[Htmlunit-user] JavaScript question

[Brehm, R. P <rob...@of...>]

Hi,

I have an application that uses javascript syntax that is not supported by version 1.3 as follows..  ssnTableRows[i].getElementsByTagName("td").item(1).style.backgroundColor="white";  The error thrown is the following:

com.gargoylesoftware.htmlunit.ScriptException: item is not a function.

The above syntax does work in IE6 to set the cell background color to white. 

Is there any way currently to tell the javascript interpreter to ignore javascript errors?  That is try to process commands but if the command is malformed or not supported then continue?  If not then I believe this would be a very useful enhancement.

Regards,

The short answer is no.

The longer answer is that this kind of thing would have to be supported 
by the rhino engine and I haven't been able to find a way to tell rhino 
to do this.   All the core javascript support is provided by rhino - all 
we supply are the browser specific host objects (Document, Location, 
Window etc)

Mike,

this can probably be fixed making the object returned by "getElementsByTagName("td")" both a "normal" object and object 
implementing interface org.mozilla.javascript.Function as I've done it for document.all.

I'd read the question as "can I generically tell HtmlUnit to not throw 
exceptions when it hits javascript it can't handle" and I still don't 
know how that would be done.  Perhaps if we caught the exceptions in 
executeJavaScriptIfPossible() and then ignored them if the user had 
specified "suppress javascript exceptions" or something similar.

sorry, I've read this to fast and I was thinking about double access syntas with () and [].
