从 TypeScript 声明全局命名空间变量 [英] declare global namespace variable from TypeScript

问题描述

如何在打字稿的全局命名空间中显式声明一个变量?

How to explicitly declare a variable in the global namespace from typescript?

我需要编译器生成以下 javascript 代码:

I need the compiler to generate the following javascript code:

MyExtension = someFunction()

不幸的是，我只能让它生成

unfortunately, I can only have it generate

var MyExtension = someFunction()

这涉及到最新版本的流星包(仍在 rc 中)的问题.Meteor 引入了一种在包中定义命名空间范围的方法——问题是，变量需要在全局命名空间中定义(流星重新路由到它自己的包对象).

This comes to an issue with the latest version (still in rc) of meteor packages. Meteor introduced a way to scope namespaces in packages - the issue is, the variable needs to be defined in the global namespace (which meteor reroutes to its own Package object).

是否有某种global 关键字可用或在计划中?

Is there some kind of global keyword available or in the plans?

推荐答案

使用 declare 关键字.这些被称为环境声明.

Use the declare keyword. These are known as ambient declarations.

declare var MyExtentention:any;
