Executing a Ruby method on a server using JavaScript - A guide

I'm facing a seemingly simple issue that I can't seem to find a clear solution for anywhere. Essentially, I have a JavaScript application hosted on a server that requires passing information between the JS app and a Rails-built server. The process involves the JS app triggering a function on the server to generate certain values, and then receiving these values back to be utilized in the JS app. This communication loop continues throughout the entire session of the application.

Is there a straightforward way to achieve this? I understand that Ajax plays a role in it, but I'm struggling to piece together how.

Answer №1

Indeed, the solution involves utilizing ajax functionality. If you are working with jQuery, you will need to make a request to the server in the following manner:

$.ajax({ 
    type: "GET", 
    url: '/get_info_action',  
    data: {some_data: some_value}, 
    dataType: "script" 
});

Ensure that the URL value is properly configured in your routes.rb file. I found a helpful Railscast on this topic which greatly assisted me in grasping these concepts:
