本文实例讲述了基于jQuery实现的旋转彩圈。分享给大家供大家参考。具体实现方法如下：
<!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>旋转的圈</p> <div id="div1"></div> </body> </html>
运行效果图如下：
希望本文所述对大家的jQuery程序设计有所帮助。
