Client-side functionality for the Helpful/Not Helpful buttons

[NateWr]

Assigned: @Yjohn

To implement the client-side functionality, you'll need to write everything that happens on the user side when they click the Helpful/Not Helpful buttons, and handle the response from the server.

• When a user clicks one of the buttons, add an indication that the request is in process. (Read about CSS Animation and look at this loading spinner example).
• Submit a POST ajax request to /rating containing the data keys entryId and isHelpful.
• When the response is received from the server, use the data to update the helpful display.

Some resources which might help you:

• Using event listeners
• Making ajax requests

You'll need to work closely with @khaledkzy because this issue depends on #7.
