我ng-include用来切换不同的数据页面，这会做大量的数据渲染。
我发现浏览器的内存使用量一直在增长，而且永远不会回落。
代码
代码非常简单。
HTML 代码：
<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>
它将显示一个“无数据”按钮和 10 个数据按钮来加载不同的页面。
角码：
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>
和“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live demo时，初始化内存使用量小于100M。然后我点击“加载数据”按钮，它很快就会增长到300M并且永远不会回退，即使我点击“无数据”按钮加载“nodata.html”。
正常吗？ng-include有内存泄漏还是我遗漏了什么？或者内存使用情况很好，我不需要担心？
截屏
我创建了一个截屏视频来展示它：
