Question

当面板打开时，我需要将其滚动回＆＃34; .panel-title＆＃34;刚刚点击的那个。我知道我可以创建一个指令来执行此操作，例如（从this site获得此信息）：

.directive( 'scrollTop', scrollTop );

  function scrollTop() {
      return {
          restrict: 'A',
          link: link
      };
  }

  function link( $scope, element ) {
      $scope.collapsing = false;
      $scope.$watch( function() {
          return $(element).find( '.panel-collapse' ).hasClass( 'collapsing' );
      }, function( status ) {
          if ( $scope.collapsing && !status ) {
              if ( $(element).hasClass( 'panel-open' ) ) {
                  $( 'html,body' ).animate({
                      scrollTop: $(element).offset().top - 20
                  }, 500 );
              }
          }
          $scope.collapsing = status;
      } );
  }

在我应该使用的HTML中：

<div uib-accordion-group is-open="status.openPanel" scroll-top></div>

但这似乎不起作用。单击第二个面板时，它会打开第一个和第二个面板，打开第三个面板时它甚至不会滚动到顶部。

我只需要它滚动回＆＃34; .panel-title＆＃34;被点击的面板。我认为，当面板内容很长时间以来，这似乎很难做到这一点非常荒谬，我想大多数人都希望在面板打开时滚动到信息的顶部。 / p>

我在这里看过其他帖子，但他们似乎并没有处理AngularJS。我正在使用＆＃34; ui-bootstrap-tpls-2.1.3＆＃34;

这可能是一种快速而肮脏的方法，但可以完美无缺

.accordion {
  max-height: 220px;
  overflow: auto;
  padding: 2px; 8px 0 0;
}
*:focus { outline: none !important; }
