w3schools example showcasing the power of AJAX

How can I run this example on my local machine?

http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_httprequest_js (page no longer available)

I want to access the XML file hosted on w3schools without moving it to my machine. Can I run the HTML and JavaScript code locally? I attempted changing the third to last line from:

<button onclick="loadXMLDoc('note.xml')">Get XML</button>

to:

<button onclick="loadXMLDoc('http://www.w3schools.com/ajax/note.xml')">Get XML</button>

I thought this change would make it work, but it doesn't seem to be helping. Any suggestions?

Answer №1

To access the content, simply enter the complete URL into your browser's address bar to retrieve it. Then you can copy and paste the information for offline storage. Keep in mind that JavaScript is restricted from fetching data outside of its own domain by default, unless additional measures are taken due to the Same Origin policy, a security protocol.

Answer №2

It is not possible to use AJAX across different domains. To work around this limitation, the XML file should be relocated to the same server where the site files are hosted and accessed from there.

Answer №4

When implementing AJAX, remember to include the code snippet below within your function:

try {
    netscape.security.PrivilegeManager.enablePrivilege("UniversalPreferencesRead");   
  } catch (e) {
    alert("Error occurred");
}

It's important to note that this specific code is designed for Firefox compatibility only. There are additional parameters that can be utilized with enablePrivilege for enhanced functionality.
