I have a plugin where gives me 2 field, country and state by javascript call.
The values for the countries are as follow:
AUT:Austria|\
BEL:Belgium|\
BGR:Bulgaria|\
DNK:Denmark|\
EST:Estonia|\
FIN:Finland|\
FRA:France|\
DEU:German|\
GRC:Greece|\
HUN:Hungary|\
IRL:Ireland|\
ITA:Italia|\
LIE:Liechtenstein|\
LTU:Lithuania|\
LUX:Luxembourg|\
MCO:Monaco|\
NLD:Netherlands|\
NOR:Norway|\
PRT:Portugal|\
ROM:Romania|\
SMR:San Marino|\
SVN:Slovenia|\
ESP:Espania|\
SWE:Sweeden|\
CHE:Switzerland|\
GBR:United Kingdom|\
VAT:Vaticano|\
I tried to hide or show other field used as value the 3 first letters but nothing happen.
So my question is, conditional work on javascript call values?
