優化版（分隔線以上直接實現3D標簽雲效果展示）：
一、在博客園管理-設置-頁首Html代碼中加入：
<script type="text/javascript" src="http://files.cnblogs.com/Zjmainstay/swfobject.js"></script>
<script type="text/javascript" src="http://demo.zjmainstay.cn/cnblogs/getTags.php?url=http%3A%2F%2Fwww.cnblogs.com%2FZjmainstay%2Ftag%2F"></script>
<script type="text/javascript" src="http://files.cnblogs.com/Zjmainstay/Zjmainstay_cnblogs_tags.js"></script>
注1：請修改第一個script的src的url=部分，修改成你自己的博客園域名，為http://www.cnblogs.com/Zjmainstay/tag/的urlencode結果。第二個script不變。
注2：http://demo.zjmainstay.cn/cnblogs/getTags.php?hl可獲取getTags.php源碼，也是下面的get_cnblogs_tags.php的源碼。
二、設置-頁腳Html代碼中加入：
<div id="ZjmainstayCnblogsSWFTags"></div>
三、設置-通過CSS定制頁面風格 加入：
#ZjmainstayCnblogsSWFTags{
overflow: visible;
position: absolute;
right: 10px;
top: 735px;
width: 160px;
z-index: 10000;
}

昨天晚上在一個其他站點的博客上看到了一個標簽雲動畫，挺喜歡的，動手把它移植到了博客園上了，嘿嘿~
定制標簽雲主要涉及2個外部引用的js文件：swfobject.js 和 Zjmainstay_cnblogs_tags.js，和一個動畫文件：tagcloud.swf，還有一個后台解析博客園標簽生成標簽雲動畫參數var tag的get_cnblogs_tags.php文件。swfobject.js 、tagcloud.swf是給Zjmainstay_cnblogs_tags.js調用來創建標簽雲動畫用的。下面是Zjmainstay_cnblogs_tags.js的源碼：
注：tags內容太長，這里提取出來：

因為我調用的ajax響應服務器是一個免費php空間的，運行速度好慢，常常解析超時，因此被我屏蔽了。我采用了自己為var tag賦值的方式，而它的值是通過本地使用get_cnblogs_tags.php（ajax請求文件）獲取博客園標簽頁解析並生成的，用戶引用此部分ajax時，可自行修改$.ajax的url即可。get_cnblogs_tags.php源碼如下：
View Code
<?php header("Content-type: text/html; charset=utf-8"); $url = $_GET['url']; if(empty($url)) $url = 'http://www.cnblogs.com/Zjmainstay/tag/'; $divData = getWebDiv('id="taglist"',$url); $pattern = '/<a(?:.*?)href="((?:http(?:s?):\/\/)?(?:[^\"\/]+)(?:[^\"]*))"(?:[^>]*?)>([^<]*?)<\/a>/i'; preg_match_all($pattern, $divData, $links); $urls = $links[1]; $tags = $links[2]; $output = ''; foreach($urls as $i => $url){ $output .= urlencode("<a href='{$url}' class='tag-link-118' title='1 個話題' style='font-size: 8pt;'>{$tags[$i]}</a>"); } if(!empty($output)) echo urlencode('<tags>').$output.urlencode('</tags>'); else echo 'false'; exit(0); function getWebDiv($div_id,$url=false,$data=false){ if($url !== false){ $data = file_get_contents( $url ); } $charset_pos = stripos($data,'charset'); if($charset_pos) { if(stripos($data,'utf-8',$charset_pos)) { $data = iconv('utf-8','utf-8',$data); }else if(stripos($data,'gb2312',$charset_pos)) { $data = iconv('gb2312','utf-8',$data); }else if(stripos($data,'gbk',$charset_pos)) { $data = iconv('gbk','utf-8',$data); } } preg_match_all('/<div/i',$data,$pre_matches,PREG_OFFSET_CAPTURE); //獲取所有div前綴 preg_match_all('/<\/div/i',$data,$suf_matches,PREG_OFFSET_CAPTURE); //獲取所有div后綴 $hit = strpos($data,$div_id); if($hit == -1) return false; //未命中 $divs = array(); //合並所有div foreach($pre_matches[0] as $index=>$pre_div){ $divs[(int)$pre_div[1]] = 'p'; $divs[(int)$suf_matches[0][$index][1]] = 's'; } //對div進行排序 $sort = array_keys($divs); asort($sort); $count = count($pre_matches[0]); foreach($pre_matches[0] as $index=>$pre_div){ //<div $hit <div+1 時div被命中 if(($pre_matches[0][$index][1] < $hit) && ($hit < $pre_matches[0][$index+1][1])){ $deeper = 0; //彈出被命中div前的div while(array_shift($sort) != $pre_matches[0][$index][1] && ($count--)) continue; //對剩余div進行匹配，若下一個為前綴，則向下一層，$deeper加1， //否則后退一層，$deeper減1，$deeper為0則命中匹配，計算div長度 foreach($sort as $key){ if($divs[$key] == 'p') $deeper++; else if($deeper == 0) { $length = $key-$pre_matches[0][$index][1]; break; }else { $deeper--; } } $hitDivString = substr($data,$pre_matches[0][$index][1],$length).'</div>'; break; } } return $hitDivString; }
Zjmainstay_cnblogs_tags.js中調用的SWFObject是從swfobject.js來的，而其參數SWFObject("http://files.cnblogs.com/Zjmainstay/tagcloud.swf", "tagcloudflash", "200", "200", "9", "#282828");中的tagcloud.swf，便是對tagcloud.swf文件的調用。
至此，源碼部分已經介紹完了。接下來是博客園對它的引用。
博客園將其引用進來，主要是在博客園管理-設置-頁首Html代碼中加入：
<script type="text/javascript" src="http://files.cnblogs.com/Zjmainstay/swfobject.js"></script> <script type="text/javascript" src="http://files.cnblogs.com/Zjmainstay/Zjmainstay_cnblogs_tags.js"></script>
並在設置-頁腳Html代碼中加入：
<div id="ZjmainstayCnblogsSWFTags"></div>
即可。這里的id="ZjmainstayCnblogsSWFTags" 對應Zjmainstay_cnblogs_tags.js中的write("ZjmainstayCnblogsSWFTags")。此時的<div id="ZjmainstayCnblogsSWFTags"></div>會顯示在頁腳，
為了讓它顯示在“我的標簽”下面，在 設置-通過CSS定制頁面風格 加入：
#ZjmainstayCnblogsSWFTags{ position: absolute; left: 762px; top: 1186px; z-index:10000; }
將其絕對定位至我的標簽下面即可。
（完）
********************** 分隔 ******************
這里會發現一個問題：拖動頁面右側導航條的時候會發現動畫浮動，好像卡機的感覺，求解決。
********************** 補充 ******************
獨立標簽雲用例，請在下面運行此段代碼后面填入“6”后點擊運行，查看運行效果。
