内存泄漏 – ng-include是否有内存泄漏？

我使用ng-include来切换不同的数据页面,这些页面将进行大量的数据渲染.

我发现浏览器的内存使用量不断增长,并且永远不会退缩.

码

代码很简单.

<body ng-controller="MainCtrl">
  <div>
    <button ng-click="url='nodata.html'">No data</button>
    <button ng-repeat="i in getNumArray(10)" ng-click="loadData(i)">Load data {{i}}</button>
  </div>
  <hr/>
  [{{url}}]
  <div ng-include="url"></div>
</body>

它将显示“无数据”按钮,以及10个数据按钮来加载不同的页面.

角度代码：

app.controller('MainCtrl',function($scope) {
  $scope.url = "nodata.html";
  $scope.loadData = function(n) {
    $scope.url = "data" + n + ".html";
  }

  $scope.getNumArray = function(n) {
    var arr = [];
    for(var i =0;i<n;i++) {
      arr.push(i);
    }
    return arr;
  }
});

app.controller('DataCtrl',function($scope,$http){
  $http.get('data.json').success(function(data){
      $scope.data = data;
  })
});

和“datan.html”页面：

<div ng-controller="DataCtrl">
  <table ng-repeat="x in getNumArray(500)">
    <tbody>
      <tr>
        <td>{{data["key0"]}}</td>
        <td>{{data["key1"]}}</td>
        <td>{{data["key2"]}}</td>
        <td>{{data["key3"]}}</td>
        <td>{{data["key4"]}}</td>
        <td>{{data["key5"]}}</td>
        <td>{{data["key6"]}}</td>
        <td>{{data["key7"]}}</td>
        <td>{{data["key8"]}}</td>
        <td>{{data["key9"]}}</td>
      </tr>
    </tbody>
  </table>
</div>

“nodata.html”页面：

<div>No data yet.</div>

而“data.json”：

{
  "key0": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f","key1": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f","key2": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f","key3": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f","key4": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f","key5": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f","key6": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f","key7": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f","key8": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f","key9": "sdf sdf sdf sdf sdf sdf sdf sdf sdf sd fds fds fsd fds fds fds fds fsd fds fds f"
}

这是一个现场演示：

当我用chrome打开实时演示时,初始化内存使用量小于100M.然后我点击“加载数据”按钮,即使我点击“无数据”按钮加载“nodata.html”,它也会很快增长到300M并且永不退缩.

这是正常的吗？ ng-include是否有内存泄漏或我遗漏了什么？或者内存使用情况很好,我不需要担心它？

截屏

我创建了一个截屏视频来展示它：

解决方法

尝试升级到1.0.5版.它似乎没有这个问题. 我相信这是因为当模板中存在顶级空白节点时,1.0.3 / 4中存在内存泄漏.
