Bootstrap 模态框即将隐藏时的事件
bootstrapweb developmentcss framework更新于 2024/2/5 16:44:17
Bootstrap 中的 hide.bs.modal 事件在模态框即将隐藏时触发。
首先，点击按钮 − 时隐藏 Bootstrap 模态框
$("#button1").click(function(){
$("#newModal").modal("hide");
});
现在，使用 hide.bs.modal 类，并在点击按钮 − 时生成模态框即将隐藏的警报
$("#newModal").on(&39;hide.bs.modal&39;, function () {
alert(&39;模态框即将隐藏隐藏。');
});
让我们看一个示例，说明 hide.bs.modal 事件的用法 −
