ajax & oo javascript / onreadystatechange problem

[vachacz]

hi
i'm struggling with integration of a js class aimed for ajax handling
with fireing actions from the class. here's my code sample:

function AjaxLibLoad(httpActionParam, targetLayerParam){
this.targetLayer = targetLayerParam;
this.httpAction = httpActionParam;
this.httpRequest = this.httpRequestInstance();
this.load();
};

AjaxLibLoad.prototype.load = function() {
this.httpRequest.open('get', this.httpAction);
this.httpRequest.onreadystatechange = this.action; <--here's a
problem
this.httpRequest.send(null);
};

AjaxLibLoad.prototype.action = function() {
alert('test' + this.httpRequest);
if (this.httpRequest.readyState == 4) {
if (this.httpRequest.status == 200) {

this.userAction();
} else {
alert('error');
}
} else {
return false;
}
}

AjaxLibLoad.prototype.userAction = function() {
document.getElementById(this.targetLayer).innerHTM L =
this.httpRequest.responseText;
autoInit_trees();
};

sooo what happens
ajax starts well, but alert('test' + this.httpRequest); gives me 'test
[HttpXML...]' only for the first time (action is fired 4 times)

so what for is oo ajax ?? i'm trying to write application that lunch
many ajax instances at the same time, so each one have to run on it's
own httpRequest object to avoid freezing (tha happend when i used one
global instance of httpRequest)

it's interesting issue. it would be great to solve it
thank for Your help
