Dedecms实现tags云标签随机颜色与字体大小方法总结

function getTagStyle()
{
$minFontSize=8; //最小,可根据需要自行更改
$maxFontSize=18; //最大字体大小,可根据需要自行更改
return 'font-size:'.($minFontSize+lcg_value()*(abs($maxFontSize-$minFontSize))).'px;color:#'.dechex(rand(0,255)).dechex(rand(0,196)).dechex(rand(0,255));
} 

{dede:tag row='45' getall='1' sort='hot'}
<a href='[field:link/]' title="[field:tag /]([field:total /])" style="[field:total runphp=yes]@me=getTagStyle();[/field:total]">[field:tag /]</a>
{/dede:tag} 

<script src="/ajax/libs//1.4.2/jquery.min.js" type="text/"></script>
   <script type="text/javascript">
      $(document).ready(function() {
         var tags_a = $("#tags a");
         tags_a.each(function(){
             var x = 9;
             var y = 0;
             var rand = parseInt(Math.random() * (x - y + 1) + y);
             $(this).addClass("tags"+rand);
          });
      })  
   </script>

css代码如下：
<style>
body,a{ font-size:13px;}
a{ color:#333333; text-decoration:none;}
.taglist{ width:250px;overflow:hidden;border:#dddddd solid 1px;}
.taglist .tit{ width:100%; height:24px; line-height:24px; background-color:#565662;}
.taglist .tit a{ padding-left:8px; color:#ffffff;}
#tags a{height:26px; line-height:26px;padding-right:6px;}
#tags .tags0{}
#tags .tags1{color:#C00; font-size:24px;}
#tags .tags2{color:#030; font-size:16px;}
#tags .tags3{color:#00F;}
#tags .tags4{ font-size:16px;}
#tags .tags5{color:#C00; font-size:20px;}
#tags .tags6{color:#F06 font-size:20px;}
#tags .tags7{color:#030; font-weight:bold; font-size:18px;}
#tags .tags8{color:#F06; font-weight:bold;}
#tags .tags9{color:#C00; font-weight:bold;font-size:16px;}
#tags a:hover{ color:#F00; text-decoration:underline;}
.w95{ width:95%; margin:0 auto; padding-top:6px; padding-bottom:6px;}
.taglist .w95{}
</style>

html结构：
<div class="taglist">
<div class="tit"><a href="#">TAG标签</a></div>
<div class="w95" id="tags">
这里面放你的A标题就可以了。
</div>

<script language="javascript" type="text/javascript">
function randomKeys(){
var alinks = document.getElementById("keywords").getElementsByTagName("a");
var aColors = new Array("#990033", "#006666", "#9966CC","#FFCC66", "#6633CC", "#9999CC","#999966", "#996666", "#9933CC","#FF99CC");
var aSize = new Array("11px", "12px", "13px","14px", "15px", "16px","17px");
