Ie.link(:text, "Next").click

ruby-talk
1

I am navigating through web page using WATIR..

and as you know, many web pages has "Next" link that allows us to go to
the next page by clicking this "Next" link.

Now when the page reaches the last page, although "Next" is present,
but it is no longer a link.

At this point, if my code still goes to:

ie.link(:text, "Next").click

then I get the error message..

Is there anyway I can have WATIR check whether "Next" is link or not,
and if it is a link, then go to

ie.link(:text, "Next").click,

and if it is just plain text, do not go to ie.link(:text,
"Next").click??

thanks.

As others have replied to one of your other posts on this topic, why not
trap the error using "rescue", and move on from there?

if ie.link(:text, "Next").exists?
  ie.link(:text, "Next").click
end

Like this:

begin
  # error-creating code here
rescue
  # error-handling cede here
end

Working example:

···

-------------------------------------

#!/usr/bin/ruby -w

begin
  x = 1/0
rescue Exception => e
  puts "trapped error: " + e
end

-------------------------------------

Output:

trapped error: divided by 0
