[英]Angular 2.0 : Does Typescript support all the features of ES6?
[英]Using typescript for ES6 support, with Angular JS
我正在寻找可以为我提供以下内容的编译器:
现在,大多数内容都由TypeScript覆盖,但是Typescript带有自己的类型语法,我不喜欢使用它,因为它似乎需要我下载/设置接口/定义文件。
我玩过它,但没有取得太大的成功。 您可以在下面看到代码。 有人可以建议一个替代方法(不,我不想使用Dart),或者告诉我我做错了什么。
app.ts(我的“主”文件)
/// <reference path="MyController.ts"/>
/// <reference path="MyService.ts"/>
// <reference path="../bower_components/angular/angular.min.js"/>
angular.module("test")
.controller("MyController", MyController.injections)
.factory("MyService", MyService.injections);
MyController.ts
/// <reference path="MyService.ts"/>
module MyController {
class MyController {
constructor(MyService) {
this.MyService = MyService;
}
callSomething() {
this.MyService.doSomething();
}
}
export var injections = [ "MyService", MyController ];
}
MyService.ts
module MyService {
export class MyService {
constructor($http) {
}
doSomething() {
console.log("Yo");
}
}
export var injections = [ "$http", MyService ];
}
以下是打字稿编译器输出的问题:

我认为这个参考:
// <reference path="../bower_components/angular/angular.min.js"/>
实际上应该是Angular的.d.ts
类型定义文件。
在本课程中:
class MyController {
constructor(MyService) {
this.MyService = MyService;
}
您尝试使用this.MyService
但从未声明过。
class MyController {
MyService: MyService.MyService;
constructor(MyService) {
this.MyService = MyService;
}
-或者-您可以像下面这样自动将构造函数参数设置为类变量:
class MyController {
constructor(private MyService: MyService.MyService) {
}
