phantomjs via watir-webdriver, not handling javascript alerts

Question

I’m trying to automate some tasks on a webpage, and part of it includes clicking a link that’ll show a javascript alert where you have to press “OK”. Trouble is, when it gets to that point, it fails with the following error

/Users/username/.gem/ruby/2.0.0/gems/selenium-webdriver-2.35.1/lib/selenium/webdriver/remote/http/common.rb:66:in `create_response': unexpected response, code=405, content-type="text/plain" (Selenium::WebDriver::Error::WebDriverError)

Searching online, it seems like the trouble may be related to ghostdriver and that maybe phantomjs can’t do it, but that notion seems a bit weird to me (it’s called phantom*js*, after all, and an alert is pretty basic javascript), but maybe I’m looking at it wrong.

Running the script with chrome, it works flawlessly.

Check this and let me know #11151722 – Whitaker

I still get the same error. – Diddle

Would you mind capture a screenshot to see if the alert box is there? – Saree

Nope, the alert box is not visible on the screenshot. – Diddle

Could the solution provided here help: #9216213? – Ontiveros

No, that also does nothing. – Diddle

Answer 1

There's a known issue where PhantomJS doesn't handle JavaScript properly. One workaround is to disable the alert box by running:

@browser.execute_script("window.confirm = function(){return true;}");

Basically, the steps you want to follow are:

1. Go to the page
2. Run the command above
3. Click 'Delete' (or whatever that triggers the alertbox)
4. And it will automatically click 'Ok' for you.

How can something have js in the name and handle javascript poorly? Thank you very much, I had a bounty on this that already expired, I didn’t think I’d get an answer. Is there anyway I can further repay you for the answer? – Diddle

I didn't understand your question clearly. Can you rephrase your question? – Nickynico

I was just venting on the first question — phantomjs has js in the name (for javascript), so it’s a bit ironic that it doesn’t handle javascript properly. The idea is that it is scriptable with javascript, yes, but still. Regarding the second question, is there anyway I can thank you further, besides accepting the answer? I had a bounty on this that unfortunately had already expired, so it feels a bit wrong that those points went to waste. – Diddle

Ha! I dont know. I just started using stackoverflow. ;) but I'm here to help other people as well. – Nickynico

Answer 2

Sure,

Before go to action run it:

browser.execute_script("window.confirm = function(){return true;}");

It's help confirm popup.
