jquery标签【无规则标签云样式】

jquery制作一个简单的标签云无规则样式，每次页面刷新展示的标签云样式都不一样。通过随机分配样式类名称，来实现多种标签云样式排列

<script type="text/javascript">
$(document).ready(function(){
    /*随机取颜色*/
    var tags_a = $("#tags").find("a");
    tags_a.each(function(){
        var x = 9;
        var y = 0;
        var rand = parseInt(Math.random() * (x - y + 1) + y);
        $(this).addClass("size"+rand);
    });
});
</script>

<style type="text/css">
*{margin:0;padding:0;list-style-type:none;}
a,img{border:0;}
body{font:12px/180% Arial, Helvetica, sans-serif ,"宋体";}

.demo{background:#FFF8DE;border:solid 1px #ff6600;width:380px;margin:20px auto;}
.demo h2{font-size:18px;height:32px;padding:10px 0 0 20px;font-family:"微软雅黑","宋体";border-bottom:solid 1px #ff6600;}
.taglist{padding:20px 20px 30px 20px;}
