zxml library XMLHttpRequest() problem

dastard · #1 (**permalink**) May 25th, 2009, 04:16 PM

I have been using the excellent zxml library for the last year so on a site hosted on Ubunu 6.04. I have now migrated to Ubuntu 8.04 and the Ajax now fails. I have narrowed the problem to the line:-

Code:

        return new XMLHttpRequest();

in zxml.js. Using IE8 I get the error "Object doesn't suppot this property or method" (IE7 gave similar error). Strangely, if after loading the page I 'refresh' the browser the code then works.

Can anyone explain what is going on here?

Thanks.

Howdy, dastard.

I can't think of anything off the top of my head that would cause this. Can you provide a link to the page giving you the error?

Thanks for replying Jeremy. I seem to have inadvertently found the solution myself. The page is on an intranet and on trying to find the minimum code to replicate the problem I found that

Code:

<html>
<head>
<title>Ajax test</title>
<script type="text/javascript"src="js/zxml.src.js"></script>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<script language="javascript" type="text/javascript">
    var oXHR = zXmlHttp.createRequest();   
</script>
</head>

gives an error whilst

Code:

<html>
<head>
<title>Ajax test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<script type="text/javascript"src="js/zxml.src.js"></script>
<script language="javascript" type="text/javascript">
    var oXHR = zXmlHttp.createRequest();   
</script>
</head>

is ok.

Thus calling the js library before the meta tag does not work. Perhaps this is to be expected - I don't know. Perhaps you could comment? Anyway it's working now!

Thanks again,
Dastard
