如何在Flex中刷新应用程序？

Question

我在Flex 4中设计了一个测验应用程序.最后我想重新加载我的应用程序(即在浏览器中刷新页面).最后,我将在警报中显示分数.之后我想重新加载当前的应用程序.我怎样才能做到这一点？

要使刷新在单击警报后才发生：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:mx="library://ns.adobe.com/flex/mx"
               xmlns:s="library://ns.adobe.com/flex/spark" xmlns:local="*" 
               >
    <fx:Script>
        <![CDATA[
            import mx.controls.Alert;
            import mx.core.FlexGlobals;
            import mx.events.CloseEvent;
            protected function refreshClicked(event:Event):void
            {
                Alert.show("Congratulations you won", 
                    "Hooray!", 
                    Alert.NO|Alert.YES, null, refreshFinish);
            }
            protected function refreshFinish(event:CloseEvent=null):void{
                if(event == null){
                    event = new CloseEvent("refreshFinish");
                    event.detail = Alert.YES;
                }
                if(event.detail == Alert.YES){
                    navigateToURL(new URLRequest(FlexGlobals.topLevelApplication.url), "_self");
                }
            }
        ]]>
    </fx:Script>
    <s:Button label="Alert and Refresh" click="refreshClicked(event)" />
</s:Application>

您可以通过从 Alert.show 的第三个参数或中删除“NO”选项来删除它。
