Installing

Simply include the jQuery library, and this library in your page:

<script src="jquery-1.8.1.js"></script>
<script src="jquery.xmlrpc.js"></script>

This was built upon jQuery 1.8.1. It will probably work with old versions, and will probably continue to work with new versions.

Using

The jQuery.xmlrpc function is the main work-horse of this library. Call it like so:

$.xmlrpc({
    url: '/RPC2',
    methodName: 'foo',
    params: ['bar', 1, 4.6, true, [1, 2, 3], {name: 'value'}],
    success: function(response, status, jqXHR) { },
    error: function(jqXHR, status, error) { }
});

It takes all of the same arguments as jQuery.ajax, so refer there for more documentation. The two new keys added are:

methodName
This is method put in the <methodName> element from XML-RPC. It should be a string. The XML-RPC service you are communicating with will determine valid method names you can call.
params

An array of parameters to send. Specify an empty array, or do not supply this key at all if you do not want to send any parameters.

See the docs section on [Encoding and Decoding XML-RPC Documents][encoding] for more information.

Getting data back

When the XML-RPC call returns, the contents of the <params> element are parsed into JSON and supplied to the success callback of the AJAX call as the first parameter, much like a JSON request.

Handling errors

If any HTTP errors occur during transport, the normal jQuery AJAX error handling will be used. If the XML-RPC service successfully replies, but replies with a <fault> response, an $.xmlrpc.XmlRpcFault is thrown. This error will be sent as the third parameter to the error callback of the AJAX call, as with other errors.
