I have a webserver, and a webpage can show me the current temperature values from EMX. The temperature values are loaded into a data.txt file for my web-server to serve. via AJAX-xmlhttprequest or jquery method this data.txt file could be updated every 5 seconds, then, corresponding with the update of my temperature-output web page.(see picture 1). the yellow field show me the current temperature values, the values are refreshed every 5 seconds.
Beside reading the parameter from EMX to webpage, I want to write parameter from webpage to EMX too. I want to define a parameter field(parameter table) on this webpage (see picture 1), if I click or double click the value of parameter, I can change the value of the parameter and the changed value can be transformed to EMX. Can you give me some suggestion, how can I realize my thinking?
