Bootstrap模态关闭按钮

Question

我在bootstrap中关闭模式有问题.当我用数据打开模态窗口时(根据触发按钮改变模态内容).这是http://getbootstrap.com/javascript/#modals中的示例

<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@mdo">Open modal for @mdo</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@fat">Open modal for @fat</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="@getbootstrap">Open modal for @getbootstrap</button>
...more buttons...

<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="exampleModalLabel">New message</h4>
      </div>
      <div class="modal-body">
        <form>
          <div class="form-group">
            <label for="recipient-name" class="control-label">Recipient:</label>
            <input type="text" class="form-control" id="recipient-name">
          </div>
          <div class="form-group">
            <label for="message-text" class="control-label">Message:</label>
            <textarea class="form-control" id="message-text"></textarea>
          </div>
        </form>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" id="btnclose" data-dismiss="modal">Close</button>
        <button type="button" id="btnsend" class="btn btn-primary">Send message</button>
      </div>
    </div>
  </div>
</div>

这没关系,但如果我关闭模态并在其他按钮中打开,当单击发送按钮打印在控制台日志中时,第一个模态和此模态的收件人值.但我只需打印最后一个收件人值.我不明白为什么以前模态的堆栈事件关闭.对于这两个按钮,这是我的jquery代码:

    $('#exampleModal').on('show.bs.modal', function (event) {

    var button = $(event.relatedTarget) // Button that triggered the modal
    var recipient = button.data('whatever') // Extract info from data-* attributes
    // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
    // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
    var modal = $(this)
    modal.find('.modal-title').text('New message to ' + recipient)
    modal.find('.modal-body input').val(recipient)

    $("#btnsend").one("click", function(){
        console.log('Pinchado')
      console.log(recipient)
    })

    $("#btnclose").one("click", function(){
        console.log('Cerrando...')
    })

    $('#exampleModal').on('hidden.bs.modal', function (e) {
      console.log('Cerrada');
    })

  })

非常感谢你,我希望有人能帮助我. https://jsfiddle.net/DTcHh/28480/

这是您或您可以说传统方式的旧方式.它还有答案.只需绑定hide并单击show event bind之外的eventd.

$('#exampleModal').on('show.bs.modal', function(event) {

   var button = $(event.relatedTarget) // Button that triggered the modal
   var recipient = button.data('whatever') // Extract info from data-* attributes
     // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
     // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
   var modal = $(this)
   modal.find('.modal-title').text('New message to ' + recipient)
   modal.find('.modal-body input').val(recipient)
 })
 
 $("#btnsend").on("click", function() {
     console.log('Pinchado')
     console.log(recipient)
   })

   $("#btnclose").on("click", function() {
     console.log('Cerrando...')
   })

   $('#exampleModal').on('hidden.bs.modal', function(e) {
     console.log('Cerrada');
   })

      </div>
    </div>
  </div>
</div>

以下是现代的做法.您可以参考此链接以获取有关动态创建模态的方式的更多详细信息.

function open_modal(name) {

  var message = $('#frm_1');
  BootstrapDialog.show({
    title: 'New message to ' + name,
    message: $('#frm_1'),
    onshown : function() {
      $('#recipient-name').val(name);
    },
    onhide : function(dialog) {
      $('#hidden-div').append(message);
    },
    buttons: [{
      label: 'Close',
      action: function(dialog) {
        dialog.close();
      }
    }, {
      label: 'Send message',
      cssClass: 'btn btn-primary',
      action: function(dialog) {
        // Do whatever send message does, here
      }
    }]
  });
