如何在 Twitter Bootstrap 中使用模态关闭事件?

原文:https://www . geeksforgeeks . org/如何使用-模式-关闭-事件-在 twitter-bootstrap/

Bootstrap Modals 提供了一个轻量级的、多用途的 JavaScript 弹出窗口,它是可定制和响应的。它们可用于在网站中显示提醒弹出窗口、视频和图像。引导模式分为三个主要部分:页眉、正文和页脚。

语法:

class | tabindex | role | aria-labelledby

方式:显示弹出菜单,有表头、表体、表尾,有关闭提交按钮。

<div class="modal fade" 
     id="exampleModal" 
     tabindex="-1" 
     role="dialog" 
     aria-labelledby="exampleModalLabel" 
     aria-hidden="true">
    <div class="modal-dialog" role="document">
    </div>
</div>

说明:下面是一个静态模态示例(表示其位置和显示已被覆盖),包括模态头、模态体(填充所需)和模态尾(可选)。我们要求您尽可能将模态头包含在消除动作中,或者提供另一个显式消除动作。
