FLASH® LITE™ 2.x - Adobe Help and Support

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.
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);
