    Question Help! Sending Request, yet no readystatechange..

    So I have a problem that I can't seem to fix, no matter what I do.
    The code below SHOULD create a 'slideObj' object and then use it to get some information from a php file called queryslides.php.

    However, the code seems to only get to sending the request; it never RECIEVES any data back.
    The function outlined in "this.request.onreadystatechange = this.infoReturn;" which is infoReturn() never gets called up. Everything before it works great, but it stops after the onreadystatechange part.

    I have my code below, with comments inserted for ease of reading.
    function slideObj() {
    this.request = null;         //get a request object
       try {
         this.request = new XMLHttpRequest();
       } catch (trymicrosoft) {
         try {
           this.request = new ActiveXObject("Msxml2.XMLHTTP");
         } catch (othermicrosoft) {
           try {
             this.request = new ActiveXObject("Microsoft.XMLHTTP");
           } catch (failed) {
             this.request = null;
        if (this.request === null) {
         alert("Error creating request object!");  
       function sendGetServer() {
           this.request.open("GET", "queryslides.php", true); 
    //queryslides.php is a php file with only one active line
    //echo "1|r|d~3|s|f";
         this.request.onreadystatechange = this.infoReturn;
         alert('Message Requested');  
    //Every 'alert' is activated, except for those in the two functions below 
       function infoReturn() {
         if (this.request.readyState == 4) {
           /* Get the response from the server */
           var info = this.request.responseText;
        alert('Info recieved');
           /* Format Data */
    //The next function works by itself, so this isn't really a problem
    // Except for the alert line, you can just pretend the goOn() doesn't do anything.
            function goOn(inf) {
    this.goOn = goOn;
    this.infoReturn = infoReturn;
    this.sendGetServer = sendGetServer;
    var hey = new slideObj();
    What can I do?
    I have a link to the page here: http://hiroshifukada.no-ip.biz/sense/TEST.html~ (Note: The linked file is not EXACTLY the same as the example I gave. I'll update the file to what I show here as soon as I can.)

    Thumbs down Oops!

    Sorry about this, I accidentally set the prefix to 'Resolved' even though I didn't mean too.
    Can we delete this 'accidentally resolved' thread?
