Twitter引导模式禁用其他链接

Question

我面临一个难以用语言解释的问题，但我会尽力而为 问题：在我的rails应用程序的标题中添加modal会禁用其他链接，这些链接位于其旁边，直到访问modal。

示例：|Home| Mail |Settings(Modal Link)| 以上示例是我的标题看起来如何，上面提到的三个是链接。 在我访问Settings模式之前，Home和Mail链接仍处于禁用状态。但是，一旦我查看Modal，我就可以再次访问Home和Mail。

当我使用Chrome开发者工具（Inspect Element）时，我可以看到Modal隐藏在这两个Home and Mail链接之上。访问Settings(Modal Link)后，这些链接上没有隐藏的Modal，可以访问。

有什么输入吗？
