另辟蹊径实现轮播图的方法:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <!-- jquery网络引用地址 --> <script src="https://code.jquery.com/jquery-3.1.1.min.js"></script> <title> 两个定时器实现轮播图</title> </head> <body> <img id="app" src="./images/1.jpg" /> <br /> <button id="clear">停止轮播</button> <button id="continue">继续轮播</button> <button id="pre">上一张</button> <button id="next">下一张</button> <script> //要遍历的图片路径数组 var images = [‘./images/1.jpg‘, ‘./images/2.jpg‘, ‘./images/3.jpg‘]; //获取图片对象 var image = document.getElementById("app"); //下标 var index = 0; //定时器 var interval, timeOut = 0; $(function () { // 绑定清除两个定时器的方法 $("#clear").click(function () { console.log(‘清除定时器‘); window.clearInterval(interval); window.clearTimeout(timeOut); }); // 对两个定时器进行重新赋值 $("#continue").click(function () { console.log(‘继续执行定时器‘); interval = setInterval(function () { timeOut = setTimeout(() => { if (index > (images.length - 1)) { index = 0; } image.src = images[index]; index++; }, 1000); }, 1500); }); // 根据下标切换图片 $("#next").click(function () { console.log(‘下一张‘) index++; if (index > (images.length - 1)) { index = 0; } image.src = images[index]; }); // 根据下标切换图片 $("#pre").click(function () { console.log(‘上一张‘) index--; if (index < 0) { index = images.length - 1; } image.src = images[index]; }); // 默认执行主体 interval = setInterval(function () { timeOut = setTimeout(() => { if (index > (images.length - 1)) { index = 0; } image.src = images[index]; index++; }, 1000); }, 1500); }); </script> </body> </html>
