Refresh Flex page using Javascript function in AS3

Hi,
In Flex once the values get updated we need to refresh the felx content dynamically. Here i did one example for refresh the flex page by calling the javascript function when click the button in flex application. Its very simple way to refresh the flex page whenever you wants by using the following javascript function calls.

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import flash.net.navigateToURL;
private function onRefresh():void
{
var ref:URLRequest = new URLRequest("javascript:location.reload(true)");
navigateToURL(ref,"_self");
}
]]>
</mx:Script>
<mx:Button label="Refresh" click="onRefresh()"/>
</mx:Application>
