本文实例为大家分享了js实现缓动动画的具体代码,供大家参考,具体内容如下
利用定时器来控制元素的offsetLeft的值,offsetLeft = 开始位置 + (最终位置 - 开始位置)* 缓动系数
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> * { margin: 0; padding: 0; border: none; list-style: none; } body { background-color: pink; } #nav { width: 900px; height: 63px; background: url("images/doubleOne.png") no-repeat right center #fff; margin: 0 auto; margin-top: 50px; border-radius: 5px; position: relative; } #nav ul { line-height: 70px; } #nav ul li { float: left; height: 63px; width: 88px; text-align: center; cursor: pointer; position: relative; } #t_mail { width: 88px; height: 63px; background: url("images/tMall.png") no-repeat; position: absolute; } </style> </head> <body> <nav id="nav"> <span id="t_mail"></span> <ul> <li>双11狂欢</li> <li>服装会场</li> <li>数码家电</li> <li>母婴童装</li> <li>手机会场</li> <li>美妆会场</li> <li>家居建材</li> <li>进口会场</li> <li>飞猪旅行</li> </ul> </nav> <script> window.onload = function () { var nav = $('nav'); var t_mall = nav.children[0]; var ul = nav.children[1]; var allLis = ul.children; var beginX = 0; for (var i = 0; i < allLis.length; i++) { var li = allLis[i]; li.onmouseover = function () { end = this.offsetLeft; } li.onmousedown = function () { beginX = this.offsetLeft; } li.onmouseout = function () { end = beginX; } } var begin = 0, end = 0; setInterval(function () { begin = begin + (end - begin) / 10; t_mall.style.left = begin + 'px'; }, 10) function $(id) { return typeof id ? document.getElementById(id) : null; } } </script> </body> </html>
