You should probably write this directly in string form and then evaluate it using JsExp.strToJValue(<your expression>) .
However, the direct answer to your question would be JE.JsOr .
JsIf((JE.JsOr(JsEq(ValById("disable-production"),JsTrue), JsEq(ValById("disable-production"), JsTrue)) , { Alert("Do something interesting...") })
