onChange and onComplete

[Nucleo]

Hi Carlos,

I'm trying to use the onChange or onComplete to trigger something after I succesfully received/posted the data. I'm currently using an easy form that wait 5 second (in PHP) and then display some text. What I want to be able to do is to be able to trigger a ajax_get() after I have used a ajax_postbyid(). Right now the onComplete or onChange is trigged before I get any data back from my request. Any clue on how I could do this?

I have updated my version of Clean to 3.1

Thanks

Hi Nucleo,

If you are using the built in onChange handler your message's onComplete will be called at the request response (readyState == 4).
To perform the ajax_get after the ajax_post, you only have to apply a onComplete handler to message used at the the ajax_post.
The sequence of your requests should be:

1 - ajax_post(msg_1)
2 - msg_1.onChange() -> calls msg_1.onComplete if assigned
3 - msg_1.onComplete -> **** you must call ajax_get(msg_2) here *****
4-  msg_2.onChange() -> calls onComplete (if assigned)
5 -  msg_2.onComplete()

Regards.

I tried to set the onComplete() of the post to an alert but the alert arrive before the loading logo disapear.

Any clues?

It does not mean that onComplete is called before onChange (it is not possible using the built in onChange handler).
There is a delay applied to progress synchronization, that's all.

function postit (url,value,method,id) {
    message = Clean.createSimpleMessage(url, null, null);
    message.method=method;
    message.value=value;
    message.id=id;
    message.silent = true;
    message.onComplete = pooling;
   
}

function pooling(status){
    Clean.doGet(message);
}

Could this work?

// Declare the global var message
var message;

function postit (url,value,method,id) {
// That is ok
message = Clean.createSimpleMessage(url, null, null);

// These lines are not required
message.method=method;
message.value=value;
message.id=id; /*the id is define by the engine not by you */

// Thats is ok
message.silent = true;
message.onComplete = pooling;

/* Here you post it. It performs some sets for you internally (message.method=POST, message.value=value). It also returns a valid message id that you can store.
*/
message.id = Clean.doPost(message, value, false);
}

/* This function will work fine only if there is only one message at message queue in each request/response. If there are other messages been sent the message.id will point to other message in futher interactions. To avoid it create a function similar to the postit that perform a HTTP GET request using the method Clean.doGet(message)*/
function pooling(status){
Clean.doGet(message);
}
