Question

我正在为客户工作。我写了一些javascript，为客户打印一个链接列表，但它不像它应该的那样工作。您可以找到文件here。它应该打印三列，但它只打印前两列。在我改变一些变量名之前，这曾经工作过。什么可能出错？请参阅grizfirestarters.com/stores_dyn.htm

上的完成页面

编辑：我通过设置列大小而不是动态来解决问题。有点好玩，但完成工作。代码如下：

在我更改一些变量名之前，这曾经工作过。什么可能出错？

只是猜测，你填补了更改变量名称 - 更改它们，然后重新开始，或者再次触摸它们，取决于你的感受 - 看代码，它看起来比2008版权更旧约会，我建议将代码踢到现代的尖叫和

或者，在您喜欢的任何浏览器中查看开发人员控制台，并看到第45行有一个未定义的变量，即#include <cassert> template<class A, class B> bool f() { return true; } int main() { assert(f<char, int>()); }

更改变量名后JS脚本无法正常工作
