[筆記] Blogger標籤雲

網頁預設的標籤通常都是一長串，所以只要標籤越來越多，整個網頁就被拉得很長，因此用標籤雲可以有效的縮短整體標籤長度，同時因為字體大小有所區隔，也不至於擠成一團!

1. 在]]></b:skin>之前輸入
   
   /** Label Cloud Styles */
#labelCloud
#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}
   
2. 在]]></b:skin>之後、</head>之前加入下面的Java Script
   <script type='text/javascript'>
// Label Cloud User Variables
var lcBlogURL = 'http://life-minded.blogspot.com';
var cloudMin = 1;
var maxFontSize = 20;
var maxColor = [0,0,255];
var minFontSize = 10;
var minColor = [0,0,0];
var lcShowCount = false;B
</script>
   其中在var lcBlogURL = 'http://life-minded.blogspot.com';中將http://life-minded.blogspot.com取代為自已blog的網址，maxFontSize和maxColor則分別為標籤最大字型及最大字型的顏色，而minFontSize和var minColor則分別為標籤最小字型及最小字型的顏色，字型大小以px為單位，顏色則是使用RGB色碼。
   
   
3. 在你的template中搜尋這一段，將
   <b:widget id='Label1' locked='false' title='Labels' type='Label'/>
   以下列程式取代
   <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 -----------------
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 ta=0
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])
}
}
tz = labelCount.length-1;
lc2 = document.getElementById('labelCloud');
ul = document.createElement('ul');
ul.className = 'label-cloud';
for(var t in ts){
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 = lcBlogURL+'/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>
