对rules数组使用filter操作，得到rulescore大于0的规则。

var dataObj = {
 "sitename":{
   "sitescore":99,
   "rules":[
     {
       "rulename":"rule1","rulescore":0,"description":"rules1 descript"
     },
     {
       "rulename":"rule2","rulescore":1,"description":"rules2 descript"
     },
     {
       "rulename":"rule3","rulescore":0,"description":"rules3 descript"
     }
   ]
 }
};

var res = dataObj.sitename.rules.filter((rule) => rule.rulescore > 0);
console.log(res);
