SAFARI 2.0.4 and version 1.5.1_rc3 prototype using JSON

i''ve been trying my hardest to work out why the following
doesn''t work
on safari but works well with FF and the evil IE..

new Ajax.Request(''/include/dynamic.php?Login'', {
 method: ''get'',
  requestHeaders: {Accept: ''application/json''},
  evalScripts: true,
  onSuccess: function(transport, json){
     if (json.length>0 && json.length!=undefined) {
	for (var i=0; i<json.length; i++) {
	   objHolder.push([json[i].name, json[i].node, json[i].replacement])
	}
      } else if (json.length == undefined && json.name != undefined) {
	objHolder.push([json.name, json.node, json.replacement])
      }
   }
});

which calls the dynamic.php for its login scripts that returns:

HTTP/1.0 200 OK
Connection: close
X-Powered-By: PHP/5.2.1
Content-type: application/json
X-JSON:
[{"name":"recover","node":"login","replacement":"<form

under Firefox/ie it loads these two functions but not under safari,
and when i try to output json with alert(json) i get nothing, can
anyone lend me an extra set of eyes on this one please? my guess is on
the function(transport, json){..} side of it since none of the docs
reference calling it like this but its the only way it works under IE/
FF

Re: SAFARI 2.0.4 and version 1.5.1_rc3 prototype using JSON

You''d be safer outputting your JSON in the responseText rather than in
a header.

Tobie, my new best friend!

worked like a charm in safari and just took one line in the js
function:

new Ajax.Request(''/include/dynamic.php?Login'', {
  method: ''get'',
  requestHeaders: {Accept: ''application/json''},
  evalScripts: true,
  onSuccess: function(transport, json){
    //Tobie rocks for this next line for safari support
    json = json || transport.responseText.evalJSON();
    if (json.length>0 && json.length!=undefined) {
      for (var i=0; i<json.length; i++) {
        objHolder.push([json[i].name, json[i].node,
json[i].replacement])
      }
    } else if (json.length == undefined && json.name != undefined) {
      objHolder.push([json.name, json.node, json.replacement])
    }
  }
});

also i printed the content instead of including it in the header:
//php class function
private function output($array) {
  $output = json_encode( $array );
  header(''Content-type: application/json'');
  print($output);
}

Same but different.

While some cases require putting the JSON in the body instead of headers since
browsers do limit the sizes of headers they accept (anyone know where these
limits are documented for each browser?), I will point out that you
don''t have
to. In your case safari has an issue where it won''t process the headers
if
there''s no body content in the response. So simply adding an empty
newline char
or something similar would have made your original problem work.
