当模态窗口即将显示时的引导程序事件
当模态窗口即将显示时,Bootstrap 中的 show.bs.modal 事件被触发。在此,我添加了一个生成警报的脚本 −
<script> $(document).ready(function(){ $("#button1").click(function(){ $("#newModal").modal("show"); }); $("#newModal").on('show.bs.modal', function () { alert('The modal will be displayed now!'); }); }); </script>
在点击按钮时,上述示例代码会生成模态窗口。之后,我使用了 show.bs.modal 事件,以便在模态窗口即将变得可见时生成警报。
以下示例演示了当模态窗口即将显示时,如何在 Bootstrap 中触发 show.bs.modal 事件 −
