<!DOCTYPE html> <html lang=en> <head> <meta charset=UTF-8> <meta http-equiv=X-UA-Compatible content=IE=edge> <meta name=viewport content=width=device-width, initial-scale=1.0> <title>Document</title> </head> <style> .adver{ width: 300px; height: 200px; border: 1px solid #ccc; background-color: pink; position: absolute; top: 100px; right: 0; } span{ width: 40px; height: 25px; position: absolute; top: 0; right: 0; background-color: #ccc; color: #fff; text-align: center; } </style> <body> <div class=adver> <span>关闭</span> </div> </body> <script> // 获取操作对象 var adver = document.querySelector('.adver'); //延迟消失 // setTimeout(function(){ // // 让div消失 // //display:none opacity:0 right:-300px // adver.style.display = 'none' // },3000) var span = document.querySelector('span'); // 给操作对象添加事件 span.onclick = function(){ // 当点击关闭按钮让整个盒子隐藏 adver.style.display = 'none' // 设置延时定时器 setTimeout(function(){ adver.style.display = 'block' },3000) } </script> </html> 效果图：点击关闭即可隐藏 - 3秒过后既又重新出现
