javascript下拉菜单：如何链接到不同的网站？

Question

我是一名大学生，试图为我的教授创建一个下拉菜单。由于我没有任何编程背景，我找到了一个名为 "SoThink DHTML" 的程序为我生成了一个代码，但其中有一些错误我不知道如何修复。

总体而言，菜单应包含“主页”、“研究”选项卡（3 个子选项卡：“研究项目”、“系统和方法”以及“图像和电影”）、“出版物”、“实验室成员”、“链接”、 ”和“联系我们。”但是，自动生成的代码不提供其中一些标题的链接，我想知道如何手动插入链接？

如何插入路径，以便它们不引用特定文件，但当我移动包含网站的文件夹时更灵活？

我希望这有意义..

非常感谢您提前提供的帮助！

看起来您正在使用相对网址，它根据当前位置查找文件。因此，当包含 url 的文件位于不同位置时，它们的含义不同。

../../public/img/logo.gif

绝对网址从网站的根目录开始，这意味着您可以将包含它们的文件移动到任何位置，但它仍然引用相同的位置。

http://www.somedomain.com/en/public/img/logo.gif
