禁用开发者模式 -方案整理

本文对开发者模式禁用提供了五种处理方案
禁用右键、定时器增加debugger、监视DOM修改、监听可视高度修改、禁用F12

禁用右键 （防止右键查看源代码、作用不大）

document.oncontextmenu = function () { return false; };

定时器增加debugger

setInterval(function () {
    function doCheck(a) {
        if (("" + a / a)["length"] !== 1 || a % 20 === 0) {
            (function () { } ["constructor"]("debugger")())
        } else {
            (function () { } ["constructor"]("debugger")())
        }
        doCheck(++a)
    }
    try {
        doCheck(0)
    } catch (err) { }
}, 1000);

监视DOM修改

window.addEventListener("DOMCharacterDataModified", () => window.location.reload(), true);
window.addEventListener("DOMAttributeNameChanged", () => window.location.reload(), true);
window.addEventListener("DOMCharacterDataModified", () => window.location.reload(), true);
window.addEventListener("DOMElementNameChanged", () => window.location.reload(),true);
window.addEventListener("DOMNodeInserted", () => window.location.reload(), true);
window.addEventListener("DOMNodeInsertedIntoDocument", () => location.reload(),true);
window.addEventListener("DOMNodeRemoved", () => window.location.reload(), true);
window.addEventListener("DOMNodeRemovedFromDocument", () => location.reload(),true);
window.addEventListener("DOMSubtreeModified", () => window.location.reload(), true);

判断可视高度和可视宽度是否有改变，如有改变则刷新页面

var h = window.innerHeight, w = window.innerWidth;
window.onresize = function () {
    if (h != window.innerHeight || w != window.innerWidth) {
        window.location = "https://www.s.51.com";
    }
};

禁用F12

document.onkeydown=function(){
    if(window.event&&window.event.keyCode==123){
        event.keyCode=0;
        event.returnValue=false;
    }
}
