Rails spinoffs - Apr 2006 - Problems using Sortable with an onUpdate callback

Hi all:

I''m using sortable (very cool stuff!) on a series of divs with an
onUpdate callback.  Everything appears to work alright until I try to
pass a parameter to my callback function like this:

Sortable.create( ''page_33'',
  {
     tag: ''div'',
     onUpdate: updateOrder(''page_33'')
  }
);

When I pass that parameter to the updateOrder function (as opposed to
just using the updateOrder function without a call back) I get the
following error in my JavaScript console:

"Options has no properties (dragdrop.js line 870)"


My call back function looks like this:

function updateOrder(elementid)
{
    var options = {
        method : ''post'',
        parameters : Sortable.serialize(elementid)
    };

    new Ajax.Request(''test.php'', options);
}

I would greatly appreciate if anyone has any suggestions as to how I
might successfully pass a parameter to my updateOrder function without
causing the Scriptaculous stuff to crash and burn.

I''m willing to bet that this is all just because of my general lack of
experience with JavaScript but I''m hoping I might be wrong (just this
once).


Thank you in advance,

Matt

This calls updateOrder at once and assigns the result to onUpdate. ()
means "execute the function".

Use  onUpdate: updateOrder.bind(this, ''page_33'')

For more details search the mailing list archive for the thread
"Prototype Ajax - How to pass my own params to onComplete ?" from this
week.
