hide.bs.modal引导事件
当模态即将被隐藏时，Bootstrap中的hide.bs.modal事件就会触发。
以下按钮隐藏模式-
<button type="button" class="btn btn-default btn-lg" id="button1"> Click to hide </button>
在单击“隐藏”按钮之后，将触发hide.bs.modal事件，并且在隐藏模式之前。这是hide.bs.modal事件的脚本：
$("#newModal").on('hide.bs.modal', function () {
alert('The modal is about to be hidden.');
});以下是在Bootstrap中实现hide.bs.modal事件的完整示例-
