Question

我试图将我的控制器传递到另一个控制器并且我不断收到错误：[$ injector：unpr]未知提供者：MchControllerProvider＆lt; - MchController

如何将一个控制器正确注入另一个控制器？这是我的代码：

此部分是GroupMaintenanceBrowsePlansCtrl-＆gt;

(function () {
    'use strict';

    var controllerId = 'GroupMaintenanceBrowsePlansCtrl';

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

    function Controller($scope, datacontext, logger,mchService, MchController) {
    logger = logger.forSource(controllerId);

...

此部分是MchController - ＆gt;

'use strict';

myApp.controller('MchController', function ($scope, $routeParams, mchService, CustomerDataService, EntityInfoService, RatesDataService, RenewalGroupDataService) {
    console.log('reached MchController');
    //Rout parameters as passed via App.js
    $scope.routeParams = {
        type: $routeParams.Type,
        id: $routeParams.Id
    };

    //Properties associated with data
    $scope.visible = {
        experience: true,
        persistency: true,
    }

    // define view model and expose it to the scope
    var vm = {
        title: 'Loading MCH Name... ',
        CustomerNumber: 'Loading MCH Number...'
    };

    $scope.vm = vm; //local scope to MchController

    vm.type = $routeParams.Type;
    vm.id = $routeParams.Id;
    vm.togglePlans = togglePlans;
    vm.toggleRates = toggleRates;
    vm.getRateInformation = getRateInformation;
    vm.getMch6 = getMch6;
    vm.Mch2Information = [];
    vm.searchParameters = mchService.searchParameters;

    function togglePlans()
    {
        vm.expandedPlans = !vm.expandedPlans;
    }

    //Puts multiple sets of Mch2 data into array to iterate through
    vm.Mch2Information = new Array();
    vm.getEntityInformation = function () {
        getEntityInformation('MCH', mchService.searchParameters);
    }

    //Initialize GET command for Customer Information
    //getEntityInformation($routeParams.Type, $routeParams.Id);

    function getEntityInformation(type, id)
    {
        switch (type)
        {
            case "MCH": getCustomerInformation(id);
                    //getMch6();
                    getMch2Information(id);
        ....

您不能通过依赖注入将一个控制器注入另一个控制器，但您可以嵌套控制器并利用嵌套控制器之间的原型继承：

  <body ng-controller="MainCtrl">
    <div ng-controller="ChildCtrl">
      <p>Hello {{name}}!</p>
      <button ng-click="parentAction()">parent action</button>
      <button ng-click="overriddenAction()">overriden action</button>
    </div>
  </body>

js code：

app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';
  $scope.parentAction = function () {
    alert('greetings from parent controller')
  };
  $scope.overriddenAction = function () {
    alert('greetings from parent controller');
  };
});

app.controller('ChildCtrl', function ($scope) {
  $scope.overriddenAction = function () {
    alert('greetings from child controller');
  };
})

这样您就可以访问父控制器上定义的函数和对象。或者您可以事件覆盖这些对象或函数。

您无法将控制器注入另一个控制器。如果两个控制器之间存在共享逻辑，则将其放入服务中并将其注入控制器。

理想情况下，您的控制器应该尽可能地薄，并且业务逻辑的大多数（如果可能的话）都应该驻留在服务中。
