}      
        
var fs = s(minFontSize,maxFontSize,ts[t]-ta,tz);
        
li = document.createElement('li');
        
li.style.fontSize = fs+'px';
        
li.style.lineHeight = '1';
        
a = document.createElement('a');
        
a.title = ts[t]+' Posts in '+t;
        
a.style.color = 'rgb('+c[0]+','+c[1]+','+c[2]+')';
        
a.href = '/search/label/'+encodeURIComponent(t);
        
if (lcShowCount){
            
span = document.createElement('span');
            
span.innerHTML = '('+ts[t]+') ';
            
span.className = 'label-count';
            
a.appendChild(document.createTextNode(t));
            
li.appendChild(a);
            
li.appendChild(span);
            
}
         
else {
            
a.appendChild(document.createTextNode(t));
            
li.appendChild(a);
            
}
        
ul.appendChild(li);
        
abnk = document.createTextNode(' ');
        
ul.appendChild(abnk);
   
}
 
lc2.appendChild(ul);    
</script>

<noscript>
   
<ul>
   
<b:loop values='data:labels' var='label'>
     
<li>
       
<b:if cond='data:blog.url == data:label.url'>

如果要換顏色可以參考顏色代碼
