I've decided to being a slightly ambitious project. Like Drupal
before, I'm trying to create a CMS using JQuery for some of the client
side functionality. At the moment I'm just trying to write the
underlying RPC calls using JSON-RPC (v1.1) (Yes I know its still a
working draft, but I'm trying to get ahead of the game).
I have a weird issue occuring when I make the AJAX call. Using
Firefox, it works as one would expect. But using IE 6, the same call
fails. Chucking in some debugging alerts, and things in, I see that IE
is actually returning a readyState of 4, and a status code of 200...
Yet the error event is still being triggered. When I run a packet
sniffer on the web server, I see the session happen correctly, with
the status code of 200. Any one got any ideas of what I'm missing?
The source looks like this...
jQuery.extend({
jsonrpcSettings: {
type: "POST",
timeout: 5000,
url: null,
data: null,
callback: function() {}
},
jsonrpcCall: function( s ) {
s = jQuery.extend({}, jQuery.jsonrpcSettings, s);
if (( !s.url || s.url===null ) || ( !s.data || s.data===null )) {
alert("URL or data is missing!");
return false;
}
if ( s.callback !== null && !jQuery.isFunction(s.callback))
{ return false; }
/*
try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
} catch (e) {}
*/
jQuery.ajax({
url:
s.url,
type: s.type,
contentType: "application/json",
data : s.data,
dataType: "json",
beforeSend: function(xhr) {
xhr.setRequestHeader("Accept",
"application/json");
},
global: false,
timeout: s.timeout,
success: function (data) { alert("It worked!!"); },
error: function (xhr, status, expobj) { alert("It DIED!!
Horribly"); },
complete: function(xhr, status) {
alert("Complete [" + status + "]");
alert("Status code [" + xhr.status + "]");
alert("ReadyState is [" + xhr.readyState + "]");
for(elem in xhr) { alert( elem + " = " + xhr[elem]); }
}
});
return true;
}
});
And the call for the function is...
$(document).ready(function(){
var srvCall = {
url: "http://webserver:8888/development/
services.cgi",
data: {
"version" : "1.1",
"method" : "echo",
"params" : { echo: "hello echo" }
},
callback: function() { alert("Done?"); }
};
try{
$("#JSONRPCTest").click( function()
{ $.jsonrpcCall(srvCall); });
}
catch(e) {
}
});
JSONRPCTest is the ID for a div object.
