ADOBE FLASH MEDIA INTERACTIVE SERVER

Server-Side ActionScript Language Reference

XML.onData()

my_xml.onData = function(src) {}

Invoked when XML text has been completely downloaded from the server or when an error occurs in downloading

XML text from a server. This handler is invoked before the XML is parsed, and you can use it to call a custom parsing

routine instead of using the Flash XML parser. The

src parameter is a string that contains XML text downloaded

from the server, unless an error occurs during the download. In this situation, the

src parameter is undefined.

By default, the

XML.onData() event handler invokes XML.onLoad(). You can override the XML.onData() event

handler with custom behavior, but

XML.onLoad() is not called unless you call it in your XML.onData() implemen-

tation.

Parameters

src A string or undefined; the raw data, usually in XML format, that is sent by the server.

Example

The following example shows what the

XML.onData() event handler looks like by default:

XML.prototype.onData = function (src) {

if (src == undefined) {

this.onLoad(false);

} else {

this.parseXML(src);

this.loaded = true;

this.onLoad(true);

}

};

You can override the XML.onData() event handler to intercept the XML text without parsing it.

XML.onHTTPStatus()

myXML.onHTTPStatus(httpStatus){}

Invoked when Flash Media Interactive Server receives an HTTP status code from the server. This handler lets you

capture and act on HTTP status codes.

The

onHTTPStatus() handler is invoked before onData(), which triggers calls to onLoad() with a value of

undefined if the load fails. After onHTTPStatus() is triggered, onData() is always triggered, whether or not you

override

onHTTPStatus(). To best use the onHTTPStatus() handler, you should write a function to catch the result

of the

onHTTPStatus() call; you can then use the result in your onData() and onLoad() handlers. If

onHTTPStatus() is not invoked, this indicates that Flash Media Server did not try to make the URL request.

If Flash Media Interactive Server cannot get a status code from the server, or if it cannot communicate with the

server, the default value of 0 is passed to your ActionScript code.
