html - 1页上的Bootstrap 2模态？

Question

我正在尝试在一个页面上制作 2 个模式，一个用于登录表单，另一个用于注册表单。以下是声明

<div class="modal fade" id="signUpModal" tabindex="-1" role="dialog" aria-hidden="true">
<div class="modal fade" id="signInModal" tabindex="-1" role="dialog" aria-hidden="true">

以下是显示模态的链接：

<a class="nav-link" data-toggle="modal" data-target="#signUpModal">Sign Up</a>
<a class="nav-link" data-toggle="modal" data-target="#signInModal">Sign In</a>

当我单击指向#signUpModal 的链接时，它工作正常，但是当我单击指向#signInModal 的链接时，没有任何反应，没有显示模式。如果我然后单击指向#signUpModal 的链接，则#signInModal 然后显示堆叠在#signUpModal 的顶部。

如何让第二个模态正确显示？

使用代码如下：

笔记！

注意你没有设置相同的id两次......id是唯一的，你可以在每个页面中使用它一次（例如：id="exampleModalLabel"所以在第二个模型集中id="exampleModalLabel2"）
