第三方声明文件§ 当然,jQuery 的声明文件不需要我们定义了,社区已经帮我们定义好了:jQuery in DefinitelyTyped。 我们可以直接下载下来使用,但是更推荐的是使用@types统一管理第三方库的声明文件。 @types的使用方式很简单,直接用 npm 安装对应的声明模块即可,以 jQuery 举例: 代码语言:javascript 代码运行次数:0 复制...
JavaScript is a dynamically typed language. While this makes declaring variables easy, it can in some cases lead to unexpected results. The static type system in TypeScript enables you to describe the shape of an object, providing better documentation, and allowing TypeScript to validate that your...
After changing the extension to*.gtsthe code stopped working correctly. As a result of debugging, I noticed thatthis.interactivecontainsundefinedinstead of a boolean value. Looking at the prototype of the object, I noticed that the class actually overrides theinteractivefield, although the*.tsfiles...
