我有一个与数据库行相关联的 HTML 行表。我希望每一行都有一个“删除行”链接,但我想事先与用户确认。
有没有办法使用 Twitter Bootstrap 模态对话框来做到这一点?

对于此任务,您可以使用已经可用的插件和 Bootstrap 扩展。或者您可以仅使用 3 行代码制作您自己的确认弹出窗口。检查一下。
假设我们有这个链接(注意 data-href
而不是 href
)或我们想要删除确认的按钮:
<a href="#" data-href="delete.php?id=23" data-toggle="modal" data-target="#confirm-delete">Delete record #23</a>
<button class="btn btn-default" data-href="/delete.php?id=54" data-toggle="modal" data-target="#confirm-delete">
Delete record #54
</button>
此处 #confirm-delete
指向 HTML 中的模式弹出 div。它应该有一个像这样配置的“确定”按钮:
<div class="modal fade" id="confirm-delete" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
...
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<a class="btn btn-danger btn-ok">Delete</a>
</div>
</div>
</div>
</div>
现在您只需要这个小的 javascript 来使删除操作可确认:
$('#confirm-delete').on('show.bs.modal', function(e) {
$(this).find('.btn-ok').attr('href', $(e.relatedTarget).data('href'));
});
因此在 show.bs.modal
事件删除按钮 href
设置为具有相应记录 id 的 URL。

发布食谱
我意识到在某些情况下可能需要执行 POST 或 DELETE 请求而不是 GET。它仍然很简单,没有太多代码。使用这种方法查看下面的演示:
// Bind click to OK button within popup
$('#confirm-delete').on('click', '.btn-ok', function(e) {
var $modalDiv = $(e.delegateTarget);
var id = $(this).data('recordId');
$modalDiv.addClass('loading');
$.post('/api/record/' + id).then(function() {
$modalDiv.modal('hide').removeClass('loading');
});
});
// Bind to modal opening to set necessary data properties to be used to make request
$('#confirm-delete').on('show.bs.modal', function(e) {
var data = $(e.relatedTarget).data();
$('.title', this).text(data.recordTitle);
$('.btn-ok', this).data('recordId', data.recordId);
});
// Bind click to OK button within popup
$('#confirm-delete').on('click', '.btn-ok', function(e) {
var $modalDiv = $(e.delegateTarget);
var id = $(this).data('recordId');
$modalDiv.addClass('loading');
setTimeout(function() {
$modalDiv.modal('hide').removeClass('loading');
}, 1000);
// In reality would be something like this
// $modalDiv.addClass('loading');
// $.post('/api/record/' + id).then(function() {
// $modalDiv.modal('hide').removeClass('loading');
// });
});
// Bind to modal opening to set necessary data properties to be used to make request
$('#confirm-delete').on('show.bs.modal', function(e) {
var data = $(e.relatedTarget).data();
$('.title', this).text(data.recordTitle);
$('.btn-ok', this).data('recordId', data.recordId);
});
.modal.loading .modal-content:before {
content: 'Loading...';
text-align: center;
line-height: 155px;
font-size: 20px;
background: rgba(0, 0, 0, .8);
position: absolute;
top: 55px;
bottom: 0;
left: 0;
right: 0;
color: #EEE;
z-index: 1000;
}

Bootstrap 2.3
这是我在为 Bootstrap 2.3 模态回答这个问题时编写的代码的原始版本。
$('#modal').on('show', function() {
var id = $(this).data('id'),
removeBtn = $(this).find('.danger');
removeBtn.attr('href', removeBtn.attr('href').replace(/(&|\?)ref=\d*/, '$1ref=' + id));
});
