overriding javascript

[aidy lewis]

Hi,

I am trying to override js to bypass a js dialog:

This is what I have got:

require 'watir'

ie = Watir::IE.new
ie.goto("http://www.w3schools.com/JS/tryit.asp?filename=tryjs_confirm")
#ie.frame(:name, "view").button(:value, "Display a confirm box").click
ie.document.body.parentElement.execScript("window.confirm=function(){return
true;}")

I am getting unknown property or method `execScript'

Could anyone please direct me?

Execscript exists on the window object, drop the body call from your code and it should work:

Hi Charley,

Thanks for the advice but I am stilling having trouble overriding the js script.

require 'watir'

ie = Watir::IE.new
ie.goto("http://www.w3schools.com/JS/tryit.asp?filename=tryjs_confirm")

ie.document.parentWindow.execScript("'disp_confirm=function{return
true;}', 'JavaScript'")
ie.frame(:name, "view").button(:value, "Display a confirm box").click_no_wait

Hi Aidy,

I have changed "disp_confirm" with the earlier one you have supplied
"window.confirm" and removed "JavaScript" from the end and it works
fine for me.

require 'watir'

ie = Watir::IE.new
ie.goto("http://www.w3schools.com/JS/tryit.asp?
filename=tryjs_confirm")

ie.maximize
ie.document.parentWindow.execScript("window.confirm=function(){return
true;}")

ie.frame(:name, "view").button(:value, "Display a confirm
box").click_no_wait

Thanks,
Jagdeep

Hi Jagdeep,

I am still unable to override the confirm function. The result should
tell me that 'You pressed OK!'.

It seems that execScript is running as a DOS window flashes, however I
am just left with the dialog.

Do I need to change some js settings in IE.

Hi Aidy,

Got the error -
The problem is the script disp_confirm is being called from a frame,
and its this frames disp_confirm and window_confirm, that should be
overridden.
So this should be done on the page and also for all frames. (which is
going to call your overridden function)

require 'watir'
ie = Watir::IE.new
ie.goto("http://www.w3schools.com/JS/tryit.asp?
filename=tryjs_confirm")
ie.maximize

# override the frames window.confirm
ie.frame(:name, "view").document.parentWindow.execScript

("window.confirm=function(){return true;}")
ie.frame(:name, "view").button(:value, "Display a confirm
box").click_no_wait

Wow .. great way to get rid of these confirm boxes.. only have to get
this to work on firewatir tooo...
Anyways I have tried this on IE8 RC1 - 8.0.6001.18344

Hi Tony,

Certainly works, even though I have changed #click_no_wait to #click.

I think we need to put this example in the js pop-up wiki and we need
an example for alerts as well.

For Firewatir you could re-open the FireWatir class and use #$jssh_socket.send

class FireWatir::Firefox
def close_js_confirm
$jssh_socket.send("[js]\n", 0)
self.read_socket()
sleep 1
end
end

The trouble however with this method is that we will never know if it
executes the js or not or does what it is supposed to do.

I tried this
require 'firewatir'

class Element
def close_js_confirm
assert_exist
@container.js_eval("window.confirm = function(){return true;}")
sleep 1
end
end

ff = FireWatir::Firefox.new
ff.goto("http://www.w3schools.com/JS/tryit.asp?
filename=tryjs_confirm")
ff.frame(:name, "view").button(:value, "Display a confirm
box").close_js_confirm
ff.frame(:name, "view").button(:value, "Display a confirm box").click

But it is not working for me. I tried the same js in firebug
navigating to that frame but in vain :(

Any ideas?

Regards,
Sai
