分享一段检测开发者工具的代码，有点意思

偶然在一个网站看到的，打开开发者工具会自动在 debugger 那行中断执行，这思路不错

var check = (function () {
    var callbacks = [], timeLimit = 50, open = false;
    setInterval(loop, 1);
    return {
        addListener: function (fn) {
            callbacks.push(fn);
        },
        cancleListenr: function (fn) {
            callbacks = callbacks.filter(function (v) {
                return v !== fn;
            });
        }
    }
    function loop() {
        var startTime = new Date();
        debugger;
        if (new Date() - startTime > timeLimit) {
            if (!open) {
                callbacks.forEach(function (fn) {
                    fn.call(null);
                });
            }
            open = true;
	    window.stop();
            alert('没事别老研究人家接口了，好好做站去吧');
        } else {
            open = false;
        }
    }
})();

check.addListener(function () {
	window.location.reload();
});
