This function is used internally to convert form element values into a serialized string representation (See .serialize() for more information).

As of jQuery 1.3, the return value of a function is used instead of the function as a String.

As of jQuery 1.4, the $.param() method serializes deep objects recursively to accommodate modern scripting languages and frameworks such as PHP and Ruby on Rails. You can disable this functionality globally by setting jQuery.ajaxSettings.traditional = true;.

As of jQuery 1.8, the $.param() method no longer uses jQuery.ajaxSettings.traditional as its default setting and will default to false. For best compatibility across versions, call $.param() with an explicit value for the second argument and do not use defaults.

If the object passed is in an Array, it must be an array of objects in the format returned by .serializeArray()
