js逆向之无限debugger

过无限debugger通用方法

• eval形式的

eval_ = eval;
eval = function(a){if(!a.indexOf('debugger')){return ''}else{return eval_(a)}}  

• Function形式的

(function() {
	var __Function__ = Function.__Function__ || Function;
	var __Empty__ = Function.__Empty__ || function() {};
	Function = function() {
		for (var i=0; i<arguments.length; i++) {
			if ((typeof arguments[i] == 'string') && arguments[i].indexOf('debugger')>=0) {
				return __Empty__;
			}
		}
		return __Function__.apply(this, Array.prototype.slice.call(arguments, 0));
	}
	Function.__proto__.constructor = Function;
	Function.__Function__ = __Function__;
})();
