So, I wrote some JavaScript to grab an xml file from my desktop and display it on an html page. However, I now have added my xml file to a webserver (mongoose). I want to call the file from that server, but whenever I call the file from the server it dosen't work, but when I call it from my desktop it loads fine.
I want to swap
xmlhttp.open("GET","Devices.xml",false);
with
xmlhttp.open("GET","http://localhost:8080/Devices.xml",false);
Here is the code
<html>
<head>
<script type="text/javascript">
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else {// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","Devices.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
// the <Device> list
x = xmlDoc.getElementsByTagName('Device');
// make a function that extracts the attributes out of a Node
function getDeviceAttributes(dvc) {
var name = dvc.getAttribute("name");
var uuid = dvc.getAttribute("uuid");
var id = dvc.getAttribute("id");
return "<p>name: " + name + "<br> uuid: " + uuid + "<br> id: "+ id + "</p>";
}
// loop through the list
// assuming order doesn’t matter
var txt = '';
for (var i = x.length; i--;) {
txt += getDeviceAttributes(x[i]);
}
//show the result on page load
window.onload = function() {
document.getElementById("showDevices").innerHTML = txt;
};
</script>
</head>
<body>
<div id='showDevices'></div>
</body>
</html>
Does anyone know how I can get this to work?
I have been told to use AJAX and Jquery, but I have no idea how to or even where to begin.

It looks like you are repeating a lot of work that jQuery can do for you. Check out the documentation for the Get request method
So something like this:
$.get('http://localhost:8080/Devices.xml', function(data) {
$('#showDevices').html(data);
});
I believe that is the jQuery for what you are trying to do. Hope that helps.

Just some generic advice, you could also use the .load() ajax function if you didn't want to parse the response and this:
window.onload = function() {
document.getElementById("showDevices").innerHTML = txt;
};
can be done in jQuery like this $("#showDevices").html(txt);
