Re: [Htmlunit-user] Re: Javascript problem

[Dave K. <dko...@ve...>]

Thanks for the response.  I was really more interested in whether the 
javascript was legit or not.  I have
worked around the problem by recoding the javascript - not ideal, but it 
will work for me.

I do seem to have a broader problem I would like to ask about.  It appears 
that using
webClient.getPage(url); on the page in question (with recoded javascript) 
does not fully execute
the javascript.  Again, this is not my code, but the gist of the 
functionality is:
- original javascript embedded in page pulls down a larger javascript file 
from the server using
   document.write()
- this additional javascript sets functions for window.onload() and 
window.onunload() (as seen in my
   previous question)
- these functions call a bunch of other functions, the ultimate result of 
which is to fire off a message
   to another server to report some performance stats

I'm snooping the NIC on the server that receives the performance data and I 
am not seeing any indication
of a connection from the server running htmlunit.  I understand that the 
onunload() would not be run as
there is currently no event handler for it, but I thought the onload() 
would be run.

Let me ask, fundamentally, is the code below enough to be accomplishing 
what I expect?  Or do I need
to do more to actually execute the onload function?

Thanks,
Dave
