AJAX Error 0x80040111 (NS_ERROR_NOT_AVAILABLE)

[kamo]

 
 Hi!

 > I'm having some problems to debug some AJAX oriented code that follows:

       
function sendAjaxRequest(formIndex, outputElement, flagElement){

var Form     = document.forms[formIndex];
var requestString  = getRequestString(Form);
var XMLHttp        = makeXMLHttpObject();
                       
                        // Output the status element
                        build_loading_flag(flagElement);

                        XMLHttp.open("post", Form.action, true);
                        XMLHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8");
                       
                        XMLHttp.onreadystatechange =
                                function (){
                                        if(XMLHttp.readyState == 4){
                                                // This is resultant response form the server
                                                showResults(XMLHttp.responseText, outputElement);
                                                destroy_loading_flag(flagElement);
                                                // Resets the form content
                                                //document.forms[formIndex].reset();
                                        }
                                        else{
                                        if (XMLHttp.statusText != "OK"){
                                                alert("An error has occurred. Status: " + XMLHttp.statusText);
                                                destroy_loading_flag(flagElement);
                                        }
                                        else {
                                                destroy_loading_flag(flagElement);
                                        }
                                     }
                                };
                                // This would be set to null in case of a GET request
                                XMLHttp.send(requestString);
                        }

 Every time I invoke this function Firefox error console throws the following message at the line that calls the statusText attribute:

[Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.statusText]"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"

Can someone help me out on this one. I'm not proefficient in this matters.
 -- Thanks in advance.

Your not in the correct state to read that variable.

Check out http://svn.bluga.net/HTML_AJAX/trunk/js/HttpClient.js for an
example on how it should be done.

_readyStateChangeCallback is the method that checks the status

 > Hi!

 Thank you for the reply. I'm not sure how to adapt the sample code you sent me to my case, due to my dreadful Javascript coding abilities. Although I understand the inner logic I don't recognize some other underlying layers of functioning. If I sent you my AJAX Javascript code could you kindly try to adapt and comment it.

The thing is that at this moment I am implementing some GIS functions on PHP/PostgreSQL/PostGIS that are rather complex and time demanding. Also if you agree I would be very proud to make a reference to your efforts on my MSc or other related works.

 -- Best regards

Hey,

I dont really have time to help I would recommend using a library to
handle your AJAX needs either HTML_AJAX or something else.
