Bootstrap show.bs.modal 事件
Bootstrap 中的 show.bs.modal 事件将在模态即将显示时触发。
此处使用同一个事件设置警报,当模型准备就绪时,该事件会触发。这将导致向访问者显示警报。
我还设置了一个按钮,该按钮通过单击来打开模态,如下面的代码片段所示 −
$(document).ready(function(){ $("#button1").click(function(){ $("#newModal").modal("show"); }); $("#newModal").on('show.bs.modal', function () { alert('The modal will be displayed now!'); }); });
下面是一个示例,演示在 Bootstrap 中实现 show.bs.modal 事件 −
