10,323 PointsWhen is it necessary to .serialize() in an AJAX post request; ?
When using jQuery to make AJAX POST requests, Is it always necessary to format the data with .serialize() before sending up to the server?
Is it always necessary when sending data from HTML forms?
If yes, what kind of AJAX post requests would not need the .serialize() method?

"The serialize() method creates a URL encoded text string by serializing form values. You can select one or more form elements (like input and/or text area), or the form element itself. The serialized values can be used in the URL query string when making an AJAX request."
So you would use it when you are selecting form elements (like check boxes, radio buttons, input strings) and you need to put them together to be part of a query on a URL.

10,323 PointsSo do GET and POST data collected from forms elements both need to be formatted with serialize before being send to the server?
Only GET requests send data up on the URL query string. correct?
