人这种卑鄙的东西，什么都会习惯的。——陀思妥耶夫斯基《罪与罚》
今天遇到一个问题，我想阻止浏览器默认的滚动事件，却阻止不了还一直报错
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <div style="height: 2000px;background:#888"> </div> <script> document.addEventListener('wheel', e => { e.preventDefault() }) </script> </body> </html>
此处在addEventListener中添加一个参数``{ passive: false }
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <div style="height: 2000px;background:#888"> </div> <script> document.addEventListener('wheel', e => { e.preventDefault() }, { passive: false }) </script> </body> </html>
即可解决
