file upload using krajee plugin and backendless Js api

Hi
I found a jquery and bootstrap file upload plugin which has a file preview, progress bar and can be used using ajax based uploads. you can see demo here:
http://plugins.krajee.com/file-input-ajax-demo/1
As you see for server upload action there is a uploadUrl in script .How can I use backendless Js library’s restUrl which file upload api uses that to run a server side script.

Hello,
