Jquery-ui 自动完成和 Bootstrap 3 固定导航栏

Question

我正在尝试使用 jquery ui 和 twitter bootstarp 进行自动完成搜索。我在导航栏中添加了一个 facny 搜索框，一切似乎都运行良好。请查看下面的 代码片段 或者您也可以在 JSFiddle 上看到相同的代码，只需键入 'a' 它会自动在下拉列表。

问题出在 bootstrap 的平板电脑和移动版本的导航栏上，例如下面的代码片段默认显示平板电脑版本，因此 bootstarp 导航栏调整了它的高度，但是当我在平板电脑或移动版本上搜索时，自动完成结果留在固定位置的导航栏后面。我试图通过 z-index 和更改 .ui-autocomplete {position:relative;} 来解决这个问题，但对我来说没有任何效果。下面是这个问题的图片。

请看下面的代码片段，谢谢

$(function () {
        // Remove Search if user Resets Form or hits Escape!
  $('body, .navbar-collapse form[role="search"] button[type="reset"]').on('click keyup', function(event) {
   console.log(event.currentTarget);
   if (event.which == 27 && $('.navbar-collapse form[role="search"]').hasClass('active') ||
    $(event.currentTarget).attr('type') == 'reset') {
    closeSearch();
   }
  });

  function closeSearch() {
            var $form = $('.navbar-collapse form[role="search"].active')
      $form.find('input').val('');
   $form.removeClass('active');
  }

  // Show Search if form is not active // event.preventDefault() is important, this prevents the form from submitting
  $(document).on('click', '.navbar-collapse form[role="search"]:not(.active) button[type="submit"]', function(event) {
   event.preventDefault();
   var $form = $(this).closest('form'),
    $input = $form.find('input');
   $form.addClass('active');
   $input.focus();

  });
    });

请帮我解决这个问题。

Answer 1

将.ui-autocomplete的z-index设为2000

JSFiddle

Answer 2

您需要正确使用 important 关键字。类似于：

.ui-autocomplete { z-index:2000 !important; }
