Question

我一直在收到错误消息：＆＃34; RangeError：超出最大调用堆栈大小＆＃34;当使用nodejs包＆＃34; zombie＆＃34;和jQuery。我已经尽可能地提炼了代码以重新创建错误。

这是一个文件zombie.js，可以使用命令＆＃34; node zombie.js＆＃34;运行nodejs：

var Browser = require("zombie");
browser = new Browser();
browser.visit("http://localhost:8000/background.html", function(error) {
    console.log("error: " + error);
});

这里是background.html：

<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript">
  var source = "<html><body>Hello, world!</body></html>";
  source = $(source);
</script>

错误发生在以下行：

source = $(source);

可能导致这种情况的原因是什么？我该如何解决？

编辑：正如P.scheit建议的那样，我尝试在启用调试的情况下运行，并使用几行输出来显示程序中的位置。这是输出：

Zombie: Opened window http://localhost:8000/background.html 
Zombie: GET http://localhost:8000/background.html => 200
Zombie: Loaded document http://localhost:8000/background.html
Zombie: GET http://localhost:8000/jquery.min.js => 200
Before the line: var source = "<html><body>Hello, world!</body></html>";
After the line: var source = "<html><body>Hello, world!</body></html>";
Before the line: source = $(source);
Maximum call stack size exceeded undefined
error: RangeError: Maximum call stack size exceeded
Zombie: Event loop is empty

我使用--trace选项运行节点，看起来这是反复发生的事情，直到调用堆栈的大小太大：

正如您所看到的，这是一个循环，在调用堆栈中以更深的方式结束。这会重复数千次，直到调用堆栈大小太大。

使用jQuery解析html时，zombie.js调用堆栈大小超出
