来源：互联网发布：英菲克安装软件密码编辑：程序博客网时间：2024/06/05 19:12

经常看到别人的博客里面有动态的云标签页，感觉很是高大上，自己也很像弄一个。于是去找寻源码，在阿里西西页面特效中找到了云标签的源码，经过分析和解剖，弄成了符合博客园的js.

　　首先，找到博客园页面的管理界面，

　　在其中加入以下代码：

<style type="text/css">#div1 {position:relative; width:200px; height:150px; margin: 2px auto 0; }#div1 a {position:absolute; top:0px; left:0px; font-family: Microsoft YaHei; color:#fff; font-weight:bold; text-decoration:none; padding: 1px 2px; }#div1 a:hover {border: 1px solid #eee; background: #000; }#div1 .blue {color:blue;}#div1 .red {color:red;}#div1 .yellow {color:yellow;}#div1 .green {color:green;}</style><script type="text/javascript">var radius = 60;var dtr = Math.PI/180;var d=300;var mcList = [];var active = false;var lasta = 1;var lastb = 1;var distr = true;var tspeed=10;var size=200;var mouseX=0;var mouseY=0;var howElliptical=1;var aA=null;var oDiv=null;window.onload=function (){    var i=0;

代码分析

　　以上源码，就可以直接在你的博客园ID上面显示云标签了

　　那么我们分析以下，上面的代码：

　　这个部分的代码，应该是直接嵌入到body里面的，所以引用的css js都要加入标签，下面是css的代码：

<style type="text/css">#div1 {position:relative; width:200px; height:150px; margin: 2px auto 0; }#div1 a {position:absolute; top:0px; left:0px; font-family: Microsoft YaHei; color:#fff; font-weight:bold; text-decoration:none; padding: 1px 2px; }#div1 a:hover {border: 1px solid #eee; background: #000; }#div1 .blue {color:blue;}#div1 .red {color:red;}#div1 .yellow {color:yellow;}#div1 .green {color:green;}</style>

