I have a flex application. In the wrapper jsp of the flex application, an html page, i have to capture the browser close event with an alert "DO you wish to close?", if the user clicks "yes", i have to call a flex function to handle the event. Can any one help !

There is already a question answered on capturing browser close event http://stackoverflow.com/questions/1631959/browser-window-close-event. – Manish Singh Sep 11 '11 at 06:16

1Please don't do this. It is really annoying to users. – Michael Aaron Safyan Sep 11 '11 at 07:15

On your body tag, add onunload event:
<body onunload="doStuffHere();">
...
</body>
and in your JS function (doStuffHere) call Flex to handle the event.
If, eventually, doStuffHere returns false, it cancels the close event.
You can also use onbeforedownload. See this Q&A for more details. You can use both of them, see why.

In javascript you have the onBeforeUnload event, hook on to that. You only cannot alter its appearance.
