+# 知识点：js生成cookie，js事件断点
+
+## 解题思路
+
+模拟请求地址，发现返回的是一串js
+
+![请求](./img/1.png)
+
+既然返回是js，那么直接事件断点
+
+![请求](./img/2.png)
+
+断点调试下一步，下一步，下一步，直到`https://www.python-spider.com/challenge/11`停下来
+
+![请求](./img/3.png)
+
+这里的会发现如下这段代码
+
+    try {
+        eval(y.replace(/\b\w+\b/g, function(y) {
+            return x[f(y, z) - 1] || ("_" + y)
+        }));
+        break
+    } catch (
+
+把`eval`替换成`a = `,并在底部打印`a`函数
+
+    try {
+        a = (y.replace(/\b\w+\b/g, function(y) {
+            return x[f(y, z) - 1] || ("_" + y)
