有了你已经证明信息的吝啬，这是最让我可以这样做：
(() =>
{
'use strict';
angular.module('app', [/**'ng-routing'**/])
.controller('DeviceController', [function()
{
var self = this;
// self.forms.new
// OR ... angular will handle this for me
// self.forms.edit
self.storage = {}; // to store raw data from service or anywhere, needed for the form initialization
self.storage.types = [{id: 1, label: 'Type 1'}, {id: 2, label: 'Type 2'}, {id: 3, label: 'Type 3'}, {id: 4, label: 'Type 4'}, {id: 5, label: 'Type 5'}];
self.storage.families = [{id: 1, label: 'Device 1'}, {id: 2, label: 'Device 2'}, {id: 3, label: 'Device 3'}, {id: 4, label: 'Device 4'}, {id: 5, label: 'Device 5'}];
self.events = {};
self.events.typeChanged = self.events.familyChanged = function()
{
self.storage.theThird = undefined; // this will be used to disable submit button while the value is not set, or any service result is waited to set the value
var type = self.data.type || 0;
var family = self.data.family || 0;
if (0 === (type * family) % 2) // you may implement any logic as needed. IF SYNTAX is just an example
{// this code executes only if the `id` at least one of `selected type` or `selected family` is even
self.storage.theThird = [{id: 2, label: '2016-02'}, {id: 4, label: '2016-04'}, {id: 6, label: '2016-06'}, {id: 8, label: '2016-08'}, {id: 10, label: '2016-10'}, {id: 12, label: '2016-12'}];
}
else
{
self.storage.theThird = [{id: 1, label: '2016-01'}, {id: 3, label: '2016-03'}, {id: 5, label: '2016-05'}, {id: 7, label: '2016-07'}, {id: 9, label: '2016-09'}, {id: 11, label: '2016-11'}];
}
}
}]);
})();