　　这里面的div是我们下面将要用到的标签内容div的id，通过这个id就可以引用到这里面的样式。

　　上面最重要的一个参数

#div1 {position:relative; width:200px; height:150px; margin: 2px auto 0; }

　　这段代码定义了云标签插件div的宽度和高度，调整适当的像素值，适应你的博客即可。

　　下面是js的代码，radius定义了云标签的半径，可以通过设置该值，调整云标签的旋转半径，也就是球形的大小

<script type="text/javascript">var radius = 60;var dtr = Math.PI/180;var d=300;var mcList = [];var active = false;var lasta = 1;var lastb = 1;var distr = true;var tspeed=10;var size=200;var mouseX=0;var mouseY=0;var howElliptical=1;var aA=null;var oDiv=null;window.onload=function (){    var i=0;    var oTag=null;        oDiv=document.getElementById('div1');        aA=oDiv.getElementsByTagName('a');        for(i=0;i<aA.length;i++)    {        oTag={};                oTag.offsetWidth=aA[i].offsetWidth;        oTag.offsetHeight=aA[i].offsetHeight;                mcList.push(oTag);    }        sineCosine( 0,0,0 );        positionAll();        oDiv.onmouseover=function ()    {        active=true;    };        oDiv.onmouseout=function ()    {        active=false;    };        oDiv.onmousemove=function (ev)    {        var oEvent=window.event || ev;                mouseX=oEvent.clientX-(oDiv.offsetLeft+oDiv.offsetWidth/2);        mouseY=oEvent.clientY-(oDiv.offsetTop+oDiv.offsetHeight/2);                mouseX/=5;        mouseY/=5;    };        setInterval(update, 30);};function update(){    var a;    var b;        if(active)    {        a = (-Math.min( Math.max( -mouseY, -size ), size ) / radius ) * tspeed;        b = (Math.min( Math.max( -mouseX, -size ), size ) / radius ) * tspeed;    }    else    {        a = lasta * 0.98;        b = lastb * 0.98;    }        lasta=a;    lastb=b;        if(Math.abs(a)<=0.01 && Math.abs(b)<=0.01)    {        return;    }        var c=0;    sineCosine(a,b,c);    for(var j=0;j<mcList.length;j++)    {        var rx1=mcList[j].cx;        var ry1=mcList[j].cy*ca+mcList[j].cz*(-sa);        var rz1=mcList[j].cy*sa+mcList[j].cz*ca;                var rx2=rx1*cb+rz1*sb;        var ry2=ry1;        var rz2=rx1*(-sb)+rz1*cb;                var rx3=rx2*cc+ry2*(-sc);        var ry3=rx2*sc+ry2*cc;        var rz3=rz2;                mcList[j].cx=rx3;        mcList[j].cy=ry3;        mcList[j].cz=rz3;                per=d/(d+rz3);                mcList[j].x=(howElliptical*rx3*per)-(howElliptical*2);        mcList[j].y=ry3*per;        mcList[j].scale=per;        mcList[j].alpha=per;                mcList[j].alpha=(mcList[j].alpha-0.6)*(10/6);    }        doPosition();    depthSort();}function depthSort(){    var i=0;    var aTmp=[];        for(i=0;i<aA.length;i++)    {        aTmp.push(aA[i]);    }        aTmp.sort    (        function (vItem1, vItem2)        {            if(vItem1.cz>vItem2.cz)            {                return -1;            }            else if(vItem1.cz<vItem2.cz)            {                return 1;            }            else            {                return 0;            }        }    );        for(i=0;i<aTmp.length;i++)    {        aTmp[i].style.zIndex=i;    }}function positionAll(){    var phi=0;    var theta=0;    var max=mcList.length;    var i=0;        var aTmp=[];    var oFragment=document.createDocumentFragment();        //随机排序    for(i=0;i<aA.length;i++)    {        aTmp.push(aA[i]);    }        aTmp.sort    (        function ()        {            return Math.random()<0.5?1:-1;        }    );        for(i=0;i<aTmp.length;i++)    {        oFragment.appendChild(aTmp[i]);    }        oDiv.appendChild(oFragment);        for( var i=1; i<max+1; i++){        if( distr )        {            phi = Math.acos(-1+(2*i-1)/max);            theta = Math.sqrt(max*Math.PI)*phi;        }        else        {            phi = Math.random()*(Math.PI);            theta = Math.random()*(2*Math.PI);        }        //坐标变换        mcList[i-1].cx = radius * Math.cos(theta)*Math.sin(phi);        mcList[i-1].cy = radius * Math.sin(theta)*Math.sin(phi);        mcList[i-1].cz = radius * Math.cos(phi);                aA[i-1].style.left=mcList[i-1].cx+oDiv.offsetWidth/2-mcList[i-1].offsetWidth/2+'px';        aA[i-1].style.top=mcList[i-1].cy+oDiv.offsetHeight/2-mcList[i-1].offsetHeight/2+'px';    }}function doPosition(){    var l=oDiv.offsetWidth/2;    var t=oDiv.offsetHeight/2;    for(var i=0;i<mcList.length;i++)    {        aA[i].style.left=mcList[i].cx+l-mcList[i].offsetWidth/2+'px';        aA[i].style.top=mcList[i].cy+t-mcList[i].offsetHeight/2+'px';                aA[i].style.fontSize=Math.ceil(12*mcList[i].scale/2)+8+'px';                aA[i].style.filter="alpha(opacity="+100*mcList[i].alpha+")";        aA[i].style.opacity=mcList[i].alpha;    }}function sineCosine( a, b, c){    sa = Math.sin(a * dtr);    ca = Math.cos(a * dtr);    sb = Math.sin(b * dtr);    cb = Math.cos(b * dtr);    sc = Math.sin(c * dtr);    cc = Math.cos(c * dtr);}</script>

　　最后添加自己的云标签内容，即可，后面的class会调用上面css定义的样式，如果没有自己喜欢的颜色或者样式，自己定义就行了。
