Javascript 在AngularJS中将元素添加到数组时，fnPtr不是一个函数

我有这个麻烦

我有一个复选框，当复选框被选中时，我想将3个对象加载到一个数组中，但当它发生时，我看到这个错误发生了六次：

错误：fnPtr不是一个函数

Parser.prototype.functionCall/is

$scope.marriage.children

可以直接使用，或者在通过

setSons

设置之前它不存在？如果看不到上下文源代码，也很难找到。我编辑了添加控制器代码的问题我也有同样的问题，除了错误have OPERATORS[“&&&]”是

$scope.marriage.children

可直接使用，或者它在

设置子
