本文實例講述了基於jQuery實現的旋轉彩圈。分享給大家供大家參考。具體實作方法如下：
<!DOCTYPE html>
<html>
<head>
<script src="jquery-1.7.1.min.js"></script>
<script>
for(var i=0;i<100000;i++)
{
if(i%4==0)
setTimeout("$('#div1').css({'border-left':'40px solid red','border-bottom':'40px solid green','border-right':'40px solid yellow','border-top':'40px solid blue'})",2000*i);
if(i%4==1)
setTimeout("$('#div1').css({'border-left':'40px solid blue','border-bottom':'40px solid red','border-right':'40px solid green','border-top':'40px solid yellow'})",2000*i);
if(i%4==2)
setTimeout("$('#div1').css({'border-left':'40px solid yellow','border-bottom':'40px solid blue','border-right':'40px solid red','border-top':'40px solid green'})",2000*i);
if(i%4==3)
setTimeout("$('#div1').css({'border-left':'40px solid green','border-bottom':'40px solid yellow','border-right':'40px solid blue','border-top':'40px solid red'})",2000*i);
}
</script>
<style>
#div2{
width: 100px;
height: 100px;
border-left: 40px solid red;
border-right: 40px solid yellow;
border-bottom: 40px solid green;
border-top:40px solid blue;
background-color:#FFFFFF;
border-radius:900px/900px;
display:none;
top:0px;
left:0px;
position:relative;
z-index:1;
}
#div1{
width: 100px;
height: 100px;
border-left: 40px solid red;
border-right: 40px solid yellow;
border-bottom: 40px solid green;
border-top:40px solid blue;
background-color:#FFFFFF;
border-radius:90px/90px;
}
</style>
</head>
<body>
<p style="color:#FF0000">旋转的圈</p>
<div id="div1"></div>
</body>
</html>
運作效果圖如下：
希望本文所述對大家的jQuery程式設計有所幫助。
