Question

I have an express server that has a button that issues a POST which activates a function in my node.js server.

Instead of sending a post, I would like to do something kind of like AJAX because I don’t want a new page to load. If I use a Javascript button, is there a way I can directly call a function defined in the node.js server instead of having to send a post?

I noticed that JSON values can be passed into the .ejs webpage when it’s rendered, but I haven’t been able to get it to work for functions.

You can use Socket.io to emit an event from the browser, and than listen for that event on the server to act on it.

Socket.io works flawlessly with express http://socket.io/#how-to-use
