Javascript object function problem

Hi all,
I have a probelm I am trying to work around.

In the code below the id proprty is not visible in the "loadedFnc" function.

I am trying to do something asynchronously, thus am setting the onreadystatechange
property to be a function in the javascript object. However when I do this
the "this" does not see the properties of my object.

Am I being a little ambitous?

Regards
Sean

function xmlCache(pid)
{
this.id = pid;
this.load = xmlCacheLoad;
var xmlHttp = new ActiveXObject("MSXML2.XMLHTTP.3.0");
this.HTTP = xmlHttp;
}
function xmlCacheLoad()
{
this.HTTP.onreadystatechange = this.loadedFnc;
}

function loadedFnc()
{
alert(this.id);
{
//do something
}
}

Sean,

Perhaps you could try calling the loadedFnc function and passing in "this"
as a parameter like so:

this.HTTP.onreadystatechange = loadedFnc(this);

Then set your function to accept parameters such as:

function loadedFnc(obj){
alert(obj.id);
return obj.id;
}

I don't know for certain that this will work, but it should give you some
perspective on other ways to look at the problem.
