Thanks @Manish Mittal for your response.

I had tried using the first link (stackexchange.com). It increments and decrements the quantity. But i need to update the cart automatically once i clicks the +/- button. If i clicks the +/- button, the page has to be load and the cart value needs to be changed. I am stuck on that updation. Kindly help if you know the solution for that.

Hi @Manish Mittal 

Refused to execute script from 'http://127.0.0.1/magento/pub/static/frontend/Samplestore/theme/en_US/custom.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.
require.js:141 Uncaught Error: Script error for: custom

I have got these errors in the console.

Can you please share the details of Network tab (Chrome debug toolbar) as well?

It seems request should return content in some format (like JSON) & its returning in another format (Might be due to 404 status OR something else).

It seems that you have placed your js file on the wrong location.

Currently, your js file location is

http://127.0.0.1/magento/app/design/frontend/Samplestore/theme/custom.js

But it must be as given below

http://127.0.0.1/magento/app/design/frontend/Samplestore/theme/web/js/custom.js
