Is this code running in a browser or in node? If it's running in a browser,
then I don't see how it can work, because you're accessing filesystem paths
("C:/Program Files/...") which you won't have permission to do. And if it's
running in node, then I don't see how it can work, because you're accessing the
nonexistent alert function and localStorage object; try using console.log
instead of alert, and using normal variables instead of localStorage.
Either way, there are a lot of things in this code that look wrong.
I'm not familiar with jsftp, but I'm confused by the fact that you're passing
the username and password in the options object when calling the jsftp
constructor, but then are passing the same username and password to the
ftp.auth function. Seems odd that you would have to provide the credentials
twice. Are you sure that's how jsftp is meant to be used?
Your code doesn't look very asynchronous to me. You're calling ftp.auth, and
not waiting for the result of that operation before calling ftp.put. Possibly
the server hasn't authenticated you yet by the time you've started the put. For
starters, try putting the ftp.put invocation inside the callback in the
ftp.auth invocation, after you've ensured no error occurs. You also need a way
of informing whatever code called uploadHours() when it is complete, and if an
error occurred. Usually this is done by using a callback, i.e. you would define
your function as "function uploadHours(callback)" and it would call
"callback()" when it's done, or "callback(err)" if an error occurred (assuming
"err" is an error object describing the error).
Note also that you have a typo in your error handling. In your ftp.put
invocation you've named the parameter "hadErr" but are then accessing the
undefined variable "hadError". Looks like the jsftp project's documentation
uses these two different variable names in different examples, which is
confusing. You might send them a pull request to always use the same error
variable name for consistency.
