I taught myself programming so my knowledge is very fragmented and now I have encountered a fragment I know nothing about. Sending and receiving Date. In addition I want to do it across domains. I know about the security policies that prohibit this but have read about some solutions. I still can't make sense of it in relation to my challenge.
What I want to do:
I want to build a plugin that sends data to my server when a function is called. The function is bound to an event listener.
this plugin contains of a little html-form and some js in the back. i want to send json or simular.
my questions:
I) how do I send data to an other server?
II) how do I receive this data? I know about parsing and dom but all I did so far is handle requested data. now this data is posted to my server-app without me knowing beforehand. the data is used to update a DB. the backend is coded in JS or python. I would prefer JS for compatability reasons.
III) how can I test the cross server connection on my local machine? especially without an active internet-connection?
I don't expect a complete guide or the code i need. just the resources and where to get the knowledge-chunks I need to build this.
Thanks a bunch in advance!
