Subject RE: Invoking Cocoon actions via JavaScript
Date Wed, 18 Sep 2002 15:57:31 GMT
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
