HTML网站禁用右键F12代码 屏蔽审查元素 防止修改页面代码 <script type='text/javascript'> const handler = setInterval(function () { console.clear(); const before = new Date(); debugger; const after = new Date(); const cost = after.getTime() - before.getTime(); if (cost > 100) { } }, 1); //屏蔽右键菜单 document.oncontextmenu = function (event) { if (window.event) { event = window.event; } try { var the = event.srcElement; if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")) { return false; } return true; } catch (e) { return false; } } //屏蔽粘贴 document.onpaste = function (event) { if (window.event) { event = window.event; } try { var the = event.srcElement; if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")) { return false; } return true; } catch (e) { return false; } } //屏蔽复制 //屏蔽剪切 document.oncut = function (event) { if (window.event) { event = window.event; } try { var the = event.srcElement; if (!((the.tagName == "INPUT" && the.type.toLowerCase() == "text") || the.tagName == "TEXTAREA")) { return false; } return true; } catch (e) { return false; } } //禁止f12 function fuckyou() { window.open("/", "_blank"); //新窗口打开页面 window.close(); //关闭当前窗口(防抽) window.location = "about:blank"; //将当前窗口跳转置空白页 } //禁止Ctrl+U var arr = [123, 17, 18]; document.oncontextmenu = new Function("event.returnValue=false;"), //禁用右键 window.onkeydown = function (e) { var keyCode = e.keyCode || e.which || e.charCode; var ctrlKey = e.ctrlKey || e.metaKey; console.log(keyCode + "--" + keyCode); if (ctrlKey && keyCode == 85) { e.preventDefault(); } if (arr.indexOf(keyCode) > -1) { e.preventDefault(); } } function ck() { console.profile(); console.profileEnd(); //我们判断一下profiles里面有没有东西，如果有，肯定有人按F12了，没错！！ if (console.clear) { console.clear() }; if (typeof console.profiles == "object") { return console.profiles.length > 0; } } function hehe() { if ((window.console && (console.firebug || console.table && /firebug/i.test(console.table()))) || ( typeof opera == 'object' && typeof opera.postError == 'function' && console.profile.length > 0)) { fuckyou(); } if (typeof console.profiles == "object" && console.profiles.length > 0) { fuckyou(); } } hehe(); window.onresize = function () { if ((window.outerHeight - window.innerHeight) > 100) //判断当前窗口内页高度和窗口高度，如果差值大于100，那么呵呵 fuckyou(); } document.onkeydown = function (event) { if ((event.keyCode == 112) || //屏蔽 F1 (event.keyCode == 113) || //屏蔽 F2 (event.keyCode == 114) || //屏蔽 F3 (event.keyCode == 115) || //屏蔽 F4 // (event.keyCode == 116) || //屏蔽 F5 (event.keyCode == 117) || //屏蔽 F6 (event.keyCode == 118) || //屏蔽 F7 (event.keyCode == 119) || //屏蔽 F8 (event.keyCode == 120) || //屏蔽 F9 (event.keyCode == 121) || //屏蔽 F10 (event.keyCode == 122) || //屏蔽 F11 (event.keyCode == 123)) //屏蔽 F12 { return false; } } window.onhelp = function () { return false; } </script>
教你如何让网站整体变成灰色代码 css样式加载head里面：<style type="text/css"> html{ filter: grayscale(100%); -webkit-filter: grayscale(100%); /* webkit */ -moz-filter: grayscale(100%); /*firefox*/ -ms-filter: grayscale(100%); /*ie9*/ -o-filter: grayscale(100%); /*opera*/ filter: url("data:image/svg+xml;utf8,#grayscale"); filter:progid:DXImageTransform.Microsoft.BasicImage(grayscale=1); -webkit-filter: grayscale(1); } </style>操作最简单的：<html lang="zh-CN" xml:lang="zh-CN" style="filter: grayscale(100%);">JS定时:<script> function isDateBetween(start, end) { var startDate = new Date(start) var endDate = new Date(end) var current = new Date() return current >= startDate && current < endDate } (function() { var inGrayRange = isDateBetween('2022-05-11 00:00:00', '2022-05-12 00:00:00'); //var inGrayRange = true var grayCss = document.getElementById('J-gary-bg'); var ieGuessULile = document.getElementsByClassName('J-ie-guess-u-like'); window.inGrayRange = inGrayRange; if (!inGrayRange && grayCss) { grayCss.remove(); } if (inGrayRange && ieGuessULile && ieGuessULile.length) { for (var i = 0; i< ieGuessULile.length; i++) { ieGuessULile[i].style.display = "none"; } } })() </script>PS：以上几种方法，喜欢哪种就自己挖去吧！
