Greetings,
I'm having a problem when I try to GET a file from my server
via xmlhttp when using Mozilla. With IE I can get any type of file
fine, get/display headers fine, etc. With Mozilla, using the same
HTML/JS it always returns no data (xmlhttp.responseText is null).
When I try to get headers using Mozilla or display the http status code
I get some obscure exception in the javascript console that I've given
up on searching for an answer to ....
Error: [Exception... "Component returned failure code: 0x80040111
(NS_ERROR_NOT_AVAILABLE) [nsIXMLHttpRequest.status]" nsresult:
"0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame ::
http://myserver.com/xmlhttp.html? :: RSchange :: line 26" data: no]
Source File: http://myserver.com/xmlhttp.html?
Line: 26
I've tried coding my test app many ways based on the examples out there
and haven't been able to get it to run in Mozilla/FF yet.
If I do an alert on xmlhttp.responseText I get a blank alert pop up, if
I alert xmlhttp.responseText.length it's always zero using Mozilla.
Both alerts always work with the same HTML/JS when running in IE.
Beginning to think maybe I'm lacking something on the server side
related to Content-type being sent back that IE allows and Mozilla
doesn't(?)
Any assistance at this point would be greatly appreciated.
Thanks !
Steve
Here's a simple example that works in IE but returns null for
responseText in Mozilla when I run it ...
<HTML>
<HEAD>
<SCRIPT LANGUAGE="JAVASCRIPT" type="text/javascript">
<!--
var xmlhttp=false;
/*@cc_on @*/
/*@if (@_jscript_version >= 5)
// JScript gives us Conditional compilation, we can cope with old IE
versions.
// and security blocked creation of the objects.
try {
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (E) {
xmlhttp = false;
}
}
@end @*/
if (!xmlhttp && typeof XMLHttpRequest!='undefined') {
xmlhttp = new XMLHttpRequest();
}
function RSchange() {
if (xmlhttp.readyState==4) {
//if (xmlhttp.status == 200) {
//alert(xmlhttp.statusText); // this line chokes in Mozilla
alert(xmlhttp.responseText); //empty alert box using Moz
// }
}
}
function go() {
if (xmlhttp) {
xmlhttp.open("GET", "http://myserver.com/index.html", true);
xmlhttp.onreadystatechange=RSchange;
xmlhttp.send(null);
}
}

</script>
