AngularJS：嵌套数组和视图更新(AngularJS: nested array and view update)

在$scope更新Array内的Array后，我在更新视图时遇到问题。

首先，我检查Array成员是否已经存在：

$scope.myArray = []; if(typeof $scope.myArray[someIndex] == 'undefined') { $scope.myArray[someIndex] = { name: someName, data: [] }; }

然后推送到$scope.myArray[someIndex].data ：

$scope.myArray[someIndex].data.push(dataContent);

此时视图不会更新。

当然，如果我直接推送到$scope.myArray它。 有什么建议么？

I'm having problems updating the view after an Array inside an Array is updated in the $scope.

First i check if the Array member already exists:

$scope.myArray = []; if(typeof $scope.myArray[someIndex] == 'undefined') { $scope.myArray[someIndex] = { name: someName, data: [] }; }

Then push to $scope.myArray[someIndex].data:

$scope.myArray[someIndex].data.push(dataContent);

At this point the view does not update.

Of course if i directly push to $scope.myArray it does. Any suggestions?

它看起来比它简单。

根据这里的响应，我设置了一个允许设置字符串键的关联数组。 如果将数组声明为=[] ，则无法将字符串设置为键。

所以我只是将我的声明$scope.myArray=[]更改$scope.myArray={}并且$scope.myArray={} ，它有效。

It was simpler than it looked.

Based on the response here i am setting an associative array which allows set string keys. If you declare your array as =[] you simply cannot set strings as keys.

So i just changed my declaration $scope.myArray=[] to $scope.myArray={} and voilà, it works.
