Invoking Cocoon actions via JavaScript
One of our developers has run into an issue that I can't see an easy
solution to. However, I also can't believe that no one else has run into
the problem.
We have a form where we are using IE 5.5 (and above) DHTML to enable drop
and drag editing to reorder fields. As the result of a drop, we determine
some positional values, place these values into the form and then attempt to
submit the form to the server where the values will be placed in a database.
In order to submit the form, the JavaScript code has to invoke the proper
HTML action for the form, which is named using the Cocoon standard
"cocoon-action-xxxx" format. Since JavaScript attempts to resolve the
action name as an JavaScript object it eventually turns a string of this
format into three object names separated by two minus signs and
subsequently blows up trying to subtract non-existent JavaScript objects
from each other.
One obvious fix would be to change Cocoon to not use "-" in the action
names. Given that this would break just about every Cocoon implementation in
the world I'm hoping that someone has run into this before and found a work
around on the JavaScript side of the world?

That's right.
document.anycollectionname["objectname"] should work.
document.all, document.forms, ....

Won't something like
document.formName['cocoon-action-xxx'] work? :-?
IIRC, javascript had syntax like this...

RE: Invoking Cocoon actions via JavaScript

Hi,
You could loop over the form's element array, use a switch statement and use the
name string as a case match to set up your action input element objs in some
kind of body onload init function.
var action_xxx;
var action_yyy;
var elems = frmObj.elements;
for (var i=0; i<elems.length; i++) {
switch (elems[i].name)
case "cocoon-action-xxx":
action_xxx = elems[i];
case "cocoon-action-yyy":
action_yyy = elems[i];
}
}
best,
-Rob
