JS实现仿QQ聊天窗口抖动特效
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>JavaScript层抖动效果</title> <style type="text/css"> #body{text-align:center;} #test{width:200px;position:absolute;margin:10px auto;height:100px;border:2px dotted red;text-align:center} </style> </head> <body> <div> <div> <input type="button" value="~点这里让我抖抖吧~" /></div> <div> <input type="button" value="晃晕了，我不抖了！" /></div> <div id="test"> <br> <img border="0" src="smiley.gif"></div> </div> <p></p> <p></p> </body> </html> <script type="text/javascript"> var m=document.getElementById("test"); function SKclass (obj,Rate,speed) { var oL=obj.offsetLeft; var oT=obj.offsetTop; this.stop=null; this.oTime=null; var om=this; this.start=function(){ if(parseInt(obj.style.left)==oL-2){ obj.style.top=oT+2+"px"; setTimeout(function(){obj.style.left=oL+2+"px"},Rate) } else{ obj.style.top=oT-2+"px"; setTimeout(function(){obj.style.left=oL-2+"px"},Rate) } this.oTime=setTimeout(function(){om.start()},speed); } this.stop=function(){ clearTimeout(this.oTime); } } var nn=new SKclass(m,20,70); </script> </body> </html>
再来一个更简单的
<img id="win" src="http://www.jb51.netUploadPic/2008-9/2008962512241.jpg"> <br /><br /> <button>振动</button> <script > function zd(u){ var a=['top','left'],b=0; u=setInterval(function(){ document.getElementById('win').style[a[b%2]]=(b++)%4<2?0:4; if(b>15){clearInterval(u);b=0} },32) } </script>
