标签云代码

因为接下来会为了我自己的需要修改得越来越奇怪，所以还是存一下比较保险= =

这个应该是特殊符号不会出现乱码的版本，详情看这里。

在它前面加上

/* 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}

在它后面加上

<script type='text/javascript'>
// Label Cloud User Variables
var cloudMin = 1;
var maxFontSize = 20;
var maxColor = [255,0,255];
var minFontSize = 15;
var minColor = [64,128,128];
var lcShowCount = true;
</script>

在不钩选扩展窗口小部件模板的情况下，找到类似

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

的代码，替换为

<b:widget id='Label1' locked='false' title='标签云' 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&#39;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;
var na = new Object;

<b:loop values='data:labels' var='label'>
var theName = &quot;<data:label.url/>&quot;;

</b:loop>

for (t in ts){
na[t] = decodeURIComponent(t.split(&#39;/&#39;).pop());

labelCount[ts[t]] = new Array(ts[t])
}

lc2 = document.getElementById(&#39;labelCloud&#39;);
ul = document.createElement(&#39;ul&#39;);
ul.className = &#39;label-cloud&#39;;
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);

a.title = na[t]+&#39; 共有 &#39;+ts[t]+&#39; 篇日志&#39;;

a.appendChild(document.createTextNode(na[t]));
li.appendChild(a);
li.appendChild(span);
}
else {
a.appendChild(document.createTextNode(na[t]));
li.appendChild(a);
}
ul.appendChild(li);
abnk = document.createTextNode(&#39; &#39;);
ul.appendChild(abnk);
}
lc2.appendChild(ul);
