Menu
I've been trying to create a small page and all it does is update some values from a source document. The page loads fine, but I don't get the results from the requested source. The .fail function runs, but the textStatus and errorThrown values don't appear in the alert() window that pops up.
I'm very new to javascript and jquery. I'm trying to bash this together with pieces found from the web to figure it out but nothing seems to be working. Mainly, it's the response I think I'm falling down on...
Anyway, here's the code:
<html>
<head>
<title></title>
<script type="text/javascript" src="~/Scripts/jquery-1.9.1.js"></script>
<script type="text/javascript">
function update() {
$.ajax({
type: "GET",
url: "http://192.168.2.86:15890/linearlist.xml",
dataType: "xml"
}).done(function (res) {
//alert(res);
}).fail(function (jqXHR, textStatus, errorThrown) {
alert("AJAX call failed: " + textStatus + ", " + errorThrown);
});
}
function GetData() {
update();
setTimeout(function () {
GetData();
}, 50);
}
});
</script>
</head>
<body>
<script type="text/javascript">
GetData();
</script>
<div class="result"> result div</div>
</body>
</html>
UPDATE:
I've update my code re: @Ian's answer. It's still not working, sadly. I'm not getting the textStatus or errorThrown results either. I've tried debugging with Internet Explorer through VS2012 but it's not getting me far. If I put the URL into a webpage, I can view the XML document.

$.get does not accept one parameter as an object literal; it accepts several: http://api.jquery.com/jQuery.get/#jQuery-get1
You might be thinking of the $.ajax syntax: http://api.jquery.com/jQuery.ajax/
Anyways, call it like:
$.get("http://192.168.2.86:15890//onair.status.xml", {}, function (res) {
var xml;
var tmp;
if (typeof res == "string") {
tmp = "<root>" + res + "</root>";
xml = new ActiveXObject("Microsoft.XMLDOM");
xml.async = false;
xml.loadXML(res);
} else {
xml = res;
}
alert("Success!");
}, "text");
Or use $.ajax:
$.ajax({
type: "GET",
url: "http://192.168.2.86:15890//onair.status.xml",
dataType: "text"
}).done(function (res) {
// Your `success` code
}).fail(function (jqXHR, textStatus, errorThrown) {
alert("AJAX call failed: " + textStatus + ", " + errorThrown);
});
Using the fail method, you can see that an error occurred and some details why.
Depending on what/where http://192.168.2.86:15890 is, you may not be able to make AJAX calls due to the same origin policy - https://developer.mozilla.org/en-US/docs/JavaScript/Same_origin_policy_for_JavaScript
I know you have some logic in your success callback, but I'm pretty sure if you specify the dataType as "text", the res variable will always be a string. So your if/else shouldn't really do much - the else should never execute. Either way, if you're expecting XML, it's probably easier to just specify the dataType as "xml".
