Hi Shog, Thanks for the reply. I am not sure if the way you suggested would work. I am using function MyClass(){....} type declaration to declare my class. So, if i want to assign the readystatechange for a particular object, i think, i'll have to use something like this.xmlHttpObj.readystatechange = this.MonitorStateChange; Can you please tell me more about the way you have written above. Any reference where i can learn more about it. Here's my code... I'll highly appreciate it if you can give me some pointers. Thanks in advance.
function AJAXFramework(OnCompFunc) //The AJAXFramework class
{
//Four methods for the 4 possible states
this.OnLoading = null; // 1
this.OnLoaded = null; // 2
this.OnInteractive = null; // 3
this.OnCompleted = OnCompFunc; // 4
this.SendRequest = SendRequest;
this.xmlHttp = null;//GetXmlHttpObject(); // To be initialized when SendRequest() is called
//other member functions
this.SendRequest = SendRequest;
this.MonitorStateChange = MonitorStateChange;
alert("OnCompleted = " + this.OnCompleted);
alert(this.xmlHttp);
function SendRequest(strURL, strType, strParams)
{
//strURL : the url to be contacted
//strType : Request type. Can have only one of the following:
// "GET", "POST"
//strParams : if request type is POST, then parameters that
// should be sent.
//abort any ongoing request
if (this.xmlHttp != null && this.xmlHttp.readyState != 0 && this.xmlHttp.readyState != 4)
{
this.xmlHttp.abort();
}
//Get the XMLHttp object
xmlHttp = GetXmlHttpObject();
//Set the event listener
xmlHttp.onreadystatechange = this.MonitorStateChange;
//alert("calling...");
//this.MonitorStateChange();
if (strURL.length > 0)
{
if(strType == "GET")
{
xmlHttp.open("GET", strURL , true);
xmlHttp.send(null);
}
else
if(strType == "POST")
{
xmlHttp.open("POST", strURL, true);
xmlHttp.send(strParams);
}
else
{
alert("Request type has not been specified properly.\nRequest types can be GET or POST only.");
}
}
}
function MonitorStateChange()
{
//alert(AJAXFramework.OnCompleted);
//alert(this.readyState);
alert("OnCompleted = " + this.OnCompleted);
//alert(arguments.length);
if(this.xmlHttp.readyState == 1)
{
if(this.OnLoading != null)
{
OnLoading();
}
return;
}
if(this.xmlHttp.readyState == 2)
