Troubleshooting the Connect Button in Chapter 3 of 'Mastering XMPP Development with JavaScript and jQuery'

Currently, I am in the process of setting up an xmpp client on my website and to familiarize myself, I am following the examples provided in a book. Example 3 has been successfully implemented by copying the code, with the only alterations being the strophe connection address changed to "http://localhost:5280/http-bind/" and adjusting the script paths. Upon directing to localhost/hello.html, it loads as expected. However, upon entering my credentials and clicking connect, nothing seems to happen. Could this issue be related to a JavaScript error?

You can view the code identical to chapter 3 here

Edit: The reason behind the connect button not functioning properly was due to incorrectly loaded strophe and flxhr js scripts. As a result, the connect button now works correctly, triggering the bound connect function and closing the dialog box. Nevertheless, despite these changes, the connected and disconnected functions remain unresponsive after clicking connect. What could be causing this issue?

Answer №1

To effectively troubleshoot Strophe.js issues, monitoring the wire traffic is key. There are two ways you can do this.

1) Utilize the network panel in Firebug or Chrome/Safari's developer tools. By observing all the posts and responses from Strophe in this panel, you can identify any potential errors stemming from the initial XMPP setup and authentication. If there are connectivity issues, a single POST request may display an error message. In such cases, sharing the error details could help with diagnosis.

2) Implement a logging function for Strophe to track its activity. This approach is particularly useful when setting up a BOSH session encounters difficulties. To set this up:

connection.rawInput = function (data) { console.log(" IN: " + data); };
connection.rawOutput = function (data) { console.log("OUT: " + data); };

Additionally, instead of using console.log to log information, you can choose to have it displayed within the DOM.

If you require further debugging insights, try:

Strophe.log = function (lvl, msg) { console.log("LOG: " + msg); };

Referencing Chapter 4 might also provide additional techniques for debugging purposes.

Answer №2

I gave the example a shot and it actually worked for me. If you haven't made any changes to the JavaScript code, then the issue might stem from your ejabberd server setup. It's likely related to your hostname configuration in the ejabberd.cfg file. You could try a few things:

  1. Check that "localhost" is included in the following line of the ejabberd.cfg file:

    {hosts, ["localhost"]}.

  2. If your hostname checks out, consider increasing your ejabberd log level to 5 and restarting ejabberd. Share any error messages you encounter here so we can troubleshoot together.
