如何在Meteor中的lib / constants.js文件中访问常量？ [英] How can I access constants in the lib/constants.js file in Meteor?

问题描述

我按照文档将常量放在 lib / constants.js 文件中。

问题：
如何在客户端访问这些常量 html 和 js

解决方案

您将需要使其成为全局变量，以便其他文件可以看到它们。 p>

JavaScript

/lib/constants.js

  THE_ANSWER = 42; //注意缺少var 
  

/client/some-other-file.js

  console.log（THE_ANSWER）; 
  

---

CoffeeScript

/lib/constants.coffee

  @THE_ANSWER = 42 
  

/client/some-other-file.coffee

  console.log THE_ANSWER 
  

I followed the documentation to put the constants in the lib/constants.js file.

Question: How to access these constants in my client side html and js files?

解决方案

You will need to make them global variables in order for other files to see them.

JavaScript

/lib/constants.js

THE_ANSWER = 42; // note the lack of var

/client/some-other-file.js

console.log(THE_ANSWER);

---

CoffeeScript

/lib/constants.coffee

@THE_ANSWER = 42

/client/some-other-file.coffee

console.log THE_ANSWER
