将数组添加到 URL 字符串

Question

我知道这个问题会有一个简单明显的答案，但我已经花了两天多的时间试图做到这一点，但没有运气（我是 Flex 新手） 基本上我正在尝试打开一个 webView，它将打开谷歌地图到数组中的位置

该位置来自从 facebook 事件获取的数组中的数据（工作正常并且会显示数据），但我正在努力将此信息传递给webView.loadURL 字符串

我想要在数组中的数据是“data.location”（我遇到问题的代码位于代码片段底部的 itemrenderer 中）

我尝试了很多不同的选项，现在我陷入了困境

    {
        if(FacebookMobile.getSession() != null) {
            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);
    }

    private function handleGetEventsResponse(events:Object, fail:Object):void {
        if (events != null)
            facebookEvents = new ArrayCollection(events as Array);
        //else
            //status = "Error";

Answer 1

我需要做的就是将数据添加到括号中（不知道正式名称），这里是

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

按钮/标签

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