代码如下:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <style type = "text/css"> *{margin: 0; padding: 0;} li { list-style: none; } .box { width: 800px; height: 450px; margin: 50px auto; overflow: hidden; position: relative; } .box span { width: 40px; height: 60px; display: block; position: absolute; top: 225px; margin-top: -20px; cursor: pointer; z-index: 1; } .box #left { background: url('http://cdn.attach.qdfuns.com/notes/pics/201701/14/042311cbd7gbjd7sggkd2b.png') no-repeat; left: 0; display: none; } .box #right { background: url('http://cdn.attach.qdfuns.com/notes/pics/201701/14/042241w8z4hx4m4pjhyjzs.png') no-repeat; right: 0; display: none; } #ad { width: 4000px; height: 450px; position: absolute; } #ad li { float: left; } </style> <script type = "text/javascript"> window.onload = function(){ var ad = document.getElementById("ad"); var lef = document.getElementById("left"); var rig = document.getElementById("right"); var timer = null; //管理定时器 var aspect = true; function animate(obj,speed){ //关闭上一个定时器 clearInterval(obj.timer); //管理定时器 obj.timer = setInterval(autoAd,30); function autoAd(){ //判断左走或者右走 if(speed > 0){ aspect = true; if(obj.offsetLeft >= 0){ obj.style.left = -3200 + 'px'; } }else { aspect = false; if(obj.offsetLeft <= -3200){ obj.style.left = 0; } } //匀速动画: 盒子当前的位置 + 步长 obj.style.left = obj.offsetLeft + speed +"px"; } } animate(ad,-5); //鼠标划入显示控制按钮并关闭 ad.parentNode.onmouseover = function(){ clearInterval(ad.timer); lef.style.display = "block"; rig.style.display = "block"; }; //鼠标离开隐藏控制按钮并启动定时器 ad.parentNode.onmouseout = function(){ clearInterval(ad.timer); clearInterval(timer); lef.style.display = "none"; rig.style.display = "none"; if(aspect){ animate(ad,5); }else{ animate(ad,-5); } }; ad.onclick = function(event){ //关闭自动轮播定时器 clearInterval(ad.timer); clearInterval(timer); var event = event || window.event; if(event.target){ var target = - parseInt(event.target.alt) * 800; }else{ var target = - parseInt(event.srcElement.alt) * 800; } timer = setInterval(function(){ var step = (target - ad.offsetLeft) / 10; step = step > 0 "px"; if(ad.offsetLeft%800 == 0){ clearInterval(timer); } },20) } //右移动 lef.onclick = function(){ clearInterval(timer); animate(ad,5); }; //左移动 rig.onclick = function(){ clearInterval(timer); animate(ad,-5); }; } </script> </head> <body> <div class="box"> <ul id="ad"> <li><img src="/UploadFiles/2021-04-02/042153lscsitwp7sszb6zs.jpg">以上就是本文的全部内容,希望本文的内容对大家的学习或者工作能带来一定的帮助,同时也希望多多支持!
