ADOBE FLASH MEDIA INTERACTIVE SERVER

Server-Side ActionScript Language Reference

Details

This handler is invoked before the data is parsed and can be used to call a custom parsing routine instead of the one

built in to Flash Player. The value of the

src parameter that is passed to the function assigned to

LoadVars.onData() can be either undefined or a string that contains the URL-encoded name-value pairs

downloaded from the server. If the

src parameter is undefined, an error occurred while downloading the data from

the server.

The default implementation of

LoadVars.onData() invokes LoadVars.onLoad(). You can override this default

implementation by assigning a custom function to

LoadVars.onData(), but LoadVars.onLoad() is not called

unless you call it in your implementation of

LoadVars.onData().

Example

The following example loads a text file and traces the content when the operation is complete:

var my_lv = new LoadVars();

my_lv.onData = function(src) {

if (src == undefined) {

trace("Error loading content.");

return;

}

trace(src);

};

my_lv.load("content.txt", my_lv, "GET");

LoadVars.onHTTPStatus()

myLoadVars.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.

Availability

Flash Media Server 2

Parameters

httpStatus A number; the HTTP status code returned by the server. For example, a value of 404 indicates that

the server has not found a match for the requested URI. HTTP status codes can be found in sections 10.4 and 10.5

of the HTTP specification.

Details

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 Interactive Server did not try to make the URL

request.

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

value of 0 is passed to your ActionScript code.
