Jquery tableDnD - How to create an ajax with ID and position ondrop?

My code:

  <script type="text/javascript">
$(document).ready(function() {
    // Initialise the table
    $('#admintabel').tableDnD({
        onDrop: function(table, row) {

        }
    });

});
</script>

How do I create an ajax call to example /sort with the parameters position and ID in a has like this: [position, ID] onDrop? And how should my table be like.

Update:

I am trying to create an array like:

BREDBANDS[id]   1
BREDBANDS[id]   2
BREDBANDS[id]   3

My current test data:

data: {
                  BREDBANDS: [1, 2, 3]                  },

And it is posting this:

BREDBANDS[] 1
BREDBANDS[] 2
BREDBANDS[] 3

Which is giving a 500 error.

My Rails action which the data is posted to:

  def sort
  params[:bredbands].each_with开发者_如何学C_index do |id, index|
    Bredband.update_all(['position=?', index+1], ['id=?', id])
  end
  render :nothing => true
end

It's hard to understand what you're actually asking but making an Ajax request should be done in any of these two ways:

$.ajax({
    type: "GET",
    url: "/sort?" + $.tableDnD.serialize(),
    success: function(){
        ...
    }
});

or

$.ajax({
    type: "POST",
    url: "/sort",
    data: $("tr", "$admintabel").map(function(){
        return this.id;
    }),
    success: function(){
        ...
    }
});

But as it seems you need to provide IDs to your TR elements. Then you should be able to call this:

$.tableDnD.serialize();

which will serialize data of the table and it's row IDs.
