使用Twitter Bootstrap确认模式/对话框中的删除? [英] Confirm deletion in modal / dialog using Twitter Bootstrap?

问题描述

我有一个与数据库行绑定的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.

I have an HTML table of rows tied to database rows. I'd like to have a "delete row" link for each row, but I would like to confirm with the user beforehand.

使用Twitter Bootstrap模式对话框有什么方法吗?

Is there any way to do this using the Twitter Bootstrap modal dialog?

获取食谱

对于此任务，您可以使用已经可用的插件和引导程序扩展.或者，您可以只用 3 行代码来弹出确认对话框.签出来.

GET recipe

For this task you can use already available plugins and bootstrap extensions. Or you can make your own confirmation popup with just 3 lines of code. Check it out.

说我们有此链接(请注意data-href而不是href)或我们要删除确认的按钮:

Say we have this links (note data-href instead of href) or buttons that we want to have delete confirmation for:

<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.它应该具有如下配置的确定"按钮:

Here #confirm-delete points to a modal popup div in your HTML. It should have an "OK" button configured like this:

<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即可确认删除操作:

Now you only need this little javascript to make a delete action confirmable:

$('#confirm-delete').on('show.bs.modal', function(e) {
    $(this).find('.btn-ok').attr('href', $(e.relatedTarget).data('href'));
});

因此show.bs.modal事件删除按钮href设置为具有相应记录ID的URL.

So on show.bs.modal event delete button href is set to URL with corresponding record id.

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.没有太多代码，它仍然非常简单.用这种方法看一下下面的演示:

I realize that in some cases there might be needed to perform POST or DELETE request rather then GET. It it still pretty simple without too much code. Take a look at the demo below with this approach:

// 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;
}

这是我在回答Bootstrap 2.3模态的这个问题时编写的代码的原始版本.

Here is an original version of the code I made when I was answering this question for Bootstrap 2.3 modal.

$('#modal').on('show', function() {
    var id = $(this).data('id'),
        removeBtn = $(this).find('.danger');
    removeBtn.attr('href', removeBtn.attr('href').replace(/(&|\?)ref=\d*/, '$1ref=' + id));
});
