Question

一整天都在试图说谎。希望一些新的眼睛可以得到它！

基本上我有一个范围：gridOrder，其中包含（ProdID：＆amp; Quantity :)。我使用产品ID从DB（数量和保留数量）获取数据。

然后我将它传递给一个计算某些数据的函数，并将所需的数据添加到另一个名为prodOrder []的作用域中。 prodOrder被赋予与等效gridOrder相同的索引（即如果gridOrder [2]然后创建了prodOrder [2]）。

如果我按时间顺序工作，一切正常，如gridOrder [0]，然后是gridOrder [1]但是如果我在gridOrder [x]并返回gridOrder [xa]（a＆gt; 1）它将不会更新gridOrder [xa]上的值。

如果有人能提供任何见解，我们将不胜感激。

Josh，你使用了错误的回调updValues的参数。

你可以尝试使用：

search_given_where.request(reservedStockRequest).success(function(data){
    updValues(data, key, value);
});

使用键和值的范围值。

Angular.forEach仅影响最后一行
