Digital Ether, you saved me from pulling my hair out.
I was trying to work on my website at a different location and Firefox would not properly handle my http requests, even though it works fine at home.
Forgetting that I had Firebug installed at home I couldn't figure out why I could not find the GET and POST data I was looking for.
After reading your post I installed Firebug to see if I could get to the information and solve the problem, but just installing Firebug
fixed the problem!
While this is great for me I am concerned about the users of my web app.
Here is the HTTP request object I got from somewhere, I can't remember where. (I am new at this AJAX stuff)
function HttpClient() { } // HTTPCLIENT CLASS
HttpClient.prototype = {
// type GET,POST passed to open
requestType:'GET',
// when set to true, async calls are made
isAsync:true,
// where an XMLHttpRequest instance is stored
xmlhttp:false,
// what is called when a successful async call is made
callback:false,
// what is called when send is called on XMLHttpRequest
// set your own function to onSend to have a custom loading
// effect
onSend:function()
{
//document.getElementById('HttpClientStatus').style.display = 'block';
},
// what is called when readyState 4 is reached, this is
// called before your callback
onload:function()
{
//document.getElementById('HttpClientStatus').style.display = 'none';
},
// what is called when an http error happens
onError:function(error)
{
alert(error);
},
// method to initialize an xmlhttpclient
init:function()
{
try
{
// Mozilla / Safari
this.xmlhttp = new XMLHttpRequest();
}
catch (e)
{
// IE
var XMLHTTP_IDS = new Array('MSXML2.XMLHTTP.5.0',
'MSXML2.XMLHTTP.4.0',
'MSXML2.XMLHTTP.3.0',
'MSXML2.XMLHTTP',
'Microsoft.XMLHTTP');
var success = false;
for (var i=0;i < XMLHTTP_IDS.length && !success; i++)
{
try
{
this.xmlhttp = new ActiveXObject
(XMLHTTP_IDS[i]);
success = true;
}
catch (e)
{}
}
if (!success)
{
this.onError('Unable to create XMLHttpRequest.');
}
}
},
// method to make a page request
// @param string url The page to make the request to
// @param string payload What you're sending if this is a POST
// request
makeRequest: function(url,payload)
{
if (!this.xmlhttp)
{
this.init();
}
this.xmlhttp.open(this.requestType,url,this.isAsync);
// set onreadystatechange here since it will be reset after a
//completed call in Mozilla
var self = this;
this.xmlhttp.onreadystatechange = function()
{
self._readyStateChangeCallback();
}
if (this.requestType == "POST")
{
this.xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
this.xmlhttp.setRequestHeader("Content-length", payload.length);
this.xmlhttp.setRequestHeader("Connection", "close");
}
this.xmlhttp.send(payload);
if (!this.isAsync)
{
return this.xmlhttp.responseXML;
}
},
// internal method used to handle ready state changes
_readyStateChangeCallback:function()
{
switch(this.xmlhttp.readyState)
{
case 2:
this.onSend();
break;
case 4:
this.onload();
if (this.xmlhttp.status == 200)
{
this.callback(this.xmlhttp.responseXML);
}
else
{
this.onError('HTTP Error Making Request: ' + '[' + this.xmlhttp.status + ']' + ' ' + this.xmlhttp.statusText);
}
break;
}
}
}
And the offending call:
function set_dynamic_globals()
{
client.requestType = "GET";
client.callback = function(XMLresult)
{
if (XMLresult.getElementsByTagName("status"))
{
http_status = XMLresult.getElementsByTagName("status")[0].childNodes[0].nodeValue;
}else{
http_status = "FAILED";
return;
}
if (http_status == "SUCCESS"){
// bunch of code that reads the values from the XML doc
}
}
client.makeRequest(url,null);
return;
}
This call does not actually send anything, the target is a PHP created XML doc that contains values read from a database.
Do you see anything wrong with this that would cause Firefox (without Firebug) to fail while IE 6 and IE 7 worked fine?
Much thanks!!
