Solr client in JavaScript

Thu, 01 Oct 2020 04:14:55 -0700 

This is my javascript code ,from where I am calling solr ,which has a
loaded nutch core (index).
My java script client ( runs on TOMCAT server) and Solr
server are on the same machine (10.21.6.100) . May be due to cross
domain references issues OR something is missing I don't know.
I expected Response from Solr server (search result) as raw JASON
object. Kindly help me fix it.Thanks in advance .
