Ruby on Rails Gemfile开发和Javascript

I'm working on porting a JS library to rails. This will be my first gem that I'm attempting to create and I seem to have run into a bit of a snag.

我正在努力将JS库移植到rails。这将是我尝试创建的第一个宝石，我似乎遇到了一些障碍。

The issue that I have is that there will necessarily be some JavaScript elements to the gem. However, I seem to be unable to find out how to do this.

我遇到的问题是gem必然会有一些JavaScript元素。但是，我似乎无法找到如何做到这一点。

Example:

例：

/lib/rotrails.rb

/lib/rotrails.rb

module RotRails
    def self.isSupported
        #Call JS function "isSupported() in /vendor/assets/javascript/rotrails.js
    end
end

/vendor/assets/javascript/rotrails.js

/vendor/assets/javascript/rotrails.js

Function isSupported() {
     return !!(document.createElement("canvas").getContext && Function.prototype.bind);
}

Any assistance on how to solve this problem as well as pass the result back to the Rails Gem would be appreciated.

任何有关如何解决此问题以及将结果传递回Rails Gem的帮助将不胜感激。

Update: To clarify, the rails part is logic calculations and the JavaScript is the frontend for the program. I am looking for the most logical way to have the two communicate or a reference to how to work with JavaScript when creating gemfiles.

更新：为了澄清，rails部分是逻辑计算，JavaScript是程序的前端。我正在寻找最合乎逻辑的方式来进行两者沟通，或者在创建gemfiles时参考如何使用JavaScript。

Thanks!

谢谢！

Did you consider to use (or simply try) https://rails-assets.org/ instead of porting your js library manually ?

您是否考虑过使用（或只是尝试）https://rails-assets.org/而不是手动移植您的js库？
