JavaScript检查是否按下F12,并自动跳转到指定地址.

主要是为了防止某一些人查看网站的请求.当然这就是防小白的而已.有点知识的就算了.

效果图:
进入网站并按下 F12:

先按下 F12 在进入网站:

代码：

!function(e) {
function n(e) {
function n() {
return u
}

function o() {
window.Firebug && window.Firebug.chrome && window.Firebug.chrome.isInitialized ? t("on") : (a = "off", console.log(d), console.clear(), t(a))
}

function t(e) {
u !== e && (u = e, "function" == typeof c.onchange && c.onchange(e))
}

function r() {
l || (l = !0, window.removeEventListener("resize", o), clearInterval(f))
}
"function" == typeof e && (e = {
onchange: e
});
var i = (e = e || {}).delay || 500,
c = {};
c.onchange = e.onchange;
var a, d = new Image;
d.__defineGetter__("id", function() {
a = "on"
});
var u = "unknown";
c.getStatus = n;
var f = setInterval(o, i);
window.addEventListener("resize", o);
var l;
return c.free = r, c
}
var o = o || {};
o.create = n, "function" == typeof define ? (define.amd || define.cmd) && define(function() {
return o
}) : "undefined" != typeof module && module.exports ? module.exports = o : window.jdetects = o
}(), jdetects.create(function(e) {
var a = 0;
var n = setInterval(function() {
if ("on" == e) {
setTimeout(function() {
if (a == 0) {
a = 1;
//此处改成你要跳转的地址
top.location.href = 'https://www.csdn.com'
}
}, 200)
}
}, 100)
});
