title: node.js executing server side function from client side
body: <p>I have the server.js file on server side and the index.html on client side. I need to call a function from the server side through maybe a button or something on the index.html and get a feedbak on the index.html that the function was executed.</p>
  
  <p>In the future I would also like to pass over a variable to the server side from client side.</p>
  
  <p>I'm rather new to node.js. Hopefully someone can help me on this. </p>
