奇数页和偶数页上可点击的章节

遵循 Gonzalo Medina 提出的伟大思想每页右侧有可点击的章节，我想将其扩展到双面书。我做错了什么？似乎此代码并不关心页面是偶数还是奇数...

以下是代码：

背景包文档提供了一个示例（示例 4），说明当奇数页和偶数页需要不同的背景时如何进行；基本上，您需要在最后\AddEverypageHook使用钩子和。\BgMaterial

这是您的代码的简化版本（您的\scriptext和\striptextout命令产生了错误，因此我抑制了它们）：

在发货时页码是已知的，因此没有必要，\checkoddpage...并且简单\ifodd测试是完全安全的。
