Refresh/Reload Flex App using JavaScript code.

February 12, 2008

When you search to accomplish a task in Flex and can’t do it, then look for it in JavaScript because many of things that are not possible in Flex are possible using JavaScript which is the backbone of your Flex App.

I had a requirement were i wanted to refresh/reload the Flex App ,but i couldn’t do it in Flex and finally i realized that it may be possible using JavaScript then i went for it and coded, “WOW” i said to my self because it worked ,my App got reloaded/refreshed.

Then decided to post it in Blog, because it may help out other Flex lovers.

Code Example:

<?xml version=”1.0″ encoding=”utf-8″?>
<mx:Application xmlns:mx=”; layout=”absolute”>
<mx:Button x=”83″ y=”196″ label=”Button” click=”reloadpage(event)”/>
private function reloadpage(event:MouseEvent):void
var ref:URLRequest = new URLRequest(“javascript:location.reload(true)”);
navigateToURL(ref, “_self”);

Here on click of Button the App is reloaded/refreshed.Isn’t cool.

JavaScript function to travel to a WEB Page : redirect()

January 31, 2008

In flex we use navigateToUrl () method to traverse to a WEB page, usually with a link Button or Button.

So how to do this with Javascript code behind the flex App, the solution is simple with a line a code.

The line is :


specify the link in the double quotes.


In flex iam having Button which calls the function redirect() at JS,which contains the line of code, then definition would be as below..,

Code at Flex app:

<mx:Button id=”btn” click=”b()”/>


private function b():void




Code at JS/html wrapper:

<script language=”javascript”>

function redirect()





Now on click Button the page will travel to the Google Page.
