Firefox XMLHttpRequest not working

firsttube · Jun 15, 2006

I have been banging my head against the wall on this one.

Here is the code I have:

Code:

var url = "[URL unfurl="true"]http://myurl.com/getData.asp?type="[/URL] + type + "&what=" + what + "&where=" + where;
	if(window.XMLHttpRequest) {
		var req = new XMLHttpRequest();	
	} else if(window.ActiveXObject) {
		var req = new ActiveXObject("Microsoft.XMLHTTP");
	}
	
	req.open("GET", url, true);
	req.send(null);
if (document.implementation && document.implementation.createDocument)
	{
		var strXML = document.implementation.createDocument("","",null);
		strXML.async = false;
		alert(req.responseText);
		strXML.load(req.responseText);

} else if (window.ActiveXObject) {
		var strXML = new ActiveXObject("Microsoft.XMLDOM");
		strXML.async = false;
		strXML.loadXML(req.responseText)
		alert(req.responseText);
}

It works in IE, but not in FF. The line for alert(req.responseText) shows in IE but in FF it is empty and there are no errors in the javascript console.

any ideas?

[1] You do not implement onreadystatechange handler, so there would be a timing problem. You should therefore use synchronous version to guard against the timing problem.

>req.open("GET", url, true);
[tt]req.open("GET", url, [red]false[/red]);[/tt]

[2] You should set the netscape security manager on "UniversalBrowserRead" for cross-browser scripting. Like this.
[tt]
if(window.XMLHttpRequest) {
var req = new XMLHttpRequest();
[blue]try {
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");
} catch (e) {
alert("Permission could be denied for cross-browser scripting.");
}[/blue]
} else if(window.ActiveXObject) {
var req = new ActiveXObject("Microsoft.XMLHTTP");
}
[/tt]

Amendment
The message in the alert should be read like this.
[tt]
alert("Permission could be denied for cross-[red]domain[/red] scripting.");
[/tt]
