XMLHttpRequest won't work in Firefox 1

[roblasch]

Can anyone explain why this works in ie, but not firefox?
From editing this code and substituting alert statements, it seems that the readystate never gets past 1, but I don't see why.

function objConstruct(url,obj){
this.url=url;
this.lyr=document.getElementById(obj);
this.conn=createRequest(this);
}

function createRequest2(obj){
try {
obj.conn = new XMLHttpRequest();
}catch(trymicrosoft){
try{
obj.conn = new ActiveXObject("Msxml2.XMLHTTP");
}catch (othermicrosoft) {
try{
obj.conn = new ActiveXObject("Microsoft.XMLHTTP");
}catch (failed) {
obj.conn = false;
}
}
}
if (!obj.conn){
alert("Error initializing XMLHttpRequest!");
}else{
obj.conn.open("GET", obj.url, true);
obj.conn.onreadystatechange = function(){
if (obj.conn.readyState == 4){
if (obj.conn.status == 200){
obj.lyr.innerHTML+=obj.conn.responseText;
obj.lyr.style.width="98%";
obj.lyr.style.position="relative";
}
}
}
obj.conn.send(null);
}
}
var xmlhttp=new objConstruct("page.htm","layerID");

Where is "createRequest2" ever being called? You also have a call to a "createRequest" function that doesn't exist.

NB: There is now an AJAX-specific forum: forum1600

Apart from an obvious typo, your construction of the object is _no good_. You pass this to the createRequest2 to return this.conn, and then you are setting us effectively obj.conn in the method. All seems terrible mixed up and self-confusing. A quick clean up would be just call createRequest2 as a function.

createRequest2(this);[/tt]
At certain moment, you may be, or maybe not, requested to give privilege in moz. But, it depends.

Thanks tsuji. That helps.
