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">

这里是显示模态的链接：

<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？

与 a 一起使用时使用 href="#idOfModal"，在使用按钮时使用 data-target="#idOfModal"

Answer 2

使用代码如下：

注意！

请注意不要设置相同的id 两次...id 是唯一的，您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id="exampleModalLabel2"）
