[Htmlunit-user] Iframe With JavaScript as Src attribute

[Mehrdad R. <rez...@ya...>]

Hi Everyone,



I've been running into great difficult loading a page 
which includes iframes. I've been reading all the posts regarding problems with 
iframe, but they all seem to date to 2006 or early 2007; so, I'm hoping that 
someone has already found a solution. 

In my code, based on whether I disable JavaScript or 
enable it two different errors happen (note that for my situation,I do without 
JavaScript if it solves my problem). My code has nothing complicated, it just 
gets a page, and that's where the erorr happens. And also as you will see from 
the log that I have included below, these are all just 
iframes which display some adds and if I could somehow just ignore them or not 
download them, it would be great. Here's my code:

______________________

wc = new 
WebClient(BrowserVersion.INTERNET_EXPLORER_6_0);

wc.setJavaScriptEnabled(true);

wc.setCookiesEnabled(true);

wc.setThrowExceptionOnScriptError(false);

wc.setRedirectEnabled(true);

wc.setRefreshHandler(new 
ThreadedRefreshHandler());

DefaultJSDialogWindowHandler jsPopupHanlder = new 
DefaultJSDialogWindowHandler(); 

wc.setAlertHandler(jsPopupHanlder);

wc.setConfirmHandler(jsPopupHanlder);

wc.setPromptHandler(jsPopupHanlder);

HtmlPage loginPage = null;

loginPage = (HtmlPage) 
wc.getPage("http://my.monster.com/Login.aspx");

_____________________

If I enable the Javascript, only one iframe of one of the 
ads is loaded onto the page. 

But if I disable the JavaScript, then I get a 
NullPointerException and the log below (Note that I have included only 
the part of the log file which is relevent in order to make 
reading it easy, but I do have the longer version of the 
log.

Note that the page includes only two iframes and it seems 
that the frame called

AdFrame_1_MasterPage1:HeaderContent:Header_Default:BannerAd1


is loaded a first time with no problem, and then it is 
loaded a second time and that's when the page loading runs intotrouble.

 

I appreciate it if anyone could give me a feed back as to 
how to solve this problem. Any suggestion would

be greatly appreciated.



Thanks,

Orod
