Not sure what the main problem is as I'm not familiar with the tools and
don't have enough info to guess, but there are a couple of style points
that I'd make:
- You seem to have a load of jQuery code in your Express response. I'd
recommend staying well away from that approach for most applications as
it's harder to control in terms of separation of concerns, encapsulation,
caching, etc.
- Your function looks like it will return either an HTML fragment or an
HTTP redirect, which to me is a confusing combination, do you mean to
redirect the entire browser or just tell the XHR object to fetch a
different fragment from "/account"?
Also, if you're stuck it's helpful to throw a few console.log() statements
in there and make sure what's happening matches your expectations.
