Get array from sortable jQuery serialize

Question

I have a jQuery sortable with 3 list items with the following ID's

id_1
id_2
id_3

This gets sorted by the user and serialized using the following code

var order = $("#rank").sortable('serialize');
saveResponses(order);

and printed. Which looks like this...

id[]=1&id[]=3&id[]=2

So I've got a couple of questions...

Why does the underscore get converted to "[]="
Is there a strait forward way to get an array of the original ID's? I mean without just doing a string split, and replacing the characters?

Please have a look at the official Docu: It works by default by looking at the id of each item in the format "setname_number", and it spits out a hash like "setname[]=number&setname[]=number". so far for your serialize problem — empiric

To get an array of the ids simply use the build-in function toArray — empiric

serialize converts the data into a query string. The data is formatted (converted to an array) so you can use it in a URL as a query string (GET data).

You probably want toArray:

var order = $("#rank").sortable('toArray');
