基于JavaScript实现屏幕滚动效果
屏幕滚动效果:
<html> <head lang="en"> <meta charset="UTF-8"> <title></title> <style> ul,ol { list-style-type: none; } * {margin:0;padding:0;} html,body { width: 100%; height: 100%; } #ul { width: 100%; height: 100%; } ul li{ width: 100%; height: 100%; } #ol { position: fixed; top:0; left:50px; } #ol li { width: 50px; height: 50px; border: 1px solid #000; } </style> <script src="my.js" type="text/javascript"></script> <script> window.onload = function() { var ulBox = $("ul"); var ulBoxLi = ulBox.children; var olBox = $("ol"); var olBoxLi = olBox.children; var bgColor = ["pink","purple","orange","blue","green"]; var leader = 0,target = 0,timer = null; for(var i= 0; i<ulBoxLi.length; i++) { ulBoxLi[i].style.backgroundColor = bgColor[i]; olBoxLi[i].style.backgroundColor = bgColor[i]; olBoxLi[i].index = i; // 记录当前的索引号 olBoxLi[i].onclick = function() { clearInterval(timer); target = ulBoxLi[this.index].offsetTop; // 核心语句 timer = setInterval(function() { leader = leader + (target - leader ) /10; window.scrollTo(0,leader); // 屏幕滑动 //pic.style.left = leader + 'px'; },30) } } } </script> </head> <body> <ul id="ul"> <li>首页</li> <li>关注</li> <li>动态</li> <li>风格</li> <li>作品</li> </ul> <ol id="ol"> <li>首页</li> <li>关注</li> <li>动态</li> <li>风格</li> <li>作品</li> </ol> </body> </html>
