JS使定时器全部失效

Function.prototype.temp_constructor= Function.prototype.constructor;
Function.prototype.constructor=function(){
    if (arguments && typeof arguments[0]==="string"){
        if (arguments[0]==="debugger")
        return ""
    }
    return Function.prototype.temp_constructor.apply(this, arguments);
};

// hook 定时器函数 替换debugger
_setInterval = setInterval
setInterval = function setInterval(code, time){
    console.log(code, time)
    code = code.toString().replace(/debugger/, "").replace(/function ()/, "function xxx")
    return _setInterval(new Function(code) , time)
}
_setTimeout = setTimeout
setTimeout = function setTimeout(code, time){
    console.log(code, time)
    code = code.toString().replace(/debugger/, "").replace(/function ()/, "function xxx")
    return _setTimeout(new Function(code), time)
}
