该表是通过在行模板上进行ng重复创建的.我需要做一些所有涉及到访问由ng-repeat创建的范围的事情.我需要

>检测行是否可编辑,何时不可编辑
>当第一个下拉列表更改时,过滤第二个丢弃列表的选项

为了尝试使用此演示,我已经为单独的行添加了一个控制器.这给了我一些访问窗体(name = rowform),但是我仍然无法在“make”属性上设置一个手表.当用户进行选择时,我甚至不能发现表单的属性正在改变.

如何在“make”属性上设置手表？

页面控制器

angular.module('app').controller("quoteBuckingRaterController",function ($scope,$q,$filter,listService,transactionDataService) {

        $scope.equipment = []; 
        $scope.makes = [];

            if(equip.model) {

                return selected.length ? selected[0].name : 'Not set';
            } else {
                return 'Not set';
            }

                id: $scope.equipment.length+1,name: '',make: null,model: null 
            };
            $scope.equipment.push($scope.inserted);
        };

        $scope.filterModels = function (make) {
            $scope.models = _.where($scope.allModels,function(item) {
                return item.make == make;
            });
        };

        //called by another process when page loads
        $scope.initialize = function (loaded) {
            return $q(function (resolve,reject) {
                if (!loaded) {
                    listService.getEquipmentModels().then(function (data) {
                        $scope.allModels = data;
                        $scope.models = data;

                        //uses underscore.js
                        $scope.makes = _.chain(data)
                                        .map(function (item) {
                                            var m = {
                                                id: item.make,name: item.make

                                            return m;
                                        })

                }

        }

行控制器

angular.module('app').controller("editRowController",function ($scope) {
    $scope.testClick = function () {
        alert('button clicked');
    };

    $scope.make = null;

    $scope.$watch('make',function () {
        alert('how do I tell when the make has been changed?');
        this.$parent.$parent.filterModels(make.id);
    });
});
