javascript - 通过依赖注入(inject)在 Controller 之间传递 $routeParams

Question

我想知道如何将此 Controller 范围内的变量传递给另一个 Controller 。我想要做的就是获取 vm.search (searchParameters) 并将其传递给另一个 Controller 。

///

(函数(){ '使用严格';

var controllerId = 'GroupMaintenanceBrowsePlansCtrl';

angular.module('myApp').controller(controllerId, ['$scope', 'RenewalGroupDataService', 'logger', Controller]);

function Controller($scope, datacontext, logger) {
    logger = logger.forSource(controllerId);
    var logError = logger.logError;
    var logSuccess = logger.logSuccess;
    var logWarning = logger.logWarning;

    var vm = {};
    $scope.vm = vm;

    vm.getPlans = getPlans;
    vm.plans;
    vm.loadingPlans = false;


    vm.pageSize = 100;

    function getPlans(searchParameters) {
        vm.loadingPlans = true; vm.search = searchParameters;

        datacontext.getAssignedPlans(searchParameters, vm.pageSize).then(function (plans) {
            vm.plans = plans;

      //Compares which columns are being populated for choosing which headings to show
        if (vm.search.MchNumber != null 
            ||vm.search.ContractNumber != null 
            || vm.search.PlanCode != null)
        {

            vm.detail = true;
        }

        if (vm.search.DivisionName != null
            || vm.search.PoolName != null
            || vm.search.SubpoolName != null
            || vm.search.RenewalGroupName != null)
        {
            vm.detail = false;
        }

            //Sets values to NULL after every search is performed
       vm.search.MchNumber =
       vm.search.ContractNumber =
       vm.search.PlanCode =
       vm.search.DivisionName =
       vm.search.PoolName =
       vm.search.SubpoolName =
       vm.search.RenewalGroupName = null;

        }).finally(function () { vm.loadingPlans = false; });
    }
};

})();

要使用两个 Controller 之间的值，您可以使用两个 Controller 注入(inject)的服务。

例如

root.service("MyService", function () {});

将MyService注入(inject)每个 Controller 。然后两个 Controller 将使用相同的实例(因为服务是单例)，因此您对该服务所做的任何更改都将被共享。

您还可以将服务放在 $scope 上并使用模板绑定(bind)。但就你而言，我认为这无关紧要。
