DWR 回调函数获得JSON的值

Question

 public JSONObject getObjectPromotion(String id) {
   HPromotion promotion=this.promotionDAO.getObject(Long.parseLong(id));
   JSONObject jsonFavorite = new JSONObject();   
   EntityConversionJSON  entityConversionJSON = new EntityConversionJSON();
   JSONObject obj  = entityConversionJSON.entityToJSON(promotion, jsonFavorite);
    return obj;
    }

然后报错，好像不接受JSONObject 这种类型，我还想看看JSON的值，不晓得如何打印查看

promotionService.getObjectPromotion(id,function(EcouponInfo){
var json = eval("("+EcouponInfo+")");
}
EcouponInfo为会带参数，也是JSON的值。

Answer 1

[code="java"] var json = eval("("+EcouponInfo+")"); [/code]
不要"("和")"试试吧
