[Htmlunit-user] Problems with Facebook anchor

[Jerome <jer...@16...>]

Hi,
I'm trying to bulid an application on Facebook with HtmlUnit, So I want to click the buttons on the profile. But I can't find the anchor.
After logging into the Facebook, I need to press the button like "About". How could I find the htmlelement?
I have tried the function getAnchorByHref(), but failed. I am sure that the attribute was right when using the function.
I think it may have some problems with javascript, or I can get this anchor and then click it.

By the way, how can I know about the page was loaded successfully by javascript? I have read the article like
http://htmlunit.sourceforge.net/faq.html#AJAXDoesNotWorkBut I am still confused about it. 

Please help to conquer this problem, thanks!
