Question

根据我的理解，$ anchorScroll yOffset在子元素中是不可能的： “为了使yOffset正常工作，应该在文档的根目录上进行滚动，而不是某些子元素。” https://docs.angularjs.org/api/ng/service/ $ anchorScroll

示例（从AngularJS文档修改）：我想点击一个链接，并在滚动到的内容之上加上“之间”一词。

的index.html

<body ng-app="anchorScrollOffsetExample">
    <div class="fixed-header" ng-controller="headerCtrl">
    <a href="" ng-click="gotoAnchor(x)" ng-repeat="x in [1,2,3,4,5]">
      Go to inner-anchor {{x}}
    </a>
  </div>
  <div id="anchor" class="anchor">
    <div ng-repeat="x in [1,2,3,4,5]">
        between
        <div id="innerAnchor{{x}}" class="anchor" >Inner-Anchor {{x}} of 5</div>
    </div>
  </div>
</body>

的style.css

  .anchor {
    border: 2px dashed DarkOrchid;
    padding: 10px 10px 200px 10px;
    max-height:500px;
    overflow-y: auto;
  }

的script.js

angular.module('anchorScrollOffsetExample', [])
.run(['$anchorScroll', function($anchorScroll) {
  $anchorScroll.yOffset = 500;
}])
.controller('headerCtrl', ['$anchorScroll', '$location', '$scope',
  function ($anchorScroll, $location, $scope) {
    $scope.gotoAnchor = function(x) {
      var newHash = 'anchor' + x;
      if ($location.hash() !== newHash) {
        $location.hash('innerAnchor' + x);
      } else {
        $anchorScroll();
      }
    };
  }
]);

有没有一种很好的方法可以在AngularJS中执行此操作（最好不使用jQuery或其他库）而不将“介于”内部移动到我正在滚动到的DIV内部？

为什么不使用锚标记？

<body ng-app="anchorScrollOffsetExample">
    <div class="fixed-header" ng-controller="headerCtrl">
    <a href="" ng-click="gotoAnchor(x)" ng-repeat="x in [1,2,3,4,5]">
      Go to inner-anchor {{x}}
    </a>
  </div>
  <div id="anchor" class="anchor">
    <div ng-repeat="x in [1,2,3,4,5]">
        <!-- Add an anchor above the text, and we scroll here instead of the div -->
        <a name="innerAnchor{{x}}"></a>
        between
        <div class="anchor" >Inner-Anchor {{x}} of 5</div>
    </div>
  </div>
</body>
