I want to change the click event by the value of json in zabuto calendar

There is a plug-in that runs on bootstrap (+jQuery) called zabuto calendar.

The default behavior is

(1) Monthly Calendar Display
(2)If you have event data in JSON format, the background color will be displayed on the appropriate date and will be clickable.
(3)Click the clickable date and a modal window will fall.In the modal window, JSON data and HTML can be described.You can also write hyperlinks, so you can click on them to move to another page (e.g., skip to the detailed data page for the relevant date).

appears.

In (2), if the value "badge" is true in the value of the JSON data, it becomes a background color + date character color inversion highlight. Hook this true value and

·If {badge:true}, a modal window will fall
·If it is {badge:false}, the modal window will not fall, but will stock up on the date with a hyperlink and fly to that page

I'd like to make a remodeling, but I'm stuck.

Thank you for your cooperation.
