Re: [Htmlunit-user] HTMLUnit does not seem to execute the Javascript

[Vasudevan C. <vco...@gm...>]

HI Ahmed,

   Upon further analysis, it was determined that JS was executing the src
in img tag.

    The javascript was executing an <img> tag. Since HTMLUnit does not
download the image tag, the URL was
    not getting executed.

    How do I make the webclient execute the img tag?. Is there any option
to be enabled in Webclient?

    Looking forward to your reply

Regards
 Vasu

    Kindly let me know how to enable that?
