一.js hook 过无限debugger

var _constructor = constructor;
Function.prototype.constructor = function(s) {
    if (s == "debugger") {
        console.log(s);
        return null;
    }
    return _constructor(s);
}

//去除无限debugger
Function.prototype.__constructor_back = Function.prototype.constructor ;
Function.prototype.constructor = function() {
    if(arguments && typeof arguments[0]==='string'){
        //alert("new function: "+ arguments[0]);
        if( "debugger" === arguments[0]){
            // arguments[0]="consoLe.Log(\"anti debugger\");";
            //arguments[0]=";";
            return
    }
    }
    return Function.prototype.__constructor_back.apply(this,arguments);
};

var _Function = Function;
Function = function(s) {
    if (s == "debugger") {
        console.log(s);
        return null;
    }
    return _Function(s);
}

二.过debugger—1 constructor 构造器构造出来的

var _constructor = constructor;
Function.prototype.constructor = function(s) {
    if (s == "debugger") {
        console.log(s);
        return null;
    }
    return _constructor(s);
}

三.过debugger—2 eval的

(function() {
    'use strict';
    var eval_ = window.eval;
    window.eval = function(x) {
        eval_(x.replace("debugger;", "  ; "));
    }
    ;
    window.eval.toString = eval_.toString;
}
)();

四.过debugger 阿布牛逼

function Closure(injectFunction) {
    return function() {
        if (!arguments.length)
            return injectFunction.apply(this, arguments)
        arguments[arguments.length - 1] = arguments[arguments.length - 1].replace(/debugger/g, "");
        return injectFunction.apply(this, arguments)
    }
}

var oldFunctionConstructor = window.Function.prototype.constructor;
window.Function.prototype.constructor = Closure(oldFunctionConstructor)
//fix native function
window.Function.prototype.constructor.toString = oldFunctionConstructor.toString.bind(oldFunctionConstructor);

var oldFunction = Function;
window.Function = Closure(oldFunction)
//fix native function
window.Function.toString = oldFunction.toString.bind(oldFunction);

var oldEval = eval;
window.eval = Closure(oldEval)
//fix native function
window.eval.toString = oldEval.toString.bind(oldEval);

// hook GeneratorFunction
var oldGeneratorFunctionConstructor = Object.getPrototypeOf(function*() {}).constructor
var newGeneratorFunctionConstructor = Closure(oldGeneratorFunctionConstructor)
newGeneratorFunctionConstructor.toString = oldGeneratorFunctionConstructor.toString.bind(oldGeneratorFunctionConstructor);
Object.defineProperty(oldGeneratorFunctionConstructor.prototype, "constructor", {
    value: newGeneratorFunctionConstructor,
    writable: false,
    configurable: true
})

// hook Async Function
var oldAsyncFunctionConstructor = Object.getPrototypeOf(async function() {}).constructor
var newAsyncFunctionConstructor = Closure(oldAsyncFunctionConstructor)
newAsyncFunctionConstructor.toString = oldAsyncFunctionConstructor.toString.bind(oldAsyncFunctionConstructor);
Object.defineProperty(oldAsyncFunctionConstructor.prototype, "constructor", {
    value: newAsyncFunctionConstructor,
    writable: false,
    configurable: true
})

// hook dom
var oldSetAttribute = window.Element.prototype.setAttribute;
window.Element.prototype.setAttribute = function(name, value) {
    if (typeof value == "string")
        value = value.replace(/debugger/g, "")
    // 向上调用
    oldSetAttribute.call(this, name, value)
}
;
var oldContentWindow = Object.getOwnPropertyDescriptor(HTMLIFrameElement.prototype, "contentWindow").get
Object.defineProperty(window.HTMLIFrameElement.prototype, "contentWindow", {
    get() {
        var newV = oldContentWindow.call(this)
        if (!newV.inject) {
            newV.inject = true;
            core.call(newV, globalConfig, newV);
        }
        return newV
    }
})
