According to your console output:
XMLHttpRequest cannot load file:///C:/Users/hamma/Desktop/rao.html. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.

and for security reasons you can’t run AJAX requests like that.
You need to setup a server and run the page through that to send requests.
