LoadVars
401
onLoad (LoadVars.onLoad handler)
onLoad = function(success:
Boolean
) {}
Invoked when a
LoadVars.load()
or
LoadVars.sendAndLoad()
operation has ended. If the
operation was successful,
my_lv
is populated with variables downloaded by the operation, and
these variables are available when this handler is invoked.
This handler is
undefined
by default.
This event handler is similar to
XML.onLoad
.
Availability:
ActionScript 1.0; Flash Lite 2.0
Parameters
success
:
Boolean
- A Boolean value that indicates whether the load operation ended in
success (
true
) or failure (
false
).
Example
For the following example, add a TextInput instance called
name_ti
, a TextArea instance
called
result_ta
, and a Button instance called
submit_button
to the Stage. When the user
clicks the Login button instance in the following example, two LoadVars objects are created:
send_lv
and
result_lv
. The
send_lv
object copies the name from the
name_ti
instance
and sends the data to greeting.cfm. The result from this script loads into the
result_lv
object, and the server response displays in the TextArea instance (
result_ta
). Add the
following ActionScript on Frame 1 of the Timeline:
var submitListener:Object = new Object();
submitListener.click = function(evt:Object) {
var result_lv:LoadVars = new LoadVars();
result_lv.onLoad = function(success:Boolean) {
if (success) {
result_ta.text = result_lv.welcomeMessage;
} else {
result_ta.text = "Error connecting to server.";
}
};
var send_lv:LoadVars = new LoadVars();
send_lv.name = name_ti.text;
send_lv.sendAndLoad("http://www.flash-mx.com/mm/greeting.cfm",
result_lv, "POST");
};
submit_button.addEventListener("click", submitListener);
