Why doesn't this javascript ajax function return a value?

Asked by CoastalData in JavaScript, Dynamic HTML (DHTML)

Tags: ajax

Hello Experts,

I have this relatively simple function which sort of works, but won't return a value for me to then assign to the innerHTML of a div:

/***********************************************
* Basic Ajax Routine- © Dynamic Drive DHTML code library (www.dynamicdrive.com)

***********************************************/
function processGetPost(){
      var myajax=ajaxpack.ajaxobj
      var myfiletype=ajaxpack.filetype
      var myresponse
      if (myajax.readyState == 4){ //if request of file completed
            if (myajax.status==200 || window.location.href.indexOf("http")==-1){ //if request was successful or running script locally
                  if (myfiletype=="txt")
                        // works:
                        alert(myajax.responseText);
                        // returns undefined:
                        return(myajax.responseText);
                  else
                        return(myajax.responseXML);
            }
      }
}

I can see that the function works because I can use the alert to see the response, but for some unknown reason, I can't return that value to another function which then assigns the responseText to the innerHTML of a div on the page.

Could somebody please take a look and see if you can spot my error?

Thanks in advance!
