html display problem
I meant that in the function the symbols < and & appear as ampersand codes.

Hi Lucas,
about findChildrenWithTagAndCondition():
1) all “” have a bad editing, so appear as “>” and so on.
2) the function seems to allow the parameter tagName as optional:
if(tagname) do this,
else do that
but in else case, the function still wants tagname few lines after.

did I miss something ?

Jeroen,

Thanks for the tip! I will go and rewrite my code using JQuery. Better do this rightaway before I become attached to my own code. And I like the speed promised with JQuery! (and the fact that it is code that has been tested).

Have you looked into jQuery? I’m afraid you rewrote some of the jQuery functions.

Code sample 1 (http://docs.jquery.com/DOM/Traversing):
Find an Elementâ€™s Ancestor of a specific type (tag):
$(“span”).parents(“p”)
Find all parent elements of each span that is a paragraph.

For the second sample you can use
find(expr) (though I’m not sure about that, but I think it can do what you want)

For showing and hiding you can use show() and hide():
$(“p”).show() will hide all ‘s

jQuery is a really great Javascript library and is only 20KB. Ajaxian recently pointed to an article to show that jQuery also is one of the fastests libraries out there:
http://ajaxian.com/archives/jquery-113-800-faster-still-20kb
It’s usually more efficient to write your own methods (you only write what you need), but I think it’s very hard to write faster code than jQuery.

But still a very nice article, seems I’m not the only Mr. Dojo at AMIS
