what can watir's new "alert API" actually do?

Question

I just read that new Watir version (3.1.0) has "support for Alert API". What can I actually do with this API?

Is it meant for dealing with javascript popup windows? If so, what command can I use to click "OK" in popup window? Or how can I read title & text of popup window?

I tried "browser.alert.ok" after updating Watir to 3.1.0 but just got some error message...

(There is not yet any clear documentation about this, and trying to interpret the source code is not my strongest side...)

Answer 1

Alert API is for dealing with JavaScript popups.

browser.alert.ok should work. Could you provide the error message?

I am not sure about getting popup title, but you can get it's text with browser.alert.text

More information: http://watir.github.io/docs/javascript-dialogs/

Answer 2

browser.alert.ok should work. Could you provide the error message?

Sure. First, here is Watir code that I used:

require 'watir'
b = Watir::Browser.start "www.w3schools.com/js/tryit.asp?filename=tryjs_alert"
b.maximize
b.frame(:name, "view").button(:text, "Show alert box").click_no_wait
sleep 2
b.alert.ok

And here is the error message:
