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 style=\"color:#FF0000\">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。
