How to filter an array of object using a dynamic object?

Question

I have this array of object:

  data = [
          {
            delivered: 118989,
            sent: 132288,
            undelivered: 13299,
            _id: {
              broker: "123",
              campaign: "notificacao1",
              category: "teste",
              event_code: "21295",
              priority: "HIGH",
            }
          },
          {
            delivered: 27,
            sent: 35,
            undelivered: 8,
            _id: {
              broker: "555",
              campaign: null,
              category: "teste",
              event_code: "4494",
              priority: "HIGH",
            }
          }
        ]

and I have an Object witch can be dynamic, with one or more property, like this:

 filterForm = {
      broker: "123",
    }

or

 filterForm = {
    broker: "123"
    priority: "HIGH"
    }

I want to filter the array of object, using the result of the second dynamic object.

Note that I need to filter inside the property _id

I tried using filter.

this.data = this.data.filter(function (item) {
      for (var key in filterForm) {
        if (item[key] === undefined || item[key] != filterForm[key])
          return false;
      }
      return true;
    });

but I always get false

Answer 1

You could use a filter function filtering array by using a loop on dynamic object (in my example is called filterObj):

let myArray = [ { delivered: 118989, sent: 132288, undelivered: 13299, _id: { broker: "123", campaign: "notificacao1", category: "teste", event_code: "21295", priority: "HIGH", } }, { delivered: 27, sent: 35, undelivered: 8, _id: { broker: "555", campaign: null, category: "teste", event_code: "4494", priority: "HIGH", } } ];
    
let filterObj = {broker: "123", priority: "HIGH"};

let result = myArray.filter(el => {
   for (const [key, value] of Object.entries(filterObj)) {
      return el._id[key] === value;
   }
});

console.log(result)

Answer 2

this.data = this.data.filter((item) => Object
   .entries(filterForm)
   .every(([key, value]) => item._id[key] === value)
);
