Rails spinoffs - Mar 2007 - Ajax.Request don't work any more when update prototype from 1.4 to 1.5

Hello,

I was wokring on an admin programme using HTML and Ajax and Prototyp.

When I update Prototype from 1.4 to 1.5 nothing works anymore.
No request leave my browser (no log of of HTTPRequest in the Firebug
consol) no error message nothing ! I got crasy ...

Event sample code from Prototype doc doesn''t work.

The code sample bellow work fine with version 1.4 but not with 1.5.

var handlerFunc = function(t) {
	 alert( t.responseText );
}

var errFunc = function(t) {
    alert(''Error '' + t.status + '' -- '' +
t.statusText);
}

new Ajax.Request(''./remote.php'',
{parameters:''action=listBlob'',
onSuccess:handlerFunc, onFailure:errFunc});

The remote.php is working fine I test it appart.

Did I miss something ..

Im'' working on a Windows XP SP2 computer with Firefox 2.0.0.2. and
XAMPP Apache/MySQL/PHP.

Thanks

Constant

Hey there,

Do you by any change use json.js or another library (e.g. Rico) that 
extends Object.prototype?  If so, that''s your issue, as
1.5.0''s version
of header management for AJAX requests uses a for...in loop, which will 
stumble on Object.prototype extensions.

Which is why extending Object.prototype is, er, *evil* :-)

Search this group''s archives for many possible solutions, until 1.5.1 
comes out :-)

I''ve got a similar problem, when after upgrading to 1.5.0 from 1.4.0 a
synchronous request stopped working:

 var desc     = new Array();
 desc.Load = function ()
 {
    var myAjax = new Ajax.Request(''description.txt'',
  	 	              { method: ''get'',
                                asynchronous: false} );

    var values=myAjax.transport.responseText.split(''|'');
    while (values.length) this.push(values.shift());
    myAjax=null;
 }

It stumbles on the next line after the new Ajax.Request, saying that
data isn''t yet available. Couldn''t find a solution. Using
asynchronous
requests doesn''t make sense, since it''s an initialisation
function and
a user has to wait anyway. Any ideas? Thanks!

In addition, I am not using json.js or pico, however add couple of
things via prototype to standard JS objects, like:

String.prototype.trim = function () {return this.replace(/^\s*|\s*
$/,"");}

Removing them doesn''t help.

Hey Vlad,

It''s not specific prototypes you have to be worried about,
it''s
Object.prototype, specifically.  Either in your own code, or in the code 
of libraries you use.

Christophe,

thank you. I am not using Object.prototype. However after some testing
things finally cleared up:

After switching to 1.5.0 the script stopped working within IE 7.0 when
loaded from HDD (even after I «ok» the IE security messsage). Once I
uploaded the script to www it started working just fine.

Some of the 1.5.0 changes apparentely broke Ajax.Request behaviour in
the offline mode.

Vlad
