如何使用视图ng-model的不同参数再次运行控制器功能

Question

我有一个控制器在初始加载时工作良好。它调用user[0]数据，一切都处理得很好。当我改变dropdown时，我想调用相同的函数，但我无法让整个控制器重新加载。它从函数调用开始，并在初始加载时提取正确信息(linkToken等)的地方留下未定义。是否有一种方法可以让它从控制器重新加载所有数据，而不仅仅是从函数?

从视图调用testchange()传递新数据后，我得到:类型错误:无法读取未定义的属性"locations"在h。美元范围。updateLocations (refillController.js: 261)在refillController.js: 73

但是，当我调用在初始页面加载时运行的原始getRefills()时，我得到相同的错误。我如何定义这些，以便在onchange(0)之后加载?

$scope.userInfoArr.splice(0, 0, {'Name': $scope.user.FirstName, 'LinkToken': $scope.user.LinkToken});

检查refillsService是否返回正确的数据，可能是$scope.refills仍然是空数组
