Bootstrap show.bs.modal 事件
bootstrapweb developmentcss framework
Bootstrap 中的 show.bs.modal 事件在模态框即将显示时触发。
此处使用相同的事件设置警报，当模型准备好显示时，该事件触发。这会导致向访问者显示警报。
此外，我还设置了一个按钮，点击该按钮即可打开模态框，如以下代码片段所示 −
$(document).ready(function(){
$("#button1").click(function(){
$("#newModal").modal("show");
});
$("#newModal").on('show.bs.modal', function () {
alert('The modal will be displayed now!');
});
});
