question:

I am working with jQuery sortable.
I used this tutorial:
http://www.xmech.net/programming/jquery-ui-sortable-tutorial/

Now this gives me a string like:

ID[]=2&ID[]=3&ID[]=4&ID[]=1

or even worse, when I call the id’s IDa_1, IDb_2, IDc_3, IDd_4 it gives me

IDb[]=2&IDc[]=3&IDd[]=4&IDa[]=1

I find this format maximum horrible and unuseful…
I want just pages : [“IDb_2”, “IDc_3”, “IDd_4”, “IDa_1”]
and have the order of the element in the array index.

To rectify this, I did:

var xxx =  { pages: $(this).sortable('toArray') };
alert(JSON.stringify(xxx));

This is my home controller:

public string SaveSortable(string pages)
{
    string strPages = Request.Params["pages"];

    Console.WriteLine(pages);
    return pages;
}


    public ActionResult Sortable()
    {
        return View();
    } // End Action Sortable

The problem is, both “pages” and strPages is always null…
It gets into the right controller though…
What am I doing wrong ?

This is my .cshtml:

    Layout = null;

    Simply use a JSON request:

    $('#menu-pages').sortable({
    update: function (event, ui) {
        $.ajax({
            url: '@Url.Action("SaveSortable", "Home")',
            type: 'POST',
            cache: false,
            contentType: 'application/json',
            data: JSON.stringify({ pages: $(this).sortable('toArray') }),
            success: function(result) {
                // ...
            }
        });
    }
});

    and then:

    [HttpPost]
public ActionResult SaveSortable(string[] pages)
{
    // pages will contain what you need => a list of ids
    ...
}

    For the record, here’s how the JSON request POST payload will look like:

    {"pages":["ID_2","ID_3","ID_1","ID_4"]}
