Rails spinoffs - Aug 2006 - Better way to get JSON in Ajax.Updater?

So I guess there are a few ways of looking at this, but I really wish I
could access both the evaluated JSON header and the container in the
same function. I want to call an Ajax.Updater, passing an onComplete or
insertion function. In whichever function I use I want to be able to
access both the container passed to the Ajax.Updater, and the X-JSON
object that has already been eval''d *in the same function*. Am I wrong
that this isn''t (easily?) possible?

The insertion function gets the container and the transport.responseText
and the onComplete get the xhr and the X-JSON object. Why cannot one get
both? And yes, "this" is useless in both cases.

Ok, so some say the X-JSON and onComplete is only for "status"
checking
or error checking. However, it doesn''t feel right to use json and then
have to eval it myself in the insertion. I wouldn''t be using json
except
I''m working with tables and some browsers don''t like inserting
cells
into table with innerHTML.. So I''m passing either an array or a hash
through JSON and then looping through it to build each cell using DOM
and in a special case, one cell spanning the entire row.

Is there a better way to do this?

function myInsertion(container,response){
    var res = json_decode(mytext);
    if(res.form){
       //single cell spanning all columns
    }else{
       //build table cells for each item in res
    }
}
<tr id="blah>...</tr>
Ajax.Updater(''blah'',''page.php'',{insertion:myInsertion});

I''m trying to stay consistent by keeping json only in headers and html
only in the content of the response. I could eval the headers myself but
then it''d get eval''d twice, which could cause some unwanted
behavior..

Thanks,
Colin
