Sending Javascript Object to PHP via Ajax

Question

I\'m learning Ajax by failure and have hit a wall:

I have an array (if it matters, the array is storing number id\'s based on what checkboxes the user checks) that i

Answer 1

Loop over the array and append encodeURIComponent('keyname[]') + '=' + encodeURIComponent(theArray[i]) + '&' to the query string each time.

furthermore, should I try using JSON?

You could, but it would mean decoding JSON at the other end instead of letting normal form handling take care of it.

And if so, how could I send a JSON object via ajax?

There is no such thing as a JSON object. JSON takes the form of a string, and you can include strings in query strings (just remember to encodeURIComponent).
