This is what I get without your code: index1.html:1 XMLHttpRequest cannot load http://192.168.1.122:81/servos.rpy?value=70P. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://192.168.1.122:9000' is therefore not allowed access. jquery.min.js:4 XHR failed loading: GET " http://192.168.1.122:81/servos.rpy?value=70P";.
