引导模态淡入淡出发生，但不弹出答案

【问题标题】：Bootstrap modal fade happening, but not pop up引导模态淡入淡出发生，但不弹出
【发布时间】：2016-01-12 04:02:48
【问题描述】：

我正在尝试编写一个在提交登录凭据时弹出的模式（最终我想使用 ajax 来验证 ldap 服务器并根据组成员身份弹出一个模式，但还没有）。

当我在浏览器中打开它并单击按钮时，容器会像应有的那样变暗，但没有出现实际的模态 div。

【问题讨论】：

你打错了modal-dialog，你错过了破折号。如果你更正了，它应该可以工作
:facepalm。谢谢你。

【解决方案1】：

您必须将role="document" 添加到<div class="modal-dialog" >

应该是这样的

<div class="modal-dialog modal-lg" role="document">
