Re: [WEB400] AJAX troubles...






Try to change what triggers the getToolRoute function to a non-input 
field.
For example, change it to:
<a href="#" onclick="getToolRoute()">Get Tool Route</a>

For some reason some browsers have trouble with this. Let me know if this
works... if not I might have some other ideas, but try this first. What
browser are you using by the way?

All:

I'm trying to dynamically load a table using AJAX with RPG-CGIDEV2 as 
the
back-end...and I'm getting a weird error that I don't really 
understand...

I have 3 fields on the web page that I'd like the user to fill out
(tproject, lampcode, tooltype)...once all 3 have been filled out, I'd 
like
to use AJAX to populate the table based on the data entered...2 of the
fields are input boxes with appropriate onBlur events to call 
getToolRoute
and the 3rd is a dropdown box with an onChange event to call
getToolRoute...here's my AJAX...

function getXmlHttpRequestObject() {
if (window.XMLHttpRequest) {
   return new XMLHttpRequest();
} else if(window.ActiveXObject) {
   return new ActiveXObject("Microsoft.XMLHTTP");
} else {
   alert("Your browser doesn't support AJAX!");
}
}

var request = getXmlHttpRequestObject();

function getToolRoute() {
if (document.getElementById('tproject').value != "" &&
document.getElementById('lampcode').value != "" &&
document.getElementById('tooltype').value != "") {
   if (request.readyState == 4 || request.readyState == 0) {
     var proj = escape(document.getElementById('tproject').value);
     var lamp = escape(document.getElementById('lampcode').value);
     var ttyp = escape(document.getElementById('tooltype').value);
     var type = escape(document.getElementById('type').value);
     for (var l = 1; l < 99; l++) {
       if ((type == 'T' && (l < 6 || l > 8 || l < 10)) ||
          (type == 'Y' && (l < 2))) {
         for (var s = 1; s <= 6; s++) {
           if (request) {
             request.open('GET', '/cgi-test/erqajxtrm?proj=' + proj +
'&lamp=' + lamp + '&ttyp=' + ttyp + '&type=' + type + '&lvl=' + l +
'&stp=' + s, true);
             request.onreadystatechange = handleRoute(l,s);
             request.send(null);
           }
         }
       }
     }
   }
   //request.open('GET', '/cgi-test/erqajxtrm?proj=' + proj + '&lamp=' +
lamp + '&ttyp=' + ttyp + '&type=' + type, true);
   //request.onreadystatechange = handleRoute;
   //request.send(null);
}
}

function handleRoute() {
var x = handleRoute.arguments;
var l = x[0];
var s = x[1];
if (request.readyState == 4) {
   var step = document.getElementById('lvl' + l + 'step' + s);
   step.innerHTML = '';
   //var msgs = document.getElementById('messages');
   var str = request.responseText.split("\n");
   if (str != "") {
     step.innerHTML = str;
   }
} else {
   alert(request.statusText);
}
}

and my html as follows:

/$routedetail
<tr id="level/%level%/" onMouseOver="this.bgColor='#cddfed';" 
onMouseOut=
"this.bgColor='#FFFFFF';">
<td align="center">/%level%/<input type="hidden" name="lvltype" id=
"lvltype" value="/%lvltype%/"></td>
<td align="center"><div id="lvl/%level%/step1">/%step1%/</div></td>
<td align="center"><div id="lvl/%level%/step2">/%step2%/</div></td>
<td align="center"><div id="lvl/%level%/step3">/%step3%/</div></td>
<td align="center"><div id="lvl/%level%/step4">/%step4%/</div></td>
<td align="center"><div id="lvl/%level%/step5">/%step5%/</div></td>
<td align="center"><div id="lvl/%level%/step6">/%step6%/</div></td>
</tr>

here's the error I'm getting:

uncaught exception: [Exception... "Component returned failure code:
