What is it?

$.serializeObject is a variant of existing $.serialize method which, instead of encoding form elements to string, converts form elements to a valid JSON object which can be used in your JavaScript application.

Why?

Whilst it isn't necessary in most cases, and by that I mean 99.99% kind of most, there are times when we manipulate form data on client side. Personally I find JSON much easier to work with than DOM or string manipulation.

How do I use it?

Simply include the jQuery.serializeObject.js along with any jQuery instance and use it like $.serialize.

If you have a form like the following:

<formid="minutes"><inputtype="text" name="subject"><inputtype="text" name="minute-taker"><!-- ... --><inputtype="checkbox" name="attendees" value="David" checked="checked"><inputtype="checkbox" name="attendees" value="Daniel" checked="checked"><inputtype="checkbox" name="attendees" value="Darwin" checked="checked"></form>

and wish to convert them to a JSON object:

varminutes=$('form#minutes').serializeObject();

will return:

{
"subject": "",
"minute-taker": "",
"attendees": [
"David",
"Daniel",
"Darwin"
]
}
