模态框编辑的话 

需要先获取数据  获取数据的方式有2种 一种是获取页面上的数据 传递过去

然后是用ajax获取数据，给弹窗赋值

下面说第一种  第一步  数据展示部分  添加编辑按钮呢

            @foreach ($tasks as $task)
              <tr>
                <td>{{$task->name}}</td>
                <td>{{str_limit($task->body,30)}}</td>
                <td>{{$task->status}}</td> {{-- Umformulierung in den Status!!! --}}
                <td>{{$users[($task->user_id)-1]->name}}</td> {{-- Umformulierung in den Namen --}}
                <td>{{$task->milestone->name}}</td>
                <td>{{$task->duedate}}</td>
                <td>

                  <button data-name="{{$task->name}}" data-body="{{$task->body}}" data-username="{{$users[($task->user_id)-1]->name}}" data-milestone="{{$task->milestone->name}}" data-duedate="{{$task->duedate}}" data-id="{{$task->id}}" class="btn btn-success"   data-toggle="modal" data-target="#tasksUpdate" >edit</button>

                  </td>

              </tr>
            @endforeach

循环获取的数据 进行编辑  把值用data-*得形式进行传递

对应的JS函数 使用show.bs.modal

代码如下   第二部 JS相关代码

   <script>

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

                      var button = $(event.relatedTarget); // Button that triggered the modal
                      var id = button.data('id');
                      var name = button.data('name'); // Extract info from data-* attributes
                      var body = button.data('body'); // Extract info from data-* attributes
                      var username = button.data('username'); // Extract info from data-* attributes
                      var milestone = button.data('milestone') ;// Extract info from data-* attributes
                     var duedate = button.data('duedate'); // Extract info from data-* attributes

                      var modal = $(this);
                      modal.find('.hiddenId').val(id);
                      modal.find('.name').val(name);
                      modal.find('.body').val(body);
                      modal.find('.datetimepickeredit').val(duedate);
                  })
               });

        </script>

3   看下模态框的代码 

<!-- Modal tasks-->
<div class="modal fade" id="tasksUpdate"  tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">

      </div>
      <div class="modal-body">

                <option value="{{$u->id}}">{{$u->name}}</option>
              @endforeach

              @foreach ($meilensteine as $ms)
              <option value="{{$ms->id}}">{{$ms->name}}</option>
                @endforeach
            </select>
          </div>
          <div class="form-group">

              <input type="text" class="form-control pull-right datetimepickeredit" id="datetimepickeredit" style="100%;" name="duedate" required/>
            </div>
          </div>
          {{-- Einbindung einer notwenidigen js-Datei und "Aktivierung" des Kalendars der in dem input-Tag mit id:datetimepicker integriert ist--}}
          <script src="{{ URL::asset('js/jquery.datetimepicker.full.js')}}"></script>
          <script>
            $("#datetimepickeredit").datetimepicker();
            {{-- 脛ndern der Einstellung, damit die Monate in Deutsch angezeigt werden --}}
            jQuery.datetimepicker.setLocale('de');
          </script>
      <div class="modal-footer">

        <input type="submit" class="btn btn-primary" value="脛nderungen speichern">
      </div>
    </form>
    </div>
  </div>
  </div>                  

主要是这3块内容，这个模态框折腾了 好久  幸好给解决了
