选项卡下拉菜单在引导保持关闭时，单击导航药丸

我在bootstrap中创建包含"注册"answers"登录"表单的选项卡下拉菜单时遇到问题，但每次我单击选项卡时，它们都会关闭。我不明白为什么。我试过流行的e.p stopproprogate()，但它似乎不适合我。任何帮助都会很感激。

                          </div>
                          <!--tab pane login-->
                      </div>
                      <!--tab content-->
                  </ul>
                  <!-- myTabs ul-->
                  <ul class = "pull-right"><a href="#"><span class=" glyphicon glyphicon-shopping-cart"></span></a></ul>
              </div>
              <!--myDropdown-->
          </form>
      </div><!--container-->
  </div><!--container fluid-->

这是我的javascript:

    <script>
    $('.dropdown-menu a[data-toggle="tab"]').click(function (e) {
        e.stopPropagation()        
        $(this).tab('show')
    })
    </script>
