Enable or Disable Text Field when select option from drop down list

[Douglas Molina]

Hey!!

I'm creating one form y Catalog but i need enable or disable a text field when select an option especifi from drop down list.

So, i have this form:

When i select Cobis in Sistema, i see other 4 options in Tipo so...if i select Firma in Tipo, the vale of this is 2 and i create the field Turno Hidden by default and create this script:

EnableTurno: function() {
       if (cmbAcceso==2) {
       ca_fdShowField(ca_fd.formId, 'txtTurno');
       }
    }

I add this to js onChange attr:

But when i select the value Firma show the numer 2 and not show the field Turno......if i put the script w/out one "=":

EnableTurno: function() {
       if (cmbAcceso=2) {
       ca_fdShowField(ca_fd.formId, 'txtTurno');
       }
    }

Show the field Turno but in any selection of thw drop down list

I solved this with this javascript:

xxx: function() {
var valorselect = ca_fdGetSelectedOptionValues(ca_fd.formId,'cmbSistema');

alert(valorselect); /*To see if i got the value of cmbSistema*/

if (valorselect == 10){
ca_fdShowFields(ca_fd.formId,['cmbFha','cmbFirma','cmbClave']); /*To show*/
ca_fdHideFields(ca_fd.formId,['cmbFha','cmbFirma','cmbClave']); /*To hide*/
ca_fdEnableField(ca_fd.formId,'cmbFha'); /*To Enable*/
a_fdDisableField(ca_fd.formId,'cmbFha'); /*To Disable*/
}
