What follows is a working solution and some lessons learned in
handling popups. Thanks for everyone that has helped along the way.
I needed to handle confirmation popups. After trying autoit based
solutions without success, I decided to try a solution that has worked
for me in the past - overriding the javascript that displays the
popup.
The two things that made this hard are : 1) I was working within a
frame, 2) IE.
When you are working within a frame environment, you must call
execScript on the frame's window. This is because IE - unlike all
other browsers - only passes a reference to your function. The
function will get called, but any references to the js object 'window'
will be to the window where the js resides, not the window for the
frame containing the button. I would probably not have this problem
with any other browser (although I haven't actually tested it as my
app doesn't run on anything but IE)
The final working code looks like:
onclick_js = "function(event){"
onclick_js += " event = window.event;"
onclick_js += " if(event){"
onclick_js += " alert('found event');"
onclick_js += " } else { "
onclick_js += " alert('no event available'); "
onclick_js += " }"
onclick_js += "}"
js =" var myelem=document.getElementById('" + html_id + "');"
js +=" if(myelem){ "
js +=" myelem.onclick=" + onclick_js + ";"
js +=" }"
@browser.frame(:id, 'top_frame').document.parentWindow.execScript
(js, "javascript")
Please note the last line. Here is an alternative that did NOT work.
@browser.document.parentWindow.execScript(js, "javascript") # seems
to work, but no event object is available to handler!!
Thanks and I hope this helps someone else.
