AJAX login

JavaScript
1

I’m looking to create a log in with just ajax, i.e. so that the page doesn’t need to be refreshed for log in…

…of course this would need to contact the database - which I can do via a XMLHttpRequest but I cannot seem to figure out how to get info back - i.e. if the login was successful (was the username and password found) … can anyone help me as to how I would do that <<

> with thanks

jQuery:

Creating such a system involves posting the user input to the server side then returning the response back to the client.

Take a look at these also (post #5 and #7):

shall I assume that no one in this forum knows?

You should not rely solely of AJAX as the end user may have javascript disabled. Are you still running the login attempts via whatever server-side language your using. As a rule of thumb you should never trust any user submitted data, you should escape and validate it in whatever server-side language your using.
