I am using Express.js in my project. When I submit a form, a function is executed and what I would like is that at the end of the function, it changes the page from index to results.

io.on('connection', function(socket){
  socket.on('query', function(qCity,qState,qLowPrice,qHighPrice, req, res){

I want it to redirect here:

  }); // end of socket.on query function
}); // end of io.on

I've read on some posts about using middleware but still not sure it's exactly what I want.

use res.redirect

io.on('connection', function(socket){
    socket.on('query', function(qCity,qState,qLowPrice,qHighPrice, req, res){
    res.redirect('http://yourdomain.com/result')

    });

Ahh 30 seconds to slow: )
This is what you want. You can learn more by reading the Express.js API documentation found at: expressjs.com/en/4x/api.html#res
When I try this it errors with res.redirect('/results.ejs')TypeError: Cannot read property 'redirect' of undefined
@sewersama do you have a page called result ?
Yes I do, I think the error is related to res in someway because if I'm reading it correctly it thinks res is undefined inside of the function so maybe i have to make it global somehow or something.

You should just be able to use redirect in express like this:

res.redirect('your/path.html');

For some reason it errors with res.redirect('/results.ejs')TypeError: Cannot read property 'redirect' of undefined. Any idea about this?
