下面是代码:
public class Schem
{
public var info:String="";
public function Schem()
{
}
public function loadCurrentSchem():void
{
var ro:RemoteObject = new RemoteObject("Hibernatetest");
ro.endpoint = "http://Jesus/blazeds/messagebroker/amf";
ro.addEventListener(ResultEvent.RESULT,onResult);
ro.getCells();
info = info + "Loader called ... \n";
}
public function onResult(event:ResultEvent):void
{
var array:ArrayCollection = event.result as ArrayCollection;
info = info + "Schemlength = " + String(array.length)+ "\n";
}
private function onFault(event:FaultEvent):void
{
info = info + "Errorhandler Called";
}
//Eventhandlers
//Getters, Setters
}
不幸的是,当我调用loadCurrentSchem()函数时,它没有到达eventHandler。怎么了?
这就是我打电话给班级的方式:
<fx:Script>
<![CDATA[
import argoseye.main.Golem;
import argoseye.main.Schem;
import mx.collections.ArrayCollection;
import mx.rpc.AsyncToken;
import mx.rpc.Responder;
import mx.rpc.events.FaultEvent;
import mx.rpc.events.ResultEvent;
import mx.rpc.remoting.RemoteObject;
protected function button1_clickHandler(event:MouseEvent):void
{
var schem:Schem = new Schem();
schem.loadCurrentSchem();
textfeld.text = schem.info;
}
]]>
</fx:Script>
有
答案 0 :(得分:0)
问题是你没有正确确保结果处理程序正确调用。问题是当你使用时:
textfeld.text = schem.info;
您已设置值:
info = info + "Loader called ... \n";
作为文本字段的文本,并且在结果处理程序中不会更改此值。
您至少可以通过两种方式解决此问题:
Schem
扩展您的EventDispatcher
课程,并将事件元数据放在那里。班级:
[Event(name="result", type="mx.rpc.events.ResultEvent")]
[Event(name="fault", type="mx.rpc.events.FaultEvent")]
public class Schem extends EventDispatcher
{
public var info:String="";
public function Schem()
{
}
public function loadCurrentSchem():void
{
var ro:RemoteObject = new RemoteObject("Hibernatetest");
ro.endpoint = "http://Jesus/blazeds/messagebroker/amf";
ro.addEventListener(ResultEvent.RESULT,onResult);
ro.addEventListener(FaultEvent.FAULT,onFault);
ro.getCells();
info += "Loader called ... \n";
}
private function onResult(event:ResultEvent):void
{
var array:ArrayCollection = event.result as ArrayCollection;
info += "Schemlength = " + String(array.length)+ "\n";
dispatchEvent(event);
}
private function onFault(event:FaultEvent):void
{
info += "Errorhandler Called";
dispatchEvent(event);
}
//Eventhandlers
//Getters, Setters
}
然后在你的MXML课程中:
<fx:Script>
<![CDATA[

import argoseye.main.Schem;
import mx.collections.ArrayCollection;
import mx.rpc.AsyncToken;

import mx.rpc.events.ResultEvent;
import mx.rpc.remoting.RemoteObject;
protected function button1_clickHandler(event:MouseEvent):void
{
var schem:Schem = new Schem();
schem.addEventListener(ResultEvent.RESULT,onResult);
schem.addEventListener(FaultEvent.FAULT,onFault);
schem.loadCurrentSchem();
textfeld.text = schem.info;
}
private function onResult(event:ResultEvent):void
{
textfeld.text = event.currentTarget.info;
}
private function onFault(event:FaultEvent):void
{
textfeld.text = event.currentTarget.info;
}
]]>
</fx:Script>
Schem
上课:
public class Schem
{
[Bindable]
public var info:String="";
public function Schem()
{
}
public function loadCurrentSchem():void
{
var ro:RemoteObject = new RemoteObject("Hibernatetest");
ro.endpoint = "http://Jesus/blazeds/messagebroker/amf";
ro.addEventListener(ResultEvent.RESULT,onResult);
ro.addEventListener(FaultEvent.FAULT,onFault);
ro.getCells();
info += "Loader called ... \n";
}
private function onResult(event:ResultEvent):void
{
var array:ArrayCollection = event.result as ArrayCollection;
info += "Schemlength = " + String(array.length)+ "\n";
}
private function onFault(event:FaultEvent):void
{
info += "Errorhandler Called";
}
//Eventhandlers
//Getters, Setters
}
在MXML中:
<fx:Script>
<![CDATA[
import argoseye.main.Golem;
import argoseye.main.Schem;
import mx.collections.ArrayCollection;
import mx.rpc.AsyncToken;

{
schem = new Schem();
schem.loadCurrentSchem();
}
]]>
</fx:Script>
<s:Label id="textfeld" text="{schem.info}" />
希望这有帮助! :)
