Bootstrap 3 个嵌套模式 – 背景 z-index 和点击关闭模式

Bootstrap 3 nested modals – backdrop z-index and close modal on click

我正在开发一个 Web 应用程序 (Asp.Net MVC 5),用户必须在其中创建许多数据记录并映射到其他记录。用户必须能够创建到现有或新创建记录的映射。

一个典型的例子是创建一个地址:

selection 是使用 bootstrap 模态实现的。 按下 select 按钮(例如 select 城市)会显示一个包含 table 的模式,显示 table 中所有 select 可用的记录。 table 的模态包含一个添加新按钮以添加新实体,这会打开另一个模态。

为了能够重用视图,我将代码拆分为部分视图,如下所示:

…等等

我有两个问题:

我尝试在模态显示中设置背景的 z-index,以确保它们隐藏其他模态,但这没有用 => 背景显示在当前模态之上。

这是显示问题的 fiddle:jsFiffle

SO 不允许我 link 在不向问题添加代码的情况下使用 JSFiddle,所以这里是代码:

问题是模式覆盖了孔屏。由于模态框的边缘,背景是可见的,但不可点击,因为它完全被模态框覆盖了。 从模态中删除边距并将其添加到模态对话框中解决了问题。
