I had this same problem, and the problem is deeper than it seems. I had
an element and I had to determine if it was visible or not, but
sometimes the element was NOT visible, even when it didn't have
"display: none" or "visibility: hidden". Turns out a parent DIV a few
levels up *was* hidden, and all it's children were thus hidden.
I've added a #visible? method to the modal_dialog branch which iterates
up to the top of the DOM tree checking to make sure every parent element
is visible. Note that this is a relatively SLOW call because the only
way to ensure an element is visible is to make sure every parent is visible.
If you place the following code in a file and require it you should be
able to do an "element.visible?" call.
class Element
# If any parent element isn't visible then we cannot write to the
# element. The only realiable way to determine this is to iterate
# up the DOM element tree checking every element to make sure it's
# visible.
def visible?
# Now iterate up the DOM element tree and return false if any
# parent element isn't visible or is disabled.
object = document
while object
begin
if object.style.invoke('visibility') =~ /^hidden$/i
return false
end
if object.style.invoke('display') =~ /^none$/i
return false
end
if object.invoke('isDisabled')
return false
end
rescue WIN32OLERuntimeError
end
object = object.parentElement
end
true
end
end
