Compliance Issues with Opera

[prgmrgirl]

Hey guys,
I'm trying to test a webpage on Opera. It works fine in IE and Firefox. I pared down all the javascript trying to isolate the problem but nothing helps.

The details:
Testing the page on a machine running XP Pro. I'm using an aspx file on localhost and running the page by right-clicking and Open With -> Opera.

What happens?
JavaScript - file://localhost/folder/pathtohtmlfile.htm
Event thread: click
Error:
Unhandled exception: [Object JavaObject]

The abbreviated html:
<input type=button value="Press the Button" id="btnTest" onclick="getProducts();"/>

The abbreviated javascript:

function createRequest()
{

	var xmlHttp=null;
	try
	{
		// Firefox, Opera 8.0+, Safari
		xmlHttp=new XMLHttpRequest();
	}
	catch (e)
	{
		// Internet Explorer
		try
		{
			xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
		}
		catch (e)
		{
			xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
		}
	}
	return xmlHttp;
}

function getProducts()
{
	request = createRequest();
	if (request==null)
	{
		alert ("Your browser does not support AJAX!");
		return;
	} 

	request.onreadystatechange=stateChanged;
		if (typeof netscape != 'undefined' && typeof netscape.security !='undefined') 
		{
			netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserRead');
		}
	request.open("GET",url,true);
	request.send(null);

}

function stateChanged()
{
	if (request.readyState==4)
	{ 
		alert(request.responseText);
	}

}

Can anyone see what I am missing here? The error I get from Opera is not helpful at all...

Thanks guys!

- At what stage do you get the error?

- Which version of Opera are you testing it wit? (have you tried the latest version?)

- Do you have a URL to the full page? If so, can you provide steps to reproduce the error?

Hey Dan (that's one of my favorite songs btw ),

- At what stage do you get the error?
As soon as I click the button that runs the javascript.

- Which version of Opera are you testing it with? (have you tried the latest version?)
Latest version

- Do you have a URL to the full page? If so, can you provide steps to reproduce the error?
It calls an aspx page on localhost so its not a page you can use. However, I know the aspx page is good because it works without a hitch on IE and Firefox.

Basically what its doing is getting a string value from an aspx page (using ajax) and displays it in an alert.

So, Feherke, to answer your question:
url =

http://localhost/somewebfolder/getString.aspx

If you substitute that page with some aspx on localhost that simply returns a string, it should work in firefox and IE.

I suspect that the fact that it is accessing a page on localhost might be the problem. I had to do a small work around to get it to work in Firefox because it was complaining that it didn't have rights to open the page.

I wonder if Opera requires some sort of security setting to be set or something. I find it odd that its not really giving me an error. This is what it says in the error console:

JavaScript - file://localhost/folder/pathtohtmlfile.htm
Event thread: click
Error:Unhandled exception: [Object JavaObject]

When I run it in netscape, I don't get an error at all but neither does it return a value.

It's all very strange. Why does it have to be so difficult to make this stuff cross-browser??

Ah - that could be the hint we need... you are using the file:// protocol. AJAX wants to use http:// for it's URLs. So you need to make sure the intial file and any file accessed through AJAX is on the dame domain, using the same protocol, and using http:// (or

https://).

See if merely putting everything onto a proper web server fixes your problems.

Cheers,
Jeff

Make sure your web page and css validates properly against the doctype you have chosen - before you attempt to debug a problem!

Failing that, could you upload the pages to somewhere we can access and then post the URL?
