@stewart Yes, but maybe not in the way you were looking for. If you're doing AJAST against example.com, the user needs to be authenticated against example.com before AJAST requests can be made. AJAST itself does not provide any means of authenticating, but does honor authentications (since it uses requests sent by the browser).

is there anyway to also use basic authentication with these commands?

Thanks for sharing this. Works pretty fine for me. Also thanks to the people who already sent bugfixes.

Ronaldo: OX.AJAST works by sending a parameter named ‘callback’ with the request. The value of ‘callback’ is the function name. OX.AJAST generates function names dynamically to avoid cluttering between simultaneously dispatching calls.

This means that for your example, you need to accept a parameter named ‘callback’ on the server side, and reply with a script that calls a function named the value of the callback parameter.

In other words, http://yourhost/resource?callback=somethingGeneratedByOxAjast should give somethingGeneratedByOxAjast(someData); in response.

Hi. Nice code. But its raising to me: callback is not defined. I’m using OX.AJAST.call(url, ‘callback’, f1, 1000, false); and my url give me callback(‘data’); I need some help. Thanks, Ronaldo.

Great little code. Is it possible to change the request headers before the call? I'd like to prevent caching. I was thinking to use cache-control no-cache as request header. Please help me how to inject that.

thanks, --IStvan

Ali: This is weird. I suspect your issue is something else. Javascript always runs in a single thread (although the XHRs themselves are run asynchronously), so synchronization is not an issue.

Hi Great Work helped me a lot with an application I am working on

however there is a bug I would like to mention

In my application I need to send like 4 to 5 requests “one after the other (onload) ” to different servlets in a “XYZ” server. and since your callbackid variable is static , this will cause some unstable response and incorrect data!

anyway … I just changed this line: var callbackid = ‘callback’ + OX.AJAST.callid;

to:

var callbackid = ‘callback’ +Math.floor(Math.random()*9999999)+ OX.AJAST.callid;

thanks for this great lib

Hi,

This library is great. however, I did manage to fix two things (1 is included above in the comments as well, but not fixed on the file linked from the article).

Line 108: OX.AJAST.Broker.callid++) should be OX.AJAST.callid++

Line 123: replace the line with the following: if (this.url.indexOf('?', 0) > -1) this.url += '&' + args.join('&'); else this.url += '?' + args.join('&'); OX.AJAST.call(this.url, this.cb, callback, this.timeout, this.jsonmode);
