我有以下打字错误在我的项目..让我分享一个样本,这样你就可以看到什么是处理。
module CoreWeb {
export class Controller implements IController {
public $q;
public $rootScope;
public $scope:ng.IScope;
public $state:ng.ui.IStateService;
public $translate:ng.translate.ITranslateService;
public appEvents;
public commonValidationsService;
public defaultPagingOptions = {
currentPage: 1,
pageSize: 10,
totalServerItems: 0,
maxSize: 5
};
public detailModelName:string;
public filter:string;
public listModelName:string;
public mode;
public modelDataService;
public modelDefaultProperty:string;
public ngDialog;
public notificationsService;
public pagingOptions:IPagingOptions;
public selectionStatus:boolean;

constructor(

) {
this.$q = $q;
this.$rootScope = $rootScope;
this.$scope = $scope;
this.$state = $state;
this.$translate = $translate;
this.appEvents = appEvents;
this.commonValidationsService = commonValidationsService;
this.detailModelName = detailModelName;
this.listModelName = listModelName;
this.modelDataService = modelDataService;
this.modelDefaultProperty = modelDefaultProperty;
this.ngDialog = ngDialog;
this.notificationsService = notificationsService;
this.serviceCreateFunction = serviceCreateFunction;
this.serviceGetAllCanceller = $q.defer();
this.serviceGetAllFunction = serviceGetAllFunction;
this.serviceGetOneFunction = serviceGetOneFunction;
this.serviceUpdateFunction = serviceUpdateFunction;
this.titleDataFactory = titleDataFactory;
this.mode = $rootScope.modeEnum.none;
this.pagingOptions = this.defaultPagingOptions;
this.selectionStatus = false;
this.showInactive = false;
this.tableAction = null;
this.tableActions = [
{id: 1, name: "Activate"},
{id: 2, name: "Deactivate"}
];
this.validationOptions = {showErrors: commonValidationsService.modes.property, showNotification: true};
this.activate();
}
这是扩展控制器类的类...其中之一
declare var App: ng.IModule;
module CoreWeb {
export class EntityMasterController extends Controller {
private currenciesDataSet;
private entity: IEntityMasterModel;
private merchandisingConstants;
private typeAheadOptions;
constructor(
$q:ng.IQService,
$rootScope,
$scope:ng.IScope,
$state,
$translate:ng.translate.ITranslateService,
appEvents,
commonValidationsService,
entityDataService,
merchandisingConstants,
ngDialog,
notificationsService,
titleDataFactory
) {
this.merchandisingConstants = merchandisingConstants;
super(
$q,
$rootScope,
$scope,
$state,
$translate,
appEvents,
commonValidationsService,
"entity",
null,
entityDataService,
"name",
ngDialog,
notificationsService,
"createEntity",
"getCurrentEntity",
"getEntity",
"updateEntity",
titleDataFactory
);
}
现在,如果我像上面那样在super调用之前初始化merchandisingConstants
,我会在gulp过程中得到以下错误,并且我的页面没有显示任何内容。当一个类包含初始化属性或参数属性时,super
调用必须是构造函数中的第一条语句。我已经尝试了所有我能想到的方法来修复这些错误,你知道我该怎么做吗?

当您扩充类别时,您的建构函式:
1.必须调用
super()
1.必须在执行其他操作之前执行此操作
在您的示例中,您只需要重新排序:

这是一个相当复杂的问题,但它是一个简单的解决方法:
它使用有点奇怪的JavaScript
,
运算符来填充赋值。实际上,您可以对任何参数执行此操作,但我对第一个参数执行了此操作。逗号运算符与分隔函数参数的逗号 * 不同 *,即使是完全相同的字符--让你把一个表达式列表串在一起,所有的表达式都将被计算。只有最后一个表达式被用作整个表达式的值。因此,通过这样做,你可以在参数列表求值的同时进行赋值。第一个参数的值仍然是
$q
,但赋值也会在函数调用super()
之前进行。
