Question

我知道这些问题会有一个明显的答案，但我已经花了两天多时间试图这样做而没有运气（我是一个Flex新手）基本上我正在尝试打开一个webView，将谷歌地图打开到数组中的位置

该位置来自于从facebook事件中获取的数组中的数据（工作正常并将显示数据）但我正在努力将此信息传递给webView.loadURL字符串

数组中我想要的数据是'data.location'（我遇到问题的代码位于代码段底部的itemrenderer中）

我尝试过很多不同的选择，现在我已经被困了

        } 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);

Answer 1

我需要做的就是将数据添加到括号中（不知道官方名称）这里是

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

和按钮/标签

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

将数组添加到URL字符串
