Access to element coputed style
Hi,
I wonder if there's any way to get the computed style of an HTMLElement using the HTMLUnit Java API.
I noticed that HTMLUnit does parse CSS but couldn't figure out how to access the parsed info.
Thanks,
Amir

Re: Access to element coputed style
Hi Amir, There's no officially-supported public API to do this, but if hacks are OK then you can do: HtmlElement element = ...; ComputedCSSStyleDeclaration style = ((HTMLElement)element.getScriptObject()).jsxGet_currentStyle();
// use style Note that you'll be dealing with objects intended to be used by Rhino, so all the method names will have the funky "jsx" prefixes, but it should work... Take care, Daniel

Re: Access to element coputed style
Daniel, One additional question. I am trying to read the background-image property of an element using the ComputedCSSStyleDeclaration style = ((HTMLElement)element.getScriptObject()).jsxGet_currentStyle().jsxGet_backgroundImage() method.
It works fine. However, since sometimes the image urls are relative to a CSS file path and not to the html page path, I can't find a way to calculate the fully qualified url for some images.
Is there anyway to do that? Many thanks, Amir On Wed, Jul 29, 2009 at 5:18 PM, Daniel Gredler <djgredler@...> wrote:

Re: Access to element coputed style
Hi Amir, I can't think of a way to do this without modifying the HtmlUnit source code... not even a hackish way. The problem is that you don't know which stylesheet the bg image attribute comes from... so you don't know what the path is relative to.

Re: Access to element coputed style
Daniel, Thanks for your answer. I am wondering if there might be a way for me to modify the CSS files as HTMLUnit download them and to change all relative urls to absolute urls at this phase. What do you think? is there a way to do it?

Re: Access to element coputed style
Hi Amir, Yeah that might work. Maybe try subclassing FalsifyingWebConnection and registering your custom web connection instance with the WebClient. Let us know if you get that to work :-) Take care, Daniel
