效果图：
1.JS代码，加入网站头部head文件，就是全站屏蔽
创建一个JS文件，添加下面代码
var a=document.body.innerHTML;
document.body.innerHTML=a.replace(/\ufeff/g,'');
var system = {
win: false,
mac: false,
xll: false
};
var p = navigator.platform;
var us = navigator.userAgent.toLowerCase();
system.win = p.indexOf("Win") == 0;
system.mac = p.indexOf("Mac") == 0;
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
if (system.win || system.mac || system.xll) {
var iframe_url='/close.html';
$("head").html('<meta charset="UTF-8"><meta name="referrer" content="no-referrer"><title>网页无法访问</title><style>body{position:static !important;}body *{ visibility:hidden; }</style> ');
$("body").empty();
$(document).ready(function () {
$("body").html('<iframe style="width:100%; height:100%;position:absolute;margin-left:0px;margin-top:0px;top:0%;left:0%;" id="mainFrame" src="'+iframe_url+'" frameborder="0" scrolling="no"></iframe>').show();
$("body *").css("visibility", "visible");
});
}
document.oncontextmenu = function(e) {
var e = e || window.event;
e.returnValue = false;
return false;
}
window.onkeydown = function(e) {
if (e.ctrlKey && e.keyCode == 83) {
alert('禁止使用ctrl+s');
e.preventDefault();
e.returnValue = false;
return false;
}
}
'jQuery';
2.自己网站根目录添加/close.html文件。
代码如下：
<html><head>
<meta charset="UTF-8">
<title>网站维护中...</title>
<meta name="viewport" content="initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no">
<style>
*{margin:0;padding:0}body,html{width:100%;height:100%;overflow:hidden;font-family:Helvetica,Arial,Microsoft Yahei,sans-serif;background-image:url(back.jpg);background-color:#354141;background-repeat:repeat;background-size:cover;font-size:14px;position:fixed;text-shadow:1px 1px rgba(0,0,0,.3)}h2{color:#fff;font-size:28px;font-weight:400;text-transform:capitalize;margin:0 0 30px}li{display:inline-block;font-size:42px;font-weight:400;text-align:center;height:100px;text-shadow:none;vertical-align:middle;color:#fff;margin:10px 0;height:auto;padding-bottom:15px;background:0 0;width:136px;border-right:2px dashed rgba(255,255,255,.26)}li:last-child{border:none}li span{line-height:70px}li div{display:block;font-size:16px;margin-top:0;text-align:center;background:rgba(255,255,255,.06);color:#fff;padding:0;height:45px;line-height:45px}.fed-main-info{width:90%;min-width:320px;position:absolute;top:50%;left:50%;color:#fff;font-size:16px;text-align:center;transform:translate(-50%,-50%);z-index:999;padding-bottom:80px}.fed-foot-info{position:fixed;text-align:center;width:100%;bottom:40px;color:#eee}@media(max-width:768px){.fed-main-info{width:320px}li:nth-last-child(3){border:none}.fed-foot-info{bottom:20px}}
</style>
</head>
<body>
<script type="text/javascript"> document.body.oncontextmenu=document.body.ondragstart= document.body.onselectstart=document.body.onbeforecopy=function(){return false;};
document.body.onselect=document.body.oncopy=document.body.onmouseup=function(){document.selection.empty();}; </script>
<script type="text/javascript">
document.onkeydown=function(){
var e = window.event||arguments[0];
if(e.keyCode==123){
return false;
}
if((e.ctrlKey)&&(e.shiftKey)&&(e.keyCode==73)){
return false;
}
if((e.ctrlKey)&&(e.keyCode==85)){
return false;
}
if((e.ctrlKey)&&(e.keyCode==83)){
return false;
}
}
document.oncontextmenu=function(){
return false;
}
var threshold = 160;
window.setInterval(function() {
if (window.outerWidth - window.innerWidth > threshold ||
window.outerHeight - window.innerHeight > threshold) {
function disableDebugger() {
debugger;
}
$(document).ready(function () {
disableDebugger();
});
}
}, 1e3);
</script>
