为什么我的两个模态中只有一个显示？答案

【问题标题】：Why is only one of my two modals showing?为什么我的两个模态中只有一个显示？
【发布时间】：2019-02-14 09:40:55
【问题描述】：

我在同一页面上有两个模式。其中一个显示得很好。但是，第二个没有显示。只有黑暗的“不透明”屏幕显示，但不显示模态本身。我读过其他帖子，但似乎没有什么对我有用。

【解决方案1】：

如果您将内联 z:index 更改为 10000 或大于 10 的值，您将能够与模态交互。

【讨论】：

这适用于我共享的代码。但是，我的网站有很多 modals，大约 5 个，当我按照你提到的那样更改 z-index 时，它仍然不会显示。
这是无效的代码：codepen.io/paulamourad/pen/mvGJqV?editors=1000

【解决方案2】：

你有一个使用 z-index 的内联样式。只需完全删除 z-index； Bootstrap 为您处理关卡。

【讨论】：

对我的代码不起作用。只有黑屏出现。所有其他模态都有效（我有大约 5 个）。

【解决方案3】：

经过多次尝试，我没有关闭一个</div> 标签。就是这样！
