import mx.controls.Alert;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;

//调用失败
protected function service_faultHandler(event:FaultEvent):void
{
Alert.show("失败了:"+event.message,"提示");
}

//调用成功
protected function service_resultHandler(event:ResultEvent):void
{
Alert.show("成功了:"+event.result as String,"提示");
}

//调用
protected function button1_clickHandler(event:MouseEvent):void
{
//第一种传值方式
//service.send();

//第二种传值方式 通过send()方法传值 send方法中传递参数
//定义一object对象
var val:Object=new Object();
//分别将文本框username，password的值传递到后台
//object对象.参数名=值 传值操作
val.username=txtusername.text;
val.password=txtpassword.text;
service.send(val);
}
