RE : unencode &# encodings in javascript

[Arnaud Jeansen <ar...@edifixio.fr>]

Hi,
 
We had the same problem here, when trying to inject special french
characters in a javascript string (simple client validation on a JSF
component). The javascript string received a unicode translated value
(é in our case), breaking the javascript code.
onfocus="checkDefaultValue(this, '#{labels.menu_incident_number}');"

The reason why this breaks is hard to identify, I tested as well with simple
alerts on a plain HTML page and couldn't see this happen.
 
We found a simple solution that works for us, replacing the simple quotes by
escaped double quotes:
onfocus="checkDefaultValue(this, \"#{labels.menu_incident_number}\");"

Surprisingly enough, the &#xxx; characters work fine when surrounded this
way. I can offer no real explanation about this behavior, but I hope this
might solve your problems.
 
Bye,
Arnaud

Hi,

I face the same situation. The problem is that MyFaces encodes all HTML and
all messages from the ResourceBundle, so the Javascript alert shows those
annoying &nnn; characters....

I do not know if there is a function but the \unnn notation works 
definitely with alerts:

I am not sure but the #nnn notation might be unicode numbers so they might 
be the same numbers as in the \unnn notation
