【问题描述】:
当显示引导模式时,可以使用诸如
之类的代码轻松检索相关数据$('#myModal').on('show.bs.modal', function (e) {
var id = $(e.relatedTarget).data('id');
alert(id);
}
关闭 bootstrap modal时是否可以这样?
特别是当被特定按钮(即确认按钮,而不是任何一个取消按钮)关闭时? relatedTarget 似乎无法从模式内的任何 buttons 或 hidden.bs.modal 事件中获得。
在以下操场中,data-id 属性值应显示在删除按钮下方,当以类似方式单击 modal 的“是”时,data-id 将显示模态体:
$(document).ready(function () {
$('#deleteModal').on('show.bs.modal', function (e) {
$('#testOutput,#testOutput2').text('');
var id = $(e.relatedTarget).data('id');
$('#deleteId').text(id || 'id retrieval failed');
});
$('#deleteModal').on('hidden.bs.modal', function (e) {
var id = $(e.relatedTarget).data('id'); //does not work
$('#testOutput2').text(id || '"hidden.bs.modal" id retrieval failed');
});
$('#confirmDeleteBtn').click(function (e) {
var id = $(e.relatedTarget).data('id'); //does not work
//var id = $(this).closest('.modal').data('id'); //doesnt work neither
$('#testOutput').text(id || '"btn.close .modal" id retrieval failed');
});
});

请注意打开button的id不是恒定的,即有很多删除buttons能够打开单个对话框。

@freedomn-m 必须承认可能会被视为模棱两可,但是从 html 元素获取属性值将是微不足道的,所以我相信大多数人(如果不是所有人)都会理解将其理解为 indetended。无论如何,你能建议一个明确的标题吗?

@freedomn-m 啊,这里的主要困惑是关于 Bootstrap 的modal data-passing pattern。因此,我希望“传递数据->打开->关闭->获取数据”而不是“传递数据->打开->获取数据”,但不确定如何将其包含在标题中。无论如何它都与关闭按钮无关(好吧,除了关闭时,我需要之前传递的数据)。
