我正试图摆脱angular添加到模型值的$$ hashKey值。根据大多数实施轨道的来源应该解决这个问题,但我做错了。
vm.productTypes是id属性为GUID的任何对象数组。
产生的模型值......
while (rowPoint != NULL)
{
point = rowPoint->firstInRow;
while (point != NULL)
{
os << point->row;
os << ' ';
os << point->column;
os << ' ';
os << point->data;
os << endl;
point = point->right;
}
rowPoint = rowPoint->nextRow;
}
HTML代码:
$$hashKey: "object:445"
id: "9e695340-d10a-40ca-9cff-e9a93388912a"
name: "Medical"
type: 1
typeString: "ProductTypes"
我哪里错了?
更新
似乎name属性导致了这种奇怪的行为。错误? http://codepen.io/anon/pen/LNpMYJ

使用ng-model-options="{ trackBy: '$value.id' }"
。
$http
调用获取列表数据,请首先准备model
对象,然后加载列表数据。或者准备模型对象并放入一个保存孔形式数据的对象
