WebKit in AIR doesn’t support E4X syntax, so the method used to create the XML document in the previous example
does not work in JavaScript code. Instead, you must use the DOM methods to create the XML document or create the
document as a string and use the JavaScript DOMParser class to convert the string to XML.
The following example uses DOM methods to create an XML-RPC message and an XMLHttpRequest to conduct the
web service transaction:
XML-RPC web service request
function makeRequest()
{
var requestDisplay = document.getElementById( "request" );
var resultDisplay = document.getElementById( "result" );
var request = {};
request.URL = "http://services.example.com/xmlrpc/";
request.method = "test.echo";
request.HTTPmethod = "POST";
request.parameters = {};
request.parameters.api_key = "123456ABC";
request.parameters.message = "Able was I ere I saw Elba.";
var requestMessage = formatXMLRPC( request );
xmlhttp = new XMLHttpRequest();
xmlhttp.open( request.HTTPmethod, request.URL, true);
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4) {
resultDisplay.innerText = xmlhttp.responseText;
}
}
xmlhttp.send( requestMessage );
requestDisplay.innerText = xmlToString( requestMessage.documentElement );
