例子:滑动效果
一、滑动效果
<head> <style type="text/css"> *{ margin:0px auto; padding:0px} #wai{ width:100%; height:500px;} #left{height:500px; background-color:#63C; float:left} #right{ height:500px; background-color:#FC3; float:left} #anniu{ width:50px; height:50px; background-color:#06F; position:absolute; top:225px; z-index:10; } #anniu:hover{ cursor:pointer} </style> </head> <body> <div id="wai"> <div id="left" style="width:200px"></div> <div id="right" style="width:800px"></div> </div> <div id="anniu" style="left:175px" onclick="hua()"></div> <script type="text/javascript"> var id; function hua() { id = window.setInterval("dong()",10); } //滑动的方法,调一次滑动3px function dong() { //改蓝色的宽度 200px var zuo = document.getElementById("left"); kd = zuo.style.width; if(parseInt(kd.substr(0,kd.length-2))>=800) { window.clearInterval(id); return; } kd = parseInt(kd.substr(0,kd.length-2))+3; zuo.style.width = kd+"px"; //改黄色的宽度 var you = document.getElementById("right"); ykd = you.style.width; ykd = parseInt(ykd.substr(0,ykd.length-2))-3; you.style.width = ykd+"px"; //改小块的left var hong = document.getElementById("anniu"); hleft = hong.style.left; hleft = parseInt(hleft.substr(0,hleft.length-2))+3; hong.style.left = hleft+"px"; } </script> </body>
效果图:点击按钮方块,就会向右走
二、滑轮固定
<body> <div style="width:100%; height:100px; background-color:#63F"></div> <div id="menu" style="width:100%; height:50px; background-color:#F36;"></div> <input type="button" value="http://www.mamicode.com/滚动" onclick="gun()" /> <div style="width:100%; height:1000px; background-color:#FF6"></div> </body> <script type="text/javascript"> window.onscroll = function(){ var d = document.getElementById("menu"); if(window.scrollY >= 100) { d.style.position = "fixed"; d.style.top = "0px"; } else { d.style.position = "relative"; } } function gun() { window.scrollTo(0,100); } </script>
