jquery - 使用 Twitter Bootstrap 在模式/对话框中确认删除？

Question

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;
}

<br />

</button>

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));
});
