Passing nested arrays to asp.net mvc using jQuery's $.ajax

Question

I am trying to pass a nested array to an asp.net mvc controller like this:

var subgroups = [];
subgroups [0] = [[\"A\", \"Y\"],
                 [\"B\", \"Y\"],
         


        

Answer 1

in file "code.jquery.com/jquery-1.4.2.js" in line 5290:

buildParams( prefix + "[" + ( typeof v === "object" jQuery.isArray(v) ? i : "" ) + "]", v );

I change for this code:

buildParams(prefix + (typeof v === "object" jQuery.isArray(v) ? "[" + i + "]" : ""), v);

and the result was good. I could not test on many more cases.

I create a ticket in jQuery.com to see if this is a bug: Ticket #6900 (new bug)

but in:

public ContentResult Action(List<string[][]> subgroups) {

for this modification, you have to use this code:

public ContentResult Action(List<string[]> subgroups) {

Answer 2

In case anyone else stumbles on this question like I did but doesn't like the idea of modifying jQuery to work with your particular server software, I ended up using JSON.stringify() to pass a JSON string of nested arrays to the server, and then decoding that JSON string on the server.
