Tengo una simple calculadora o convertidora de medidas, de longitud y/o de peso. Funciona bien, pero queria aplicarle unos estilos, para que se vea bonita, y de hecho se ve muy bien usando Pretty Forms ([URL="http://www.agavegroup.com/agWork/prettyForms/"]ver aqui[/URL]).
Problema: Tan pronto cargo prettyforms.js
Código:
el estilo cambia, pero la funcionalidad de conversion de medidas se va. $(document).ready(function() {
prettyForms()
});
Usando Firebug veo el siguiente error:
Código:
Solo quiero que lo vean y me digan si es que no es posible que coexistan, mis conversiones y prettyforms. "U2 is not defined"
"if ( U2.options[U2.selectedInd...tedIndex > -1 && isnum(V1.value) ) { "
Gracias!
Mi pagina con las conversiones:
