我有一个与数据库行关联的HTML行表.我希望每行都有一个"删除行"链接，但我想事先与用户确认.
有没有办法使用Twitter bootstrap 模式对话框来实现这一点？

对于此任务，您可以使用已有的插件和 bootstrap 扩展.或者，您也可以只用3行代码来创建您自己的确认弹出窗口.看看这个.
假设我们有以下链接(注意data-href而不是href)或按钮，我们希望对其进行删除确认:
<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>
这里#confirm-delete点指向HTML中的模式弹出div.它应该有一个"确定"按钮，配置如下:
<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javascript就可以使删除操作成为可确认的:
$('#confirm-delete').on('show.bs.modal', function(e) {
$(this).find('.btn-ok').attr('href', $(e.relatedTarget).data('href'));
});
因此，在show.bs.modal上，事件删除按钮href被设置为具有相应记录id的URL.

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，没有太多的代码.请看下面使用此方法的演示:
// 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...';

以下是我为Bootstrap2.3模式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));
});
