  var p1=nodeDB.find({"ACTIVE" : 1, "VARIENTS.ACCESS" : "PUBLIC"}, { "VARIENTS.NAME": 1, _id : 0 });
  var p2=p1.fetch();
  var arr1=[];
  var arr2=[];
  for (i=0;i <p2.length;i++)

      arr1[i]=p2[i].VARIENTS;

  }
  var dict=(arr1[1]);

console.log(arr1.NAME);

  Meteor.startup(function () {

结果：

{{1}}

问题：所需的结果只是数组中的NAME参数。如何修改查询？

Answer 1

Mongo查询： -

{
    "result" : [
        {
            "TEMPLATE_NAME" : [
                "Brand",
                "Account",
                "Price"
            ]
        }
    ],
    "ok" : 1
}

Mongo结果： -

for key, value in prices.items():
    print(key)

MongoDb查询访问数组json
