I finally figured it out. I had to cobble my solution from piecing together other samples. In the final snippet you hang the data on the This() pointer but in the Google example they use the Holder(). I was trying to get the data from the Holder which has no slot set up for the data and thereby throws and exception.

The problem I’ve been having has been inconsistency among the various samples. You example is helpful but contributes to the inconsistency especially for newbies. I recalled you or your colleagues are working on a V8 Cookbook. That would be very helpful and help advance adoption of the V8 engine.

thx

In my defense, this article was meant to be used for illustration purposes; the reader is supposed to be familiar with v8 and how it works; also, at the time, it was based on the definition of Point that was in the embedder’s guide; this definition may have since changed, I really don’t know. In any case, this was simply meant to expand on that in a rather abstract way. Still, it does look like I was a bit too lazy.

As for v8::Handle::Cast… I seem to remember it existing. It may be a mistake (like the constructPoint appears to be), but perhaps, if indeed it is not in V8, perhaps it used to be and was removed?

I’m sorry for the trouble you’ve had. Keep in mind that this was my first blog post, and is over a year and a half old.

It is very frustrating reading your examples because you didn’t do a good job of explaining the introduction of variables. It also would be helpful to post the entire working code. Had you did that the snippets would have been correct and compilable. Can you please address the aforementioned issued and correct the snippets. That would be a big help to me to be able to get a working sample.

div * {foo}

In your case though you would probably want to set it up as “all the tags in a tag that has a certain class name”, i.e. .filterAll * {filter:alpha….}

Then just apply that className to the item in question.

To the best of my knowledge, the star operator is supported by all major browsers.

I hope this helps.

Hope that helps!
