I am trying to complete the NewsTicker widget. I'm writing newsticker.js right i even downloaded the code and it still will not work.
if ( isset( $_GET["http://www.ledger-enquirer.com/mld/ledgerenquirer/news/breaking_news/rss.xml"] ) ) {
$remoteUrl = $_GET["http://www.ledger-enquirer.com/mld/ledgerenquirer/news/breaking_news/rss.xml"];
$xml = file_get_contents($remoteUrl);
That is the url that the feed i want is located. The following is the include section of the default.htm file:
<link rel="stylesheet" type="text/css" href="css/newsticker.css" />
<script type="text/javascript" src="js/zxml.js"></script>
<script type="text/javascript" src="js/xparser.js"></script>
<script type="text/javascript" src="js/newsticker.js"></script>
<script type="text/javascript">
function init() {
var newsTicker = new NewsTicker();
newsTicker.add("http://www.ledger-enquirer.com/mld/ledgerenquirer/news/breaking_news/rss.xml");
}
onload = init;
And this is my newsticker.js Xparser initiation:
NewsTickerFeed.prototype.populateTicker = function (sXml) {
var oParser = new XParser("http://www.ledger-enquirer.com/mld/ledgerenquirer/news/breaking_news/rss.xml", true);
var spanLinkContainer = document.createElement("span");
var aFeedTitle = document.createElement("a");
aFeedTitle.className = "newsTicker-feedTitle";
aFeedTitle.href = oParser.link.value;
aFeedTitle.target = "_new";
aFeedTitle.innerHTML = oParser.title.value;
spanLinkContainer.appendChild(aFeedTitle);
for (var i = 0; i < oParser.items.length; i++) {
var item = oParser.items[i];
var aFeedLink = document.createElement("a");
aFeedLink.href = item.link.value;
aFeedLink.target = "_new";
aFeedLink.className = "newsTicker-feedItem";
aFeedLink.innerHTML = item.title.value;
spanLinkContainer.appendChild(aFeedLink);
}
You can see the javascript errors at this url. http://www.thrivenews.com/NewsTicker/
I'm getting 2 errors right now. one is "Xparser is not defined" the other is in the php "no element found"...
Please, I would love any help.....

I'm at work; therefore, I cannot access your web site (network Nazis). I can, though, comment on the code you've posted. =)
The main thing I see are the changes you've made to the code. From what I'm seeing, they are unnecessary changes. The widget is designed to pick up any RSS/Atom feed, so all you have to do is create a NewsTicker object and add a feed:
var myNewsTicker = new NewsTicker();
myNewsTicker.add("http://www.ledger-enquirer.com/mld/ledgerenquirer/news/breaking_news/rss.xml");That should get it working for you.

I did what you suggested And I'm getting a new javascript error now.
Error: oToAppend has no properties
Source File: http://www.thrivenews.com/NewsTicker/js/newsticker.js
Line: 22
And that is an unmodified version of the newsticker.js file. I just pulled it off the site.
Here is the code for the html page that I'm testing the ticker on.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
<title>Ajax News Ticker</title>
<link rel="stylesheet" type="text/css" href="css/newsticker.css" />
<script type="text/javascript" src="js/zxml.js"></script>
<script type="text/javascript" src="js/xparser.js"></script>
<script type="text/javascript" src="js/newsticker.js"></script>
<script type="text/javascript">
var myNewsTicker = new NewsTicker();
myNewsTicker.add("http://www.ledger-enquirer.com/mld/ledgerenquirer/news/breaking_news/rss.xml");
</script>
</head>
<body>
</body>
</html>
I would love some help... Thanks for helping me get this down to one error.

The creation of a NewsTicker object much take place when the page loads. This is a necessity because the HTML elements created by the NewsTicker is appended to either the document's body, or the supplied HTMLElement passed to the constructor. Running the script when the page loads ensures the document is completely loaded, and the HTML elements can be appended to the document. Otherwise, an error is thrown (the one you're seeing) stating that the element doesn't exist.

Ok I'm getting no errors now I stuck that myNewsticker into a function. But it's still not working. And I have now errors.
<link rel="stylesheet" type="text/css" href="css/newsticker.css" />
<script type="text/javascript" src="js/zxml.js"></script>
<script type="text/javascript" src="js/xparser.js"></script>
<script type="text/javascript" src="js/newsticker.js"></script>
<script type="text/javascript">
function init(){
var myNewsTicker = new NewsTicker();
myNewsTicker.add("http://www.ledger-enquirer.com/mld/ledgerenquirer/news/breaking_news/rss.xml");
}
</script>
This is a new feat though no errors. I guess I could go try it in IE havent done that but I doubt it will work. Thanks for all your help and if you have any more please feel free....
