[英]Angular 1.5 + TypeScript Directive with Controller
I'm trying to create a directive with controller using Angular 1.5 and TypeScript 1.8 but it won't work for me. 我正在尝试使用Angular 1.5和TypeScript 1.8使用控制器创建指令,但它对我不起作用。 I looked at a bunch of examples but I am following those examples to the tee and it still won't work for me.
我看了很多例子,但我在发球台上遵循了这些例子,但它仍然对我不起作用。 Am I cursed?
我被诅咒了吗?
Here is the code: 这是代码:
export class FooController implements angular.IController {
static $inject = ['myService', '$state'];
constructor(private myService: Services.MyService, private $state: angular.ui.IStateService) {
}
public foo: Services.Dtos.Foo;
public bar;
$onInit() {
if (!this.foo) return;
this.bar = this.$state.href('app.bar', {id: this.foo.id});
}
}
export class FooDirective implements angular.IDirective {
public restrict = 'E';
public replace = true;
public scope = {};
public templateUrl = 'content/templates/foo.template.html';
public controller = FooController;
public controllerAs = 'ctrl';
public bindToController = {
foo: '<',
};
}
It errors on FooDirective
saying the following: 它在
FooDirective
显示以下错误:
What am I doing wrong? 我究竟做错了什么?
UPDATE 2017/02/15 IDirective looks like this (from angular.d.ts file): 更新2017年2月 15日IDirective看起来像这样(来自angular.d.ts文件):
interface IDirective {
compile?: IDirectiveCompileFn;
controller?: string | Injectable<IControllerConstructor>;
controllerAs?: string;
/**
* @deprecated
* Deprecation warning: although bindings for non-ES6 class controllers are currently bound to this before
* the controller constructor is called, this use is now deprecated. Please place initialization code that
* relies upon bindings inside a $onInit method on the controller, instead.
*/
bindToController?: boolean | {[boundProperty: string]: string};
link?: IDirectiveLinkFn | IDirectivePrePost;
multiElement?: boolean;
priority?: number;
/**
* @deprecated
*/
replace?: boolean;
require?: string | string[] | {[controller: string]: string};
restrict?: string;
scope?: boolean | {[boundProperty: string]: string};
template?: string | ((tElement: JQuery, tAttrs: IAttributes) => string);
templateNamespace?: string;
templateUrl?: string | ((tElement: JQuery, tAttrs: IAttributes) => string);
terminal?: boolean;
transclude?: boolean | 'element' | {[slot: string]: string};
}
The directive should be a function that returns a configuration object. 该指令应该是一个返回配置对象的函数。 I would write the directive like this:
我会这样写指令:
export const fooDirective = (): angular.IDirective => {
return {
restrict: 'E',
replace: true,
scope: {},
templateUrl: 'content/templates/foo.template.html',
controller: FooController,
controllerAs: 'ctrl',
bindToController: {
foo: '<'
}
};
};
I would also recommend you take a look at the new component API. 我还建议您看看新的组件API。 It greatly simplifies creating new components, and it uses many best practices by default, such as
controllerAs
. 它极大地简化了创建新组件的过程,并且默认情况下使用了许多最佳实践,例如
controllerAs
。

It seems to be the problem with TypeScript definition only accepting boolean. TypeScript定义仅接受布尔值似乎是一个问题。
export class FooDirective implements angular.IDirective {
public restrict = 'E';
public replace = true;
public scope = {};
public templateUrl = 'content/templates/foo.template.html';
public controller = FooController;
public controllerAs = 'ctrl';
public bindToController:any = {
foo: '<',
};
}
This would fix the error, on the other hand it won't typecheck bindToController. 这样可以修复错误,但另一方面,它不会类型检查bindToController。
