Question

我正在尝试使用按钮获得水平滚动。我有一个容器，其中有几个水平放置的元素（可以大于3，从后端获取值），我想使用按钮滚动浏览它们。我也想在没有滚动条时隐藏那些按钮。

这是非常容易且有用的：

angular.module('anchorScrollOffsetExample', [])
.run(['$anchorScroll', function($anchorScroll) {
  $anchorScroll.yOffset = 50;   // always scroll by 50 extra pixels
}])
.controller('headerCtrl', ['$anchorScroll', '$location', '$scope',
  function($anchorScroll, $location, $scope) {
    $scope.gotoAnchor = function(x) {
      var newHash = 'anchor' + x;
      if ($location.hash() !== newHash) {
        // set the $location.hash to `newHash` and
        // $anchorScroll will automatically scroll to it
        $location.hash('anchor' + x);
      } else {
        // call $anchorScroll() explicitly,
        // since $location.hash hasn't changed
        $anchorScroll();
      }
    };
  }
]);

body {
  padding-top: 50px;
}

.anchor {
  border: 2px dashed DarkOrchid;
  padding: 10px 10px 200px 10px;
}

.fixed-header {
  background-color: rgba(0, 0, 0, 0.2);
  height: 50px;
  position: fixed;
  top: 0; left: 0; right: 0;
}

.fixed-header > a {
  display: inline-block;
  margin: 5px 15px;
}
