即将显示模态时的Bootstrap事件

当将要显示模态时,会引发Bootstrap中的show.bs.modal事件。在这里,我添加了一个脚本来生成警报-

<script>
$(document).ready(function(){
  $("#button1").click(function(){
    $("#newModal").modal("show");
  });
  $("#newModal").on('show.bs.modal', function () {
    alert('The modal will be displayed now!');
  });
});
</script>

在上方,单击按钮即可生成模态。之后,我使用show.bs.modal事件在模态即将可见时生成警报。

以下是一个示例,演示如何在将要显示模式时在Bootstrap中触发show.bs.modal事件-
