Javascript隨機標籤雲代碼執行個體，javascript執行個體
先來看一下效果
代碼如下
<!DOCTYPE HTML><html><head><meta charset="UTF-8"><title>隨機標籤雲</title><style type="text/css">*{ margin:0; padding:0}a{ text-decoration:none}#wrap{ width:400px; margin:auto}</style> <script type="text/javascript"> window.onload=function(){ var obox=document.getElementById("wrap"); var obj=obox.getElementsByTagName("a"); //隨機方法 function rand(num){ return parseInt(Math.random()*num+1); } //隨機顏色值 function randomcolor(){ var str=Math.ceil(Math.random()*16777215).toString(16); if(str.length<6){ str="0"+str; } return str; } //迴圈 for( len=obj.length,i=len;i--;){ obj[i].className="color"+rand(5); obj[i].style.zIndex=rand(5); obj[i].style.fontSize=rand(12)+12+"px"; // obj[i].style.background="#"+randomcolor(); obj[i].style.color="#"+randomcolor(); obj[i].onmouseover=function(){ this.style.background="#"+randomcolor(); } obj[i].onmouseout=function(){ this.style.background="none"; } } } </script></head><body> <div id="wrap"> <a href="#">web標準學習</a> <a href="#">css</a> <a href="#">javascript</a> <a href="#">html5</a> <a href="#">canvas</a> <a href="#">video</a> <a href="#">audio</a> <a href="#">jQuery</a> <a href="#">jQuerymobile</a> <a href="#">flash</a> <a href="#">firefox</a> <a href="#">chrome</a> <a href="#">opera</a> <a href="#">IE9</a> <a href="#">css3.0</a> <a href="#">andriod</a> <a href="#">apple</a> <a href="#">google</a> <a href="#">jobs</a> </div></body></html>
這個的演算法較為簡單（偶能看得懂 orz....），但也基本上實現了要求
