Question

我有一个应用程序，当前从Facebook获取事件数据并将其显示在列表中

<s:List id="eventsDataGrid" width="100%" height="100%" dataProvider="{facebookEvents}">
        <s:itemRenderer>
            <fx:Component>
                <s:ItemRenderer>
                    <fx:Script>
                        <![CDATA[
                            import com.facebook.graph.utils.FacebookDataUtils;
                            private function time2DateStr(time:String):String {
                                return FacebookDataUtils.stringToDate(time).toLocaleString();
                            }

                        ]]>
                    </fx:Script>
                    <s:HGroup paddingBottom="10" paddingTop="10">
                        <s:Image source="{data.pic}"/>
                        <s:VGroup width="100%">
                            <s:Label text="{data.name}" fontWeight="bold" width="100%"/>
                            <s:Label text="Where: {data.location}" id="locationtxt"/>
                            <s:Label text="When: {time2DateStr(data.start_time)}"/>

                        </s:VGroup>
                    </s:HGroup>
                </s:ItemRenderer>
            </fx:Component>
        </s:itemRenderer>
        </s:List>

我正在尝试添加一个按钮，该按钮将在webView中显示位置，但我无法让应用程序使用数组中的data.location将其用于Google地图（我只是添加data.location详细信息到谷歌地图URL的末尾，然后使用地图搜索该位置我可以让按钮工作，但它不会搜索位置它只是在Flash构建器中显示错误（我假设是由于我没有正确地将数据添加到字符串）或搜索“data.location” 以下是将加载URL但没有位置的当前代码

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Array数据添加到变量
