还是先贴代码吧
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title></title> <script src="js/jquery.js"></script> </head> <style> body{font-family: "微软雅黑";width: 980px; margin: 0 auto; text-align: center;} .box{ width: 300px; height: 300px; background: green; border: 1px solid #e6e6e6; margintop: 50px; line-height: 200px; position: absolute; } button{ border: none; background: green; width: 100px; height: 50px; line-height: 50px; color: #fff; font-size: 16px; margin-top: 50px; } </style> <body> <button>点击开始动画</button> <div class="box" ></div> <script> $(document).ready(function(){ $("button").click(function(){ var div=$(".box"); div.animate({height:'200px',opacity:'0.4'},"slow"); div.animate({width:'200px',opacity:'0.8'},"slow"); div.animate({height:'100px',opacity:'0.4'},"slow"); div.animate({width:'100px',opacity:'0.8'},"slow"); div.animate({right:'100px',opacity:'0.8'},"slow"); div.animate({bottom:'100px',opacity:'0.8'},"slow"); div.animate({left:'100px',opacity:'0.8'},"slow"); div.animate({top:'100px',opacity:'0.8'},"slow",function(){ alert("The paragraph is over"); }); }); }); </script> <script> $(document).ready(function(){ $("button").click(function(){ var div=$(".box"); div.animate({height:'300px',opacity:'0.4'},"slow"); div.animate({width:'300px',opacity:'0.8'},"slow"); div.animate({height:'100px',opacity:'0.4'},"slow"); div.animate({width:'100px',opacity:'0.8'},"slow",function(){ alert("The paragraph is over"); }); }); }); }); </script> </body> </html>
所谓的回调函数,其实就是在 speed 或 duration 参数可以设置许多不同的值,比如 "slow", "fast", "normal" 或毫秒 后面再添加函数,显示相对应的内容,以提示网民
