can you please tell me why this is not working? i got the example for how
to use each online and copied it to a t (except i added the if). its
telling me items.each does not exist.
var items = document.getElementsByClassName(''editView'');
if (items.length > 0){
items.each(function (result){
thisid = result.id;
thiskey = thisid.replace(/se_item_/gi, '''');
selist_toggleEdit(thiskey,''display'');
});
}
You first have to convert it to an enumerable array (use the $A() helper method for that)... $A(items).each(etc.. etc..); The information transmitted in this electronic mail is intended only for the person or entity to which it is addressed and may contain confidential, proprietary, and/or privileged material.

Louis,
document.getElementsByClassName returns a node list. You need to turn
it into an array:
var nodeList = document.getElementsByClassName(''editView'');
var items = $A(nodeList);

oh, i thought it returned an array.... i guess because it worked with a for loop, and i figured that required an array.> Louis, > > document.getElementsByClassName returns a node list.

i tried both solutions and both did not work....
var items = document.getElementsByClassName(''editView'');
if (items.length > 0){
$A(items).each(function (result){
//blah blah
});
}
ERROR: (items).each is not a function
var items = $A(document.getElementsByClassName(''editView''));
if (items.length > 0){
items.each(function (result){

Yea, each is awesome... are you able to use it with a regular array (not a nodeList). Might be worth just testing that to make sure something''s not wrong with your prototype lib...

For what it''s worth, I may have been wrong when I said it returns a node list. I was thinking of getElementsByTagName getElementsByClassName comes with prototype (and other libs) and would probably return an Array. Louis, what version of prototype are you running? Any other JS libs that may be conflicting in some way? -Matt On Mar 16, 2006, at 1:41 PM, Ryan Gahl wrote:> Yea, each is awesome... are you able to use it with a regular array > (not > a nodeList).

Oh yea I didn''t catch that either... so that would make my question about whether or no prototype was running seem dumb...

Try: var editViewItems = ... instead of var items = ... Just to make sure there''s no variable conflict. -Matt On Mar 16, 2006, at 2:08 PM, Louis Walch wrote:> i have prototype 1.4.0 pre_2 > and the only other lib i have is scriptaculous > > >
But he already tried straight
$A(document.getElementsByClassName("blah")).each(blah..);
I don''t use the pre_2 (or whatever) version (only the str8 1.4
release),
otherwise I would check what getElementsByClassName is actually
returning to help more... perhaps you should do the same?

Don''t know... try digging into the code to see what that method is returning though. I would if I had that version of proto.

If you go back through that thread from yesterday, you''ll see that I (and the other responder) made the mistake of seeing "getElementsByClassName" and thinking he was talking about "getElementsByTagName". So we were both barking down the wrong tree, saying you had convert the nodeList into a prototype friendly enumerable array. The OP''s problem turned out to be a corrupted version of the prototype.js file. Not sure how his got messed up, but he re-downloaded it and said it works fine now. ________________________________ From: rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org [mailto:rails-spinoffs-bounces-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org] On Behalf Of Francisco Calderon Sent: Friday, March 17, 2006 6:11 AM To: rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org Subject: Re: [Rails-spinoffs] help with each hello there, what is the diference exactly between the two arrays?
