Hi! (For the first time on the list! ;) ).
I tried to create some method, that is added to all form elements, and
simply puts an error message near desired element.
I wanted the function to look like this:
JS: --------------------------
Form.Element.Methods.putError=function(element, msg,
insertn) {
if (!msg.length) return;
insertn=insertn||'after';
msg='<span class="errorMsg">'+msg+'</span>';
var e=$(element);
var err=e.next(".errorMsg");
if (err!=undefinederr.remove();
e.insert({insertn: msg});
};
Element.addMethods();
-----------------------------------
The method is called from 'blur' observer (for some input field) with
something like this inside:
if ($F(e)!=$F(h)) e.putError('This is my error
message!');
After I run the page, everything is fine, until it comes to the line
e.insert({insertn: msg});
in my putError function... I checked it out and insertn=='after' and
msg=='This is my error message'.
Bu in FireBug console I get an error:
insert has no properties
http://mywebpage.address.com/script/prototype.js
Line 1644
More detailed info:
insert(input#ponowhaslo.haslo, Object)prototype.js (line
1644)
_methodized()prototype.js (line 246)
(no name)(input#ponowhaslo.haslo, "<span
class="errorMsg">Podaj hasło (conajmniej 4 znaki)</span>",
"after")prototype.js (line 426)
_methodized()prototype.js (line 246)
checkHaslo(input#ponowhaslo.haslo)prototype.js (line 409)
wrapper(blur )
When instead of insertn I use 'before'/'after'/etc. when executing
e.insert() - everything is fine. But I wanted it to be more flexible.
So I tried to use Hash, to pass it to insert(), but nothing happened:
var h=new Hash();
h.set(insertn, msg);
e.insert(h);
I even tried:
e.insert(h.toJSON());
but nothing happened too...
Also using
Element.insert(...);
has not worked.
Finally I had to use switch/case statement with deprecated
Insertion.Before/After/Top/Bottom instead of insert(), and it works
great, but it's deprecated...
QUESTION:
What is wrong? How should I do this, to make it work as flexible as it
should?
