How to call servlets using AJS in JIRA plugin?

[imamudin naseem]

I know a way to call REST APIs using AJS. 

I want to call POST of servlet using AJS. Via given docs, I could only  find a way to call GET of servlets via hitting http://localhost:2990/jira/plugins/servlet/{servletURL}  in browser. Is there a way to call same url with POST method using AJS?

Try with 

AJS.$.post()
