[Htmlunit-user] checking for alerts on a page

[Vinay M. <vin...@gm...>]

Hi,

I am using HtmlUnit to fill up a page that pops up javascript alerts
when certain buttons are clicked or when a textbox loses focus. I need
to be able to capture these alerts and fetch the messages conveyed
therein.

Is there a way to check for these alerts in an asynchronous manner ? 

In the sense,  is there anything else that I can do apart from :

1) designating an instance of "CollectingAlertHandler" to maintain a
list of alerts that might show up on a page
2) and then, keep checking if the list of alerts in
CollectingAlertHandler got populated everytime I enter a value on the
site ?


Basically, I am looking for an "event listener" that gets notified
whenever an alert shows up on a page. The "event listener" could then
delegate the handling of the event to an appropriate "event handler".

Does HtmlUnit support this kind of a feature ?

Does popping up of an alert qualify as a WebWindowEvent, so that I
could use a handler implementing WebWindowListener ?


Thanks and Best Regards
