702 ActionScript classes
LoadVars constructor
public LoadVars()
Creates a LoadVars object. You can then use the methods of that LoadVars object to send and
load data.
Availability: ActionScript 1.0; Flash Player 6
Example
The following example creates a LoadVars object called
my_lv
:
var my_lv:LoadVars = new LoadVars();
onData (LoadVars.onData handler)
onData = function(src:String) {}
Invoked when data has completely downloaded from the server or when an error occurs while
data is downloading from a server. 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 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
.
Availability: ActionScript 1.0; Flash Player 6
Parameters
src :String
- A string or
undefined
; the raw (unparsed) data from a
LoadVars.load()
or
LoadVars.sendAndLoad()
method call.
Example
The following example loads a text file and displays content in a TextArea instance called
content_ta
when the operation completes. If an error occurs, then information displays in
the Output panel.
var my_lv:LoadVars = new LoadVars();
my_lv.onData = function(src:String) {
if (src == undefined) {
trace("Error loading content.");
