pb avec ExternalInterface

khayem · 16/09/2008, 12h35

j'ai un soucis avec la classe ExternalInterface.En faite j'essaye de récupérer une fonction javascript mais mon fichier.as ne voit pas la fonction javascript(peut etre un pb de mapping entre les fichiers), en tout cas voici les codes des différents fichiers:

pour résumer ce code récupère les caractéristiques du système et du navigateur et les affiche dans un tableau, or dans mon cas seul les caractéristiques du système s'affiche.

fichier.mxml :
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
xmlns:example="com.example.programmingas3.capabilities.*"
xmlns="*"
layout="vertical"
horizontalAlign="left"
creationComplete="initApp();">

<mx:Script>
<![CDATA[
import com.example.programmingas3.capabilities.*;
private function initApp():void {
var dp:Array = CapabilitiesGrabber.getCapabilities();
capabilitiesGrid.dataProvider = dp;
}
]]>
</mx:Script>

<mx:Label id="title" text="CapabilitiesExplorer Example" fontSize="24" fontStyle="bold" />
<mx:Label id="subtitle" text="From Programming ActionsScript 3.0, Chapter 23: Client system environment" fontSize="12" />

<mx

anel title="System capabilities" width="100%" height="100%">
<mx

ataGrid id="capabilitiesGrid" editable="false" width="100%" height="100%" dropShadowEnabled="false">
<mx:columns>
<mx:Array>
<mx

ataGridColumn dataField="name" headerText="Name" />
<mx

ataGridColumn dataField="value" headerText="Value" />
</mx:Array>
</mx:columns>
</mx

anel>
