我知道這個問題會有一個簡單明顯的答案,但我已經花了兩天,現在試圖做沒有運氣(我是一個Flex新手) 基本上我試圖打開一個webView,將打開谷歌地圖到一個數組中的位置添加數組到URL字符串

該位置來自從facebook事件(這工作正常,將顯示數據)數組中的數據,但我很努力將此信息傳遞給webView。 loadURL字符串

我想在數組中的數據是'data.location'(我有問題的代碼是在代碼片段底部的itemrenderer中)

我已經嘗試了許多不同的選擇,現在我被困

      getEvents() 
     } else { 
      eventsDataGrid.visible=false 
      NotLogin.visible=true 
     } 

    } 

    private function getEvents():void { 
     var fql:String = "select name, location, pic, start_time from event where creator = 148839887036 and eid in (select eid from event_member where uid=148839887036)"; 
     FacebookMobile.fqlQuery(fql, handleGetEventsResponse);

所有我需要做的是,將數據添加到括號(不知道的官方名稱),這是

protected function directions_click (location:String):void 
           { 
            navigateToURL(new URLRequest('http://maps.google.co.uk/maps?q=' + location)); 
           } 

和按鈕/標籤

<s:Label text="Get Directions" fontFamily="lucida grande" fontSize="14" color="#3b5998" click="directions_click(data.location)"/>
